I recently added a second Quattro 48/10000 in parallel with an original Quattro 48/10000. An issue arose where the minimum input current limit increased to 21 amps (10.5amps per inverter) and the backup diesel generator that is already installed is not able to comfortably supply 21 amps. Is there a simple work around that will allow the input current limit to be reduced to around 15amps so this inverter upgrade does not cost my customer a new, larger generator?
I'm curious to know why 10.5amps is the minimum per inverter?
