[RE-wrenches] Is Solark UL 9540 Certified?

[Bill Hennessy]

Hi Lorenzo--Simpliphi's website has a a blurb about their batteries being 9540 listed with Sol-Ark. Here's the link:

Maybe the paperwork is in the mail.
As a side note, we did two Sol-Arks with Simpliphi last year and it works fine. Sol-Ark has recently added a generator test start function to its firmware. The system 15kW generator starts and runs for 20 minutes every Monday morning. The system remains grid-tied, so the genny is getting no load exercise.

 Wrenches,
We have recently had an AHJ reject our Solark 12k system with Simpliphi batteries stating:"Energy storage systems are required to be listed per UL 9540 per NEC 706.5 (See also Annex A in the NEC, under energy storage systems). The Sol-Ark system is not listed and tested per UL 9540 but is only listed per UL 1741. The complete system (ie. batteries, inverter, and any other components associated with the energy storage system) must be listed per UL 9540. Please provide documentation and certification sheets (from a Nationally Recognized Testing Lab (NRTL)) for both the batteries and SolArk inverter to show that all components are tested and certified per UL 9540. If it cannot be shown that the batteries are tested and listed with SolArk inverters per UL 9540, then such system cannot be installed and a different system that is listed and tested per UL 9540 must be chosen for the project.
Have any of you run into this with Solark? Is the plans-checker in the wrong about the entire system needing to meet the standard and not just the batteries? The code language is kind of confusing. I can't find any documentation on Solark's website regarding UL 9540. I know Tesla and Simpliphi have recently put out documentation regarding this.
Thanks in advance for your help.
