I'd like to see what comments I get on this.?
My LiFePo4 system is that I build in protection like an algebraic equation. Brackets ,inside brackets ,inside brackets.
In the inner brackets I have a voltage controlled switch on the Photovoltaic negative line.
In the next set of brackets I have the charge controllers settings.
In the outside brackets is the BMS settings as last resort.
Like this on 24 volts LiFePo4
(BMS low 20v (Charger Low 25v ( PVSwitch Low 26.5v... High 27.6v ) Charger High 27.7v) BMS High 28.2v)
This ensures that when not used heavily the battery cycles down to at least 26.5v before any charge can come from the panels.
Its disconnects the panels when my battery reaches about 3.5volts per cell
Should something go wrong then the chargers settings will cut off charge to the battery but leave the battery connected.
Should all that fail high or low , the BMS would then disconnect the entire battery.
