Make it a triple. Expand capacity.
With a capacity of 1kWh to start with, you've got enough energy for your essentials for hours on end. Need even more? Add on the DELTA 2 extra battery to reach 2048Wh, or add on the DELTA Max Extra Battery to hit 3040Wh. Great for home backup or everyday appliances.
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 15 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 2200W thanks to X-Boost technology.
Go green without sacrificing speed.
Pair with solar panels and charge in as fast as 3-6 hours with 1x400W, 2x220W portable solar panels. With its MPPT (Maximum Power Point Tracking) smart algorithm, DELTA 2 can actively detect the voltage and current in real-time to reach the maximum power point with >98% efficiency. 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.
