[RE-wrenches] Emphase and Warranties and Contractor Liability

[Dave Angelini Offgrid Solar]

Electrolytic capacitors are an incredible electronic component that really
have no business on a hot roof unless designed to be!
There are huge long term design factors that go into their use. We went to
the Moon, anything can be done, but I question why a string inverter is
not the best choice for longevity, or even a 600V mppt charge controller
like I use offgrid.  --Dave
