they have a CEC approved server rack battery that they are now
integrating UL 9540 on their own re-branded Inverter. Cheaper than
Storz Power but the inverter is probably a gro-watt equivalent. So I'm
sticking with Storz Power now so I can utilize UL 9540 on Sol-Arks.<span></span><br>

Hi Chris,<br>
<br>
My only experience thus far is ordering and getting tech support on a
biggish system's worth. 3 Sol Arks on 16<span style="font-style:
italic;"> </span>Storzpower 5.12 KW batteries.<br>
<br>
In working with Everett and his staff I'm very impressed. They are the
first to get UL 9<span style="color: rgb(255, 38, 0);"><span
style="color: rgb(0, 0, 0);">540 on a server rack battery with the
Sol-Ark. They flash the Sol-Ark to synchronize with their batts. I
really like server rack batteries (StorzPower, Signature Solar, Jakiper,
etc.) The 5 KWH increments are nice - easy to rack. Great price -
quality on tear-downs and experience in the field is thus far great.
Same pouch cells many of the big names are using - proven BMSs.<br>
<br>
The only limitation at this point is comm limitations. Everett says
Sol-Arks are presently limited to reading 7 of those type batteries per
inverter. The batteries have a 4 place dip switch arrangement for ID
and thus limited to 16 IDs (14 or 15 in practice depending on the
battery as the Inverter uses a channel).<br>
<br>
I'm solving that on one project I'm doing with Signature Solar EG4s
(open loop on Sunny Islands) by simply having a dedicated laptop running
the battery BMS software monitoring app on a PC. That way I can see
SOC of every battery (and voltage of every cell and do the setting
feedback loop in my brain rather than closed loop - pretty easy to see
what's going on that way by tracking both what ennexOS is telling me
about the Sunny Islands and the BMS's are saying. But that's for open
loop in the Bahamas.<br>
<br>
In CA or anyplace else that cares about UL 9540 (which will soon be
everywhere perhaps) the integrated closed loop is the way to go so
loving that Storz Power stepped up to offer that. <br>
<br>
I'll let you know once I get them installed and up and running.<br>
<br>
Best,<br>
<br>
Jeff<br>
