powercor solar export limit

Nobody wants to see solar energy . That would provide both export limiting, and, the incorporation of a battery system (for my household, if we would have a 6.6 kW panels generating capacity system, rather than the 5kW one that we have, something like the BYD LVS 20 or 24kWh battery tower, would, I believe be appropriate), which would provide for energy arbitrage, smoothing both power exported to the grid, and, power imported from the grid, especially during peak demand periods. However they have been advised that this wont be allowed anymore. 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. NSWs Essential Energy area: Regional NSW. In an Enphase system, that is with the Envoy-S with consumption monitoring. Powercor says it has contacted all solar customers within the previously impacted areas to let them know about the companys progress and to encourage them to consider reapplying for exports. My solar installer applied to Powercor to install a 5.4kw system at my Point Cook address. The uptake of solar has surprised the powers that be so they are basically wasting free energy and penalizing the producers in the process. Of course the manufacturers dont want this to be public knowledge and pretend that once you paid for a system you are set for life (yours, not that of the system). The metered version comes with extra current clamps to hook up to the grid side so you can do consumption monitoring and export limiting. Was sure if its been configured correctly or if this is just how it works? 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. Single-phase properties can install inverter capacity up to 5 kilowatts while 3 phase properties can install up to 30 kilowatts. I have a new residential PV system in Perth WA, 6.6kW total panel capacity and a 5kW inverter (Growatt Min 5000TL-X). Typically in the Powercor area, the export limit is 5kW of exports for each single-phase household solar PV system. I think that the limiter can connect only to one inverter and not two at the same time. If you cant store the power (too expensive) and you cant export it, why the requirement (or desire) to put in large systems? ( 0000011077 00000 n We have had solar for 6 years and just recently moved homes. 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! amended or replaced from time to time. 100% If so, it would make replacing the whole system more viable which is exactly what I wanted to avoid (and such a waste!). First read the section How Export Limiting Works at the top of this thread. Note that connections off the main grid are usually far more restricted. Is this correct? (Or at least it will be expensive to set up well. Thats a huge jump and even a smidge higher than the Powercor network wide average of 89%. As such, unless the investment pays for itself within at most 5-6 years, IMHO it is not a good investment/waste of money and natural resources. Some battery powered cars can not be programmed to only recharge at particular times of the day, and, so, if someone drives one to work (that is, if and when battery powered cars become affordable to the working class) and home after work, then puts the car on the charger, the drain to the grid, that would consequently occur, during peak demand hours, needs to be covered. Can you provide comment and evaluation of power tracing please. No-one seems to have replied Dirk, so I will try. Hi i want to install solar with no power An option is to take your pumps off-grid and run them independently off a separate off-grid solar system. 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. 0000038830 00000 n Its becoming common for solar inverters to be export limited, so the maximum amount of power they send into the grid is less than theyre capable of providing. 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. As a single example, the Renault Kangoo ZE van (I think that it is the only battery powered cargo van currently available in Australia) has a 33kWh battery, and, To go further, Kangoo Z.E boasts a Z.E 33 (33kWh) battery, Fronius Wattpilot: A Smart EV Charger With A Short Warranty, You Wont Believe How Dumb The NSW Governments New Battery Calculator Is. In exchange, the customer receives a small rebate on their bill for every kilowatt-hour (kWh) they export. An Update: I just had system installed 4 days ago in the Energex DNSP and suggest the above is perhaps not quite correct. It is delivering 8 kilowatts of solar power. But given average voltages are probably well above what they should be in lots of places, and once you factor in your local voltage rise, and pretty low values under AS4777 etc, there is not much room to play with until the distributors get the act together and deliver us power that better matches the 230v standard they are required to deliver us. So basically the whole local industry is going to be cactus until this is resolved. Contracts and resources for connection agreement, Vegetation clearing requirements for new powerlines, Registered Electrical Contractor resources, Rapid Earth Fault Current Limiters (REFCL), Endorsement for wholesale demand response. This is done for three main reasons: In this article, Ill give a broad outline of how export limiting works and why it can be a good idea. Origin offers 8 cents per kWh until a daily export limit of 14 kWh is reached. Unfortunately, the meter companies and inverter manufacturers cant get their shit together, and the utility meters refuse to talk to the inverters. 352 0 obj <>stream 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. But you may as well just get a standard inverter and send your excess electricity into the grid. Quotes vary and the deal has to be value/advantage logical or whats the point. Or is the energy produced by the panels but dissipated somehow? JackD 1 year ago. Okay, so that heading may be a bit of an exaggeration, but improvements the company has carried out appear to have made quite a difference. P/Prated (%) I am not even sure the inverter would support that, but I fear that sadly up to 25% of the PV energy might be going to waste! Notify me of follow-up comments by email. 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. sonnenBatterie Evo. 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? 0000037419 00000 n I guess it would be technically possible to have a solar system with a battery but still be connected to the grid as backup. ) Victorias CitiPower area: The Melbourne Central Business District. Now, that would help protect electricity grids, especially, the fragile, decrepit SWIS grid, for the present. I can also see specific profiles for other grid networks, such as Ausgrid and Ergon, that likely have specific requirements of the inverters. As a side issue for you, if you (like lots of people) have high voltages issue causing shutdown / throttling, I am not a big fan of the Volt-watt modes, as often these modes will also lower the voltages at which the throttling kicks in. embedded generation system to the CitiPower and Powercor low voltage networks. 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? Im surprised this hasnt hit the mainstream media yet. Website link shows system producing well over 10 kW. I did get on the FiT in the early days for the 66cpkWh, but installed a separate system (which I have since incorporated into my stand-alone system. I want about 10Kw of panels so I can run pumps etc. Im in the same situation, except I have an existing 5kW system. 10kW of inverters with 11.325kW of panels. A rooftop solar system's grid export limit is determined by the local electricity network operator - sometimes on a case-by-case basis, sometimes according to an across-the-board standard, and . ), converting to a maximum of 5kW of AC power, whilst the GW10K-MS provides for up to 13.5kW of panels generating capacity, across three MPPTs (strings? We just had a 30kW inverter solar install for our business and it has been limited to 1.8kW export. This profile also doesnt impose any export limits, because Endeavour Energy didnt require them of my installation (maximum is 30kW for a 3-phase installation, which my one is well under). The standard relating to solar inverters is about to change. Talking of which, the fact often gets dropped under the table that neither batteries nor panels and inverters (being mechano-electronic devices) have a limited life span, and their efficiency deteriorates gradually after only a few years. But you will probably find that there is another setting that it will shutdown when 10 minute average voltage is a measly 255v. . Western Australia Horizon Power area: Regional Western Australia. 0000038752 00000 n By the time he was eight, he was already focused on using the power of the sun to stop fossil fuel emissions destabilizing the climate. 20% 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). Thus, the question arises; if a single phase domestic rooftop photovoltaic system, involving a Goodwe GW-5000-MS inverter, and, 10kW of solar panels generating capacity, is installed (across up to three MPPTs), would the federal solar panels rebate apply to all of the 10kW of solar panels, or, to only the first 6.66 (or whatever is the exact applicable quantity) of the solar panels generating capacity? 258 Below is the email response I received from Powercor. Is there anything that can be done about it? See image at http://www.johnrogers.com.au/battery_charging_noon.jpg, CORRECTION: My 13.25 kW system will not go above the 10 kW inverter limit unless my house battery is charging and then it can go to 13.25 kW. Real names are preferred - you should be happy to put your name to your comments.2. The data has 5KW flat lining confirming more is being generated. A 5 kilowatt inverter will never supply more than 5 kilowatts of power no matter how many kilowatts of panels it has. Export limiting generally isnt permitted. 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. 220 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 Hello.

STCs can be received for panel capacity up to one-third greater than the inverter capacity. 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. Select your country/region. It also allows you to focus on increasing your self consumption which in turn provides a better return on investment. When it says that you can export 5kw, does that mean you can export up to 5kw PER HOUR? So in effect I have two safety guards in place, 1. the 5kw limiter to the grit and 2. the extra Gateway . Swearing revenge, he began his lifelong quest to reduce the harm the environment could cause.
