1,144 KWh (1 MWh) 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 500 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 500 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 small. Order up a size.
Color: Black (001)/Jet Gray, Size: Small
I have small hands so I ordered a small. I even measured my hands to make sure. I couldn't even get the gloves on. They are cute though. They don't seem great for the snow, but I couldn't get them on to even try them out.

great cold weather wardrobe addition!
Color: (110) Summit White / Summit White / Khaki Base, Size: 1 Count (Pack of 1)
So glad I got this. Got tired of trying to manage hats and ponytails in the Northeastern winter! Super well-made, very warm and soft, and so cute!!! I'm a sucker for a beige cable anything. sometimes I stick it around my neck too when I'm not feeling-scarf-y, and while it's not full coverage, I'm glad to have it.

Perfect everyday bag for men
Size: One Size Fits Most, Color: (025) Castlerock / Black / Black
It’s lightweight, attractive, and the perfect size for carrying the amount of things you want throughout the day. Can be casual or carried into a fine restaurant. The strap is long enough to wear cross body on a large man. Also, they provide a loop that allows you to fold up the strap and turn it into a short handled bag. Great price for the quality and usefulness.
