Export limit for SUN2000 inverters using FusionSolar app

This document describes the steps to be taken to set the export limit for SUN2000 inverters. 

Prerequisites :

• It is mandatory to connect the Smart Meter to the COM port of the inverter.
• Add the smart meter to the inverter menu via the FusionSolar application (Device Maintenance > Add Device > Select a supported power meter from the list  (  only certain smart meters can be used in the export restriction scenario  ) - you can find the compatibility between inverters and smart meters in the last pages of this document.

Step 1:

Log in using the Fusion Solar application as  Installer  (default password is  00000a  )  >Power Adjustmenttab >Grid-tied point control:

 Step 2: 

Grid-tied point control > Active Power > Control Mode > Select the control mode based on the limit requested by the grid operator:

• Unlimited - The output power of the inverter is not limited. The inverter can export unlimited power to the grid.
• Grid connected with zero power - The output power of the inverter is supplied only to the local load, but not to the grid.
• The inverter provides limited power based on the Maximum grid feed-in power setting for the grid

Closed-loop controller:

• if there is only one SUN2000 in the installation, set the closed-loop controller to  Inverter only .
• if multiple SUN2000s are cascaded, set this parameter to  S-Dongle/Smartlogger .

 Restriction mode: 

• Total power - limits the total input power based on all phases combined, meaning the total production minus the combined consumption.  
• Single-phase Power - will be limited to 1/3 of the configured space limit, which means that the input power is the sum of the output minus the consumption of each phase.
