New Features and Enhancements

FeatureFeature Description

Region

String Detection

 

With the new string detection feature, SolarEdge installers will benefit from:

  • Improved inverter commissioning through automatic validation of Power Optimizer installations
  • More efficient system troubleshooting, if needed

 

Follow these steps to perform string detection:

Note: Pairing Power Optimizers is now accessible via the SetApp Commissioning main menu > Optimizers.

Pairing Power Optimizers

1. In the Optimizers Pairing window, the user has the option to enter the number of Power Optimizers per inverter unit, to shorten the pairing validation time. Furthermore, if the Perform String Detection box is checked, string detection will automatically take place after the pairing process is complete. Tap Start Pairing to start the process.

Optimizers Pairing

2. The string detection process will commence once pairing has finished and can take up to a few minutes, depending on the number of strings and Power Optimizers). A summary screen is displayed after string detection is complete:

3. Tapping More below each unit column will display the detected strings and their connected Power Optimizers:

Note: If the String Detection process is interrupted at any stage by turning OFF the inverter or disconnecting the AC or DC supply, the DC cables will carry high voltage (up to 120V) until the process times out (up to 20 minutes).

Known Issues and Limitations

Central Commissioning feature

While Follower inverters are being upgraded, SetApp may indicate that the inverter cannot be upgraded. However, this may not actually be the case. Use the inverter’s LED indications to verify that the upgrade is in fact proceeding as normal, as referenced here: https://www.solaredge.com/leds

  • Note: This issue occurs mainly on iOS devices
  • Workaround: You may choose to wait until the Followers' firmware upgrade is complete before continuing with the Central Commissioning process. Otherwise, you can proceed as normal and if needed, repeat the process.

Firmware Version: 4.22.517

Release Date: December 2024

This release supports SetApp-enabled Three Phase Commercial Inverters and Three Phase Commercial Inverters with Synergy Technology.

New Features and Enhancements

FeatureFeature Description

Synergy Unit Pairing

 

Save time onsite with the updated Synergy inverter commissioning process, now enabling successful pairing and production of individual Synergy units instead of the whole inverter. For example:

  • Re-pair failed units only, for higher uptime
  • For O&M: pair only a unit in a specific string without interrupting operation of other units 

For example:
1. In SetApp, press ‘Go to Re-pair units’

In SetApp, press ‘Go to Re-pair units

 2. Select the unit you wish to re-pair and start pairing.
The DC voltage will decrease for the selected unit only
Select the unit you wish to re-pairstart pairingThe DC voltage will decrease for the selected unit only

 3. Pairing will then be completed on the selected unit only, without affecting other units

FRT Mode info added to SetApp

 

By adding the following FRT Mode information to the SetApp FRT Mode screen, installers now have additional clarity regarding FRT Mode functionality for an improved user experience: 

SetApp FRT Mode screen
FRT Mode functionality for an improved user experience

Dynamic Reactive Setting at night

 

To improve inverter grid support at night, reactive power production can now be dynamically adjusted via Modbus control.

 


Known Issues and Limitations

  • Optimizers P_OK and status list is populated after performing a Factory Reset. After the Factory Reset, P_OK increases and the Power Optimizers status list in SetApp is also populated with the previously paired Power Optimizers. 
    • Workaround: After pairing is performed, the correct values will appear

New Features and Enhancements

  • SolarEdge Sense Connect
    • Sense Connect functionality is now supported on SolarEdge Three Phase 16K-17K inverters, protecting the PV Module (DC) side of the system. Power Optimizers continuously monitor the connector temperature on their short input and output cables and inform the inverter of any abnormal temperature increase so it can react accordingly
    • SetApp – Power Optimizer serial number is now displayed on Sense Connect alerts
  • Potential Induced Degradation (PID)
    • The ability to enable PID mitigation remotely is now supported for Three Phase Synergy Technology inverters via the Monitoring Platform. Go to the ‘Remote Settings’ menu in the Monitoring Platform’s ‘Admin’ tab to toggle the inverter’s PID Mitigation settings. Learn more here
  • SetApp Interface Updates
    • SetApp PID Activation menu: users can now differentiate between the built-in SolarEdge PID solution and an external third-party PID device
       SetApp PID Activation menu
    • Status SetApp page for Commercial inverters: added Sac, I1, I2, I3, V12, V23, V31 measurements as follows:

  • Country table: made updates related to CA Rule 21 

 

Known Issues and Limitations

  • Optimizers P_OK and status list is populated after performing a Factory Reset. P_OK increases and the Power Optimizers status list in SetApp is also populated with the previously paired Power Optimizers
    • Workaround: After pairing is performed, the correct values will appear
  • Commercial Three Phase Inverters: when enabled, the inverter’s Active Export limit isn't updated to the SetApp status/site/limit field. However, the Active Export feature continues to function normally as configured
  • Central Settings (Leader, Follower): the Follower P(V) and Q(V) values are set to a different value than the Master
    • Workaround: Perform Central Commissioning to restore the correct values to the Follower inverter

Release Notes

New Features and Enhancements

Firmware upgrades during site visits is now optional for inverters that were already commissioned and not connected to an Energy Meter. 

  • After connecting to the inverter using SetApp, if a new firmware version is available you may decide to delay the upgrade to a later time by tapping Skip Upgrade. 

  • Note: SolarEdge recommends upgrading inverter firmware whenever a new version is released

The SolarEdge Sense Connect feature is now supported on Three Phase Commercial Inverters and Three Phase Inverters with Synergy Technology, with DSP1 1.20.xxxx and DSP2 2.20.xxxx  

  • Sense Connect enhances system safety through early detection and prevention of potential electric arcs at the connector level due to improper connections or possible malfunctions resulting from wear and tear

Known issues and limitations

  • Three Phase Inverters with Synergy Technology (up to 120kW): Resetting the inverter during the Pre-Commissioning stage will shut down the system if the inverter is solar powered and a power bank is not connected

    • Workaround: If a reset is required, reconnect the power bank before resetting
