Off grid 15 years in the southern mountains of New Mexico. Self installed Outback 7 kw inverter system along with 3 FM 100s 2 of which are recently gone to hell, just as the company has. 3 each Sunpower arrays, total 10 kw, plus 6 -15 yo Kyocera’s at the well. My county ( larger than some states) has one qualified installer who is way too busy for me. Turns out dope farms can use a LOT of solar. As an artist and woodworker I am always over my head with electronics. But fearlessly moving all to Victron.
