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.
Go green without sacrificing speed.
Pair with solar panels and charge in as fast as 2.3 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.
* With 2 × 220W Portable Solar Panel
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.
Ready for emergencies.
Use as an EPS (emergency power supply) to auto-switch to battery power when the grid goes down. Great for blackouts to keep your essentials running.
Control from anywhere.
