So its good to read of these "adventures". OUR Glitch was weird and can someone weigh in on it? As far as I can tell the water in the sump crock got so cold the sump pump had a starting problem and tripped a safety. In the attached monitor screenshot you see the pump kick on about once an hour, then an failure, then the inverter shuts off (safety) and the battery bank reacts accordingly. Thoughts? what else could it have been it was middle of night. No other motors or loads activated. refrig is 6 A sump pump 8A starting surge, runs at 4-6A
