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 Charg...

Update: All connections in the Surge Guard Transfer switch are good and torqued appropriately. Connection/hot/common/ground in main panel all good.
Decided to bring the system online slowly by shutting off all incoming power (breakers) and main 50amp. Turned on the breakers 30 amp for the inverter and then one circuit and I got inverter power. Waited, and brought all inverter circuits up, and all was well.
Next I turned all the circuits back off and then turned the 50amp back on at the pedestal. I have two 30 amp breakers labeled charge #1 and charge #2. I monitored my read outs on my Firefly /Vega Touch specific to the Magnum. When I turned on charger #1 it showed zero on the AC Input Volts. When I turned on charger #2, it initially showed AC input volts at 118, and that the charger had come on (float). After 45 seconds, it kicked off and my AC input showed 184 volts as it has in the past.
I tested both 30 amp breakers on the meter and they both are good.
I’m down to the shore power cord at this point, unless anybody has other ideas.
Thanks again
