Solar Installation – Part 2


Solar Installation – Part 2

Once the ground wire was routed from the panels to the ground, they were attached to the ground lug in the combiner box. This box is used to combine the outputs of the two strings of panels into a single pair of wires going to the charge controller. There are circuit breakers installed, mostly to use as switches to isolate any problems.

The combiner box had been mounted in my previous visit in June. The conduit from the roof had been run and the wires from the solar panels had been pulled through the conduit.

Once the wiring was complete in the combiner box, I drove a ground rod just below it, and connected a ground wire from the rod to the combiner box. The picture below shows the installation before the lightning protection was added.

Next, I started working on the job-site boxes. The first step was to remove the welded on feet, to make the boxes sit flush with the deck, instead of raised 8 inches above it. This allows them to be used as a useful height bench, and allows for more secure connection to the deck.
