Hi, I have a multiplus 12/2000 in my solar set up on my travel trailer. Lately I’ve just just been plugging into shore power at campgrounds and have the muliplus on “charge only.”
At the last campground I went to the inverter would shut off like it lost mains/shore power for a second or two then kick right back on. This would happen at least every hour. We moved sites, same issue. The surge protector I use when plugging into shore power stayed lit up during one of these outages. We moved to a third site with a 50 amp plug and plugged into it assuming maybe the power at the park had peaks and troughs in its power and that 50 amp wouldn’t drop as much. We had the same issue but only every few hours... sometimes no issue for 7 hours.
I’m thinking it must have been the power at the campground, and no one else had issues as they didn’t have a multiplus acting as a gatekeeper for the power. We are at a new campground now, and no issues yet for over 14 hours.
Details: no breakers popped, draw did not effect it—it would cut off with the air conditioner running or just a little fan, I have my current limit on my GX control set at 30 amp.
A few questions:
Will the multiplus do that—shut off and turn back on—if current or voltage from the shore power source drops below a certain amount?
What should my GX control current limit be set at? (I have a small 30 amp travel trailer, 600W of solar, 300ah lithium battery bank, and only run the air conditioner when plugged into shore power on “charge only” mode) and what current is it controlling?
Why when in “charge only” mode will the multiplus draw from the battery bank when it turns back on after one of these momentary shut downs in order to power the air conditioner’s compressor? Seems like charge only would mean it doesn’t tap batteries ....
Thank you
