258 KWh (250 KWh) Industrial Battery Backup And Energy Storage Systems (ESS) (277/480Y Three Phase)The industrial battery backup and energy storage system for generator replacement can typically power a 120 KVA 480 VAC load for over 2 hours. Backup time increases as the load drops with minor energy consumption adjustments like selectively running HVAC, turning off all unnecessary lights, and powering down and unplugging all non critical appliances. Need more backup time? Just add another unit. The only limit is the number of circuits available on

The industrial battery backup and energy storage system for generator replacement can typically power a 120 KVA 480 VAC load for over 2 hours. Backup time increases as the load drops with minor energy consumption adjustments like selectively running HVAC, turning off all unnecessary lights, and powering down and unplugging all non-critical appliances. 

Need more backup time? Just add another unit. The only limit is the number of circuits available on your electrical panel. One unit takes up one breaker space.

The system is UL and CE listed, made in the USA (California), and made up of LiFePO4 (lithium iron phosphate) batteries. LiFePO4 batteries are much, much safer than standard lithium batteries and have a 10 year minimum approximate useful life. 

Besides acting as a battery backup system, it also allows for demand charge reduction (lower electric bill), peak shaving (lower electric bill), and integrates with solar panels (micro inverter systems), wind power, or other energy sources.

Runs large
Size: Large, Color: White
Runs much larger than I expected. I am 5’4”& 136 pounds. Usually wear a medium or large in some knit tops. So I need to stitch the side seams in hopes it will fit better. I like the weight and softness of the fabric, but really disappointed in the too large armholes. Unwearable for me until I can sew new side seams.
