I am looking at a Red Lion, 1/2 HP soft start pump for an off grid
system. Does anyone have experience with Red Lion pumps?

This pump will be used in a cistern.
What is the best soft start submersible to run off of
Hi Drake
What makes you say think it’s a soft start?
3 wire isn’t a soft start. It does have a reduced start load but not soft
start.
I’d go with a grundfos sq.

Wrenches,
We have a customer with older (circa 2008) SMA SB5000US
that seems to have failed. Zonna is not an option, none in stock. You

Greetings All;
I have Fortress Battery installation with a pair of E Vault batteries
set up in a Master/ Slave arrangement. Its been working fine for over a
year, but the customer just had a complete shutdown of the batteries
which left multiple freezers, and refrigerator with rotting food.
When I have had someone lose an SPD (I assume it was on DC buss) there
is often latent damage (shows up later) to many of the devices. In a Hi
Rel mode, it is recommended to replace it all. Most offgrid is not that
critical but try telling that to someone with rotten food.
The freezers and re
The SPD was on one of the PV inputs before it came into the house.
There were two Classics, each fed with its own PV input and SPD. It
actually caused an underground splice to fail (high resistance) which I
replaced the splice and restored full voltage, and both Classics were
working fine. J
I have a buddy in tech support at Fortress.
I asked him and he said that elevated absorb volts above 55.2 could cause this
situation.
And then the power cycle would reboot the BMS.
I am presuming its open loop, and the fact you mentioned that there was more PV
and then the shut down sure migh
High voltage disconnect would do this, is the site monitored

I have both controllers set to the Fortress recommended absorb settings
of 54.4 vdc for 2 hrs. Its always possible that there was voltage over
swing or something. I did check that the voltage on the controllers was
within a0.1 vdc of the battery voltage at the Fortresses. I'm now using
a pair
Is it possible that a load shut off, and then the controllers over shot
the voltage long enough to shut the BMS off? If so, what's the
solution? Lower absorb voltages? I checked voltage calibration between
the various pieces of equipment.

RayI think you are on to something. I have multiple eVault MAX batteries on a Radian and I have had mysterious random shutdowns with high SOC before. Could be they were off grid at the time or had a big load shut off causing a voltage bounce. The batteries are comm’d together but not to the Radian,
Just curious what high SoC is? I set mine for 95% or so and do not
worry about the last few %.
Have not seen this problem but do not use fortress. Should not have shut
downs offgrid except LBCO or lightning.
I really think that an SPD should be on the battery as well as AC in and
out these
High SOC would be 96% or so. One of my sites has five eVault MAX. There is a little bit of SOC to Voltage difference, maybe one of them is going over causing the whole lot to trigger a shutdown. I would like to know the definite shutdown voltage setting. The next time I go there, I’ll bring a lapto
Wrenches,
Earlier post was accidental, incomplete (below). Anyway,
I've since rec'd a response from SMA (Thanks Mike), despite my lack of
details of this proposed change-out he offered some valuable tips.
Yes, I was hoping by splitting this array of 30, Evergreen
