OK, all of the fittings were just fine. After pulling the pump it was
obvious that there was a total failure of the Grundfos SQFlex 3SQF-2 pump
head, both the rotor and the check valve. Water just pours through it in
reverse with no pressure. On the last test in place it would not produce

Let us know what size solar panel works well with the US Pumps D5. I did
not see where there was any data to indicate. It looks like you could just
use the motor from the D5 and leave the old pump head in the water line?

I have a water system with a Grundfos SQFlex SQF3-2 pump. I'm getting water
flow in reverse either through the pump or a leak up to the pump. My
question is if the check valve on the top of the pump is not sealing, will
the progressive cavity pump allow water to flow through the pump in
reverse?

Note that the MPPT disco RS works only with Schneider charge controllers.
With any other charge controllers you'll need to use Fire Raptors.

I used to have both an array at a 60° tilt and one at 14° tilt. In the

Just so you know, AEE Solar still has a bunch of Magnum panels and
controls, no inverters, no support though. At least until they find someone
to take it all. Keep an eye out for other close out stuff too. But, yes
they are still going and working on getting better.

My design for one customer was to have one initiator for the PV and

There are three relays that can be programmed. You can’t get accurate battery

The Radian grid AC in is connected to the utility side of the transfer
switch. You may need a service rated fused disconnect on that line,
probably 60A. Then you can feed the AC out to the generator input on the
transfer switch to power the main house panel. It's best and usually

On some LFP batteries the cell balancing only happens at full charge, so
you do need to get to full every so often. Discover AES is one that needs

The issue as I see it is that the Tigo RSS Transmitter and the APsmart
transmitter are both rated to draw up to 800ma. The 12VDC output of the
Sol-Ark inverters is limited to 100ma. Since some have used this
successfully I suppose that means that either these transmitters don't

The ACLD was long ago discontinued. The Morningstar relay driver would work
fine. I think Magnum limited the size of the grid tie inverter to 90% of
the Magnum inverter max power. So 3960W for a MS4448PAE.

The Schneider RSD switch has a Tigo transmitter, which is no longer SunSpec
compliant. SunSpec devices do NOT work. I know for certain that the APsmart
devices do not work.
Fire Raptors are very robust and might be a good choice for off grid where
reliability is paramount. But they come with 6ft
