Manufacturer: Sofar
INDEX: 901.010100205-0
The Sofar Solar 3.3KTL3-G3 is a 3.3 kW single-phase grid inverter with one MPPT, designed for residential PV systems. A maximum input current of 20 A makes it suitable for high-power modules, while the low start-up voltage (70 V) and wide MPPT range (50–550 V) extend the system's operating hours during the day. IP65 protection allows the inverter to be installed outdoors.
