[RE-wrenches] More Issues with Parallel Sol-Ark 15K System

[Lou Russo]

Most of our residential off-grid systems are designed around the peak load
so a lot of the time there is extra capacity laying around. I assumed the
fault logic was similar to what Jason is suggesting, 1 inverter faults and
drops out then the remaining "higher level" inverters run and fault on AC
overload if the situation requires it. Guess I thought wrong.
