I have a Northern Lights 9kW 2X120V marine generator with two Quattros (one for each leg of the generator output). When the Quattros are charging/inverting with generator power, voltage drops to around 110V when it's loaded with 50amps.
In troubleshooting this, I bypassed the Quattros and loaded the generator directly with 50amps of load from the boat and the generator voltage did not drop. This makes me think there's something going on with the configuration of the Quattros. They're currently set up as Dual Phase 180 with L2 Floating to Orginal Phase.
Does anyone have an idea what might be going on? Thanks!
