1.What is a Inverter ?
An inverter is a device that converts direct current energy (batteries, storage batteries) into fixed frequency and voltage, or frequency and voltage-regulated alternating current (usually 220V, 50Hz sine wave).
It consists of an inverter bridge, control logic, and a filtering circuit.

2.About Our Product
- High Frequency Inverter: High efficiency and energy saving, with a conversion efficiency of up to 98%, can save more than 20% of energy compared to traditional inverters.
- High Frequency Inverter: Lightweight and small in size, weighing only 1/3 of traditional inverters and occupying only 1/4 of the volume, can greatly save installation space and cost.
- Short dynamic response time and fast control speed, with a response time only 1/10 of traditional inverters, can respond to grid changes more quickly.
- Enhanced control capability and significantly improved process performance, with higher accuracy and stability, can achieve more accurate power output.
