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:

  • Zero-Export Limitation
    • SolarEdge inverters are now compliant with UNE217001: 2020-10 and Spain ITC-BT-40 (RD 244/2019) zero export to grid regulations. 

Country Table Updates 

CountryIssue Description
Korea

Added new grid code for Korea (800Vdc).

A SE33.3K inverter with DCD will require a fixed string voltage of
800Vdc to allow a 2-string design with S1200 Power Optimizers.

AustraliaTo avoid installer confusion, the name for ‘Old’ Australia grid codes was changed to ‘Obsolete’. 
France

Existing country code was m odified to Cosphi = 1:

  • France (Cosphi = 1) and France MV (Cosphi = 1)

The following new grid codes for power configuration were created:

  • France (Coshpi = -0.94) and France MV (Cosphi = -0.94)
Czech RepublicAdded new Czech inverter settings in accordance with ‘CEZ Distribuce’ defined thresholds
Japan

Updated display names of grid codes for Japan:

  • Code 26: "Japan 50Hz" => "Japan 1ph 202V L-N  / 3ph 350V L-L 50Hz"
  • Code 27: "Japan 60Hz" => "Japan 1ph 202V L-N  / 3ph 350V L-L 60Hz"
SloveniaCountry code updated to support type A certification 

Austria

Austria

R25 - PT1 time constant tau for Q(U) and P(V) is now available for installer input in the Power Control menus

Greece, Slovenia, Slovenia MV, France

Enabled Grid Protection settings

Vietnam

Modified Vietnam grid code to support requirements of sites > 500kW

Hungary

Updated parameters for Hungarian grid codes

Brazil

Updated parameters for Brazilian grid codes according to the national grid operator (ONS)

Norway

Updated Norwegian grid codes stage 1 frequency thresholds to:

  • 087 – Norway

  • 150 - Norway Delta

Italy

Split Italy country settings into three new settings in order to help installers correctly set frequency and voltage thresholds:

  • Italy 0-21 Low

  • Italy 0-21 High

 

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

Version: 4.19.513

Release Date: August 2023

This release supports the UK PV market only.

With the introduction on May 1, 2023 of the new G100 Issue 2 Amendment 2 for the customer limiting scheme, SolarEdge residential and commercial products including PV inverters, batteries, and Smart Energy devices now fully comply with this latest G100 amendment.

New Features and Enhancements

G100 Introduction

EREC G100 Issue 2 supersedes EREC G100 Issue 1 Amendment 2 “Technical Requirements for Customers Export and Import Limitation Schemes” and became mandatory for sites commissioned after May 1, 2023. G100 Issue 2 requires control of the PV system such that the current flow levels at the grid connection point will remain within pre-configured boundaries. The current boundaries are set by the installers during the commissioning phase, according to the levels that were agreed upon in the Connection Agreement.

At the steady state, the inverter constantly monitors the current flow level at the grid connection point. It manages the production level and site consumption (by controlling the smart devices) to maintain the Import and Export values within the configured boundaries. G100 also defines a set of rules for entering the system into restricted operational modes in cases where the limitations were breached. If the system is operating in one of the restricted modes, installers will be able to set the system back to Normal mode.

G100 System Settings

System default current limits are as follows:

  • On Commercial sites, the Maximal Import Limit  (MIL) is equal to 60A and the Maximum Export Limit (MEL) is equal to 16A
  • Installers will be able to modify these default values using SetApp.

limit export

Operating in Restricted Mode

EREC G100 Issue 2 defines two levels of operation in restricted modes.
The first level (state 3) is caused due to multiple breaches of the limitations for more than 15 seconds or an excursion longer than 1 minute.
The second level (AKA Locked out mode) is caused by multiple entries into state 3.

Setting the system to Normal operation mode

If the system is in Restricted mode, installers can use SetApp to set the system back to Normal mode.

commissioning

Note: In Commercial sites, installers will not be able to set the system back to Normal operational mode within four hours of the start of state 3.

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
  • For ROW (i.e. all regions outside of Europe and North America), the ability to toggle the inverter fixed string voltage between 750V and 850V  is now supported via SetApp for the SE33.3K, SE66.6K and SE100K commercial inverters
    • Enables improved design flexibility with fewer strings, less cables/fuses and reduced BoS costs
    • Relevant for installations connected to the S1200 Commercial Power Optimizer, and only for specific inverter part numbers
    • Read this App Note to learn how to toggle the inverter fixed string voltage
  • For European countries, the FCR-D-Down capability was added for Three Phase Commercial Inverters with SE DSP. Controlled and managed by Grid Services.

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
