Remote Battery Update Guide for EG4 18KPV

Quick guide from the manual

This guide outlines the procedure for updating the firmware of EG4 PowerPro or EG4 LL V2 batteries remotely via the EG4 monitoring portal. Crucial Warning: Once the update process begins, do not cancel or power off the inverter or battery. Doing so may result in a soft-bricked BMS, which would require a manual RS485 update using a Windows computer to recover.

Preparation and Login

Before beginning the update, ensure you have access to the online portal and that your equipment is correctly configured:

• Log in to www.monitor.eg4electronics.com.
• Confirm that the EG4 PowerPro 280ah or EG4 LL V2 100ah battery is visible in the online portal.
• Verify that you are connected to the correct inverter station.

Configuration

To prepare the system for a remote update, you must configure the Lithium Brand setting:

1. Navigate to the Maintenance tab in the portal.
2. Click Read to load current settings.
3. Locate the Lithium Brand setting and set it to Lithium-1.

Performing the Firmware Update

Follow these steps to upload and initiate the firmware update:

1. Navigate to the Remote Update section under the Maintenance tab.
2. Confirm you are on the correct station.
3. Click Choose File next to the Firmware File field.
4. In the navigation box, locate and select the correct .BIN file (e.g., "EG4 18k to PowerPro.bin").
5. Click Upload File to upload the firmware to the portal.
6. Verify that the correct firmware has been uploaded.
7. Click Update under the Action tab.

Monitoring the Update Process

Once you click Update, a progress bar will appear. Note the following stages:

• Download Phase: The progress bar (0% to 100%) indicates the file is being downloaded to the EG4 18k Inverter. Reaching 100% here does not mean the battery update is complete.
• Programming Phase: After the download shows "Success," the actual battery programming begins. Do not power off the system during this time.
• Inverter Screen: You can monitor the process on the EG4 18k inverter screen, which will display "BMS downloading" and "BMS programming" status bars. The battery will automatically restart once the update is finished.
