POWERING UP & MORE TO LEARN
Don’t expect step-by-step instructions. I found all the needed information but chronological steps for start-up or shut-down are not readily available. However, there is plenty of online info where people figured out the best steps. I powered up my inverter with battery power first, then went through the entire menu. Go slow, though it’s pretty easy. A couple of battery voltage settings from the battery manufacturer were the only deviations. Then I turned the solar panel input on and waited for the screen to recognize battery & solar power. I then turned my inverter on from standby to ON. I turned the main breaker in my subpanel on and was powering my house!
I left my utility feed OFF for the time being as I wanted to see how the system would perform. This was now October 2021, in the middle part of the US, so sunlight was waning significantly. I already had a significant shadow of the bottom 20% of my solar panels. I was later told by an expert who saw a photo of my install, that because I mounted my panels vertically, long side up & down, I was limiting my energy output more than the 20% shading. My first mistake, but performance was fine through the darkest days of winter so I did not react to the advice. I feel I need to see how this works before I begin changes.
As to electrical performance, now almost 5 months out, we are so happy with our system. Switching power sources is automatic, seamless and silent. We had a storm power outage and did not know until a neighbor called to point out only I had power. I’ll have to work on that, it was so obvious.Continue reading“Solar-Battery Home Power – Part 2, by Jeff M.”
