40KTLX-G3 is a SOFAR three-phase on-grid inverter rated 40 kW (maximum apparent power 44 kVA), with 4 MPPTs, a 180-1000 V MPPT range and a maximum efficiency of 98.8%. It has IP65 protection, RS485 and Wi-Fi communication, an LCD with Bluetooth and app access, and weighs 37 kg. It includes AFCI for arc fault detection.
40KTLX-G3 is a three-phase on-grid string inverter from SOFAR with a rated power of 40 kW, 4 MPPTs and IP65 protection, designed for small industrial and commercial grid-connected PV systems. The AFCI version includes arc fault detection.
The inverter has 8 DC inputs (2 per MPPT), a maximum input current of 40 A per MPPT and accepts DC overload of up to 150%. On the AC side it tolerates a prolonged 110% overload. It works with PV modules of 500 Wp and above, starts at a low voltage (200 V) and offers I-V curve scanning.
Protections include DC reverse polarity, anti-islanding, leakage current, ground fault, PV string fault monitoring, a DC switch and type II surge protection on DC and AC. The 40KTLX-G3 is wall mounted with the supplied bracket, and at 37 kg it takes at least two people to move. Operating temperature is -30 ... 60 °C with air cooling.
The AFCI function developed by SOFAR identifies the arc signal in the circuit, gives an early warning when an arc fault or short circuit occurs and disconnects the inverter before it can cause a fire.
