Anyone experience this inverter flickering? By that I mean the voltage seems to vary every ten seconds ish, and it is showing in the lights and t.v.

    I would check for loose connections at the batteries and all cable screw connections.

    I have also had problems with water getting into my main AC panel (this was on utility power). The water followed the wiring in from the weather head (where power lines enter the home) and drop down into a main breaker panel (one home) and into the meter clamps on another home).

    On the AC side, a poor neutral connection/loose or corroded bus bar connections can cause lights to both flicker dark when there are heavy loads, or even flicker bright (if this is a 120/240 VAC Split phase system--faulty neutral connections back to the inverter/main power source can cause all lights/appliances in a home to flicker--Vs just one breaker connection causing problems for one circuit).

    There have been complaints in the past for some inverter brands/models of inverters that had less than ideal AC voltage regulation.

    Is this a new inverter and problem or an old inverter with a new problem?

    With my neutral issues, it was in the main panel or meter socket (after I took all the jboxes and wire nuts apart and re-torqued the breaker branch circuit screws.

    The neutral problems were easy to see. Rust, corrosion, evidence of water in my cases, and evidence of over heated connections (once I cut the utility deal and pulled the meter).

    Check your search mode setting on the Magnum display (ME-RC or ME-ARC) and lower it to 5 watts or less, or add a load (another light) to get it over your actual setting and it will stop flickering.
