Huawei At SNEC- Off Grid Solutions, Mytileneos Tie-Up and More

Huawei, always a towering presence at SNEC Shanghai as the largest inverter seller in the world, has marked the 2021 edition with a slew of announcements and launches.

Doing the honors early was Peng Jianhua, President of Site Power Facility, Huawei Digital Power Technologies Co., Ltd. He released the full series of comprehensive offgrid fuel removal power solution iPowerCube to the global audience. Serving as an inclusive power supply in all scenarios, the solutions seek to provide cost-effective, green, and reliable power for domestic and industrial users in off-grid and unreliable grid areas, helping bridge the energy divide.

This provides megawatt-level power supply capability and applies to industrial production scenarios such as mines, factories, and campuses, as well as livelihood scenarios such as large villages, islands, and resorts. Compared with the traditional AC coupling solution, the iPowerCube-P uses the DC coupling architecture, which reduces the number of energy conversion times, improves the efficiency, reduces the investment, and lowers the LCOE. In Cameroon, over 25 MW PV plants and 60 MWh energy storage systems adopt the Huawei off-grid solution, powering 350 remote villages and benefiting about 50,000 households with approximate 300,000 residents.
