If I then turn on the coach's engine, and allow the Alternator to come online, the inverter will power on, and continue with no issues. If I try to do this several more times, it has happened a few times that ALL 12v systems are lost(dead), just as if I had switched off the 12v disconnect. I've also noticed that the 12v lights in the RV also 'flicker' when this happens. If I try then turn the Inverter back to ON, the Inverter will come on for less than a second, and then INSTANTLY turn back to OFF. No other alerts or any information to say 'why'. Otherwise, it really looks as if someone had pressed the Inverter's push button, turning it off. This is not a battery level that would set off the LBCO trigger, and there is NO Fault or red light is present. It says: 'OFF', and 'DC Volts 12.5'(or similar numbers). Now, when this occurs, I typically go to the ME-RC remote panel and look at the readout. The instances when this happens, which is ONLY when off-grid with no other external power(such as 120v Shore power or 120v Generator power, or even the Alternator power), the Inverter will operate perfectly for a while, sometimes hours, before pre-maturely turning 'OFF', for no known reason. While I do have a LBCO(Low Battery Cutout) feature on the Inverter, usually set at 11.5 volts, and it has reached that point several instances over several years and will 'Fault' with a red light, taking the Inverter off-line until the batteries come back up to at least 12.5 volts, recently I've been experiencing complete loss of the Inverter, but NOT for low battery voltage. The coach's ATS(automatic transfer switch), and the Inverter's built-in ATS, automatically switch power back and forth depending on which is in play at any time - I lose no power to any devices, tvs, or receivers when this happens, which is excellent! It's all 'automatic' and is designed to minimize the need to monitor them. Normally the inverter performs flawlessly, with the AGS starting the generator automatically, as needed, to recharge the battery bank. It is connected to my battery bank of 4) 6v deep-discharge batteries, in series and parallel for 12v. Typically, my Magnum ME2012 Inverter and ME-RC remote panel perform perfectly when I park off-grid, or while traveling down the road, powering the fridge, all electrical outlets, and even the microwave. I have an issue with my onboard Inverter shutting down while off-grid in my motorhome.
