- Key Products/Technologies
- Solar Inverters: The SL-GH Series (1000 ~ 3000KW) represents Korea's first DC 1500V multi-central type solar inverter, offering capacities from 1000kW to 3000kW with a maximum efficiency exceeding 98.2%. The AC LVC Series (250 ~ 500KW) includes inverter products ranging from 250kW to 500kW. For ~100kW class inverters, models like the C-100 (Korea's first wall-mounted type with integrated connection box, DC ground fault detection and protection, IP65 rating, 50kW, 100kW capacities) and the discontinued MultiString Type M10 Series and DC High Voltage Link Only MC Series are available. The T1-11~TB250KW series offers on-grid inverters from 11kW to 250kW with efficiencies of 94~96%. The company also provides SL-B Series and WMS Monitoring Systems for efficient power plant operation and surveillance.Solar Inverters: The SL-GH Series (1000 ~ 3000KW) represents Korea's first DC 1500V multi-central type solar inverter, offering capacities from 1000kW to 3000kW with a maximum efficiency exceeding 98.2%.
