[RE-wrenches] Generator auto start

[penobscotsolar at midmaine.com]

Can anyone point me in the direction of a good, autonomous generator auto
start. We have an off grid system with a substantial array (8 kw) and
using a dual OutBack 3648 PP, but we have not had good luck with generator
auto start using the relays and Mate within the OutBack equipment. I would
like to try something whose function would be to sense battery voltage and
start based on adjustable settings. Any favorites out there? The customer
has a new Onan 12 kw gennie.

Thanks,
Daryl
