I would like to know if are there any counter-indications about the way I plan to use PowerAssist.
My main goal is to run washing machine (2000W) + some permanent loads around ~300W. So, in total, on average I would like to run ~2300W during washing machine's program.
I have an inverter Multiplus 24/ 3000 VA, capable of delivering ~2000W, but with temperature derate sometmes I get overload warnings around 1800W or 1900W. I have around 3000W of PV. The idea is to take advantage of sunny days and put the system to work, with priority to solar and getting from GRID that small amount the inverter can't provide. This, without ESS for the moment.
So, I have set on Venus these conditions:
1. If AC load on inverter > 1700W, switch to GRID
2. Maxium AC input from GRID = 3A
3. Disconnect from grid when AC load < 1000W
This will force PowerAssist to work, giving roughly 700W from grid and 1700W (max) from Inverter (Solar/ Battery). During periods of 20 ~30 minutes.
This will save me a lot of € in power bill, while not overloading the Multiplus.
Is this ok? Or am I violating any rule? I don't want to jeopardy the Multi in any way...
