Can I install a 120 volt receptical at my solar system racking?

First off you will need some type of over current protection (fuse or circuit breaker) to protect a receptacle or something like a remote power cb panel feeding the receptacle.

I do not believe you are allowed to use split the output of a solar inverter going to your house panel and to a separate power panel although you can confirm that by talking to your local AHJ to find out.

Each locality must meet some version of the NEC but also have their own rules which may or may not be more rigid then the latest NEC.

You can't just add an outlet, but what you could do is add a small sub panel to the area. The sub panel would be back fed from the array, and then the main feed would be the backfeed breaker you have in the main panel. Then you could put a few other circuits within the sub panel.

This is probably a strange question best suited for the NEC experts.. I looked everywhere and couldn't find any information on it..

I'm installing a 7.6kw grid tied (ground mount) solar system in my back yard.. The location just happens to be next to a high traffic area where we park the tractor, mower, etc and I would like to install a 120 volt outlet on the racking structure so I can plug in work tools, a battery charger when the mower battery dies, etc.

My system requires a 120 foot cable run from my breaker box to the SMA inverter. While I could have gotten away with 6ga wires, I found some direct burial 4ga / 3 wire w/ground copper cable for scrap prices.

Anyhow, since the 4ga cable is far too large to run directly into the SMA inverter's 3/4 conduit openings, I have to install a 12x12 inch square PVC junction box.. I will put a 3 pole distribution block into the box so I'll have both phases and a neutral available.

I would like to tap off that distribution block and install a normal 120 volt household outlet at the same location. In fact, if its allowed, I might even install a 220 volt outlet for my welder.

Is there anything that prevents this? From an electrical standpoint, I can't see there would be any issues but I'm wondering if there is some NEC code that prevents it.

Thanks!
