Optimisers give an extra 25% power? no they don't...they do give an extra 50% cost for not a lot of improvement for sure. Granted if you have a roof that has shadows throught the day it's going to help. A lot of boxes though, I have a G100 £1,700 8kw inverter that does backup, export, battery charging and emergency power that takes up the space of your average kitchen bin. Good video 20kwh should be fine without an electric car, might want to get another inverter just for the heat pumps as I found 8kw can get eaten up pretty quick on initial turn on as Heat Pumps settle down nicely after a few hours. A smaller 5.5kw one running direct off batter copes with the 2 x heat pumps we have. Bring on the sun :)
Im considering their system. one caveat tho is that its likley more effeicient to add batteries one at a time, 10kw per year say just because they are inevitably going to drop in price over time. Over the last 5 years and many power cuts we learned that the most we have actually ever used during a 'powercut' was about 13kw. that was about 14 hours averaging 800w and not really cutting back. the other caveat is that 30ms switching is too slow for pc use etc nice vid
Yea that is true, they have a heat pump and rely on off grid power so needs more batteries at once. The time delay on the switchover is quite long. Some others such as Tesla can switch over quickly.
Hi mate! Nearby sparks here from Gloucester. We have a Solaredge 10kW inverter with 30kWh storage and backup interface, pretty much same as yours. One thing that confused me is when connecting the backup interface, you have the two options of connecting neutral depending whether it's TNS or TNCS. How did you connect yours? The wiring diagram for TNCS looks like it wouldn't isolate the neutral connection from grid, therefore not all 'live conductors'? Also, separate note, would you recommend trade mastermind? ;)
Other systems have an almost instant switch over when the main grid goes off; such as Tesla gateway, EcoFlow PowerOcean. Is there any way/configuration to the tell the SolarEdge backup interface to monitor with shorter delay therefore to give an 'instant' switch over to backup battery? I hope this makes sense.
