What might be interesting to discuss here: how could this chain of events have been prevented? My assumptions: Overvoltage on the MPPT led to a MOSFET becoming shorted and the full PV voltage being present on the output. The BMS disconnected due to overvoltage, so there was overvoltage on the Quatt…

[image] Christian Mock: What might be interesting to discuss here: how could this chain of events have been prevented? The first step in the safety chain is design. To deliberately ignore specs, calculators, exceed voltages and then continue to do so under cold conditions (this being a known…
