I've read many times that two things kill the module. One is heat, and they other is voltage spikes. Heat can be dealt with my placing the
compressor is a better ventilated location, and providing good incoming and outgoing air flow with fans. Voltage spikes can be almost completely dealt with by
wiring the compressor directly to the house
battery, and including a circuit breaker as close to the
battery as possible. Connecting the compressor through a branch circuit is not the recommended method, but a person might get away with it for awhile.
