0000038830 00000 n Below is the email response I received from Powercor. It owns and operates the states largest electricity distribution network, and is responsible for more than half a million poles and over 88,000 kilometres of powerlines. 0000093063 00000 n Thanks for the information. Just last week, Powercor (Western Victoria) advised that they now have more room in the grid for export. 306 0 obj <> endobj Queenslands Energex area: South East Queensland. (Although they will also allow an additional 5 kilowatts of battery inverter capacity.) Enter your postcode now. Sometimes Powercor can reduce that to a lower figure, or even set a zero-export limit. 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. Assume positive intention.4. The whole system of domestic rooftop photovoltaic systems, needs to be reviewed; by both the legislatures and regulators, and, by the components (especially the inverters) manufacturers. 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. But there will often be times when the solar system will produce more power than can be exported, so some energy will be lost3. 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. Only residential homes with inverters of 5 kilowatts or less can receive the states. We might still be willing to do this all the same, from an environmental viewpoint. While this is fine during the week when we are open, it seems a huge waste of electricity on the weekends when we are closed. Shane, you appear to be mixing up kW and kWh easily done! The solar PV system is connected to the network via an inverter. 2. 0000027818 00000 n Ill upgrade the Endeavour Energy area from Ugly to Bad, since things are clearly not all bad there. Generation sources can be, but are not limited to solar, wind and batteries. Allows installation but has an export limit. I think I was partially wrong about how my PV is connected to the home and the meter. But you may as well just get a standard inverter and send your excess electricity into the grid. Your dedicated meter will inform the inverter, and it will immediately reduce the power, so it doesnt exceed 5 kilowatts1. 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). 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. No matter how badly you may want to export limit your solar system, it can only be done in locations where its permitted. Powercor will respond in one of three ways: Approve the size system you've requested Limit the amount of power you can export to the grid (e.g. All is explained here: http://www.solarquotes.com.au/blog/kw-and-kwh-what-is-the-difference/, ( 5kW per hour is a non-sensical unit unless you want to describe an acceleration of energy! No-one seems to have replied Dirk, so I will try. When a home is exported limited, all the power the solar inverter can produce is available for the home to use. Notify me of follow-up comments by email. 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. 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. Please confirm the maximum export limit in the relevant section of this application.. 0000001916 00000 n 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. About CitiPower and Powercor FACT SHEET: SOLAR EXPORT APPROVAL Set appliances to use your solar power Maintenance and safety checks are important My AS4777.2:2015 profile allows voltages up to 265v (for short periods, and shuts down on 10 minute averages above 258v). 2. 0000029403 00000 n So having a powerwall is way less useful for helping with an export limit than you would think. 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). 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! 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? MPPT2 always shows better performance than MPPT, usually quite significantly better. 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! Would the gateway signal the micro inverters to shut down one at a time, or to all reduce output equally? Powercor wrote back with the following response:"Due to the size of t . 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? An Update: I just had system installed 4 days ago in the Energex DNSP and suggest the above is perhaps not quite correct. While the Envoy is an important part of the system, the micros largely operate independently of the Envoy, and in a lot of cases can work without the Envoy at all. We have had solar for 6 years and just recently moved homes. I think of it like the rate at which water is flowing out of a hose. Plus a Tesla Powerwall 2. While export limiting is possible its not always approved. I was told to set Power Limit to ON. Thanks Steve 0418 815 193. In writing I was advised: We want to add a battery and it seems logical to add more cells also to another inverter/battery setup. Typically in the Powercor area, the export limit is 5kW of exports for each single-phase household solar PV system. 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? 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. This is often referred to as 'network constraints'. I have just had a 6.6kw system installed with a Fronius 5kw inverter and am export limited to 3kw. 11kW panels with 10kW 3-phase inverter (Fronius Symo + Fronius 3-phase meter). Its also worth taking a look in case you shied away from installing solar panels in the past because of the situation now might be the time to revisit the idea. If they face in two or more directions, it will further reduce the losses by reducing the peak solar output while stretching it out, so it lasts longer through the day. Hello. I got a question about export limiter that I hope to get some answers from the community. 260 Im in regional WA with a rural 2 phase supply. Self confessed newbie to the mechanics of Solar so bear with me. 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. 2. In future, will powercor allow export limit if they upgrade transformer? It is possible to max out the 10 kW inverter capacity with my Tesla, house load and Heat Pump hot water. Powercor is telling increasing numbers of households looking to install new systems in this area they will have a zero export limit. The 7kW charger achieves full charge in 6 hours, and one embedded generation system to the CitiPower and Powercor low voltage networks. There are versions without this consumption monitoring (old Non -s version of Envoy and even the Envoy-S without consumption monitoring). 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, I think the installers like the Volt-watt modes, because if you dont know where to look they hid the problem at your expense anyway. 0000010080 00000 n Solar Analytics confirms in this scenario its only exporting up to the limit; 3kw. (2nd one APPROVAL/SITE SPECIFIC CONDITION(s): Total Solar Export must be limited to 5kW). 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. If that doesnt worry you then you can get a battery and just hope it mostly pays for itself. %%EOF Its only possible to go larger with a zero export limit: https://www.powerwater.com.au/customers/power/solar-power-systems/pv-class-requirements. Normally single phase properties can have up to 5 kilowatts of solar inverter capacity and 3 phase properties can have 15 kilowatts. Swearing revenge, he began his lifelong quest to reduce the harm the environment could cause. Do you know the situation here? In an Enphase system, that is with the Envoy-S with consumption monitoring. Larger inverters that are export limited are allowed on a case by case basis. going back into the grid with no batteries. All these profiles need to dance carefully around the problem. I wouldnt drive anything else. Please keep the SolarQuotes blog constructive and useful with these 5 rules: 1. 0000008043 00000 n And yes 5kW export limit applies May I suggest an extra fact check to polish the valuable story above? Some manufacturers may have this pre-selected. South Australia Power Networks (SAPN) area: SAPN is the only distributor in South Australia. Ronald 3. it is, kind of, effectively export limiting. If you cant store the power (too expensive) and you cant export it, why the requirement (or desire) to put in large systems? 0000039018 00000 n Powercor says the Solar Hotspots initiative is the first stage of a five-year Future Networks program to support customer investment in solar power systems, electric vehicles and battery storage. Real names are preferred - you should be happy to put your name to your comments.2. 0000007554 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. Am planning to install solar 6.6 kWh system and upon checking with powercor they are giving export limit as 0 kWh. An option is to take your pumps off-grid and run them independently off a separate off-grid solar system.
