I'm preparing to connect a 20kwh LiFePo4 pack (when it arrives) to a Solis hybrid inverter.
I've been advised by Solis support that I have 2 options on connecting them (unofficially that is. Officially they don't support DIY batteries).
1 - connect the batteries using the PylonTech option in the Solis menu. Use a Can cable to connect the BMS to the Solis and it should (but not guaranteed) communicate OK.
2 - connect them using the default Lead Acid setting on the inverter, and don't bother connecting the Can cable. The battery parameters can be entered on the Solis and it will then be able to estimate the SOC.
However a friend of mine who built his own battery has told me that there is no point in having a BMS, if it isn't communicating with the inverter because the BMS's only function is telling the inverter to stop when it's supposed to.
So who is right?
