System, EG4 6000ex 48v
battery bank of 6 Eg4 lp48v batteries.
System works well with pv charger when the is sun and inverter supplys the breaker box with 120v.
Problem came up when generator was connected to inverter ac input side.
It did not like my dirty power and would not charger batteries.
Installed new EG4 5000w charger, Turned everything off to install cables.
Have cables from inverter and charger at opposite ends on buss bar in cabinet, ie pos on top neg on bottom for inverter and pos on bottom and neg on top for charger.
Inverter off, pv panels disconnected, Battery bank has 3 battery's with 2 green and 3 with 3 green status lights lit.
Turn on gen and preset charger to Will's settings for Eg4 48v all good charger goes into charging mode light flashing info panels shows charging.
watching it and all seems good, Till the batteries start dropping green lights not adding like they are charging.
What the **** 2 minutes later and more status lamps go out.
Panic mode.... Turn off charger and they seem to be stable but lower than starting point.
Wait 5 minutes and turn on pv connect, inverter connects and batteries start charging like normal.
Am at the point where I am pulling what little hair I have out.
First charger I ordered would not work at all and it was returned to sender.
Now this one shows its charging but the status lights on the batteries are going backwards.
Have been running a cheap 12v system for 2 years without a problem.
Any ideas on what I missed?
