The FT-302 is a pure sine wave inverter and medium-load energy conversion solution. It is tailored for use in large rural households and small off-grid power systems in workshops. It adopts upgraded low-frequency toroidal transformer architecture, enabling it to handle heavier simultaneous load demands than lower-power FT models.

The FT-302 delivers continuous 3 kW of pure sine wave AC power and has a 9 kW 300% surge power buffer. It is capable of starting medium-power inductive equipment, such as household air conditioners and water pumps, without experiencing voltage collapse or waveform distortion. Maintaining triple 12V, 24V and 48V battery voltage compatibility, it supports gel, SLA, AGM, water-based lead-acid and LiFePO4 lithium batteries. Precise overvoltage protection triggers an alarm and stops charging to prevent battery swelling and permanent damage.

Following the split solar design of the FT series, the inverter has dedicated DC PV input terminals for connecting independent external MPPT solar controllers, which gives users greater flexibility to expand solar panel capacity according to local sunlight resources. The built-in 35 A tunable AC charger quickly restores battery capacity via the mains grid or diesel generators during long rainy seasons. The industry-standard ≤ 4 ms UPS transfer time guarantees a zero-power outage for medical devices, office computers, and other priority electrical loads.

Five customisable intelligent operation modes simplify energy management by automatically switching power supply priorities, thereby reducing the frequency of manual operation. A high-definition front LCD screen intuitively displays PV input, battery status, AC output load and system fault alerts, enabling 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 and fault push notifications via mobile apps. With over 85% energy transfer efficiency and full-range electrical safety protection.
