[RE-wrenches] Midnite Powerflo16 Enclosure Rust Issues

[Nick Lucchese]

I noticed it on just the lid screws on one of my outdoor installs back in
March (northern California). It initially got my attention but seemed very
isolated and my concerns quickly went away as I recalled that in the last
22 years Midnite has never let me down. If something comes of it they'll
stand behind it just like every other time. A 16 kwh battery with all these
attributes is a game changer, no problem bringing up the concern with my
clients and letting them know that the manufacturer and I will stand behind
it should it go beyond a minor visual blemish. Barely 1/5 the price of my
favorite Blue Ion, great days for affordable quality solutions to store
sunshine!
