SolarEdge Three Phase Inverter With Synergy Technology Setup Guide

Key Takeaways

• SolarEdge Synergy inverters (50kW to 120kW) use a modular architecture with a central manager and decentralized secondary units.
• Interconnection of secondary units to the manager is via pre-assembled DC and communication cables.
• Commissioning and physical layout mapping are performed using the SetApp Mobile Commissioning tool via S-Miles Cloud.
• Always switch off the DC battery isolator and wait 5 minutes before working on the system to allow capacitors to discharge.

Setting Up Your SolarEdge Three-Phase Synergy Inverter

This guide outlines the setup and commissioning process for SolarEdge Three-Phase Inverters with Synergy Technology, covering models from 50kW to 120kW. These commercial inverters are designed for grid-parallel energy storage systems. The setup involves interconnecting modular components, configuring the system using a mobile application, and performing essential safety checks.

Understanding the Synergy Architecture

The SolarEdge Synergy inverter system employs a modular design. Commercial inverters split power conversion across decentralized secondary units, which are managed by a central manager. This architecture allows for flexible scaling and efficient power management for commercial and industrial installations.

The system is compatible with standard single-phase and three-phase electrical distribution systems. It also incorporates Built-In Thermal and DC Arc Fault Safety, which includes multi-layer battery safety features such as thermal isolation, aerogel pads, and internal fire extinguishers.

Interconnecting Synergy Components

The physical interconnection of the Synergy system is a critical first step.

1. Mounting: Securely mount the Synergy Manager and all decentralized secondary units according to the manufacturer's guidelines. Ensure adequate ventilation and clearance.
2. Cable Connections: In SolarEdge Synergy commercial setups, secondary units are connected via pre-assembled DC and communication cables to the central manager. These cables simplify the wiring process and ensure correct communication between components.
3. Earthing: Bond the inverter chassis ground to the main installation earthing terminal. This is a protective measure to ensure electrical safety.

Pre-Commissioning with SetApp Mobile

Once the physical installation is complete, the system requires commissioning using the SolarEdge SetApp Mobile Commissioning tool.

1. Download SetApp: Install the SetApp application on your mobile device.
2. Connect to Inverter: Follow the app's instructions to connect your mobile device to the Synergy Manager.
3. System Configuration: Commissioning, module physical layout mapping, and monitoring are configured via S-Miles Cloud using SetApp. This step involves defining the physical layout of the PV modules and optimizers, which is crucial for accurate monitoring and performance.
4. Integrated Diagnostic Test: The Synergy Manager executes automated hardware pre-commissioning self-tests prior to grid connection. This diagnostic test verifies the integrity of the system components and connections, identifying potential issues before full operation.

Safety Checks and Procedures

Safety is paramount when working with high-voltage DC systems.

Always ensure power is isolated before performing any physical work on the inverter or associated wiring. The system is designed to comply with international microgeneration safety and grid protection standards.

Remote Monitoring and Management

After commissioning, the SolarEdge Synergy system supports remote cloud fleet monitoring. This feature allows for remote firmware and configuration management via the VRM cloud portal, enabling ongoing performance tracking and maintenance.

What you can check yourself, and what you cannot

You can perform visual inspections of cable connections, ensure all covers are securely fastened, and monitor system performance through the S-Miles Cloud portal. You can also initiate the pre-commissioning self-tests via SetApp.

However, any internal work on the inverter, such as replacing components or altering internal wiring, must be performed by an accredited installer. Opening the inverter enclosure or attempting to change grid-protection settings yourself can breach connection agreements and compromise safety.

What the published sources do not tell you

While official documentation confirms the modular architecture and the use of SetApp for commissioning, it does not detail specific step-by-step instructions for every screen or menu within the SetApp application. The exact sequence of screens and options can vary with software updates. Furthermore, specific grid connection requirements or export limits, which vary by Distribution Network Operator (grid operator) in Great Britain, are not included. official documentation also mentions "Tigo TS4-A-O optimizers" performing module-level MPPT, but does not elaborate on their specific integration steps within the SolarEdge system, nor does it provide details on how the "Built-In Thermal and DC Arc Fault Safety" specifically functions for the inverter, beyond general battery safety features.
