I have a 5 degree slope and also wanted to have the array match the slope for a 52' wide array. After searching many places for something better I finally used Iron Ridge hardware. To get a permit my array needed to be engineered. The engineer that Iron Ridge customer service referred me to...

I didn't know about this so I looked it up here. 3 or more in parallel needs OCP. 2 in parallel are exempt from OCP. For why, see their appendix B. Thanks.

For my own system, I'm designing for much higher future temperatures wherever I can. My thinking is that with no end in sight of green house gasses we're in for a major thermal ride up in the lifetime of the equipment. In the future when you'll need your solar powered heat pump the most your...

I'm seeing that Sol-Ark has a setting under Grid | Sell Control | Zero Export power where by default they pull 20W (or whatever you set) to help make sure that they push less than zero back to the grid at all times for Limit to home mode. (documented in Sol-Arc 301 Webinar)

240.4(D) reads, "..the overcurrent protection...", but on a DC solar string there normally isn't any "overcurrent protection", at least not a device to do this. Instead the DC wires are protected by the upper limits on solar production capacity via Isc. So how can 240.4(D) apply to solar DC...

"15s" seems to be shorthand for 15 series cells, and "16s" 16 series cells.

I'm also looking for a backup generator to use with my Sol-Ark 15k. Although this one and it's 8000W twin look interesting I can't find any technical information on it, nor any service help available. The best I found was this Chinese web site with many broken links in it.

How do I do this? The manual I found for it is here.
