Diesel Generator with variable frequency incompatible with off-grid inverter

The generator with variable frequency does not connect to Axpert King of Voltacon V5

Answer

Axpert King is with the Online UPS topology. Due to this reason, the requirement of DG performance is better than Axpert models. It’s due to when the Axpert King is working in Online mode, the inverter needs to do the phase lock. If the output frequency of the DG output is variable then the Axpert King could not lock the phase then it would not switch to Online mode. You could set the Program 10 to ECO to see if the inverter would work in Bypass mode to charger the battery or not?
