Sunways has made new inverters available for commercial and industrial applications. Sunways inverters STT-15~25KTL-LV three-phase are designed especially for networks 127/220V/60Hz three-phase.
With a power range of 15~25 kW and four MPPTs, the inverters STT-15~25KTL-LV can perform string diagnostics through online scanning analysis IV of the Sunways Monitoring Portal.
Additionally, the input current has been optimized to fully utilize the benefits of high-power modules with 182mm and 210mm cells, resulting in a lower LCOE of system when compared to systems built with conventional 166 mm cell modules.
There are three versions of the new inverters, with outputs of 15 kW, 20 kW and 25 kW. All products have a maximum efficiency of 98,8% and European efficiency of 98,3%. They measure 600 mm x 400 mm x 270 mm and weigh around 42 kg.
The device is equipped with IP66 protection, cooling technology, ability to operate in extreme external conditions such as humidity, high temperatures, high salinity and dust-saturated locations.
Input characteristics
With an operating range of 180 – 550 V (DC) and a limit of 26 A per MPPT, the lowest power inverter is capable of supporting 24 kW, and the highest power can reach 40 kW. The three-phase STT-15~25KTL-LV models have 4 MPPT inputs, with a maximum limit of 40 A and space for two strings per input.
