Expandable Power System
Start with 4kW output and expand up to 12kW to power heavy-duty appliances including 3-ton central air conditioning units and 1 HP water pumps. The 4kWh base capacity scales to 48kWh, providing 2-4 days of whole-home backup power. Support for both 120V and 240V configurations ensures compatibility with standard and high-voltage appliances.
Ultra-Fast Charging Technology
Experience industry-leading 7000W AC charging speeds with X-STREAM technology, dramatically reducing downtime. The dual-PV input supports up to 2600W solar charging, enabling rapid renewable energy harvesting. Multiple charging options include wall outlets, solar panels, gas generators, and EV charging stations.
Advanced Power Protection
The integrated 10ms UPS (Uninterruptible Power Supply) provides seamless power transitions, protecting sensitive electronics like NAS devices, 3D printers, CPAP machines, and security systems. X-BOOST technology extends single-unit capability to 6kW, powering high-demand appliances like washers, dryers, and water heaters without additional units.
