The manual is intended to instruct qualified operators on the proper use and maintenance of the inverters.
Before grid-connection, verify to make sure the grid voltage and frequency meet the requirements of the inverter. Contact the local utility grid company with any connectivity issues.
When the electrical equipment cannot consume all the generated power and surplus power feeds back into the grid, the inverter can monitor the grid-connected power data in real-time via a smart meter
The inverter needs to go to the site for power-off and transmission operations before and after the initial grid connection and maintenance. Standardized and correct operation can not only
