Parallel System Dongle and Configuration Management Guide

Introduction

This guide provides detailed instructions for managing dongles and configuring parallel inverter systems, specifically when integrating two previously separate inverter setups into a master/slave (parallel) configuration at your site. Proper configuration ensures reliable communication and optimal system performance.

Process description

When combining two individual inverter systems into a parallel setup, each inverter must maintain its own communication dongle to enable proper system interaction. This setup forms a master/slave network that synchronizes operation across inverters.

Prerequisites

- Two or more inverters previously operating independently at the installation site.

- Communication dongle for each inverter to allow network connectivity.

- Access to the inverter manual for parallel system setup instructions.

Step-by-step instructions

1. Confirm that you have one communication dongle installed on each inverter at your installation site.

2. Follow the inverter manual’s parallel setup section exactly to configure each inverter into master or slave mode as appropriate.

3. Enable terminal resistors only on the first and last inverter in the parallel chain to ensure proper communication termination and to avoid signal reflections.

4. Verify that all inverters are correctly communicating through their dongles and that the system operates as a unified master/slave network.

Tips and best practices

• Keep one dongle per inverter to maintain reliable communication.
• Refer strictly to the official inverter manual to ensure accurate parallel configuration settings.
• Check all terminal resistor settings carefully before powering on the system to prevent communication errors.
• If communication issues persist, consider consulting with SolaX Power technical support for assistance.

Next steps

After completing the parallel system configuration and dongle installation, monitor the system for consistent operation and communication stability via your monitoring software or cloud platform.

For additional configuration options or troubleshooting, refer to the extended inverter documentation or contact SolaX Power support.

Additional information

Always ensure firmware on each inverter is up to date before configuring parallel settings to guarantee compatibility and optimal performance.

Keep dongle firmware and software updated as recommended by SolaX Power to maintain stable communication links.

Conclusion

Proper management of communication dongles and adherence to the inverter parallel setup guidelines are critical to achieving seamless master/slave operation. Following this guide helps ensure your SolaX Power parallel system operates efficiently and reliably.
