12KTLX-G3 is a three-phase SOFAR on-grid inverter of 12 kW (maximum apparent power 13.2 kVA), with 2 MPPT, an MPPT range of 140-1000 V and a maximum DC input voltage of 1100 V. The maximum efficiency is 98.5%, the maximum AC output current is 20 A and the protection rating is IP65. The dimensions are 430 x 385 x 182 mm (width x height x depth) and the weight is 18 kg.
12KTLX-G3 is a three-phase SOFAR on-grid inverter with a rated output power of 12 kW (13.2 kVA maximum apparent power), two MPPT trackers, a DC input of up to 1100 V and a maximum efficiency of 98.5%. It has IP65 protection, natural cooling without a fan and weighs 18 kg.
The inverter connects to the three-phase 230/400 V grid (310-480 V, 50/60 Hz) and has two independent MPPT trackers with a DC input of up to 1100 V, which allows longer strings. The maximum input current is 15 A / 30 A per MPPT and the PV short-circuit current is 22.5 A / 45 A. The model has three DC inputs: one on MPPT 1 and two on MPPT 2, with 15 A / 30 A per MPPT.
The protections include DC reverse polarity, anti-islanding, leakage current, ground fault monitoring and PV string fault monitoring, a DC switch and type II surge protection on the DC and AC sides. The inverter offers string-level monitoring and remote firmware upgrade, with natural cooling and no fan; the LCD display and the Bluetooth connection with an app allow commissioning. A stick logger (Wi-Fi, GPRS or Ethernet) can be added as an option for remote monitoring. It operates between -30 and +60 °C, up to 4000 m altitude.
