­ Braille Energy Systems Inc. announced that its initial suite of energy storage system (ESS) products is moving from the development phase into the commercialization stage. A key element of market launch is product certification to UL9540 standard; this commercialization step will commence in the coming weeks with an RFQ issued to several NRTL (Nationally Recognized Testing Laboratory) accredited agencies for the certification project for BESI ESS products.
