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.

One of the best deals available!
Color: White, Size: 2 Pack
Extremely sturdy, good looking and easy to install. I have a couple of dozen feet of assorted lengths in the kitchen, bedroom, living room and foyer. Holding all sorts of antique clocks, audio equipment and cooking stuff from my flours and assorted cornmeals to cases of powdered “lemonade”.

Okay shelves for the price: Install is a pain
Color: Maple Wood, Size: 3 Pack, Color: Maple Wood, Size: 3 Pack
The shelves themselves are mostly fine, they look as advertised on the wall and the laminate wood is nice. I haven't rigorously tested their weight, but they don't jiggle. I docked one star because it isn't totally flush with the wall (a few mm off) and one of the two screws that keeps the shelf in place wouldn't screw in flush with the board, leaving the sticker cover noticeably loose. I docked the other star because their claim that installation takes less than 5 minutes is entirely false. It took me at least one hour to install one shelf: I had to mark all 8 drywall holes on the wall very accurately and using a level, drill pilot holes (I didn't do this at first and one of the holes was misaligned), drill the full holes (I used a 1/4in bit), hammer in the anchors, screw in the mount (by hand because the mounting pipes blocked my power drill), attach the shelf with the two bottom screws (which took several tries to get close to flush), then clean up the drywall mess. Plus double check everything along the way because I don't want eight 1/4 in misaligned holes in my wall. That's all fine and somewhat expected, but they shouldn't make false claims about the installation ease and time. Any review that says it took them 5 minutes is by an extremely experienced handyman or a liar.

Would buy again and again
Color: Black, Size: 35.4 Inches
These are beautiful! I thought they’d be hard to install, but very straightforward and easy. They are quality and sturdy. I staggered the shelves and they hold a lot. Great value for the quality. I will be buying more for another room in the house.

Made my bathroom look beautiful
Color: White, Size: 15.7 Inches
The mounting and the color were excellent. I hung this in my bathroom and thought it was going to be a hard install for me. The hardware that came with this was very self explanatory. The fit was perfect and the quality was great. I would surely buy this item again in the future
