Key Advanced Features

• PowerAssist Technology: Prevents overload of limited AC sources (shore power or generators) by utilizing the battery to supplement the current during peak demand.
• UL 1741 & CSA C22.2 Compliance: Fully certified for North American safety standards, essential for insurance and inspection compliance in mobile and residential systems.
• Seamless UPS Functionality: In the event of a shore power failure, the inverter takes over in less than 20 milliseconds, keeping sensitive electronics running without interruption.
• Intelligent Load Management: Features two AC outputs; the second output is only live when AC power is available, protecting your battery from high-draw appliances like water heaters.
• Lithium Ready: Advanced 4-stage adaptive charging specifically optimized for LiFePO4 batteries with direct BMS communication via VE.Bus.
