Voltage drop to 1200 watt inverter
Getting used to a 2019 new RV with residential refrigerator which is on a Xantrex Freedom X 1200W inverter with auto transfer feature and remote monitor. Bedroom and entertainment receptacles on a separate identical 1200W inverter. There is a Digi Level monitor panel which shows house and battery voltages and I had two 170W Zamp solar panels and Zamp 30 Amp charge controller mounted beside these other three monitor panels.
When parked and no generator, shore power, or load on either inverter the four panels all agree on the voltage of the batteries which are 4 Interstate Deep Cycle RV/Marine 12V Group SRM 24.
When the refrigerator is running (not start up load) the inverter voltage indicates a voltage that is 0.3V below the other three monitor panels showing the battery bank voltage. Inverter shows an output load of 85 to 95W. I do not know the wire size or exact length (yet) but the length is probably 8 to 10 feet.
So my question - Is the inverter input voltage reading accurate enough to believe the 0.3V voltage drop on the 12V input side and is that a reasonable number or should it be a 0.1V loss?
