[RE-wrenches] Storz Power Batteries

[Jeff Clearwater]

Hi Chris,

My only experience thus far is ordering and getting tech support on a 
biggish system's worth.  3 Sol Arks on 16Storzpower 5.12 KW batteries.

In working with Everett and his staff I'm very impressed.  They are the 
first to get UL 9540 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.

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).

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.

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.

I'll let you know once I get them installed and up and running.

Best,

Jeff
