1.5KW Off Grid Solar Charger Inverter

FTS-1.5KW Low-Frequency Pure Sine Wave Inverter
Engineered by Foshan Top One Power Technology Co., Ltd.
The FTS-1.5KW is a compact yet powerful low-frequency pure sine wave inverter, manufactured by Foshan Top One Power Technology Co., Ltd. – a leading specialist in new energy power conversion solutions, with over 16 years' experience in the industry. As the entry-level model within the widely recognised FTS series, the FTS-1.5KW is designed to deliver reliable, clean power for residential off-grid systems, small offices and remote cabins where grid access is limited or unavailable.

At the core of the FTS-1.5KW is a heavy-duty toroidal transformer that provides exceptional surge capacity. It has a peak power rating of 4.5KW, which is triple its continuous 1.5KW output. This enables the seamless startup of inductive loads, such as refrigerators, freezers, and small pumps. The pure sine wave output maintains total harmonic distortion below 3%, ensuring clean, stable AC power and protecting sensitive electronics, including computers, televisions and medical monitoring devices, from waveform contamination.

The FTS-1.5KW is available in 12 VDC and 24 VDC battery configurations and supports a wide AC input range of 165–275 VAC with automatic 50/60 Hz frequency recognition. An integrated, intelligent, three-stage battery charger (constant current, constant voltage and float) delivers up to 35 A of charging current and is compatible with sealed, AGM, gel, flooded and LiFePO₄ battery chemistries. The automatic transfer switch ensures a seamless transition between battery and AC input, with a rapid switchover time of ≤4 ms that minimises disruption to critical loads during power outages.

The FTS-1.5KW features an intuitive LCD+LED display that provides real-time monitoring of input/output voltage, load percentage and system status. Optional RS485 communication enables remote monitoring via external control panels. The FTS-1.5KW offers comprehensive protection against over-voltage, under-voltage, overload, over-temperature and short circuits.
