Setting Export Limitation Parameters

Scenario 1: Smart Dongle Networking Scenario

Prerequisites

You have logged in to the app as installer. The initial password is 00000a. Use the initial password upon first power-on and change it immediately after login. To ensure account security, change the password periodically and keep the new password in mind. Not changing the initial password may cause password disclosure. A password left unchanged for a long period of time may be stolen or cracked. If a password is lost, devices cannot be accessed. In these cases, the user is liable for any loss caused to the PV plant.

Procedure

1. Set export limitation parameters.

   Table C-1 Control mode

   Parameter			Description
   Unlimited	N/A	-	If this parameter is set to Unlimited, the inverter output power is not limited. The inverter can export its rated power to the power grid.
   Grid connected with zero power	Closed-loop controller	SDongle/SmartLogger Inverter	Set this parameter to SDongle/SmartLogger when the SmartLogger1000A is connected. If multiple inverters are cascaded, set this parameter to SDongle/SmartLogger. If there is only one inverter, set this parameter to Inverter.
   	Limitation mode	Total power Single-phase power	If this parameter is set to Total power, it indicates that no backfeeding occurs for the three phases. If this parameter is set to Single-phase power, it indicates that no backfeeding occurs for the phase with the maximum power.
   	Power lowering adjustment period	-	Specifies the shortest interval for a single anti-backfeeding adjustment.
   	Maximum protection time	-	Specifies the time for detecting meter data. If the Dongle does not detect any meter data within the preset time, the Dongle delivers the preset value of the Active power output limit for fail-safe to the inverter for protection.
   	Power raising threshold	-	Specifies the threshold for raising the inverter output power.
   	Communication disconnection fail-safe	Disable Enable	In the inverter anti-backfeeding scenario, if this parameter is set to Enable, the inverter will derate according to the active power derating percentage when the communication between the inverter and the Dongle is disconnected for a period longer than Communication disconnection detection time.
   	Communication disconnection detection time	-	Specifies the time for determining the communication disconnection between the solar inverter and the Dongle.
   	Active power output limit for fail-safe	-	Specifies the derating value of the inverter active power by percentage. If the Dongle does not detect any meter data or the communication between the Dongle and the inverter is disconnected, the Dongle delivers the derating value of the inverter active power by percentage.
   Power-limited grid connected (kW)	Closed-loop controller	SDongle/SmartLogger Inverter	Set this parameter to SDongle/SmartLogger when the SmartLogger1000A is connected. If multiple inverters are cascaded, set this parameter to SDongle/SmartLogger. If there is only one inverter, set this parameter to Inverter.
   	Limitation mode	Total power Single-phase power	If this parameter is set to Total power, it indicates that no backfeeding occurs for the three phases. If this parameter is set to Single-phase power, it indicates that no backfeeding occurs for the phase with the maximum power.
   	PV plant capacity	-	Specifies the total maximum active power in the inverter cascading scenario.
   	Maximum grid feed-in power (kW)	-	Specifies the maximum active power transmitted from the grid-tied point to the power grid.
   	Power lowering adjustment period	-	Specifies the shortest interval for a single anti-backfeeding adjustment.
   	Maximum protection time	-	Specifies the time for detecting meter data. If the Dongle does not detect any meter data within the preset time, the Dongle delivers the preset value of the Active power output limit for fail-safe to the inverter for protection.
   	Power raising threshold	-	Specifies the threshold for raising the inverter output power.
   	Communication disconnection fail-safe	Disable Enable	In the inverter anti-backfeeding scenario, if this parameter is set to Enable, the inverter will derate according to the active power derating percentage when the communication between the inverter and the Dongle is disconnected for a period longer than Communication disconnection detection time.
   	Communication disconnection detection time	-	Specifies the time for determining the communication disconnection between the solar inverter and the Dongle.
   	Active power output limit for fail-safe	-	Specifies the derating value of the inverter active power by percentage. If the Dongle does not detect any meter data or the communication between the Dongle and the inverter is disconnected, the Dongle delivers the derating value of the inverter active power by percentage.
   Power-limited grid connected (%)	Closed-loop controller	SDongle/SmartLogger Inverter	Set this parameter to SDongle/SmartLogger when the SmartLogger1000A is connected. If multiple inverters are cascaded, set this parameter to SDongle/SmartLogger. If there is only one inverter, set this parameter to Inverter.
   	Limitation mode	Total power Single-phase power	If this parameter is set to Total power, it indicates that no backfeeding occurs for the three phases. If this parameter is set to Single-phase power, it indicates that no backfeeding occurs for the phase with the maximum power.
   	PV plant capacity	-	Specifies the total maximum active power in the inverter cascading scenario.
   	Maximum grid feed-in power (%)	-	Specifies the percentage of the maximum active power of the grid-tied point to the PV plant capacity.
   	Power lowering adjustment period	-	Specifies the shortest interval for a single anti-backfeeding adjustment.
   	Maximum protection time	-	Specifies the time for detecting meter data. If the Dongle does not detect any meter data within the preset time, the Dongle delivers the preset value of the Active power output limit for fail-safe to the inverter for protection.
   	Power raising threshold	-	Specifies the threshold for raising the inverter output power.
   	Communication disconnection fail-safe	Disable Enable	In the inverter anti-backfeeding scenario, if this parameter is set to Enable, the inverter will derate according to the active power derating percentage when the communication between the inverter and the Dongle is disconnected for a period longer than Communication disconnection detection time.
   	Communication disconnection detection time	-	Specifies the time for determining the communication disconnection between the solar inverter and the Dongle.
   	Active power output limit for fail-safe	-	Specifies the derating value of the inverter active power by percentage. If the Dongle does not detect any meter data or the communication between the Dongle and the inverter is disconnected, the Dongle delivers the derating value of the inverter active power by percentage.
