The FT-152 is a pure sine wave inverter and compact entry-level off-grid power conversion unit. It is designed for small cabins, RVs, and tiny household backup power systems. It is built with a compact toroidal low-frequency transformer for stable low-load operation.

The FT-152 provides clean 220 V AC pure sine wave power with a continuous output of 1.5 kW, supporting a surge power of 4.5 kW to start small inductive loads such as mini refrigerators and LED lighting sets without waveform distortion. The FT-152 is compatible with both 12V and 24V batteries and is fully compatible with gel, AGM, lead-acid and LiFePO4 lithium storage batteries. It has built-in overcharge protection which cuts charging power after a 60-second alarm when the voltage hits safety limits.

Unlike integrated solar inverters, the FT-152 has independent DC PV input ports for connecting an external MPPT solar charge controller, offering users with existing photovoltaic panels flexible solar power expansion. The unit features a 35 A adjustable AC mains charger that can replenish battery energy via the grid or portable generators on cloudy days. It is paired with an ultra-fast UPS transfer time of ≤4 ms to deliver a continuous power supply to small critical loads during grid blackouts.

Five configurable operating modes - mains priority, energy-saving ECO mode, battery priority mode, generator input mode and unattended automatic running mode - adapt to diverse power usage habits. Standard RS485 communication ports enable CAN protocol BMS data interaction with lithium batteries and an optional Wi-Fi module supports real-time system monitoring via iOS and Android mobile apps. The front LCD screen displays real-time battery voltage, load power and fault codes for straightforward on-site inspection.

With an energy transfer efficiency of over 85% and full multi-layer protection against overload, short circuits and reverse wiring, the FT-152 forms a lightweight, cost-effective standalone energy storage system that can be used with small-capacity batteries and external solar controllers.
