In the last post, I described the DC charge controller and battery wiring for the Shop Solar System. With solar panels and batteries connected, the inverter was functional. A quick test showed the expected 240 VAC at the inverter output, and it was time to connect it to the breaker panel in the shop.
Continue reading →In the last post, we mounted the solar panel array. Now it was time for the solar power system low-voltage wiring. The array is about 50 feet from my shop, where the batteries and inverter are located. I planned to use two strands of #6 UF direct-bury cable to conduct the predicted maximum of 36 amperes to the shop.
