Hello ,
I'm still in the process of builduing my Powewall ( collecting and testing cells ),
but have a temporary Battery allready connected to my two Pips to be able to use solar power a bit.
Atm only everything in my Backjard is running on this offgrid system.
The batteries don't have a BMS jet, they are build of three extended 36V e-bike Batteries ( plus 4 x 6Cells ) to get up to 48Volt.
I check them daily regarding their voltage.
When to much load for this small Battery bank is used ( for example lawn mower and poolpump) , it can occure, that one cell block in the packs gets under 3 Volt.
I would like to avoid such situations, therefore my question:
How do I have to set the parameters in Watchpower that way, that only SolarPower and a minimum to nothing of the Batterypower is used and if Solar is not sufficient, it shortly switches to grid?
Regards
cadric
