SG75/110/125CX-P2 — grid-tied string inverter, 75–125 kW
Country: China · Model: SG75/110/125CX-P2
The manufacturer grid-tied string inverter rated 75–125 kW AC, with 8 MPPTs at 30 A each on the entry SG75CX-P2. It goes into commercial and industrial PV plants running at 1,000 V DC, where strings are built from 500 W+ modules. The IP66 enclosure with C5 corrosion resistance mounts outdoors, including coastal sites and chemical plants.

Description
The topology is transformerless, which keeps the unit lighter and smaller than a transformer-based design. Maximum efficiency is 98.5% and European efficiency 98.3%, so losses barely rise at partial load. The 30 A per MPPT rating suits high-current 500 W+ modules and lets several strings share one tracker. Its output terminals take aluminum cable up to 240 mm², so copper is not mandatory, and long cable runs come out cheaper. The SG75CX-P2 measures 1,020 × 795 × 360 mm and weighs 82 kg, and it mounts on a wall or a steel frame next to the array. IP66 means dust-tight and protected against powerful water jets, so no separate shelter cabinet is needed. The larger SG110CX-P2 and SG125CX-P2 extend the range up to 125 kW.
How to choose
Pick the model by AC power and the DC/AC ratio of the array. The SG75CX-P2 covers 75 kW, the SG110CX-P2 and SG125CX-P2 cover 110 and 125 kW. For a single 150 kW unit with AFCI 3.0 look at the SG150CX, while small 25–40 kVA roofs are served by the SG25/30/36/40CX-P2. Ground-mount plants at 1,500 V fit the SG320/350HX. If the project includes a battery, you need the SH125CX hybrid inverter with its 129–880 V battery input, since the grid-tied SG75/110/125CX-P2 has no direct battery connection.

FAQ
How many MPPTs does the SG75CX-P2 have and what current per input?
The SG75CX-P2 has 8 MPPTs rated 30 A each, which is enough for strings of 500 W+ modules.
What is the efficiency of the SG75/110/125CX-P2 inverters?
Maximum efficiency is 98.5% and European efficiency 98.3%. The European figure is weighted over several load levels, so it tracks annual yield more closely.
What are the dimensions and weight of the SG75CX-P2?
It measures 1,020 × 795 × 360 mm and weighs 82 kg. The unit mounts on a wall or on a frame by the array.
Can aluminum cable be connected to the SG110CX-P2?
Yes, the AC output terminals take aluminum cable up to 240 mm².
