external chargers for Outback [RE-wrenches]

[John Berdner]

Bruce:
 
The Sunny Island 5048U has a 100 Amp continuous (120 Amps at low
battery voltage) charger in it.
At full power it is right around 90% efficient (as a charger or as an
inverter) and is Listed as a grid interactive inverter as well.
 
Best Regards,
 
John Berdner
