Hey Michael,
Sorry to hear about your problems.
We have gone through several SMA SI issues that can be very difficult to
narrow down but found most of the time the issues are founded on miss
understanding the affects that different set points have on the over all
system operation.

I have a good for the group. Does anyone know a lag/fastener other than
EJOT that could be used to install PV to a home with metal trusses? To
complicate things the roof is tile and the decking is 1/2" ply.
We do have access to the attic, but in only half the house because of the

It is difficult to quantify but this was pointed out to me years ago by a
long-time off-grid installer, who also lives off grid on Vancouver Island
where weeks of solid cloud isn't unusual. We never tilt to latitude + 10 to
15 for off-grid, as many textbooks recommend.
Latitude works quite well.

This is too funny. I just stumbled upon this phenomenon last week and have
tested it several times with my irradiance meter over the last week or so. I'm
seeing consistently higher irradiance/panel output with panels at a very
shallow to horizontal angle than those set to latitude on cloudy

The paper reference was at the bottom of my original post (1), but a
quick summary of what they recommended was exactly what you mentioned -
Have two axis trackers "go horizontal" during heavy overcast instead of
continuing to track the sun to improve production!

Kirk,
Can you reference your paper on this? So many variables and each
location will be different. Most dual axis
trackers can always be left flat or any angle so that does not make
sense to me.
You have to design for winter offgrid if the location is worth it. Or,

Dave,
My work is focused on remote, off-grid clients. With the XW6048, and XW+6048 it
worked well. Gen 1 on AC1, Gen 2 on AC2. Set the AGS start settings a bit lower
for second gen. Then if any issues with Gen1, Gen 2 would catch it and less
urgent service calls to remote wherever to sort out.
I used to have both an array at a 60° tilt and one at 14° tilt. In the
winter the high tilt array did better on sunny days, and on cloudy days the
shallow array did better. They were different modules and different sized
arrays, so without more analysis than I did, it would be hard to tell which

Any quick answers about how the ITC tax credit deals with loans on a solar

Hi All!
We don't do a lot of pure off-grid systems and I recently ran across
something I wanted to run by folks with more experience in this area:
Optimal array tilt for our very cloudy PNW winters!
My understanding has always been that latitude plus 10-15 degrees was the
best tilt to address

Just spent yesterday debugging a Sol-Ark 15 kW inverter phantom load weirdness.
With Work Mode set at Limited Power To Home it seemed to get a bit schizo,
pulling around 6kW in from the grid on leg L1 and around 13 kW on the other L2
leg, with 7kW of PV added. No house loads were involved. The
On the latest firmware V1.18 both AC1 and AC2 have the same wide
frequency and voltage choices.
This is for watt-node in a self consumption grid mode and also for

Hi Amos,

Try switching to "support" mode and see if the charging current increases.

I know the new SolArk high voltage outdoor batteries have a built in heat
pump (as well as a fire suppression system) Above and beyond that, I
haven't heard of any workable solutions.

Hello wrenches,
We just installed an GS8048a Radian build with Mate 3SL controller (no Optics).
We are having some with charging from the generator, as the generator charging
seems to be limited to about 4500Watts +/- (20amps AC) when charging through
the Radian. It is a Kohler 8.5RES
Dave,
Aren’t AC 1 and AC 2 technically interchangeable? You can set AC priority,
Hz and voltage parameters on both inputs.
Best,

Not getting this Kevin, AC2 has always been the generator input as it
allows wider frequency and voltage settings for drifting gensets.

Physically it is all the same. Software is way more complex. As Dave mentioned,
you have to follow the commissioning process.
AC1 will no longer accept generator input, it’s grid-only now. So if you have a
genset you will need to move that to AC2. This is one of the most irritating
changes
