A lot of iron. You are your own utility company.

Question: Are your 2 outdoor compressors installed at ground level or are they elevated above grade? What SEER are they?

Ground level. They are carrier infinity 21 but they are 19 SEER rated

Still have 35 more panels and one more big roof to fill if needed.

I like the typo.

Never could understand why grid tied people get confused.

Impressive system $$$$$

I know a couple of small electric utility districts that would love to have as much generating capacity and quality.

After losing a home to a hurricane and a second to a flood, I swore I'd never build with infrastructure at grade. Surprised your ac compressors at grade and not higher. What is your elevation above sea level?

We had to raise the ground before we built. The deck around the house is about 8-9ft from median level of the water, the first floor of the house is 6" higher. Because of the reef barrier at north and low depth at the south we haven't had a big water rise with Irma and any hurricane in the last 20 years I've been here. Historically the highest in the area I live that anyone remembers was 4ft. But there is always possible to get 20' storm surge.

I hope we will not get any major hurricane for while.

Hello,

I’m planning a new installation and I’ve been reading about concerns over salty air from the ocean.

Consequently, I’ve been looking at the sealed FXR series. Are you close to the ocean? Did you take steps to keep the sea air out of your electrical room to protect the Radians?

I’d prefer to use the Radian series but I don’t want problems with corrosion and salt deposits down the road.

Thanks,

Dave

This is a bit late answer. Missed your question back then.
I live next to the water (canal) and maybe 800ft from the ocean.
The electrical room is built with AC and well insulated from elements.
Not only here but anywhere in the world I will advise to install the inverters and charge controllers is a clean temperature controlled room.
The dust and humidity can mess the equipment quickly. with salty air will be even worse. Everything outdoor here on island is not lasting long.

That would be great, if my off-grid customers could afford the structure and power requirements. I just had a discussion with one customer that it was time to put doors on the power building. :grin:
