I also worry about getting the system
to 64 hz.
That is hard on motors and might be the cause of the Light pulsing you’re
seeing drake.

Yes, we have a system with AC and DC coupled arrays on an off-grid
system. Having DC coupled capacity is important for reasons given in
other posts.
We used AC coupling due to shade issues, so we could use Enphase
inverters.
In your case, if the house really is going to go on grid, I would t
An all DC side charging is preferred and will have the simplest charging
system. Flex net DC shunts, easy to monitor. Last l heard FM 100 were
pushed out till late in the year

The pole mount does not exist for a few more weeks, so I have time to think
about DC or AC coupling for it only. To clarify, the old roof 1.8 kw array
is functional and has been charging the new blue ions through an old
Outback pre-hub 60A controller(replacing it soon with a new FM60). So I
Its not clear to me if you will actually have a DC side coupled connection
in talking about the pole mount. If so then it does work but if not then
no, the big question is how would you restart the inverter to restart the
SE to start the charging process on the AC side, answer, you can't in most

Hey Kirk,
This is something I've done a few times with success, although I've used an
XW pro instead of the Radian, with OB charge controllers. Having the mix of
DC and AC coupled is ideal, as the solaredge will do the bulk of the
charging, but then charge controllers will do the finish taper charg
Hi Kirk,
I have not done this personally, and this does not pertain to your specific
situation, but related to this subject is the Sol-Ark 15k has a massive AC
coupling capability even with maximum DC connected PV. I really like this
idea for people that want a huge PV array but only need the cont
All,
Anyone out there successfully AC-coupled inverters in an off-grid system?
Advantages vs. pitfalls?
In my case I'm thinking of its practicality with a Solaredge inverter
AC-coupled to an OB Radian inverter. OB firmware makes this pretty easy
now. So effectively the Radian is always operating i
