516 KWh (500 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 250 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 250 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.

My daughter is SUPER picky about shoes and loves these. They are easy and quick to put on, run true to size, and most important COMFORTABLE. She is outgrowing them and will have to get her the next size up. Highly recommend for picky kids

Great for busy feet
Size: 13 Little Kid, Color: Hot Pink/Multi, Size: 13 Little Kid, Color: Hot Pink/Multi
My five-year-old daughter loves these Skechers slip-ins—and she is not easy on her shoes! You can see in the photo, she’s already put plenty of miles on them. They’ve been through the washing machine at least twice and still look great—the bright colors are a big hit with her and they hold up well in the wash. One of the elastic bands on top did come loose, but I was able to fix it quickly with a dab of superglue. She slips them on and off all by herself, which is perfect as we’re still learning to tie laces. All in all, a great purchase for the price—especially since kids grow so fast and put their shoes through a lot!
