Can the Outbacks be mixed as ½ or whatever number be GT units and the rest
be off grid so they can charge off a generator or better than that make the
battery charging inverters Magnums, they give more charge for the bucks.
They can feed a load panel on their own and charge the batteries off the
Hi Mick,
We're increasingly running into this how big can you go with battery-based
grid-tie question. Most of the hardware out there was designed with modest
residential systems in mind.
Outback is limited to 2 inverters max in grid-tie mode. 7.5kW. (I'm really
curious what Darryl is
I think you may have some thing there. It a bit out of the box however, At
C/10 one Magnum can handle 1000 AH battery. But the magnums can not grid tie,
so the GT would be left to the Outbacks. Your idea is intregueing however. I
think there is a out of box solution for this problem.
Hi Doug
My 12 stack may not be in compliance today, it appeared to be in compliance
when it was installed. It works, but I do not wish to look to hard at it. It
involved extra and custom work by outback when it was installed.

Excellent input, as usual. Thanks to all.

My original drawing showed three triple-stacks of Xantrex XW6048
inverters...with the note that three may not be enough. That XW architecture
would require splitting up the downstream loads. Just
I have grid-tied and Outback-tied and Magnum-tied to an induction motor run as
a generator, thus making it an induction-generator. The induction-generator
runs at just above 1800 RPM if the generator slows it acts as a motor taking
power from the inverter. If the prime mover tries to speed
I believe Marathon Engine also uses an induction motor for their generator
end, then they control the engine RPM to keep the output voltage above the
grid signal.

Hi Mick-
Regarding the Sunny Island system: you can stack four SI5048U's in a split
phase configuration. Install with an AC1 combining subpanel and an AC2
combining subpanel, so your backup load center isn't fed directly on one leg
by one inverter--if you lose an inverter, you just lose
8 matches
