BatteryProtect 12/24V 65A stops working in -20 deg weather


We use the BatteryProtect 12/24V 65A to stop batteries from being drained too low on some farming equipment that uses solar panels to charge the systems.

We've installed about 100 of these so far and they work as expected. But on 4 separate occasions, we've seen a problem. It seems that the BatteryProtect will unexpected completely stop working (no lights or error code at all) in cooold weather (-20 deg C).

Even disconnecting it from the circuit doesn't seem to fix the issue. The only solution that has fixed it reliably for us is to literally short out the screw posts for a few seconds. This causes the startup lights to flash, and the things starts working about.

We've only witnessed this occurring in very cold weather. The datasheet says operating temperature is -40C, so I'm not sure what is going on.

Does anyone have experience like this?
