For families with a medium daily power consumption, the FSI series offers reliable, heavy-duty, off-grid equipment. The FSI-302 3000W 24V is a popular choice within the FSI product range. With a continuous rated power of 3000W and a surge power of 9000W, it can easily support multiple high-power domestic devices operating together, such as washing machines and small air conditioners. It is ideal for suburban homes and remote farm energy storage systems.

Its key advantages are its high solar charging capacity and multi-battery compatibility. The optional 60A MPPT solar charger significantly reduces battery charging time when paired with a maximum PV input of 1400W, enabling the full utilisation of rooftop solar resources. It works seamlessly with gel, SLA, AGM and LiFePO4 batteries and has a tailored DC charge voltage for 24 V battery packs to prevent battery degradation caused by improper charging.

The 4 ms UPS provides a seamless transfer, guaranteeing zero downtime for vital loads during power outages. Meanwhile, the built-in AVR stabiliser compensates for unstable mains voltage in rural areas. Four switchable operating modes allow users to prioritise solar energy in order to reduce grid electricity expenditure. Full multi-layer protection automatically cuts power in the event of abnormal conditions such as overvoltage and overheating, thereby avoiding hardware damage. This FSI inverter is constructed with a toroidal transformer to keep energy loss low, with over 85% transfer efficiency. The real-time LCD monitoring panel simplifies routine inspections, making this FSI device a reliable long-term power backup solution for medium-sized residential properties.
