Hi Jay;
Ah, its for load shedding. How come the max input amps setting doesn't
limit the total power drawn from the generator? That should throttle
back the charging rate to maintain full power thru to the loads.
Giving the batteries a 56 v for 5 min and dropping back to float
wouldn't const

I guess my answer is that its way easier to switch one button with easy access
than go deep into the menus and have to change 4 inverters.

I would use Everest Express rail pop riveted to every trapezoid, it will
add a lot of strength to the roofing. You may not bee able to get it any
more though.

Look into the Versabracket. We get quite a lot of metal roofing installed
around here over existing shingles with horizontal 1x4 battens. Spacing is
usually 2', however.

What's wrong with the chargers being on? Just set the charge settings

The one and only EcoGen I installed blew out its
oil in within the first couple hours of running.
It severely damaged the engine. Generac did the
service and ultimately replaced the unit. It had
something to do with the two reservoirs and the hoses.

Dana,
Reaching back into my brain archives, having done a few projects with these

maximum system voltage of 48-volts. They can’t be used on higher voltage PV
