[RE-wrenches] Outback programing question

[Ray Walters]

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 constitute a cycle,  its really more like the refloat setting 
on Outback equipment.  It actually should bring the batteries a few % 
closer to a true full charge every day without overheating the cells.
I agree programming every inverter separately is a pain, not something 
the customer would want to do.  (I'm still waiting for that app that 
lets us set up systems with a laptop or phone)
Good luck, please post your solution.

The logic is if you are running the generator the Inverter's charger should be enabled. You could lower the charger AC limit to 0 Amps.
