The FTS-202 hybrid solar inverter is a off-grid rural homes and retail shops requiring emergency backup power and flexible solar expansion. The FTS-202 stands out thanks to its selectable 30A or 60A built-in MPPT solar controllers, which allow users to upgrade the solar charging capacity without having to replace the main inverter body when expanding the PV panels at a later date.

It provides a steady 2 kW of continuous pure sine wave AC power and has a 6 kW surge power buffer, enabling multiple daily appliances such as small washing machines, fans and desktop computers to be operated simultaneously without any voltage fluctuation. The inverter supports triple 12V, 24V and 48V battery voltage systems, covering all mainstream lead-acid and lithium storage batteries.

Its multi-stage intelligent charging logic adjusts the DC charging voltage to extend battery cycle life. The maximum supported PV power is 1700 W under a 24 V battery configuration, meeting the requirements of medium-scale rooftop solar installations, and the 150 V DC PV open-circuit limit prevents overvoltage damage to the internal circuits. The built-in AVR (automatic voltage regulator) locks the battery-mode AC output within a ±3% tolerance range to protect sensitive electronic equipment. The ≤4 ms seamless transfer switch enables instant switching of power between the utility grid, generator, and battery storage.

Five pre-programmed operating modes simplify energy management by automatically prioritising solar power to reduce grid electricity consumption. RS485 communication ports facilitate two-way data exchange with lithium battery BMS modules and an optional Wi-Fi module enables remote parameter adjustment and sends fault notifications via mobile applications. With ≥85% conversion efficiency, as well as full-range overload, short-circuit and overheating protection, the FTS-202 creates a flexible, upgradeable, multi-energy complementary solar power system for medium-sized household power consumption scenarios.
