We recently installed a SunRotor pump and controller in a livestock and ag
watering application. Pretty easy install and seems to be working well.The
factory openings and glands didn't mate up well with the conduit and wire runs
I used, but the aluminum cast case was moderately easy to

Thanks to all of you that offered suggestions. I found what I needed for
this project: Nassau National Cable offered a two wire, 14 AWG CU tray
cable. Attached is the data sheet if anyone is interested.

Another reason as Bradley suggests to avoid all of these problems and
only install a closed loop battery power system. Zero problems since

came out with the AES in 2018 or so. A 25% gain in charge time that
genset users will love by closing the loop. Lot's more also!

Great timely topic. I Have a new installation with 3 eFlex and radian
system. Setting were per Outback and Fortress and we had a series of
mid day hi voltage shut downs when our November sun returned. Luckily
it has Optics and the unattended house is now happy with lowered top
voltages. Ray,
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
this.

Another issue is what charge controller are you using? I know for me with
Outback products I’ve had to switch from an FM 80 to the OB - FM 100 in order
to have a more accurate high-voltage cut out voltage.
The FM 100 has a much more accurate micro processor in it then the FM 60 or 80

To add to Jeff's suggestion of targeting 95%, many Li+ batteries have a
spike in voltage as they reach 100%. We just don't have to worry
anymore about sulfate damage from under charging.

Hi Kris
What voltage do you have your charge settings at?
I recommend that bulk or absorb voltage for lithium iron phosphate not be set
above 56 V - there is no reason for it even though many manufactures suggest
higher settings. In cases where total storage is sized generously enough

Hi Kris,
When the BMS suddenly blocks charge, the voltage will spike up if the
charger can't respond quickly enough.
You may try to decrease charge voltage slightly. This same affect can cook
an alternator in a vehicle as well. Higher end BMS systems can shunt
current to mediate this.
Good
Greetings all,
I have seen an issue on two different systems that I am hoping someone can
shed some light on for me. One was a 48 volt pack of 12 volt Battle Bornes
and the other was a 24 volt pack of SOKs. What happens is when reaching
the end of the bulk charging stage, the battery voltage
