IM INSTALLING A BREAKER PANEL TO CONNECT TO MY EG4 6000 OFF GRID AND WOULD LIKE TO KNOW IF I USE THE BONDING SCREW OR NOT. ANY HELP WOULD BE GREATLY APPRECIATED.

Is this for the 6000XP or the 6000EX? I’d also recommend having only one neutral-to-ground bond in the system. This bond is usually located at the first point of disconnect or in the main service panel. However, if one isn’t already in place, you can either establish it at the inverter or in the main panel.

Hello folks, I'm new to this forum.
I have an EG4 6000EX-48 and five Lifepower4 batteries. Commissioned the system in December 2022. everything is working well.
However, I've always been puzzled by the neutral-to-ground bonding situation, and today while troubleshooting a problem with an irrigation pump, I noticed something strange.
On grid-based wiring, the line-to-neutral voltage is always the same as line-to-ground. I checked the output of my 6000EX and recorded these results.
L1-L2 = 239VAC
L1-N = 119VAC
L2-N = 119VAC
L1-G = 94VAC
L2-G = 161VAC
These reading do not seem normal to me. I'm pretty sure the bonding screw is in installed, but not sure how to check it without taking the inverter apart.
Please explain how to correct my lack of proper boning.
Thank You

I'm not sure if this will help, but here is a video regarding the Neutral ground bond
Neutral Ground Bond Setting Update for EG4 6000 & 6500 All in One Solar Inverters

I always have neutral to ground bonding at the first panel.
EG4 inverter ground included.
Then it is impossible to get readings you have.
Your ground bonding is missing or super bad.
BUT: The EG4 LL batteries, that is a different subject.
Do not assume just because the Battery-6-rack assembly case
is grounded that now all 6 battery unit cases are properly grounded.
I had to ground every battery case separate.

Thank you, yes, the EG4 video provided the answer. I changed setting # 31 from disabled to enabled which solved my problem. Terminology is a bit confusing, I guess I enabled a bypass of the bonding screw and no relying on the bond upstream in my main grid load center.
But anyway. Thanks, Eric for the lead
