Based on 4-quadrant energy feedback technology, INVT provides an integrated electrical control solution for low-carbon environmentally friendly elevators, achieving energy saving, reduced consumption, and stable operation, while supporting green building and elevator energy efficiency upgrades.
High elevator energy consumption and high operating costs
Braking energy wasted without recovery
Low power factor and poor power grid quality
High machine room temperature leading to premature aging of components
INVT’s low-carbon elevator electrical control system integrates a 4-quadrant energy feedback integrated drive, intelligent variable frequency drive, and IoT module. It enables automatic recovery of braking energy and feedback to the power grid, supports remote monitoring and energy efficiency analysis, features high-protection design and modular architecture, and is suitable for both new installation and modernization scenarios, facilitating energy-saving and intelligent upgrades of elevators.
