I'm new to this forum. Looking for some answers to a weird set of issues...
I purchased a Novapal 2000w/12v inverter about 11 months ago from Amazon in the US.
My system is off-grid in a home as a backup.
It receives power from 4x 90AH FLA batteries (in parallel) and a Victron MPPT 100/30 controller fed by 4x ~450w solar panels.
The inverter rarely went over 20% of capacity. It has been running a chest freezer (~65w), a few lights and computers.
This worked, but was under powered if I wanted to use it with additional loads... so I upgraded to an 80A AMPINVT controller.
Unfortunately, now I'm having issues with the inverter shutting down randomly several times a day under both heavy (no more than about 40%) and light loads (10% to 20%).
The display goes blank while the alarm goes off and the sound slowly goes down to nothing over about 10 seconds. I get no specific error messages. I turn the power switch to off and wait 10 seconds and it comes back on.
All connections are tight with heavy duty wiring. No shorts.
I did connect a 160W refrigerator on top of the other light loads (during the day only) after installing the new controller... and it worked for a while until it went crazy and shut down. Removed that new load and now it is doing the same thing with the usual past load... even if light.
Any thoughts?
