[RE-wrenches] Large offgrid system

[Phil Schneider]

Jay,

I did some design work recently for a larger capacity system.  You need a
"multi-cluster" box for more than four Sunny Islands, which would add some
complexity and cost.  I liked all the auxiliary control options possible
with the SMA - such as controlling relays for multiple AC inputs.
