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?<br>
