I did not think I'd ever end up here, in a solar forum showing off my stuff. But the CV-19 scare made me realize my energy dependence and I started collecting components a couple months ago.
My initial plan was something portable and it worked out well. You can see some details in my 10kWh Portable Tesla Generator thread. Alas 130+ lbs isn't very portable, so I decided to mount everything properly.
I started with my panels on the roof. 260w REC that I have wired up 2S2P for 60 volts and 17 amps. Getting those suckers up there by myself was a challenge! Eventually I used some bolts, large fender washers and wing nuts, temporarily screwed into the factory mounting holes, to hang them on the gutter while I climbed the ladder.
Juice from my panels will run to my garage, where miraculously I have a small blank wall available.
Juice will run through three breakers: PV in from the roof to two 20 amp breakers to break both positive and negative on the way to my MPP LV2424 Hybrid inverter. My battery is protected by two 70 amp breakers. A/C IN and OUT will each get their own 20 amp breaker.
Last up is my wire run. With 50' from my panels to my batteries voltage loss was a big concern. I went with 6/2 MC cable with ground. I got lucky and found it for $1.50/foot locally! 50' of 6/2 at 60 VDC and 17 A will allow for just a .67v or 1.1% drop.
My MPP LV2424 Hybrid inverter is on the way and soon I'll get my other breakers up. I'll post some updates as I go.
Questions, comments or concerns are welcome! Thanks for looking!
