Solar Wiring Diagram

RJ, you have been off your meds for several days now, posting cranky thoughts for no reason. Please get back on your meds and get back to being polite. You do have some useful suggestions when that happens. ( I have picked up some good tips from RJ. )

Thanks.

Good, thought I was ok.

The thread was good to this point. His question was answered, and he understood it all.
But I knew it was too good to be true,...somebody just had to complicate the hell out of it. It ain't gonna change, its the nature of this forum.

I have the controller, converter, and inverter negative (-) phases connected to a bus and the bus is connected to battery negative post.

Interruption of the solar converter can also be before the controller, between the modules and controller. It's not necessary, but convenient.

FWIW, I have the solar controller, the inverter, the converter, and the batteries, of course, all on one bus. Circuit protection (fuses) are all at the bus and the battery is fused at the positive terminal.

So it's OK to have the negative wire from the solar charge controller to the negative buss behind the converter and not to the negative battery terminal?

If the inverter's AC output is wired to the camper AC outlets through a transfer switch that wouldn't happen.

But really I thought the OP was asking about the DC side of things.

Why? The inverter and converter should be in in parallel to the batts and can share the same pair of wires.

Not the inverter AC "output" and converter AC "input"! Because he'll be feeding the converter from from the batteries then.

Westend is right, it's nice to have a switch or fuse on the controller input. Just for convenience. Doesn't have to be a fuse. Alternatively, you can climb the roof and undo the MC4 connector - all panels over 160W have it.

Interruption of the solar converter can also be before the controller, between the modules and controller. It's not necessary, but convenient.

Very simply. From the batteries to a disconnect switch then routes to a buss bar. That splits to :
1. Converter
2. Solar
3. 400w inverter
4. Elec Jacks-Bigfoot treated them as an option

So basically everything is in parallel.

2. Solar controller output should have it's own breaker or off-switch between controller and bus.
3. (Maybe) connect inverter directly to battery if this results in a shorter DC wire run. Also, make sure the output is not in parallel to converter input.

Hey Almot, welcome back to the zoo. :) Why? The inverter and converter should be in in parallel to the batts and can share the same pair of wires.
