    Lifepo4 SOC based charging

    Hi, I am using the SOC relay in a Victron BMV 700 to control a contactor which switches the pv panels to my chargers. This way I can charge my batteries with a higher voltage setting and have it stop at say 80% SOC to increase my battery lifespan. This works very well. The only issue is that I...

    MPP Solar LiFePO4 system improvements.

    Just finished an upgrade to my system to optimise things a little. The goals I had were: Prevent the BMS from shutting the inverter down when it goes to high disconnect. Voltage spike caused by BMS shutting down high currents tripped the inverter occasionally. Charge lithiums to SOC not voltage...

    Optimising charge rate and LiFePO4 life

    I have 7kw solar, 2x MS5048, 500 amp smart Daly, 2 amp balancer, 2P16S 280Ah LiFePO4. I am trying to keep my batteries between 20-90% SOC for longevity but I want to get to 80-90% as quickly as possible. Setting up the charging voltage at 56.8v and letting the BMS stop charging at say 53.8v or...
