I have some issues with my MP12/2000 on the boat.:
- Unit is connected to a multi control panel
- Inverter works fine
- turn on Generator and apply AC power to the unit, "main" led doesn't lid up
- voltage: 119VAC, freq. 60 HZ
- switch to "Charger only"; intermittently the unit shows "Mains on" / "bulk charge"
- This can last 5 minutes or 5 seconds
- Tried with different current limits; no difference
- removed the multi panel from the system and use the "charge only" mode on the unit; Nothing happens
- The problem occurs with Shore and generator power...
Kinda lost and like to charge my batteries as the voltage is close to 12V
