Magnum MS 2812 Charger/Inverter Issue
I have a 3 year old Coach with the above system. It’s monitored/controlled by a Firefly system, thus, no Magnum Energy Remote Controller which I hate.
Inverter works going down the road, and Charger works if I happen to run the Generator. When I arrive at my destination, and plug into shore power, the system goes into Passthru mode, as it should, thus enabling charging/passthru power. Unfortunately it only stays on for 2 minutes before disabling all passthru power and charging. I can get it back on, if I shut off the pedestal, battery disconnects and then bring it back online. It will stay up and running if I disable the charge side, or the passthru side, but not both. When it does shut itself off, it goes from its standard 117-122 volts coming in, to showing 181 volts coming in. I’m sure this is a fantom reading, but what’s causing it. I have been at multiple parks, so different pedestals. I also use a Hughes Bulldog surge protector on Bluetooth so incoming power is not the issue.
I have spoken with Firefly and Magnum and we’ve tried different things with little change. Connections are all good, I’ve tested the battery bank (individual batteries) and all good. We have also unplugged the bridge between the Firefly and Magnum, thus taking the Firefly out of play, and no change.
Anybody else run across this type of problem.
TIA
