Just reading up on Magnum's new AC load diversion controller. It looks
like the best option at this point, it provides AC load diversion so you
can use AC loads not DC resistors, and it communicates with the
inverter, so the system has both 3 stage temp compensated battery
charging, and has 2
Hi Larry;
I'm actually looking at the secondary DC array strategy you mentioned as
well. It's all about those lower charge rates in the absorption and
float stages. The DC array could be sized for a charge rate as low as
C50 and probably have enough current to get the job done.
Meanwhile En
HI Drake,
What sort of multi stage relay control are you using?

A question about turning the AC on/off as means of primary on/off control for
this AC coupling question.
Some time ago I was told that most (all?) inverters don’t like having the AC
switched on/off as a means of disconnect.
If I understand correctly this causes the DC internal relay to have to
I'm considering an AC coupled system with Enphase
that would shed inverters a group at a time,
ending up with one still charging until the set point is reached.

I’m curious about what you mean by not doing a 3 stage charge. While PV
charging in coupled mode (off grid), the battery will reach your absorption set
point. Is this triggering the GT inverters to shut off or does the battery
inverter absorb timer run at all? I would think the absorb time

Hi Folks;
I've done more research on the whole AC coupled issue, and one flaw I
found with both the Sunny Island and the Radian is that they can't
really do a full 3 stage charge for the batteries in off grid mode.
They detect that the batteries are full and disconnect the AC coupled GT

The Outback does not dump load it drops inverter string (s) instead

Hi Ray,
With that size grid-tied system, you would want to use a battery based
inverter(s) near the (6.7/0.8) 8000W range.
The frequency shift of the Sunny Islands will work with kicking out the
enphase inverters but you wouldn't get the same output ramping that it
would offer if it was a Sunny B
Yes, we're definitely planning a battery based inverter. The real
trouble is when the generator is charging, its AC power passes through
to the loads and hence to the Enphase inverters.
Also I agree with the other poster about Outback being more cost
effective. I just took a look at their Remo
I cant see this working well without some battery based inverter
