Hopefully someone will find something useful. I jumped off the Will Prowse (thanks Will) springboard and this is my completed backup solar system. Here is a few specifics:
1. LV5048 5KW 240V split phase inverter. 72watt idle power
2. 8 battleborn batteries in this aluminum C&D (cheap and dirty! hinges put on with pop rivits....but otherwise clean and nice aluminum) Chinese tool box. used 1/0 wires as recommended by MPP. Box link: https://www.amazon.com/gp/product/B01BRDW0VA/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 The batteries provide up 9.6 KWHR.
3. I used a 30amp DPDT switch on the input to switch between generator and utility line in
4. I used a Victron 712 to figure out what is happening
5. The 240 LV 5048 output is totally isolated to 10 critical circuits in the house by a transfer switch. I have built this system separate from a more expensive 20 panel on grid net metered system which I had installed. Building a separate backup power system allowed me not to cut into the main system and void the warranties....since its totally isolated. Well the input "TO" the lv5048 does come from the grid.
6. The mount for the solar panels is constructed out of primed, latex house painted pressure treated wood. I used a 2" galvanized pipe as a rotating spit for panel inclination with a small wench to tilt it (not really necessary but is convenient). Since the pipe weighs a lot I bought a 10' section and 5' section and coupled them. Used pipe caps on ends to keep the bugs out. The panels are bolted to a 1/4 X 1 1/4" flat steel that has a 4" X 4" l bracket welded to it. The 4" X 4" provides mounting for to the 2" galvanized pipe. The panels were safely lifted with tie down straps and a carabiner ring on the end. the carabininer if put on the tie down straps provides a ramp to pull the l bracket on mount over the galvanized pipe.
So far because of chimney and roof shadows I may be generating only a couple KWHRS a day....but this is winter and I guess I will get 5-6KWHRs in the summer when the sun is overhead and there is more daylight. I can always charge the batteries with my generator if need be. It a honda 3000 which I have modified to burn propane, natural gas from the house and of course gasoline. I bought the very large size propane tanks (5' size?).
