Why inverter technology

To enhance efficiency and performance, electronic control is frequently employed for equipment like air conditioners and electric motors. However, conventional generators may face challenges in operating these appliances smoothly. That’s where our 3.5 kVA generator model excels. Equipped with a PMG module (Power Module Genverter©), it guarantees precise voltage and frequency regulation, ensuring they remain perfectly within the optimal rotating speed range. This ensures uninterrupted operation for all connected devices. Additionally, the PMG generates surge power for our 3.5 kVA generator, enabling it to handle increased inductive loads effectively. With this advanced technology, our generator provides the power needed to run equipment like air conditioners and electric motors, ensuring optimal performance and uninterrupted functionality.
