When Virtual Power Plant (VPP) mode is enabled, the control and management of the hybrid inverter are externally coordinated by connected devices. In some countries, this feature is a requirement.
Customers can set it through iSolarCloud. A third party can see it through RS485 or WIFI.
New systems and retrofit systems support VPP function.
Requirements:
1) Contact SUNGROW for API permission and account first. Complete API interface debugging with the VPP company and the power retailer. Make sure that the performance and function should meet the requirements. Then the bypass control instructions can be delivered by iSolarCloud API service.
2) If a third-party IoT device is adopted, the Modbus protocol debugging should be completed first.
How to set VPP mode through iSolarCloud website: remote setting
After logging with your account, select on the left bar "Settings", and then inside this tab, select the plant and click on "Advanced Settings". Note that the Initial Grid should have been Already set.

2. Inside Advanced settings, in the "Energy Management Parameters" section:
2.1: Enable the Energy Management Mode as VPP.
2.2: Fill in a time value in "External EMS Heartbeat”.
For example, in the following figure, "External EMS Heartbeat" is set to 20s, which means that the hybrid inverter reads the external dispatching instruction every 20s, and if there is no external dispatching instruction, the default "Self-Consumption" will be restored.

To finalize and confirm these adjustments, remember to apply the settings.
