Sungrow 110CX Premium Multi MPPT String Inverter for 1000 VDC System, SG110CX

The Sungrow SG110CX Premium is a 110kVA three-phase grid-tie string inverter for 1000Vdc systems, built for large commercial rooftops and utility-scale ground mount. Nine independent MPPTs — exceptional at this power class — each take two strings, allowing a single unit to serve arrays broken across many roof orientations, shading conditions and module types without compromising any of them. The 200–1000V tracking window and 26A per MPPT input suit high-current bifacial and large-format modules. Max efficiency reaches 98.7% with 98.5% European efficiency, among the highest available. A fuse-free design with smart string current monitoring removes the most common maintenance item on large string inverters, and DC 2-in-1 connection reduces combiner hardware and cabling. Compatibility with both aluminium and copper AC cable cuts material cost on long runs. The Q at night function provides reactive power support after dark, which some grid codes now require. Built-in PID recovery reverses potential-induced degradation overnight, and Smart IV Curve diagnosis identifies underperforming strings remotely without a site visit. Touch-free commissioning and remote firmware upgrades keep O&M costs down across large fleets. Protection includes an arc fault circuit interrupter, DC Type I+II and AC Type II surge protection, and an IP66 enclosure with C5 anti-corrosion rating for coastal and industrial sites. Smart forced air cooling supports operation from -30°C to +60°C and altitudes to 4000m.
