Around a year ago my cousin implemented a solar system in our place, and it's been great. As of lately the battery isn't holding out all night when using it after dark, we have a grid power system up to 1320 W, and our after dark usage is being around 1700 W and as our inverter doesn't support peak shaving we manually switch the grid off and rely solely on the battery, which in most cases drains it. As I was looking around I found that I can connect a Pi Zero to my inverter and send advanced commands, but my cousin later explained that it will only send commands that are already supported, so automating a peak shave using home assistant won't be possible. The inverter we have is a Voltronic Power rebranded to SunEnergy, though I couldn't find the specific Voltronic model but I think it's the Axpert VM III 6KVA variant which doesn't exist on Voltronic's products page (1.5/3/5KVA variants exist and are here). I attached pics to the sticker on the side of the inverter that has the specs.
I thought about flashing a custom firmware, but my cousin said that it might not be physically possible to peak shave, and it's risky.
If you guys have any suggestions, on what I can do to use the grid and peak shave at 1320 W which should save power usage on the battery and protect it from drainage.
Thank you.
