Kehua unveiled a 465 kW, 1,600 V string inverter at SNEC 2026 aimed at utility-scale solar, enabling up to 5.6 MW sub-arrays and cutting system costs through longer strings and reduced cabling.
Chinese power electronics specialist Kehua has launched a 465 kW string inverter at SNEC 2026 in Shanghai, targeting utility-scale solar projects in desert and offshore PV applications.
The company presented the product as a next-generation high-power string inverter for large ground-mounted solar plants in harsh environments. It is based on a 1,600 V DC architecture and supports larger sub-array configurations than conventional 1,500 V systems, according to the company.
Kehua said the inverter supports up to 5.6 MW sub-arrays, compared with around 3 MW in many conventional designs. It also features an N+2 long-string configuration, allowing two additional modules per string. The company said the combination of higher voltage, longer strings and larger sub-arrays can reduce DC cable usage, equipment count and overall balance-of-system costs by around CNY 0.037 ($0.0055)/W.
The product targets developers seeking higher power density and lower system costs as large-scale PV plants move toward larger block designs. Kehua said the 1,600 V DC platform can also broaden the MPPT operating range and improve energy yield under low-temperature, high-voltage conditions.
