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.

Goodbye Ink Cartridges
I’ve used cartridge printers for years, and the EcoTank system is honestly the biggest selling point here. Filling the tanks was much easier than I expected thanks to the keyed bottles, and I didn’t make a mess during setup. Print quality is sharp for everyday documents, and color prints come out vibrant enough for school projects, photos, and crafts. The scanner works well, the wireless setup was straightforward, and being able to print directly from a phone is convenient. I also appreciate not having to constantly wonder if I’m about to run out of ink after a few dozen pages. The printer itself is fairly compact for an all-in-one unit and fits nicely on a desk. While it isn’t the fastest printer on the market, the long-term savings on ink and the hassle-free refill system make it a solid choice for a home office, students, or a family that prints regularly.

My Go-To Sublimation Paper — Flawless Results Every Time
Size: 8.5"x11", Size: 8.5"x11"
This is hands down the best sublimation paper I’ve used and the only one I continue to buy. I get a perfect transfer every single time—no fracturing, no fading, and no uneven results. The paper dries fast, which makes my workflow so much smoother, especially when I’m producing items in batches. I use this regularly to make air fresheners and tote bags for my small business, and the color payoff is always vibrant and crisp. The transfer rate is excellent, and it works beautifully on light-colored, high-quality polyester and other sublimation-ready surfaces. If you’re a small business owner or crafter who values consistency, quality, and ease of use, this paper is absolutely worth it. I highly recommend it and will continue to repurchase.

Best Sublimation Paper
Size: 8.5"x11"
I’ve been using A-Sub paper for my sublimation projects, and it is easily one of the best. The ink dries almost instantly once printed, so I don’t have to worry about smudging the design or getting those annoying "pizza wheel" marks from the printer rollers. The paper itself feels substantial and doesn't tear or curl easily. One of the biggest wins for me is that it never jams; it feeds through perfectly every time, saving me the frustration of wasting expensive ink and paper. When I go to press my designs, the ink releases almost completely, leaving very little behind on the paper and putting all that color onto the project. The final results look super professional, with colors that are vibrant and sharp rather than looking faded or dull. It has worked perfectly for everything I’ve tried so far, and if you want a reliable paper that gives you consistent, high-quality results, this is definitely the one to get.
