Green Ocean's 60kW DC charger design utilizes interleaved PFC topology reducing input current THD to <5%. The 7kW residential wallbox includes WLAN connectivity and integrated RCBO protection. Manufacturing quality control involves thermal imaging during full-load testing and helium leak detection for cooling systems. Swedish winter operation data confirms reliable performance at -30°C using self-regulating heating systems. Our management software enables group power limiting across 20+ stations with 1-second update intervals.
