New install of MP3k and 400Ah LiFePo4 in RV. All worked as expected for two days, then all goes dead (batteries drained, inverter not passing AC from generator). “Overload” and “low battery” flash simultaneously, apparently indicating a ripple current fault. All connections seem tight. Wires are short. What’s the next check? After solar started adding power, things now seem to work as expected. Why did it fault and not take generator charge?
