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.

Hi Ray,
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.
This situation is a short term thing. In this case it is an issue as the
generator cannot handle both the chargers and the load. And he doesn’t want and
I agree to have an additional cycle on the batteries when they don’t need it.
I’m working with OB to find out why this is happening.
Thanks

What's wrong with the chargers being on? Just set the charge settings (absorb
56 v, and absorb time 5 minutes) fairly low. It will lightly charge for a few
minutes, and then go to float.
Just because your customer imagines this to be a problem, doesn't mean it
actually is. Its not going to hurt the batteries or use excessive fuel to go
through a little refresh charge like this, and if the batteries actually are
low, these charge settings will be helpful.

When the generator is auto started, the inverter's charger will be enabled.
After the generator is stopped, the inverter's charger will be returned to the
mode before the generator started. 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.
08:00 Inverter charger OFF
10:00 Must run start -> charger ON
11:00 Must run stop -> charger OFF

HI All,
I’ve got a problem that outback tech hasn’t been able to figure out.

The generator is set to specific start/stop daily timer. This works fine.
The client has plenty of solar for the day, and when he runs his generator he
doesn’t want the chargers to operate.
OK so just hit charge off, and yes the chargers will turn off.
But next day, genny starts up, and the chargers come back on as well.
Outback says that shouldn’t be happening, but it is.
Anybody have this issue or know of a fix?
Thanks
