Theyd be higher for a sunnier location such as Perth and lower for cloudier places such as Melbourne or Hobart. My AS4777.2:2015 profile allows voltages up to 265v (for short periods, and shuts down on 10 minute averages above 258v). In exchange, the customer receives a small rebate on their bill for every kilowatt-hour (kWh) they export. 0000001916 00000 n
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. We have had solar for 6 years and just recently moved homes. Can I share my power excess with me neighbour? In future, will powercor allow export limit if they upgrade transformer? How is export limited for micro-inverters? Also, if you are on the main grid the amount of power you are allowed to export can still be below the limits given or even zero, depending on how much additional solar capacity the local grid can handle at your location. This is sufficient to charge a battery, although larger solar systems generally improve the return from batteries. The data has 5KW flat lining confirming more is being generated. 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! 0000009573 00000 n
What am I missing? Of course, if you are planning to get an electric car, that has the potential to make a huge difference to your self consumption of solar power. 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. 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. 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. Since in WA you cant have more than a 5kW inverter on a private residence, I believe there isnt actually export limiting in play, and the inverter itself clips the output AC regardless how much the panels are generating, sadly. you aren't allowed to export any power from your solar system to the grid. At the moment a battery system is unlikely to pay for itself, but you could install a system that is larger than what makes financial sense for your current situation and hope home batteries will fall in price over the next few years. I have solar on my house and having it installed at an investment property, but not sure what to do now as there will be no benefit of feed in tariff. Queenslands Ergon network area: All of Queensland on the main grid outside of South East Queensland. Exporting surplus solar power is good because it reduces fossil fuel generation and pays you a feed-in tariff that reduces electricity bills. Some networks will allow larger sizes than those outlined below, pending specific approval from the network. 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. essential enrgy in central west nsw (Orange) are generally restricting to max 5kw export limit regardless of 1ph or 3ph: 2 x 3ph residential applications approvals cutnpaste below only difference was one specifically stated APPROVAL/SITE SPECIFIC CONDITION(s): Total Site to be export limited to 5kW 3 phase 1.66kW/per phase (and the padmount sub for the subdivision in on the property boundary) Single-phase properties can have up to 5 kilowatts of inverter capacity, and 3 phase properties can have up to 30 kilowatts. Im afraid thats a tough situation. When it says that you can export 5kw, does that mean you can export up to 5kw PER HOUR?

So far I have not seen much more than 5kW DC anyway, but in summer I would expect to see a curve thats flattened at the top during the high sun phase, as it is cut off by the inverter. ) 0000017636 00000 n
You could contact Powercor and explain your situation, but I suspect theyll say you need to be an installer to check if an increase in export capability is available. Real names are preferred - you should be happy to put your name to your comments.2. Now, that would help protect electricity grids, especially, the fragile, decrepit SWIS grid, for the present. 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 . The word first can be confusing. Voltage (V) measured at inverter terminals 0000038218 00000 n
There is not likely to be an Enphase system without a gateway (called the Envoy with in the Enphase system), because this is needed to setup the system, configure its profiles and report production and other important functions of the system. 0000037952 00000 n
South Australian solar panel owners can currently export 5 kilowatts of electricity to the grid but under Flexible Exports, they could export double that amount 10kW. Shane, you appear to be mixing up kW and kWh easily done! Rubbing salt into the wound were situations where someone was zero export limited while their next door neighbour wasnt. So-called wasting of the extra electricity produced is irrelevant: sunlight is FREE, and whether I use it or not has no bearing on the environment. 0000029403 00000 n
it is, kind of, effectively export limiting. NSWs Endeavour Energy area: Western Sydney. . 2. Victorias AusNet network area: The eastern third of Victoria, not including Melbourne or French Island. I am trying to get a system installed (6.5k smart hybrid inverter with a battery) and have been told by Western Power that I am limited to a 3.0 kva system. Heres the Fronius Smart Meter that you need if you want to export limit a Fronius inverter it will add about $500 to the cost of the system: An example of how export limiting works You have an inverter thats exported limited to 5 kilowatts. If thats not a good option, you can consider getting a demand tariff and doing pumping outside the peak period when the cost of grid electricity will be relatively low. March 2022 6 Powercor means Powercor Australia Limited, ABN 89 064 651 109. portal means the eConnect portal for CitiPower and . It is possible to max out the 10 kW inverter capacity with my Tesla, house load and Heat Pump hot water. is it 10kW AC or DC?? 0000007057 00000 n
So my understanding of the info above is that my inverter will increase production in unison with demand until it hits 5kw? This applies to both single-phase and three-phase properties. 220 352 0 obj

"Some of these customers may have received approval to export since, due to network improvements made since their connection." So if an inverter that is export limited to 5 kilowatts is providing 8 kilowatts of power, none of it will go to waste provided the home is consuming at least 3 kilowatts at the time. hbbf`b``3

On the main grid, single-phase properties can have 5 kilowatts of solar inverter capacity, and three-phase properties can have 15 kilowatts. While there are some energy management measures that could help around the edges, I cant think of any good solutions for the typical business. I prefer a profile that just has the voltages set to a high voltage threshold, and if I have to sacrifice V-W mode, so be it. So if an inverter that is export limited to 5 kilowatts is providing 8 kilowatts of power, none of it will go to waste provided the home is consuming at least 3 kilowatts at the time. Unfortunately, the meter companies and inverter manufacturers cant get their shit together, and the utility meters refuse to talk to the inverters. 0000027818 00000 n
Please make sure you engage early with our team through eConnect to check on network capacity for your customers. If you are using Enphase microinverters which is extremely likely the whole system can be export limited using the Enphase Envoy gateway. I have a new residential PV system in Perth WA, 6.6kW total panel capacity and a 5kW inverter (Growatt Min 5000TL-X). I could not convince him that I knew what I was talking about! Now, there are quite a few profiles on offer that can be programmed into the microinverters. Australian network service providers (including CitiPower) use solar export limits to keep voltage levels in transmission lines operating within safe . In reality, the losses will be considerably less. Also, given that export limited inverters (supposedly) work the same, regardless of the grid to which they are connected, why is it so, that states have different rules whereby some allow export limited inverters, and, some do not? About CitiPower and Powercor FACT SHEET: SOLAR EXPORT APPROVAL Set appliances to use your solar power Maintenance and safety checks are important &K?BK:T$A1Cn I have spoken to one installer , but he couldnt really help me . 44% leading 0000037686 00000 n
Below is the email response I received from Powercor. Please stay on topic. Export limiting generally isnt permitted. Victorias CitiPower area: The Melbourne Central Business District. I suspect that it is likely, that that they are all signaled equally, not in truth I dont know for sure. 0000029011 00000 n
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. I have just had a 6.6kw system installed with a Fronius 5kw inverter and am export limited to 3kw. And for this reasons, I have increasingly seen that it is more challenging to run micros without the envoy which would no doubt be extra code required in later versions of the envoy to enforce implementation of various AS4777 and export limiting requirements that cant be done in the micros alone. Whats the logical and practical way forward? 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. 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. 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. It also allows you to focus on increasing your self consumption which in turn provides a better return on investment. To add to this, in the installer section of the Envoys web server control panel, you can set the profile by which all microinverters operate. Does anyone have similar experience with powercor? 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). 0000027694 00000 n
We installed 4.5kw with a 5kw inverter in 2014. The daily export limit is averaged across your billing period (calculated by multiplying the number of days in your billing period by your daily export limit of 14 kWh).
