Megatank products are household emergency all-in-one energy storage power cabinets with 5 kilowatt-hours of electricity to 20 kilowatt-hours of electricity. The products are sold well in Africa, Europe and other regions. In the early stage of the cooperation between Smart Technology and GT Powertank, in order to solve the electrical connection issues with the all-in-one home unit cabinet, they promptly solved the overall wiring harness solution for Megatank and became the main partner.
