No, I would not use a Sol-Ark unless it was redundant, as in two paralleled
for AC output. I agree with you.
That's the other advantage of AC Coupling in a dual Sol-Ark configuration.
If done right the "extra" AC coupled PV can be usable in the event of a
single inverter failure (to an extent). Bu
Hi Jason,
The downside of an all-in one, that may be acceptable for
grid, is in a failure an all-in-one becomes unusable unless there is a
spare. Even with one it is often a bigger job to deal with. This was my
feedback to Schneider when they were looking into this 5 years back. I know
they mad
It's already built - 6 years old - I didn't do it. The new property owner
just purchased a very expensive battery bank and wants to protect it,
understandably, because she had problems with her generator not starting as
expected when not at the property. It was suggested by the original
installer t
Thanks for the info, I'm interested in using it in the Caribbean.

IF this system has yet to be built I would STRONGLY suggest that AC coupling is
NOT considered. IF it is them i would consider HV CC DC coupling.

Hi Mac,
Yes, I considered using a pilot relay - it makes sense to run it on 120V
because relays are readily available. I had the exact same concern - more
to fail.
In this scenario, the inverter/battery room is remote from the house so
there is only one load I can switch easily with a contactor,
Hi Jason,
The only reason to load shed, without using the internal preservation mode
is if you have certain loads you'd like to keep on longer than other loads
that you shed. The various preservation modes can be complex, especially
if you are AC coupled, so you really have to think through your
I just learned from the manufacturer that the mercury displacement relay's
coil is rated for 43.2 to 52.80V. Obviously, the battery voltage can exceed
52.8 pretty significantly. Does the Sunny Island regulate the output
voltage on this relay to 48V or is the actual battery voltage passed
through on
