powercor solar export limit

I am a bit confused about export. I have 3 x PV systems on one phase. Finally! As per current standards, a single phase premises is limited to 10kW generation and 5kW export. Thats a furphy from go to whoa. Can I share my power excess with me neighbour? Wyndham new Solar - powercor's zero export limit - Solar PV discussion Efficiency has and will improve further over time, but never to the point of perpetuity. Smart inverter settings | CitiPower & Powercor The power is first used to meet household consumption, with any surplus exported to the grid for other people to use. 0000037764 00000 n PDF Powercor, CitiPower & United Energy It is delivering 8 kilowatts of solar power. The distributor deals with that by putting the voltage slightly up at the sending end. Im surprised this hasnt hit the mainstream media yet. Your meter is on the connection between the mains network on one side and the combination of your inverter and your loads on the other side. Its located in Ausnet Services' Distribution Area but Ausnet is not part of the CitiPower, Powercor and UnitedEnergy . Am I wrong? Self confessed newbie to the mechanics of Solar so bear with me. ARTICLE WRITES: Queenslands Energex area: South East Queensland. (Or at least it will be expensive to set up well. That is correct. My sister has the same type of inverter (Goodwe) but she lives in the Estern suburbs of Victoria and she has been exporting but her Power Limit was set OFF. 0000001260 00000 n The new inverter standard AS/NZS 4777.2:2020 has new inclusions to address grid stability issues - a new feature that is necessary to further enhance the hosting capacity to accommodate more solar and renewable energy systems. All I can really suggest is to try to shift power use to the middle of the day and hope mainly solar energy is consumed. 220 0000027694 00000 n Would the gateway signal the micro inverters to shut down one at a time, or to all reduce output equally? . More information about the program and how customers can get the most out of their rooftop solar is available at www.powercor.com.au/solar-energy It does this by adjusting the MPPT but instead of working to maximize power from the panels it reduces it. Rooftop solar | CitiPower & Powercor Please stay on topic. Real names are preferred - you should be happy to put your name to your comments.2. Ready for some quotes? In my case, I have N & W facing panels, My inverters clip to 5Kw for a few hours, but I can still export a reasonable amount. 5kW times the number of hours is the total production over that time. I guess it would be technically possible to have a solar system with a battery but still be connected to the grid as backup. 0000038296 00000 n hooked up to an energy efficient 44kW motor for a real-world It seems so strange that it is clear government policy to get more solar going and yet the network operators are effectively blocking it now. We are on a zero limited export. Youll also start receiving the SolarQuotes weekly newsletter, keeping you up to date on all the latest developments on Australias solar scene. While there are some energy management measures that could help around the edges, I cant think of any good solutions for the typical business. Some households lose 20 per cent of their solar output from grid While I dont know where you are a 4 kilowatt solar system should produce an average of around 18 kilowatt-hours a day in WA. 2. There are two options: 1. We respect your privacy and you can opt out from the newsletter at any time. 0000004059 00000 n Victorias Jemena network area: A small but crowded chunk of North and Western Melbourne. VAr (var % rated VA) Anyway you are probably not supposed to be messing around with the profiles without agreement of your DNSP. In looking to the future, regardless of whether we like it, in spite of, and, despite, the great efforts of the WA state government, and its parent, the Australian feral LNP/ALP government, battery powered road vehicles will come to Australia, and, displace ICE vehicles. This is often referred to as 'network constraints'. Means that it caps the amount you can reduce your bills for power used outside of daylight hours? In future, will powercor allow export limit if they upgrade transformer? People have done it at fairly low cost with second hand panels and a DC pump.) As discussion of the topic of export limiting, is continuing, what,if any, is/are the direct effect differences to electricity grid load (as in the load on the wires, not the load as the term used for meaning demand), between a 5kW inverter, and a 10kW inverter with 5kW export limiting? Weve got a system that can be left alone in my opinion, so adding say 6.6kw and a 10kw battery makes good sense but what a task. 0000027818 00000 n Depending on their location, some may be constrained to a lesser export level or even no exports at all. This could be important, given that we have a state parliamentary election due in a couple of months. South Australia Power Networks (SAPN) area: SAPN is the only distributor in South Australia. Just last week, Powercor (Western Victoria) advised that they now have more room in the grid for export. I have 13.25 kW of panels with a 9.8 kW LG Chem battery and a 10 kW inverter export limited to 5 kW. As a general rule, 5kW tends to be the upper system size limit for single-phase connections, but some networks allow up to 10kW. Can one have micro-inverter panels without a gateway, and how would that be limited? Does anyone have similar experience with powercor? I have a 14kW solar array running Enphase IQ7+ microinverters (43 of them) hooked up to the grid in a 3-phase configuration in the Endeavour Energy area in NSW, and they currently have the profile AU default AS4777.2:2015 30kVa, Vv, Vw set. One thing I find is that Voltage control works well: instead of the inverter resetting if the voltage gets too high, my inverters roll back output, so it actually helps my neighbors too because their inverters reset less often. DC Input Power (Wp) 10000, from its published datasheet. Solar customers who currently have a limit on the amount they can export are invited to contact Powercor to reapply for an export agreement based on the greater capacity now available on the network. 0000038218 00000 n just wondering if anybody can shed some light on the following, So in effect I have two safety guards in place, 1. the 5kw limiter to the grit and 2. the extra Gateway . ACTs EvoEnergy Network Area: Covers most homes in the ACT, especially in built-up areas. In writing I was advised: Im trying to get some unbiased advice on whether or not we should add more solar. Point Cook Solar limit export to zero by Powercor - Solar PV discussion No-one seems to have replied Dirk, so I will try. We have a 3kwh system and are really using as much during the day as we can. Why my Power Limit is set to ON with the % whereas her Power Limit is set to OFF and she has been exporting. The percentage var/VA level leading is the inverter sourcing vars to the grid, whereas the percentage var/VA level lagging is the inverter sinking vars from the grid. Select your country/region. Hello. %%EOF First read the section How Export Limiting Works at the top of this thread. A man named Canute, proved that, centuries ago. Below is the email response I received from Powercor. They want to do it there way and it seems my request complicates things for them and I dont hear back, bar a couple. "Some of these customers may have received approval to export since, due to network improvements made since their connection." ), Finally understand, the article above is very well written for the layman 5kW export limiter imposed on one inverter. Or, if you want a lower cost method of dealing with blackouts, you can get yourself a small generator. Going solar even if Powercor says 'No' - MASH: Community Solar Please keep the SolarQuotes blog constructive and useful with these 5 rules: 1. So while the article suggests 10kW inverter ( 13.33kW DC) in fact the limit seemed to be 10kW DC ( hmmm what does 10kW generation mean exactly ?.) Theyd be higher for a sunnier location such as Perth and lower for cloudier places such as Melbourne or Hobart. 240 Have I been conned into believing I could produce up to 6.6kW myself, but in fact the maximum my inverter will ever allow through to the meter (and to my house) is only 5kW? But this is at least partially because when you throttle back output, you also reduce the amount of voltage rise you are causing on your local connection to the point of interconnect which is probably contributing to the issue. 0000029403 00000 n Where do I find information on reapplying for export with Powercor? Is this perhaps one of the well-kept secrets about the reality of residential solar production in Western Australia, one that neither the solar installers or inverter manufacturers, let alone Synergy or Western Power want to be publicly known? The majority of customers are approved for the export level they request. There are profiles that still conform the microinverters to AS4777.2:2015, but can disable Volt-Var/Volt-Watt, change the power factor to 0.9 (some grid operators require this), turn off export altogether or set specific maximum export levels like 1kW, 3kW etc., or configure to satisfy specific grid network requirements. However they have been advised that this wont be allowed anymore. Thank you. 0% About CitiPower and Powercor FACT SHEET: SOLAR EXPORT APPROVAL Set appliances to use your solar power Maintenance and safety checks are important On a related note, we mentioned yesterday that over the border in South Australia, SA Power Networks is readying to ramp up flexible solar exports in an effort to support more solar installations and its pretty clever stuff. 0000001916 00000 n Youre using a total of four kilowatts to cook your lunch, so your home is exporting 4 kilowatts, which is below the limit. The following is a list of the areas in case youve been missed. Rooftop solar works by turning sunlight into electric power. ( It appears the wire from the inverter is directly connected to my main fuse for the house circuits. So having a powerwall is way less useful for helping with an export limit than you would think. I want about 10Kw of panels so I can run pumps etc. So really apart from the requirement that the initial startup can only happy on voltages below 253v, I have no throttling until at least 285v and probably even higher. Even if I were exporting 100% of it, it still would only bring down my bills by a tiny amount per month. 0000001575 00000 n embedded generation system to the CitiPower and Powercor low voltage networks. While losses increase as the solar power system size goes up, even with 10 kilowatts of panels which is twice the export limit, only 13% of generation is lost. I will update the article with the information. 0000028229 00000 n I have a 10kw Solar Edge inverter limited to 5kw. <]/Prev 115522/XRefStm 1575>> Recent work by Victorian DNSP Powercor on some problematic parts of its network is enabling more solar power from rooftop panels to be exported to the grid. 0000009573 00000 n The fact that export limiting is necessary is not a good thing. I dont quite understand how the DC energy from the inverter can go to my home circuits first, before any excess current is fed into the grid. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Download the first chapter of The Good Solar Guide, authored by SolarQuotes founder Finn Peacock, FREE! 260 Powercor is telling increasing numbers of households looking to install new systems in this area they will have a zero export limit. Some networks will allow larger sizes than those outlined below, pending specific approval from the network. Unfortunately, the meter companies and inverter manufacturers cant get their shit together, and the utility meters refuse to talk to the inverters. For example, if you are export limited, only the Envoy-S with consumption monitoring can provide this. If that is the case it seems counter intuitive to me as I dont know if demand will outstrip production until I actually turn the appliance (eg A/C) on and check the display. So what goes throgh the meter, in either direction, is the difference between what you generate and what you use. While export limiting is possible its not always approved. Has the oppressive authority in WA ever given a reason for not allowing export limited inverters in WA? 100% So, I am pretty much left in the dark about whether all the energy my panels are theoretically producing is being utilised, or (which is my fearful assumption) up to 1.6kW are wasted whenever the panels produce more than 5kW AC. 306 0 obj <> endobj My AS4777.2:2015 profile allows voltages up to 265v (for short periods, and shuts down on 10 minute averages above 258v). 0000011077 00000 n After all, Im a big picture kind of guy. 11kW panels with 10kW 3-phase inverter (Fronius Symo + Fronius 3-phase meter). Ill upgrade the Endeavour Energy area from Ugly to Bad, since things are clearly not all bad there. To give you example, you will probably find the profile you mention is probably throttling from a very low 250v and will ramp down to 20% at 265v. 1. We installed 4.5kw with a 5kw inverter in 2014. I think it is illegal in WA to rewire your inverter or modify any parameters, as it may result in more than 5kW being sent to the grid, so I will just bite the bullet and see that I use as much solar as possible. The reason for this query, is that, in the past, my understanding has been that, in WA, where export limiting is apparently, banned by the gratuitously oppressive state parliament, and, where a limit of a 5kW output inverter, is allowed, for a single phase grid connection on the SWIS grid, a limit of 6.66 kW of panels generating capacity, is imposed for single phase connections to the SWIS grid, and, thence, the limit of panels generating capacity, to which the federal solar panels rebate applies, for such a connection, has been the 6.66kW. 0000004622 00000 n Hi Everyone, How is export limited for micro-inverters? Powercor's network solutions manager Claire Cass said of 32,580 customers connected to solar with Powercor in the last 18 months, only 2023 could not export power. Origin offers 8 cents per kWh until a daily export limit of 14 kWh is reached. The fact is that Powercor does not set an upper limit on the size solar panel system you can install, up to 30kW. Solar Export Limiting: Why You Should Know About It Powercor households stand to save even more with solar Then the information that was left was cut to make the piece more introductory, but perhaps all these reductions made the article like my favorite World War II movie Abridged Too Far. If you are export limited, the only way to implement that is with some sort of meter as Ronald says. As far as I know, only solar installers can apply for export capacity in the Powercor area. Many NSW rural situations are limited to 3Kw export, due to the length of the transmission lines. Very true AL0126. What inverter do you have? Solar Export Limiting or Zero Export. What Does it Mean? Wouldnt it be better for the inverter to display its total actual potential output under current conditions? But if you had a larger solar system with a larger inverter that was export limited to 5 kilowatts it could potentially supply 2 kilowatts to your home while exporting 5 kilowatts to the grid. I am surprised to hear that Powercor has allowed you to increase your exports, but that is good to hear. Export limiting does limit the inverter output, but only as needed to keep the export power below the limit. So yeah, the Envoy is essentially all you need to configure export limiting or anything else if you have an Enphase microinverter set-up. I live in Warrnambool, Victoria. Whilst this may not be technically defined as export limiting, as the inverter specifications, specify that the inverter, whilst allowing up to an overload factor of 2, will only generate up to 5kW of A/C power Thats a huge jump and even a smidge higher than the Powercor network wide average of 89%. But you probably would not recover the cost of the battery within its lifetime. The installation of solar photovoltaic systems as well as the correct inverter settings are critical to ensuring customers get the most for their investment in this technology. So my understanding of the info above is that my inverter will increase production in unison with demand until it hits 5kw? STCs can be received for panel capacity up to one-third greater than the inverter capacity. Powercor wrote back with the following response:"Due to the size of t . In most cases, if you had your envoy shut off, the micros would start and work on their own and independently of the envoy, and in fact of each other. So if your home isnt currently drawing power you wont know from looking at the display if its capable of producing the maximum 5 kilowatts or if it cant provide more than 3 kilowatts. Store it and use it later (this requires solar battery storage), or it disappears into thin air via a heat sink. But your situation is complicated by already having a 3 kilowatt system. Under another option to . Many Australian homes are not allowed to export more than 5 kW to the grid. Thanks for the information. We respect your privacy and you can opt out from the newsletter at any time. Ready for some quotes? so if I was correctly explained to, then I am limited to export less than 5kW (because my existing system will never produce 3.5kW), No installer (or their salepeople) is able to explain to me how the limiter is connected/set up in the scenario where I have 2 inverters. Solar connections for industry | CitiPower & Powercor The current Envoy they will be selling is the Envoy-S. Before that was the straight Envoy which did not have the consumption monitoring / metering needed to do export limiting. You can see from the profile name that it ensures the microinverters conform to the AS4777.2:2015 Australian standard that governs inverters, and it enables the advanced Volt-var and Volt-watt controls for adjusting export power when the grid voltage gets too high (as opposed to abruptly shutting off all export power when grid voltage is too high, which happens without Volt-var and Volt-watt). I know in the movie the Bad was worse than the Ugly, but thats not the way Im doing it. To me it does not quite make sense as no system can produce 100% of its capacity meaning my existing 3.5kW will never produce full 3.5kW (on a good day, I am lucky to get 2.5kW). Is it the 6.66 kW, as the 1.3 overload factor of a 5kW inverter, or, is it the maximum allowed (by the manufacturer) panels generating capacity, for an inverter that is allowed by a state/territory government? So you may decide adding a second system is worthwhile, or you may want to put it off until your current system develops problems and replace it with one large new system. Regarding batteries, as we all know from our mobile phones, constantly being charged and discharged, will deteriorate much quicker than PV panels (and the same that goes for phones, laptops, and your electric toothbrush also goes for solar and electric vehicle batteries, unfortunately). But I will warn you, even with the high cost of grid electricity and the low solar feed-in tariff in Western Australia, batteries normally wont pay for themselves. Amongst other things, AS4777.2015 has some requirements to shutdown on phase imbalance in a 3 phase setup. Powercor program works to increase solar export capacity for 50,000 Of more concern is occasional spikes in consumption which go past the 5kw limit. Victorias Powercor area: Western Victoria, including a large portion of West Melbourne. 0000005359 00000 n Up until quite recently, Powercor had been informing a large proportion of households looking to install new solar systems they will have to cop a zero export limit due to high congestion created by exports from existing systems. And, depending on the circumstances of each individual household, 10-15 kW of total panels generating capacity, with limiting export to the grid, to 5kW, could provide better for the months with less available solar radiation, to lessen the demand for grid electricity, peaking on a seasonal basis. A Decent Battery From sonnen. Weve seen a rapid growth in rooftop solar systems.With each installation, were facilitating rapid growth in the amount of solar capacity on our network. Any ideas of how I can get a system that is actually going to generate enough power to charge a battery? My guess is that when the Envoy-S sees it needs to throttle due to export limits, it does this by sending the same instruction to all micros to throttle the same amount (but dont know for sure). Is this correct? Actually I made a chart showing the percentage of electricity lines in each state that were SWER but I left it out for the sake of brevity. While installing solar panels can still be worth it under these conditions, its a disincentive, increases payback time and is generally a pretty crappy state of affairs. Note that connections off the main grid are usually far more restricted. The Good: In these locations, properties can usually install up to 10 kilowatts of solar inverter capacity if they have single-phase power and up to 30 kilowatts with 3 phase power. We might still be willing to do this all the same, from an environmental viewpoint. When it comes to the limiting imposed by the electricity companies feed-in regulations, it means that, at any one time, not more than 5kW (100L) maybe be output to the grid (hose), it has nothing to do with the total over a certain period of time. In a Enphase system, only the Envoy can provide this. I think that the limiter can connect only to one inverter and not two at the same time. 0000037497 00000 n He first became interested in environmental matters when he was four years old after the environment tried to kill him by smashing fist sized hailstones through the roof of his parents Toowoomba home. But whether or not extra solar capacity will pay for itself is another matter. Hi i want to install solar with no power Hi All, 0000028638 00000 n According to NT Power and Water they will normally allow up to a 5 kilowatt inverter with single phase power and up to a 7 kilowatt inverter with 3 phase power. Fronius Wattpilot: A Smart EV Charger With A Short Warranty, You Wont Believe How Dumb The NSW Governments New Battery Calculator Is. Economically this probably Is not viable, as our electricity bill is fairly low. Information on whether export limiting is allowed can be found here, but I am going to present the information differently for both ease of use and to make my boss think Ive done something useful. Solar and renewables for installers / RECs - Jemena Exporting surplus solar power is good because it reduces fossil fuel generation and pays you a feed-in tariff that reduces electricity bills. 2. Allows installation but has a zero export limit. xref There are versions without this consumption monitoring (old Non -s version of Envoy and even the Envoy-S without consumption monitoring). We do not prevent customers from installing solar for their own self-consumption. 0 Normally single phase properties can have up to 5 kilowatts of solar inverter capacity and 3 phase properties can have 15 kilowatts. I had applications rejected, and when I asked there was NO course for negotiation or discussion its the RULES is s synopsis of the responses. If you are in the solar industry - try to get to the truth, not the sale.5. Can you provide comment and evaluation of power tracing please. Ronald was born more years ago than he can remember. Hi AS4777.2:2015 has some rather low default recommendations, which can be tweaked up as no doubt my profile has allowed. 0000004823 00000 n Now, that would help protect electricity grids, especially, the fragile, decrepit SWIS grid, for the present. House batteries should have the capability of being set to turn off when they are fully charged and then on towards the middle of the day. 0000007554 00000 n Now, there are quite a few profiles on offer that can be programmed into the microinverters. Please make sure you engage early with our team through eConnect to check on network capacity for your customers. We want to add a battery and it seems logical to add more cells also to another inverter/battery setup. What I find is installers dont seem to like it when I tell them my plan.
