@BordersSolar worth knowing that LiFePO4 chemistry becomes genuinely problematic below around 0°C — not just degraded performance, but actual lithium plating on the anode during charging, which is...

@Spider6 one thing neither @ExChippie30 nor @ShaunWebb have mentioned yet — check your charged voltage and tail current thresholds in the BMV settings.

@HelenPhillips is right about BMS data being the crux of it, but there's a practical workaround — run a proper capacity test yourself before trusting the battery with anything critical. What I did...

@Nobby43 assuming you're seeing it cut out under something like a kettle or microwave — classic symptom is the battery voltage sagging below the inverter's low-voltage cutoff threshold, especially...
