Residential inverters

Small Commercial inverters

Three-phase inverters in the 15–30 kW range, the sweet spot for SMEs, schools, and light industrial. Judged on efficiency ROI, string flexibility for complex commercial roofs, monitoring depth, and grid compliance. Backup matters less; bankability and O&M track record matter more.

7 scored · ≥30 kW

Commercial & Industrial inverters

Multi-string and central inverters from 30 kW and above, covering the C&I segment where decision-makers demand bankable ROI, not brochure specs. Judged on peak and weighted efficiency (every 0.1% is real money at scale), SCADA and SunSpec monitoring integration, serviceability, and the financial depth of the manufacturer behind a decade of warranty obligations. Backup islanding is rarely relevant; uptime and O&M are everything.
