It is advisable to use appropriate cable connectors recommended by Growatt to maintain optimal performance and minimize the risk of electrical faults.

4. AC Output Connection

Next, connect the AC output terminals of the inverter to the main distribution board or electrical panel of your building. Follow the local electrical code and regulations regarding the sizing and installation of circuit breakers and disconnect switches. Properly tighten all connections to prevent any loose wiring.

5. Grounding

Grounding is a critical step in ensuring the safety and proper functioning of the solar power system. Connect the grounding wire from the inverter to an appropriate grounding point, such as a grounding rod or metal ground plate. It is important to check local electrical codes for specific grounding requirements in your area.

6. Monitoring and Communication

Growatt On-Grid inverters come equipped with monitoring and communication capabilities, allowing you to monitor the performance of your solar power system. Connect the provided communication cables to the designated ports on the inverter and follow the manufacturer's instructions to set up and configure the monitoring system.

7. Testing and Commissioning

Once all the connections are made, it is crucial to test and commission the system before finalizing the installation. Switch on the main power supply and ensure that the inverter powers up without any error messages. Verify that the solar panels are generating electricity and that the inverter is successfully converting it into usable AC power.

8. Final Checks and Maintenance

After installation, perform a final inspection of all connections to ensure they are secure and properly insulated. Regularly check the inverter's display and monitoring system for any error messages or abnormal readings. Additionally, follow Growatt's maintenance guidelines to keep the inverter clean and functioning optimally.


Installing a Growatt On-Grid inverter is a straightforward process that requires careful attention to safety and proper connection. By following the steps outlined in this article and referring to the user manual provided by Growatt, you can successfully install and commission your inverter, allowing you to harness the full potential of your solar power system. Enjoy the benefits of clean and renewable energy while reducing your carbon footprint!
