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.

Expensive, but a well-made slim front pocket wallet
Color: Steven Medium Brown, Size: One Size, Color: Steven Medium Brown, Size: One Size
This is a review for the Fossil “Steven” Front Pocket Bifold Wallet. This wallet measures 4.5 inches x 3.0 inches. It is made with soft-touch leather all around (which feels fantastic), and the build quality is top-notch. It is definitely smaller than a typical wallet, but is still able to hold a good number of cards. I could easily fit about 12 cards into this wallet while still being relatively slim and compact. The wallet is discreet with only a “Fossil” logo that is embossed on the inside. The fabric lining of the cash compartment is treated with an anti-microbial coating. There’s more information about this coating on the manufacturer’s website, but it seems this is to protect against viruses and germs that maybe on cash notes. And while other wallets feature RFID Blocking, this wallet does not claim to do so. This wallet is definitely pricey. And you can easily find other slim wallets for much less. But, I suppose I’m paying for the brand name - and I do like Fossil products. So if you want a brand name wallet that is well-made and slim - this is a good option to consider.

Slim but capable
Color: Steven Medium Brown, Size: One Size
I've had my old wallet for over two decades, it's warren and the edges are starting to fall apart and I thought I'd be proactive and get a new one before it was completely useless. With all the new slim minimalist designs I was intregeed. This is what I found out, at least for my needs. These new elastic card clips, are nice size wise, are not what the are advertised to be. They are small in your pocket but you need another place for the items you don't use everyday. So as far as being slim and efficient they are misleading. Unless you plan ahead you won't have what you need, say health insurance cards oops forgot them cause I don't use them everyday. Ones with cash clips or elastic bands aren't what they are cracked up to be either. To pull out a bill you need to take all the bills out unfold then and then refold the and squeeze the back in the clip, not covenant. Next I tried a bi-fold card holder with a money clip. This solved the having everything I needed even if I didn't use it everyday but still had the cash usability issue which required less folding but still needed to pull all the bills out to use. Plus it wasn't any dinner or smaller then my old wallet. Then I found this wallet, it was pretty much the same as my old one minus one card slot due to the visible ID slot. So in the end this was the perfect wallet for me. Not sure what my old wallet was as the leather is very well worn but I'm guessing it is the same brand. One other thing this wallet is not scan protected which the other slim wallets were. But you can buy cheap sleeves to place on either side to protect against this if your concerned. One benefit of not having this feature is the ability to keep your key card in your wallet and have it work. Again slim but needing multiple place for your items is not efficient, was not a fan of the carabineer I had to also carry while using the slim wallets.

Great wallet
Color: Steven Medium Brown, Size: One Size
Great and very durable wallet. They are slim, fit well in a pocket, and are thin, unless you have lots of CC and money in it.
