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.

The Look I Wanted.
Size: Medium, Color: White
I wear mandarin band collar shirts for semi-formal and/or holiday ballroom dances. This shirt was noted as a blend of 63% cotton, 35% poly and 3% spandex. The shirt is shiny and does not have the cotton feel. It is also so sheer that it shows my V-neck undershirt. It seems more of a women's blouse than man's shirt. The neck and sleeve lengths are good, but the body (Medium) is snug since what I rec'd (but did not want) is 'slim'. The seller's description stated the shirts are 'regular cut', but the package for this shirt said 'slim'. Disappointed in that I think the regular cut Medium would be a good fit. I have purchased this style shirt from several Amazon sellers, and all of them have different size issues, ie too tight, too large, long sleeves, etc, etc. I've returned ALL of them, but I have not decided to keep or return this one. The size charts shown on the sellers' webpage(s) are meaningless, so it becomes a situation of 'buy, try and then return'. I think that is why the webpages call out that these are items that are frequently returned!

Quality at your finger tips
Size: Medium, Color: Burgundy
Excellent choice... Price was "on point", material feels good and durable, size fit great, and most of all the colours were great. Actually purchased several. It's nice to receive a product as it is stated and I did. Recommend very much. Oh and, can be worn at various times of the year. Wash and hung to dry is recommended to preserve quality.

Nice shirt but to shiny for the office
Size: X-Large, Color: Blue
I really like the semi professional, clean, well groomed look of collar-less shirts for my semi formal office. It is appropriate for almost any office occasion. Whether we're getting a visit from the corporate execs., or going out for happy hour...I don't feel over dressed or under dressed. However, for this item: Pros: 1. Excellent classic fit 2. Good stitching and well made Con: It is to shiny! I truly want to purchase every color they have in their lineup, but because of the shimmer, this is probably for someone that wants a night on the town vs a corporate office setting.
