Sounds like a basic generator issue. Use another gen for test !

Hey wrenchers,
I have an off-grid customer with a pair of VFX 3648 inverters, a FM 100
charge controller and two eVault classics in open loop. The issue is
when the generator is charging the batteries, incoming amperage is all
over the place and periodically, gradually drops to 0A then ramps back
up. This is creating really long generator run times. When I turn off
PV input, same results. When I turn off both PV input and charge
controller output (turning off the CC entirely) the inverters hold a
steady charge. If I remove the charge controllers comms cable from the
hub, they both play nicely and charge cooperatively. This obviously
sounds like a communication issue, but unfortunately, without the help
of OB tech support, I am left speculating. I have checked all settings
with a fine comb and nothing looks to be out of place. Has anyone
experienced something similar to this?
Thanks!
Chris Sparadeo
