In certain countries, some power grids don't permit sending self-generated energy back to the grid, while others have rules limiting the amount of surplus energy that can be fed into the grid. To navigate these regulations, it's crucial to configure the right feed-in parameters on your inverter.
Setting feed-in parameters in iSolarCloud website:
After logging with your account, as is shown in Fig.1, 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
If there's a need for on-site feed-in limitation, as is shown in Fig.2, the advanced setting interface allows configuration of the following parameters, as illustrated in the figure below.

Common sets:
1. How to set SHT with no feed into the grid:
11-Installed PV Power must be set appropriately to the PV power.
12-Dynamic feed-in limitation is activated
12.1- Maximum feed-in power set to 0.
12.2- Maximum feed-in percentage set to 0.
2. How to set a feed-in limit:
11 -Installed PV power must be set appropriately to the PV power.
12 -Dynamic feed-in limitation is activated.
12.1- Set maximum feed-in power to the relevant value that is to be fed in at maximum.
12.2- Set maximum feed-in percentage to the corresponding percentage of the inverter nominal power that is to be fed in at maximum.
3. How to set a feed-in limit for inverter expansion: If an additional inverter is connected to the battery system, the power limitation is set as follows:
13- Set "rated power of additional power generation systems" to a value corresponding to the rated power of the additional inverter.
11- Installed PV power must be set according to the PV power of the hybrid inverter.
12- Dynamic feed-in limitation is activated.
12.1- Set maximum feed-in power to the relevant value that is to be fed in at maximum.
12.2- Set maximum feed-in percentage to the corresponding percentage of the inverter nominal power that is to be fed in at maximum.
To finalize and confirm these adjustments, remember to apply the settings.
For further information, please download the user manual accordingly:
This manual is intended for professional technicians who are responsible for installation, operation, maintenance and troubleshooting of inverters, and users who need to check inverter parameters. The inverter must only be installed by professional technicians.
