Power pretty much anything.
A 1800W AC output means you can power more than 90% of your home appliances. That's your microwave, fridge, or even coffee maker covered in a blackout. Or, try plugging in up to 13 devices at once for when you're around the table with the family. Unlike other brands, DELTA 2 can prevent overloading from devices up to 2400W thanks to X-Boost technology.

That means a more efficient charge than other brands.
Pick from a range of solar panels to get the speed you need (110W, 160W, 220W, 400W). With that, you've got access to free energy anywhere.
Built to last 6x longer.
Finally… tech that's made to last. Get years of regular use until hitting 80% of its original capacity. That's down to its LiFePO4 battery chemistry giving you 3000+ full charge and drain cycles.
