I replaced my growatt 3000tl ( needed more power) with a EG4 6500, I am now getting flickering lights and my UPS keep tripping. I measure my voltage from from the inverter and its 119v, but when I measure the voltage from the outlet its between 117v to 118v. This low voltage is causing my UPS to flip back and forth from battery and outlet power. Do you think I have a bad Inverter ?. I have attach pics of the voltage. I am using the same setup as I did with my growatt, no wiring was changed, I just removed the growatt and added the EG4. UPS tripping because of low voltage .
Light flickering.
. Setting 10 on the EG4 show that you can change the output voltage from 120v to 127v but the setting does not seem to take. Any help is appreciated. Thank you
