Description
The 1,000 V DC class sets the rating for the whole DC side, so modules, cable, connectors and disconnects are chosen to match. AFCI 3.0 detects an electric arc at distances up to 450 m, enough for long DC runs on a big roof where a connector arc is the main fire risk. Global MPPT scanning sweeps the full I-V curve of a string and does not stop at a local peak under partial shade, which the maker puts at +2% yield. Separate trackers per string group limit losses when vents or a parapet shade part of the roof. MPPT count, efficiency and dimensions are available on request.
How to choose
The SG150CX fits when a roof or ground array is built from several 150 kW inverters and string voltage stays within 1,000 V. For a smaller site or a lighter unit, look at the SG75/110/125CX-P2 at 75–125 kW, where the SG75CX-P2 has 8 MPPTs at 30 A and weighs 82 kg. A 25–40 kVA commercial roof suits the SG25/30/36/40CX-P2 with input up to 1,100 V. A 1,500 V ground plant with an 800 V output is built on the SG320/350HX, which uses a different insulation class across the DC side.

FAQ
What DC voltage is the SG150CX rated for?
For 1,000 V DC systems, and modules, cable and switchgear are chosen for that class.
What is the arc detection range of the SG150CX?
AFCI 3.0 detects an arc up to 450 m from the inverter.
What does global MPPT scanning give on the SG150CX?
About +2% yield according to the maker, mostly on strings with partial shading.
Can the SG150CX be used on a ground-mounted PV plant?
Yes, it is rated for both large roofs and ground plants with string voltage up to 1,000 V DC.
