Hello,
I setup a system to provide battery backup for my furnace. Location is a remote cabin and grid power goes down a few times each winter.
I had a Xantrex 1000 kw Freedom XC which worked perfectly. However, it was too loud, and I found the EG4 3kEHV which is a better deal, so I upgraded.
The EG4 manual reads that the ground will switch to an internal neutral bond when in battery mode. But it does not seem to work. When running on grid power my furnace runs with zero problem. If I cut power to grid, the system switches to battery but my furnace does not run properly and gives a ground error via blinking lights on control board inside the furnace.
I setup as per EG4 manual, with AC output ground on designated screw on outside of inverter. When that did not work, I even tried splicing in a solid copper ground wire to furnace as that is how the Xantrex inverter was setup. Still not working.
Only other thing to try is switching to Romex solid copper wire as I am using a 10AGW stranded wire; but seems that should not make a difference.
I reached out to Signature solar asking if my unit might be defective or if the bonded switched ground does not support my application. No response after a week and some follow ups on my part.
Any insights/help welcome!
Thanks in advance,
Greg
