Core technical advantages: First, integrated design, integrated design of photovoltaic modules, inverters, energy storage systems, and elevator drive systems, no need for additional grid transformation, adapting to new buildings and existing elevator renovations; Second, self-generation and self-use, photovoltaic power is preferentially supplied to elevators, excess electricity is stored in energy storage batteries, released during peak electricity consumption, elevator electricity self-sufficiency rate reaches more than 80%, and can be switched to grid power supply in extreme weather; Third, energy efficiency optimization, with the energy feedback system, the electricity generated by elevator downward braking is also stored in the energy storage system, and the comprehensive energy utilization rate reaches more than 95%; Fourth, intelligent management, equipped with an energy management system, real-time monitoring of power generation, electricity consumption, energy storage data, AI algorithm optimizes electricity consumption strategy, maximizes photovoltaic utilization rate; Fifth, scene adaptation, can adapt to various scenes such as residential, commercial, and public buildings. New buildings can realize synchronous design and construction of photovoltaic and elevators, and the renovation cycle of old elevators is no more than 7 days. At present, this technology has been implemented in more than 300 projects nationwide, with a carbon reduction of 3.2 tons per elevator per year, which is one of the core technologies for building carbon neutrality.
