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
- Status SetApp page for Commercial inverters: added Sac, I1, I2, I3, V12, V23, V31 measurements as follows:

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

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.
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.
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.
Additional Features
