Dana:
The garden variety Cat5 we have been using is rated at 300 volts. Unless your
off-grid system is using 600 volt controllers, standard Cat5 should be code
compliant.
We did source a Belden 600 V Cat5 and used it when we did not really need to.
It was expensive and very hard to terminate.
Jerry:
I thought splices or connections were forbade in condulettes. This sounds
inherently code non-compliant. Do you have information to the contrary?

Hey All'yall.
I am looking for 185' of 600 volt CAT 5 cable for my off grid MidNite Solar
rapid shut down system.
I am not looking for the USE version.
Please contact me off list.
Thankyou!

In the event you or some else installed a Class T fuse and you want to
protect it a little more from cable stress, installing it inside a PVC C
conduit body and cover and fastening the cables to the fuse inside that,
this will protect the fuse from stress and metallic contact and you can p

Also I could never convince the guy to put in a pressure tank and a switch
The reason he got the pump so we didn't have to have a pressure tank

I tangled with one system that had a constant pressure pump
He had moved an off grid system to a location where grid was available And
wanted to use it as a back up
He ended up selling the entire system once I explain to them the thing was
never going to stop running at every possible opportunit
Unless it is a very large offgrid system I agree with Brad. Also if the
electrics fail, are they underground?
I would typically pump to a tank and then drain to a surface pump and
pressure tank/switch at the home.

Constant Pressure pumps are a much better choice off grid. No starting
surge is huge, and the power draw is related to the water flow, so at
low flow rates, the power is only a fraction of full run watts.
Pressure switches and P tanks are archaic. The variable pressure and
the light dimming
Thanks Jay,
I will read the manual later but would you know for sure that is pump soft
starts? The MQ did not.

Dana,
For off grid you may not want to use the constant pressure pumps. They will
run a little bit, a lot of the time to keep the pressure constant. I think
it might be more efficient to use a pressure switch and regular pressure
tank. Anyone with experience in this?

With the low discharge rate of the Aquion battery, it would have to be a
larger bank to handle 6 Sunny Island inverters. To put out the 36kW to
power those inverters at full rate you'd need at least 40 stacks at a good
state of charge to do that. At lower state of charge or if they are the
older ve
Grundfos SCALA2
its the new version of the MQ pump.

The LG RESU series are Lithium Ion 10KWH batteries. I am testing them for
Schneider Electronics solar division with their new product the Conext
Bridge for their battery based XW+ and SW inverter chargers. Outback is
also going to use them with their new inverter/charger "Skybox" Both of

The 2V L16's are 2V one cell. The 6 volt L16's are (3) 2 volt cells but
you should see the SG being way off, right?

That was my point: voltage is not very helpful on the 2 v L16s, as all 3
cells are internally paralleled. With the Flir I was able to see all
the dead cells in the set in seconds.

The FLIR is nice but SG and voltage would have told the same thing, would
it not?
I have excellent experience with the L16 2V cells but will be switching to
the LG RESU 10 very soon for my clients.

I have done this also! I do have respect for Darwin. As long as a school
bus full of kids is not anywhere near the well and it does not sound like
a fault deep in the ground will start a wildfire. That was my reasoning at

What has been the reliability issue with Grundfos? I have not had any
problems with them other than the above ground electronics.
A side question, has anyone found a small (1/2hp) above ground household
pump that is soft start and reasonably priced?

My well driller-well pump guy is offering Sta-Rite pumps manufactured by
Pentair [as in Pentair water filtration they seem to be buying lots of water
related companies].
I am curious as to feedback on these, has anyone used them?
