Plugged it in and worked great able to read L1 and L2 amps. Plugged in generator and unit would not let power to RV. Got fault on display, E2. Looked it up and said Open Ground. Called Progressive and got tech right away. Guess common problem when using Generator. Because of the way Genny and RV are wired. Tech said I had to bond the Ground and Neutral together. So had to make a separate box to plug into Genny and plug RV into that. Worked like a charm. All came on.
I usually use an adapter to power the RV off my generator to - 50 to 30 adapter and then an adapter to the generator (Yamaha 4000 watt).
When you say you had to bond the ground and the neutral together - was that in the separate box?
Could you send me some pictures - where do you mount the box - by the generator?
