Sine Wave Inverter Anomaly

Better inverters are capable of having the neutral bonded to the equipment ground (which in a RV is the frame and battery ground)..

For those you you can simply wire up a male plug with a jumper from the neutral to the equipment ground and plug that into a open outlet on the inverter.

This is the same "fix" for some inverter gens like Honda which do not have a neutral to equipment ground bond..

This fix will allow the EMS to "see" a bond and allow normal operation. Some EMS systems also have a "bypass" mode which bypasses the EMS function, however you do lose the "protection" of the EMS during that bypass.

But BEFORE adding any neutral to equipment bond you MUST READ THE MANUAL OF THE INVERTER OR GENERATOR to make sure you CAN make that connection.

Knew I'd seen reference to this issue somewhere. It was in the Prog Ind EMS manual.

They say in an RV you should "never bond the neutral and ground together for any reason". Bonding in an RV "will create a ground fault condition and may result in electrical shock and or fire hazard"

Pretty explicit; the neutral and ground should remain isolated in an RV, unlike a house.

So separate from whether the Inverter can deal with it, Prog Ind EMS explicitly says no.
