NSWs Ausgrid Network Area: This covers East Sydney, Newcastle, and out to Merriwa. 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! And, when battery powered road vehicles with adequate distance capacity (I have read that VW expects to release a battery powered station wagon, with range between charges, of 700km, in 2023 (although, unless Australia wakes up, such vehicles will be unlikely to come to this neolithic country) ) are available, and, even for the rare ones that apparently, already exist in Australia (having not yet seen a battery powered vehicle in Australia, I wonder whether they are simply an urban myth, as to their presence in this backward country), when would they get charged, if people would only charge them at home? is there a inverter that stops power going back It also allows you to focus on increasing your self consumption which in turn provides a better return on investment. Hi All. 0000005359 00000 n Im glad to hear its flexible enough to do that. The MSO helps us manage and keep our network safe for solar customers. Your dedicated meter will inform the inverter, and it will immediately reduce the power, so it doesnt exceed 5 kilowatts1. 100% JackD 1 year ago. 220 The battery is charging from the DC current which is before the inverter. I cant see any reference to the NT. 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. I live in Warrnambool, Victoria. 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. This 80% could translate to an estimated 50,000 current or potential solar customers able to export more solar to the grid. ), 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? This is often referred to as 'network constraints'. Phone, email, give us feedback or make a claim. Amongst other things, AS4777.2015 has some requirements to shutdown on phase imbalance in a 3 phase setup. 0000001575 00000 n Still a very long payback period, but not as long. 0000029403 00000 n Metered and a non metered version. Does anyone have similar experience with powercor? You could buy a battery, charge it on the weekend and export during week nights. 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. An Update: I just had system installed 4 days ago in the Energex DNSP and suggest the above is perhaps not quite correct. I got a question about export limiter that I hope to get some answers from the community. 4. The installer has been able to get the system through WP in the past as the inverter can limit the export to grid to 3kva. 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. Many NSW rural situations are limited to 3Kw export, due to the length of the transmission lines. This seems to be becoming a big problem at least locally. The fact is that Powercor does not set an upper limit on the size solar panel system you can install, up to 30kW. Installers must also follow the recommendations of the inverter manufacturer and they may say the limit for panel capacity is less than one-third more than the panels capacity. Hi 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. 0000008571 00000 n And yes 5kW export limit applies May I suggest an extra fact check to polish the valuable story above? 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. Great article and content on this website 100% Energex doesnt automatically allow inverters over 5 kilowatts to be installed with export limiting, but currently regularly grants permission for single-phase homes on the main grid to install up to 10 kilowatts of inverter capacity with export limiting. Why on earth would I do that if I can help it. 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? 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. So in effect I have two safety guards in place, 1. the 5kw limiter to the grit and 2. the extra Gateway . Were continually investing in our networks and aim to keep customers informed if additional export capacity becomes available in their area. If that doesnt worry you then you can get a battery and just hope it mostly pays for itself. Im on a swer line in rural south Australia. 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. hour of charging is enough to drive 35km.. Ill upgrade the Endeavour Energy area from Ugly to Bad, since things are clearly not all bad there. Its also unusual for a large solar system to have all the panels facing the same direction. But if you dont use much electricity it may need to be very small, as I explain here: https://www.solarquotes.com.au/blog/zero-kw-export-solar/. We installed 4.5kw with a 5kw inverter in 2014. And, no matter how powerful, the members of the legislatures imagine themselves to be, and, no matter how trump-like, they are, they can not stop the future. If we consider a home in Sydney where no electricity is used during the day, and all the solar panels face directly north, then the percentage of output that will be lost due to a 5 kilowatt export limit would be: So even in a worst-case situation for Sydney, an 8 kilowatt solar system that is exported limited to 5 kilowatts will only lose 4% of generation. 0000010603 00000 n But, if you are living in an area where it is required to install a large solar system a situation around half of Australians are in then export limiting can allow a larger system with normally very minor losses of clean solar generation. 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. Victoria's "Hotest" Solar Postcode is 3977 at last look. In writing I was advised: 2. Most systems have mostly N facing panels, so really only generate peak power for a few hours a day (often 10am>2pm approx) Aside from that, when you have high resistance lines, there is a voltage drop over their length. 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. But you probably would not recover the cost of the battery within its lifetime. The solar installer or customer must have sought and received pre-approval from us for the requested capacity of the generator. There are versions without this consumption monitoring (old Non -s version of Envoy and even the Envoy-S without consumption monitoring). 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. 1. and only supply me with power from the grid I am on my second Tesla EV and the new one has a rage of 700km if youre not a lead foot. sonnenBatterie Evo. Notify me of follow-up comments by email. amended or replaced from time to time. Thanks. (2nd one APPROVAL/SITE SPECIFIC CONDITION(s): Total Solar Export must be limited to 5kW). 0000038030 00000 n After all, Im a big picture kind of guy. 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. Despite the low feed-in tariff you will receive it can still be worthwhile, especially if you can shift some electricity consumption to the middle of the day. I think is is utter madness that the VIC government is handing out generous rebates of $1850.00 and 4 year interest free loans of up to $1850.00 and Powercor has zero feed in capacity for excess solar power. Residential properties are unlikely to be allowed to use export limiting to install even larger inverters. Origin offers 8 cents per kWh until a daily export limit of 14 kWh is reached. 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). 11kW panels with 10kW 3-phase inverter (Fronius Symo + Fronius 3-phase meter). Here at SolarQuotes, we had been hearing quite a few complaints about Powercors zero export limits. How to correctly configure inverter settings. Worried the impact this will have currently when we charge an EV in the near term. I am not sure whether it has been explicitly explained, but, what exactly, is the limit of panels generating capacity, that is covered by the federal solar panels rebate? 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. 0000038830 00000 n 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. 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. 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. 44% leading So, if a contractor or tradesman, using one of these during the day, or, another type of worker, gets home after work, and, plugs one of these in to charge, an immediate drain of 7 kW (I believe that it is actually 7.4 kW), and immediate significant drain is imposed on the grid, for several hours, during peak demand.
