I want to say I've done due diligence and all the wiring is flawless, and that I haven't overlooked something simple or obvious... but I'm not going to take that for granted.
I have a simple system with a multi-plus connected to: the mains/shore (via CB), a 24V (3.3kWh) battery and a heater (as the load) also on a CB. I also have a GX connected.
The behavior I am seeing is this...
- Battery (full) connected, MP in "Inverting" mode (relevant LED on) powering the load.
- AC Mains is present, several seconds pass, MP waiting for AC to become stable.
- MP switches to "Charging" mode (Mains ON and Bulk LED on).
- Insert a wait period ranging from a second through to several minutes
- Then MP randomly turns OFF, all LEDs off
- This (above) sequence keeps repeating
I have a MK3-USB dongle and I have checked the settings so many times
