Foreword

This document focuses solely on the parameters for charging and discharging the battery. All other configurations and system settings are the responsibility of the integrator to manage and implement.

Before beginning programming, the integrator must thoroughly understand the associated Power Conversion Equipment (PCE). AERL strongly recommends that the integrator participate in the manufacturer's training or integration course, if available, to achieve optimal proficiency.

The LiFe² 5120S can operate in either Managed (Comms) or Self-Managed (No Comms) mode. This guide includes instructions for configuring the system and details the minimum battery requirements for connecting to specific inverter brands. Please review this guide carefully before proceeding with configuration.

Installers and integrators must consistently perform detailed and precise system designs to ensure optimal performance and reliability. AERL is not responsible for designs that result in underperformance or failure to meet expected standards.

Settings may be updated without prior notice as part of our continuous improvement process. The settings provided are accurate as of their release or publication date.

Minimum battery modules are recommended to ensure that the batteries can fully support the performance of the connected PCE. In Managed communication mode, the PCE will operate within the battery's performance limits, ensuring system stability. In Self-Managed mode, adhering to the recommended minimum battery capacity is crucial to maintain battery performance within warranty conditions.

Ensure that the AERL installation manual is followed and that all environmental, installation, and battery specifications are adhered to.

1. Managed Communication (Comms)

The AERL supports select brands of inverters and chargers (PCEs) using a Managed configuration via a CAN bus cable connection. This setup allows the AERL battery to relay crucial information to the connected PCEs, enabling them to adjust the battery's charge and discharge based on its internal cell temperature and state of charge. Managed Communications help optimize the battery's cell lifespan and ensure accurate State of Charge reporting.

The PCEs referenced in this section of the Integration Guide are compatible with CAN bus communications. Be sure to follow the PCEs' instructions for connecting Managed batteries.

2. Self-Managed Communication (No Comms)

The AERL LiFe² allows connection of PCEs that require manual programming of charge settings to control charge and discharge from the battery, known as Self-Managed (No Comms). The PCE must have the ability to customize its charge settings to suit the battery's requirements.

This section outlines the settings and the minimum battery requirements for popular brands of PCEs. If your selected PCE is not listed here, please get in touch with AERL for further confirmation of settings.
