Whats a Good Brand for a Inverter

Do your batts usually have a resting ocv of 13.3v, or is that surface charge from just turning off the charger?

"Test 1 : After shutting the main electric off and running on batts only the batts read 13.3 volts on meter, "

On what meter? A handheld multimeter, or the inverters display?

"even at the solar controller panel, measured at back of inverter the same reading 13.3 volts,"

It is normal to see Vbatt at inverter output, and throughout the entire circuit, when there's no draw.

"so after test the batts voltage went back to 12.90 volts,"

How long after? It can take a minute or so to rebound. Loosing .13v in just 20 seconds sounds like it may have been burning off some surface charge. And have you compared various meters/displays for accuracy?

"We did another test with micro wave and voltage again dropped to 12.60 but than inverter kicked off only after 4 seconds and cooling fan on inverter kicked on"

What was Vbatt after 2nd microwave run?

Hand held meter and yes check right after shutting down main power, also not sure what the batts read after second test but it did not go below 12.60 because inverter kicked off but I believe I did see the solar panel and it said 12.90 before turning main power back on.

Volts came back fast on hand held meter.

I am going to check the low volt shut off where its at.
