[RE-wrenches] Automatic load control

[drake.chamberlin at redwoodalliance.org]

I use a Morningstar relay driver and 48 VDC relays to drop loads as the
battery voltage drops. It works fine, and avoids the necessity of
complex electronics.

It's been quite a few years since I've set up an automatic load control, and never with a Sol-Ark. The Sol-Ark will output to the main breaker panel, so no separate "backed up" panel - all house loads will likely be on the Sol-Ark's load side.
