Commercial & Industrial inverters — engineering FAQ

Questions our customers ask before placing an order. Sized for engineers, not marketing copy.

Which SG-CX-P2 model for a 100 kW commercial rooftop?

The SG110CX is the natural fit: 110 kW AC output with up to 132 kW DC. Allows up to ~20% DC oversize for bifacial. Three-phase 400V or 800V AC depending on grid spec.

How many PV strings does the SG150CX accept?

Up to 24 strings across 12 MPPTs. Each MPPT accepts 2 parallel strings. Typical 565W bifacial × 24 strings × 27 panels/string = ~365 kWp DC, which is a healthy ~1.4× DC/AC ratio.

What grid codes does the SG-CX-P2 support?

Out-of-box support for IEEE 1547, AS/NZS 4777, VDE-AR-N 4105/4110, EN 50549, IEC 62116, IEC 61727. Custom grid code firmware available for specific country/utility regulations.

Is the SG-CX-P2 outdoor-rated for harsh climates?

Yes — IP66 enclosure, -25°C to +60°C operating range. Conformal-coated PCBs (C5-M corrosion class) for coastal and high-humidity installations. Designed for desert, tropical and high-altitude (≤6000m) climates.

What is the standard warranty?

10 years standard on the unit. Extended to 25 years available via Sungrow extended-warranty package. All units we sell ship with valid Sungrow serial numbers — verifiable on Sungrow's official portal.
