The FTS-152 hybrid solar inverter is the entry-level, all-in-one energy conversion unit in the FTS Series. It has been specially customised for tiny off-grid cabins, small RVs, and household mini backup power systems with limited space for solar installations. The FTS-152 features a built-in 30A MPPT solar charge controller, eliminating the need for external solar regulators and reducing the overall wiring costs of small photovoltaic setups.

It delivers continuous 1.5 kW pure sine wave AC output with 4.5 kW 300% surge power and reliably drives low-power inductive loads, including mini fridges, LED lighting and small televisions, without waveform distortion. The unit supports dual 12V and 24V battery banks and is compatible with gel, AGM, flooded lead-acid and LiFePO4 lithium storage batteries. It features intelligent overcharge protection which triggers a 60-second alarm and cuts the charging current once the voltage exceeds the safety threshold.

The unit accepts a maximum 900 W PV array with a 150 VDC open-circuit voltage limit, making it perfect for small rooftop solar panels in low-budget residential solar projects. A 35 A adjustable built-in AC charger supplements battery charging via the mains grid or portable generators on cloudy days. Paired with an ultra-fast UPS transfer time of ≤4 ms, it delivers an uninterrupted power supply for critical small loads during grid blackouts.

Five configurable operation modes automatically adjust power supply priorities to align with daily low-consumption energy habits. Standard RS485 ports enable CAN protocol BMS communication with lithium batteries and an optional Wi-Fi module supports real-time data viewing via iOS and Android mobile apps. With a front LCD real-time monitoring screen and multi-layer electrical safety protection, the FTS-152 achieves over 85% energy transfer efficiency, forming a compact, cost-effective standalone solar energy storage system for small-scale power demand scenarios.
