Transformer Station
JUPT-11000K/7000K/3000K-HD1
The SIMO Energy Smart Transformer Station is a highly integrated, containerized renewable energy solution engineered for West African solar deployment in 3MW, 7MW, and 11MW configurations. Pre-wired and pre-tested for rapid installation in remote Sahel locations and ECOWAS microgrids, this containerized system combines power conversion, protection, and intelligent controls to support rural electrification and off-grid energy independence across Mauritania and West Africa. The SF6-free design meets environmental standards while delivering reliable performance in high-temperature, dusty conditions typical of the region's energy access infrastructure.
