May 15, 2026 - To meet the rising global need for household reliability and emergency backup power, AOHAI officially launches the FSF-2K1P-BL-PRO, a new 2kW residential off-grid inverter. Designed for critical home loads, this unit is engineered for low-to-medium power household applications.

The inverter covers four typical residential scenarios. It acts as emergency backup power for homes with frequent blackouts to sustain essential appliances. For off-grid remote villages and islands, it establishes standalone PV energy storage systems. Built with superior heat resistance, it performs reliably in sweltering enclosed spaces like attics and hot climate regions. Compatible with lithium battery energy storage systems and supporting BMS communication, it caters to households prioritizing power safety, prolonged battery lifespan and intelligent energy control.

Leveraging in-house technologies and upgraded hardware, the FSF-2K1P-BL-PRO outperforms traditional small-scale inverters. It delivers steady full-power output within the qualified battery voltage range to optimize battery usage. Premium thermal-resistant components, an advanced cooling system and smart temperature algorithms enable continuous full-load operation at up to 40℃. To handle inrush current, the unit provides 5-second double overload capacity, ensuring smooth startup for inductive devices such as refrigerators and water pumps without tripping.

Featuring strong bypass load capability, the inverter maintains stable full-load output above 133.3V, complying with most global grid standards. Its high-current charge and discharge design accelerates recharging and sustains full power at low battery voltage. Equipped with CAN/RS485 and CT interfaces, it enables real-time BMS interaction for intelligent battery protection and longer cycle life, alongside an anti-backflow function to meet grid regulations. An optimized DSP algorithm realizes seamless 4ms grid transfer, offering uninterrupted power for critical loads.

The launch of FSF-2K1P-BL-PRO completes AOHAI’s residential off-grid product portfolio, filling the market demand for lightweight, high-stability home backup power. Moving forward, AOHAI will continue to optimize residential energy storage products, developing high-performance, cost-effective inverters to deliver smarter, safer clean energy solutions for global users.
