Frequently Asked Questions
What does X-Boost do?
X-Boost intelligently boosts AC output beyond the station’s rated 2400W up to 3400W for high-draw devices, allowing the DELTA 2 Max to run appliances like electric skillets, space heaters, and power tools that would otherwise exceed the limit.
How fast does it charge from solar?
With dual-port solar input at 1000W total, it can reach a full charge in as fast as 2.3 hours under ideal sun conditions.
How is the DELTA 2 Max different from the regular DELTA 2?
The DELTA 2 Max has 2048Wh vs 1024Wh, supports up to 6144Wh expansion (vs 2048Wh), and has higher solar input (1000W vs 500W) — roughly double the capability at every level.
Can I use this as home backup during a power outage?
Yes — at 2048Wh (6144Wh expanded) it can power a refrigerator for 20-60 hours, charge phones hundreds of times, run a CPAP overnight, and keep lights and routers on through most outages.
