I’ve had this Multiplus Compact 12v 2000va 80amp unit sitting around for about a year. I hooked it up today (I’ve installed a Multiplus in my last two RVs) and it’s unresponsive. I am measuring 13.28 bolts DC on the positive and negative lines. It measures the same on both sides of the built in “mega” fuse. 124.1 volts measured between L and N on AC IN. Same measurement between L and Ground. 59.96 Hz on the AC IN. I do not have a network cable plugged in and there are no other sensors. The AC out is NOT connected to anything but I can’t see why this would matter (maybe it doesn’t detect a good ground on output side?)
All DIP switches are set to off.
Why was this sitting around for a year? Because I took it out of my Sprinter RV and put a Multiplus 3000 in its place. It was stored in a dry garage though.
When I say it is unresponsive I mean: no lights turn on in any switch position. There is no humming or clicking sounds of any kind
Ideas appreciated.
