Adana-based WHS introduced a PV-powered water heating system that operates without an inverter, using 1.6 kW of direct DC solar input with integrated MPPT. The system supports hybrid operation with a 2 kW AC backup, runs at extra-low voltage of less than 50 V, delivers around 3 kWh/day of thermal energy, and heats water to 65–85 C for residential and small commercial use.
