Description
The line covers the SG25CX-P2, SG30CX-P2, SG36CX-P2 and SG40CX-P2, rated 25, 30, 36 and 40 kVA. The 30 A input suits large-format modules whose string current already exceeds older limits. Input up to 1,100 V means long strings and fewer parallel circuits on the roof. Built-in PID recovery removes the charge modules build up and restores their power at night, and IV string diagnostics finds a failed circuit without a site visit with a tester. The IP66 enclosure with C5 corrosion resistance can stand on an open roof or near the sea. AFCI 2.0 shuts the inverter down on a DC arc. It connects three-phase to the 400 V grid with no site transformer needed.
How to choose
Choose the rating by roof capacity and the permitted connection power, in steps of 25, 30, 36 and 40 kVA. For a larger array, one SG75/110/125CX-P2 at 75–125 kW is simpler than several smaller units. If the site needs backup during outages and a battery, look at the SH15/20/25T hybrid at 15–25 kW with a 100–700 V battery on a 3/N/PE 230/400 V grid. A single-phase house is better served by the SH3.0–6.0RS at 3,000–6,000 W.

FAQ
What is the maximum PV voltage of the SG40CX-P2?
1,100 V with 30 A per input.
Do the SG25/30/36/40CX-P2 inverters have arc protection?
Yes, AFCI 2.0, in an IP66 enclosure with C5 corrosion resistance.
What is the efficiency of the SG36CX-P2?
Maximum efficiency is 98.5%.
What does PID recovery do on the SG30CX-P2?
At night it removes the charge built up in the modules and restores power lost to PID degradation.
How much lighter is the SG25CX-P2 than the previous series?
34% lighter according to the maker, which makes roof and wall mounting easier.
