SolarEdge SetApp Mobile Commissioning Architecture and Configuration Guide

Key Takeaways

• SolarEdge inverters are commissioned via SetApp (screenless models) or an LCD interface, each with specific firmware requirements.
• Configuration for Alternative Power Source (APS) mode, Modbus TCP, and SunSpec protocols follows distinct menu paths for SetApp and LCD models.
• Multiple inverter installations utilise a Leader, follower configuration over RS485-1, with specific settings applied to the Leader or all units.
• The initial smartphone Wi-Fi commissioning process and automated optimizer barcode scanning details are not documented in published sources.

Understanding SolarEdge Inverter Commissioning with SetApp and LCD Interfaces

SolarEdge inverters are designed for commissioning and configuration through either the SetApp mobile application for screenless models or directly via an integrated LCD interface. This guide outlines the architectural considerations and specific configuration settings for key operational modes and communication protocols, rather than a step-by-step initial setup process, as detailed information on the latter is not universally available across all documentation.

For SetApp (screenless) inverters, a firmware version of 4.8.24 or higher is required. LCD inverters, conversely, necessitate Firmware 3.25xx or higher for compatibility with the described settings. It is important to ensure the inverter's firmware meets these minimum requirements before proceeding with any configuration changes.

Configuring Alternative Power Source (APS) Mode

Alternative Power Source (APS) mode allows SolarEdge inverters to operate in conjunction with an external power source, often in grid-forming or grid-support applications. This mode requires specific hardware and software configurations to function correctly.

Requirements for APS Mode:

• Firmware: SetApp (screenless) inverters require Firmware 4.8.24 or higher. LCD inverters require Firmware 3.25xx or higher.
• Dry-contact: A dry-contact connection is necessary for sensing the grid supply.
• Grid Meter: A SolarEdge grid meter is required for Zero feedback functionality.

APS Mode Configuration Paths:

Frequency Shifting (P(f)) Configuration for APS Mode: Frequency shifting is a critical control mechanism in APS mode, allowing the inverter to adjust its power output based on grid frequency. This helps maintain grid stability or manage power flow.

Enabling Communication Protocols: Modbus TCP and SunSpec

SolarEdge inverters support standard communication protocols such as Modbus TCP and SunSpec for monitoring and control, enabling integration with third-party systems like energy management platforms.

Modbus TCP Configuration:

For effective communication, it is advised to configure the SolarEdge inverter’s IP address to a static IP by disabling DHCP, ensuring that the inverter and any monitoring device are on the same LAN or WiFi network.

SunSpec Configuration:

The Device ID for SunSpec should be set to 126.

Integrating Multiple SolarEdge Inverters

When multiple SolarEdge inverters are installed on a single site, they can be configured to work cooperatively, typically in a Leader, follower arrangement. This setup streamlines control and monitoring.

Multiple Inverter Integration Settings:

In a multi-inverter setup, the Leader inverter manages the dry-relay contact and the GPIO setting for Alternative Power Source configuration. However, Grid Control and Frequency Shifting bandwidth must be set up for all inverters on the site. Each inverter also requires its own unique TCP connection and IP address, with consistent SunSpec settings across all units.

Installation Safety and Electrical Requirements

All work involving solar inverters and electrical systems must be performed by qualified personnel. Before any installation, commissioning, or maintenance, ensure that all relevant safety procedures are followed.

• Isolation: Always isolate all power sources to the inverter, including the PV array (DC), battery bank (if applicable), and AC grid connection, by opening their respective breakers or disconnects.
• Lock-out/Tag-out: Implement a lock-out/tag-out procedure to prevent accidental re-energisation during work.
• Personal Protective Equipment (PPE): Wear appropriate PPE, including insulated gloves, safety glasses, and arc-flash rated clothing, especially when working with high-voltage DC or AC circuits.
• Capacitor Discharge: After isolating power, allow sufficient time for internal capacitors to discharge before touching internal components. Refer to the inverter's specific manual for discharge times.
• Earthing: Ensure all equipment is correctly earthed according to local electrical codes and manufacturer specifications.
• Authorised Service: Opening the inverter enclosure, replacing internal components, or re-pinning connectors should only be performed by authorised service technicians.

What the Published Sources Do Not Tell You

The provided documentation, primarily an integration guide, does not cover several aspects crucial for a comprehensive SolarEdge SetApp fast commissioning guide:

• Core SetApp Commissioning Process: The step-by-step procedure for initial smartphone Wi-Fi commissioning using the SetApp, including how to connect the phone to the inverter's Wi-Fi, initial network setup, and the general commissioning workflow, is not detailed.
• Automated Barcode Scanning Layout Map: There is no mention of automated barcode scanning for layout mapping of optimizers or any related features within SetApp.
• Grid Profile Sync: While grid-related settings like Alternative Power Source mode and frequency shifting are described, the general process or feature for "grid profile sync" as a distinct SetApp function is not documented.
• Specific SolarEdge Inverter Models and Ratings: The document refers to "3phase and 1phase HDwave inverters" but does not provide a detailed list of specific models, their power ratings, or other technical specifications.
• Error/Fault Codes: No specific SolarEdge error or fault codes, their meanings, or troubleshooting steps are provided.
• Fault Modes: No detailed fault modes (symptom/cause) are described.
• Safety Facts: No safety information or guidelines specific to SolarEdge hardware or the commissioning process are included beyond general electrical practice.
• "SolarEdge Password": The document mentions "Enter the inverter’s setup menu using the SolarEdge Password" for LCD inverters but does not specify what this password is or how to obtain or reset it.
• Backend Parameter Change: For frequency shifting with APS mode, the document states, "it is important to contact SolarEdge Support to change a parameter in the backend," but the specific parameter is not disclosed.
• RS485-1 Reconfiguration: After SunSpec setup, the document notes, "you can re-configure RS485-1 for your SolarEdge Grid meter," but the steps for this reconfiguration are not detailed.
