45KTLX-G3 is a SOFAR three-phase on-grid inverter rated 45 kW (maximum apparent power 50 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.
45KTLX-G3 is a three-phase on-grid string inverter from SOFAR with a rated power of 45 kW, 4 MPPTs and IP65 protection, designed for small industrial and commercial grid-connected PV systems.
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 45KTLX-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.
