I installed my multiplus 3000 over 2 years ago and has worked perfectly.
a few days ago the inverter switched to OFF on its own then restarted and back to ON.
it was only off for about 30 seconds to a minute.
We are connected to shore power on a 30 amp connection and i have the input set to 26amps
Last night it happened again at 4am, it turned OFF then ON again 6 times over a 40 minute period.
I downloaded the info from the VRM and it shows the VEBUS switching to OFF.
At the time of the shut down we had no excessive loads, only about 900 watts from the refigerator.
I turned the fridge to propane, which brought the load down to about 300 watts.
the inverter shut down again
We have a southwire surge guard 50amp surge protector built in, it had no alerts or alarms while on shore power.
Looking at the data, in shore power was consistently 122 v and 60 hz
I cut off the shore power to see what would happen on inverter/battery power alone.
the system worked perfectly and no shutdowns while on inverter alone.
Looking at the VRM data several of the chart have weird spikes and valleys
Please look at the vrm data below, I have no idea why this is happening

VRM screens last 6 hours
See all the activity from 3:42 to when i cut off the shore power at 4:09
This spreadsheet from the VRM download shows the inverter going off 6 times from 3:45 to 4:05
The inverter has been running perfectly off of inverter/batttery since i shut off shore power
Please help with any reasons why this would happen
