HELP!!!!!! with last step of inverter install

The coach panel is connected to the sub panel

The sub panel is connected to the main panel


And chassis earth is daisy chained back to the main panel

Yah, have to agree with that safety issue. Seeing how it's just me and sometimes another adult, I'm pretty safe.

With a big inverter, solar and Li battery, I can and do run the air, which years ago I had a feeling I'd be doing, so I went with whole-house. Also, my first inverter install was a Prosine 2.0, which has excellent power protection for shore AC, so that was another factor in not using a sub-panel.

Sometimes there are kids and non technical users that need a system that is automatic. Otherwise you come back from fishing to a dead battery or the inverter does not work. Then you have 20 minutes of generator hours to get enough charge to run the furnace that night.

I'm curious why you need a subpanel? It is only 1200 watts which is equivalent to 10 amps.

If the trailer in your picture is what you have, I suspect that you too have a "sub panel". If you have a breaker panel in your RV, you have a sub panel by definition.

x2. That's a big job for not being able to remember what not to run off inverter.

Sub panels are **NEVER** Bonded. in fact that is the difference between a SUB panel and a MAIN panel. NOTE the "Main" panel in a motor home is really a SUB panel

Now depending on the inverter you may set it to bond when in inverter mode.

But you do not bond the panels. EVER in an RV. Just the inverter and the generator get bonded. At the inverter and at the generator.

Shore power is bonded at the shore (Park end of things).

Ok, thanks all, that was the only issue holding me up on finish up the install. So sub panel is NOT to be bonded. The inverter is grounded to the frame, the metal sub panel case is grounded to the main panel using 3 wire romex....

No neutral-ground bond anywhere in the RV and not in the new subpanel either.

Only bond should be at the power source such as the main utility panel(not your RV panel). If the inverter internally bonds the neutral-ground as part of normal operation that is OK.

All grounds need to be connected and to the RV frame also. This includes the inverter chassis and the metal subpanel case if applicable.

ok, i'm hardwiring inverter to sub panel then to circuits that i want to operate in rv from inverter when shore power/gen set is off. The inverter has a transfer switch that gets the power from the main panel and if line is hot, the inverter cuts off
