Been doing this for 5 years now, multiple systems. Freep mail me if you want to engage me in details.
The grid is a maintenance free battery bank — this is good.
What you pump into the grid in the daytime, you pull out at night — this is good.
Bad — power outage in the daytime means all shuts down, no solar benefit if the grid goes out.
Good — Florida has been writing laws and statues prohibiting any real tax on solar gear on homes.
Bad — home owner insurance provided coverage at the time I build my systems, then cut all solar gear coverage a year later.
Do not use Fronius inverters, they claim 10 year warranty. 3 years out, not honoring warranty.
Bad — Fronius
Very good! I may take you up on that...
