EG4's in split phase output

Any chance the pv wires have been transposed? + and - from different arrays to single inverter input.
 
Problem solved. I re-installed the bonding screw in just one of the inverters and it all cleared up, I have steady 120V output on solar.
So, I guess those little rascals are important after all.
Thanks Todd.

hi, I have the same problem with eg4 6k now. Started yesterday. If batteries are turned OFF, no issues from ac in to ac out. If batteries only, then I see the voltage fluctuations. Could it be related to bonding screw? Is there a video/instructions on how to change it?

I don't have pv. It was working perfectly yesterday morning. I have 4 wires coming from main panel to inverter and 4 going to sub-panel. I have double verified the wiring and it is correct as it was working yesterday. No response from SS

Easy solution. Don't remove the bonding screws. It's not necessary. It doesn't cause any issues having 2 N-G bonds. It causes issues not having any.

cool..So what could be wrong here? Is there a way to reset the inverter back to factory settings?

If you are still having some issues, DM me your email address and I will get you taken care of.

I just wanted to reply here that I had that just a couple weeks ago, and when both inverters were on and the solar switches were enabled, there were crackling arcing noises from within the solar switches. no harm done to the MPPT chargers, but it was pretty exciting trying to diagnose the issue.
