Growatt - Adjusting inverter output power (inverter output limiting) "Export limit"

Would you like to adjust the output of a Growatt inverter? This can easily be done via the OSS Portal. However, you need an installer account for this.

Follow the steps below:

Adjusting the output of a single inverter

1. Log in to https://oss.growatt.com/.

2. Go to Monitoring & Management → Plant List.

3. Double-click the plant containing the inverter whose settings you want to change.

4. Scroll down to Device List and click the cog icon next to the relevant inverter.

5. Scroll further down to the desired setting and adjust it.

Limiting the power output

You can also choose to limit the inverter's maximum power output. Do this as follows:

1. Follow the same steps as above until you are in the inverter's settings menu.

2. Look for the option Active power control or Power ratio.

3. Set the desired percentage. Take the inverter's maximum output into account and calculate the correct new power.

4. Then enable the Memory setting. This ensures that the adjusted setting is retained, even after switching the inverter off and on again.

5. Save the changes.

Multiple Growatt inverters - ShineSEM/ShineMaster

For an installation with multiple inverters, the export limit is set via the ShineSEM or ShineMaster-X.

The central controller measures and monitors the total power of the installation. It then distributes the required power control across the connected devices.

Do not set the export limit separately via ShinePhone on each inverter in such an installation. This can lead to incorrect control.

Setting peak shaving on the ShineSEM/ShineMaster:

• Log in to https://oss.growatt.com/ with your installer account 
• Navigate to the installation under "Monitoring & Management
• Click on "Plant List"
  • Find the installation by plant name or account 
  • Double-click the plant 
  • Scroll down and select the data logger from the device list. 
  • Then click "System settings" next to the cog icon (see image below) 
• Values for import and export can be set here under 'Feed power parameters' = Export 

This can also be set directly when logging in locally to the ShineMaster X; refer to the manual for this.
