Inverter Neutral Connection
The inverter has a floating neutral so the neutral voltage will be close to 110v. In this case
the live voltage with respect to the earth will also be around 110v.
If you use your inverter for a standalone application you need to bridge the neutral input
with the earth terminal on the inverter (these two are next to each other for this purpose).
You can now fit an earth leakage after the inverter.
But if you are going to supply your inverter with AC from the grid then you need to put the
inverter before the earth leakage and you need to keep the inverter neutral input connected
to the GRID neutral at all times.
So if you what to switch the GRID input to the inverter off then one must only switch live.
You can then put the earth leakage directly after the inverter. The grid will pull the inverter
neutral to 0v.
