The FSI series is highly practical for homeowners seeking mid-range, low-power storage solutions, with the FSI-202 2000W 24V model offering balanced power among the range. With 2000W of stable rated power and a 6000W surge output, it can power refrigerators, water pumps, and everyday kitchen appliances simultaneously, making it ideal for regular family backup power and small off-grid holiday homes.

This model stands out thanks to two features: wide PV compatibility and adjustable AC charging current. It supports a maximum 1400W PV array under a 24V battery system, accommodating larger combinations of solar panels to speed up battery charging on sunny days. The built-in AC charger enables users to adjust the charging current up to 35A, providing flexibility to match different battery capacities and prevent overcharging or slow replenishment.

With an integrated AVR stabiliser, it can stabilise fluctuating grid voltage between 165–275 V AC, protecting sensitive electronics from voltage shocks. Multi-layer safeguards, including overheating, overloading and short-circuit protection, extend the service life of the entire unit. Four customisable operating modes adapt to generator-assisted power, mains backup, or fully off-grid use. This FSI inverter features a robust toroidal transformer structure that secures ≥85% conversion efficiency, and a clear LCD monitor that visualises all operational data. Whether for daily grid backup or independent solar storage, this FSI unit strikes a balance between stable performance and affordable running costs for residential users.
