The FTS-302 hybrid solar inverter is designed for use in large rural households and small off-grid workshop power systems that require the simultaneous operation of multiple medium-power electrical devices. The FTS-302 features a maximum total charging current of 95 A, combining solar MPPT charging and 35 A AC mains charging to rapidly restore battery capacity in periods of insufficient sunlight.

It delivers a continuous 3 kW pure sine wave AC output and has a 9 kW 300% surge power buffer, which is capable of starting household air conditioners and water pumps without causing a voltage collapse or system shutdown. The unit maintains triple compatibility with 12V, 24V and 48V batteries and supports gel, SLA, AGM, flooded lead-acid and LiFePO4 lithium batteries. It also features precise overvoltage protection to prevent battery swelling and permanent thermal damage. The unit supports a PV array of up to 3400W under a 48V battery setup and is therefore ideal for large rooftop solar panel arrays with a high demand for solar self-consumption.

It has built-in optional MPPT modules with a capacity of either 30A or 60A to capture maximum solar energy efficiency. In line with the series' standard 150 VDC PV open-circuit voltage limit, costly external overvoltage protection components for PV strings are avoided. The ≤4 ms UPS-grade transfer time guarantees zero power outage for medical devices, office servers, and other priority loads during grid failures. Five customisable intelligent operation modes reduce the need for daily manual energy management. A high-definition front LCD screen displays PV generation, battery state of charge (SOC), AC load power and system fault codes for rapid on-site troubleshooting.

Standard RS485 ports support CAN BMS communication with lithium battery packs and an optional Wi-Fi module enables 24-hour remote monitoring via mobile apps. With an energy transfer efficiency of over 85% and comprehensive multi-layer safety protection, the FTS-302 serves as a core device for high-speed charging in medium-capacity independent solar energy storage ecosystems.
