Ground Mount Wire Protection

[SunEagle]

I prefer using micros on ground mounts so that HV DC isn't an issue. Any layman understands 240VAC and its lethal capabilities and AHJ's are not requiring protection since it's all AC / non hazardous DC.

Sorry. That statement indicates to my you have no actual experience or knowledge concerning electricity AC or DC.

All electrical power above 50 volts (AC or DC) can be lethal and have caused deaths from electrocution.

The biggest reason experienced electricians have died from electrical shock is because they have become complacent while they are working with something the "understand" but forget how it can reach out and kill.

Try loading it as an image rather than an attachment. The file is small enough that an inline image rather than a thumbnail should not be a big inconvenience for users.

It's called deer barrier, available at nursery and garden stores in a variety of sizes. Make sure it is UV rated.

Hi Panelmal,

Do you have any images of your plastic mesh install that you could share? I would like to see what that looks like.

Thanks.

I install a lot of ground mounts (and the powers that be are pretty strict with us, bad blood) but if the array is fenced in its always been considered not accessible. If it isn't, we put up uv rated plastic meshing installed tightly over all the wiring below eight feet and haven't had any problems with it. If you use wire meshing you're going to have to worry about future chafing issues and having to bond it.

I would think that there could be numerous requirements to making a ground mount system "safe" depending on what the AHJ says is ok along with your home owners insurance policy.

You would figure a fenced in array would be enough but that doesn't always meet "safety" in everyone's eyes.

Might as well install it in the customers basement and brick off the entry points. It'll work fine, just face it towards a window and use solar optimizers.

In some areas a wire screen enclosing the back of the panel mounts and all wires outside the screen in raceways is considered sufficient. Just touching the front surface of the panels is not a hazard.

What makes it interesting if any of the MC4 connectors are accessible by the electrical uneducated people.

That depends on your state. In NH, if you get injured on someone's property, it's no ones fault but your own. Unless they determine that there was intent to hurt you (i.e. shotgun rigged to shoot at the door).



A 48in fence may not be considered high enough to be a "security fence" but that would be up to local codes. Best to get advice on what exactly would be required in your state.

Means nothing. No jury will take ignorance as a defense. Anyone gets hurt for any reason you own it.

Your only protection is pulling a permit and passing electrical inspections, home owners insurance policy with solar added, and it will require barriers to pass. Even then if anyone is hurt you own it. I have worked in, for, and around electric utilities for year. Utilities have made a lot of kids parents very rich. Those huge security fences and all those huge bright RED signs do not mean squat to a Jury.

Currently my property is fenced in with 48" high, 2inX4in mesh steel field fencing with a stand of double barbed - barb wire on top and bottom. It keeps all of the neighbors cows and horses out of my "yard". However the issue is people are a lot more troublesome and mischievous than cows and horses.

That sounds like a sufficient fence to me.

BUT - if you can walk from the front door of your house to the array and not have to jump a fence, then it really isn't fenced in, is it?

Wait till the cows and horses get lawyers. What do you call a Cruise Ship full of Lawyers at the bottom of the Sea

A good start.

At least Lawyers get more respect than a Drummer.

What do you call a drummer in a three-piece suit?

What do you think 12 of your neighbors would say if a 10-year old got hurt by your array?
IMO if you make it so even if you got sued you'd have no problem winning the lawsuit, then you're set.
Armed guard or razor wire is obviously more than enough.
But a 2' high split rail decorative fence probably isn't.
