Features
Massive, expandable capacity. This bundle starts at 18kWh and is fully expandable. Connect up to 5 batteries to one inverter, or up to 15 batteries across 3 inverters, for a total capacity of up to 90kWh. Add storage now or grow your system over time as your needs change.
Whole-home AC output. Connect up to 3 inverters together for 7.2kW, 14.4kW, or 21.6kW of AC output — more than enough to power almost any home. With dual 120V/240V capability, it handles both standard outlets and high-demand split-phase appliances.
Powerful solar charging. The included 400W panels get you started, and the system is built to scale. Each inverter supports a plug-and-play solar input of up to 5,600W, expandable to 16.8kW of solar charge potential across 3 inverters.
Six ways to recharge. Beyond solar and the grid, you can power up using a gas generator or even your EV charging pile. With the industry's fastest charging speeds of 8,800W, you can top up two batteries in only 2 hours.
Uninterrupted, silent backup. The online UPS delivers an uninterrupted power flow that safeguards vulnerable electronics round-the-clock. For low draws under 2,000W, it runs completely silent — so your nights stay undisturbed.
Built to last. Charge and discharge up to 3,500 times and still retain 80% of battery capacity, with LFP batteries lasting as long as 10 years and a 5-year warranty.
