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.

I installed this on an e46 325ix sedan, they only worked, one of them is just a little loose. I don't know how long they last, because every time I open the bonnet, the lever bothers me a little?

Driver side is smaller and every time I open the hood it fall down. I have to bend the lever to open the hood to install it. It look good but I’m not happy with it and I’m scared ti drop it while I’m driving. I have to check on it every where I go to be sure didn’t fall
