MCU Update Procedure for Inverters
Professional Version - Technical Document
Introduction
This document details the complete procedure for performing a Microcontroller (MCU) update on inverters. This operation is essential to maintain optimal equipment performance and integrate the latest software improvements.
A correctly performed update ensures proper inverter operation and extends its lifespan. It is crucial to follow this procedure step by step to avoid any malfunction.
Safety Warnings
CRITICAL ATTENTION
An interrupted update can render the inverter unusable.
Do not disconnect power from the computer or inverter during the procedure.
Avoid putting the computer to sleep during the update.
Ensure your computer battery is sufficiently charged or the computer is plugged into mains power.
Back up all important data before starting the procedure.
Prerequisites
Required Hardware
A computer with an available USB port
USB to RS232 cable provided by us
RS232 to RJ45 cable provided with the inverter
The inverter to be updated
Update files (MCU and DSP) previously extracted
Required Software
"Remote Panel Reflashtool" software installed
Update files decompressed and ready to use
Initial Configuration
Preliminary Checks
Ensure that the update files have been extracted from their compressed archive
Disable automatic sleep mode on your computer to avoid any interruption
Detailed Procedure
1 Inverter Preparation
Stop certain inverter functions:
Completely disable the inverter output
Stop photovoltaic panel (PV) power supply
Keep battery and grid power active to allow communication
Check inverter status:
Ensure the inverter screen is on and functional
Verify that no critical alarms are active
2 Computer to Inverter Connection
Connect the USB cable to the computer:
Use an available and functional USB port
Wait for the operating system to detect the new device
Identify the assigned COM port:
Open Windows Device Manager
Expand the "Ports (COM & LPT)" section
Note the COM port number assigned to the newly connected device
This number will be needed for the update software configuration
Connect the other end of the cable (RJ45) to the inverter COM port:
Ensure the connection is firm and secure
Verify that the inverter recognizes the connection (usually indicated by a light or screen message)
3 MCU Update
Launch the update software:
Run the "Remote Panel Reflashtool" application
Wait for the main interface to display completely
Software configuration:
Select the previously identified COM port in the software settings
Verify that the communication speed is correctly configured (usually automatic)
Update initiation:
Click the "Update MCU" button in the software interface
Select the previously extracted MCU update file
Confirm your selection to start the process
Update monitoring:
Observe the update progress on the computer screen
Do not touch any equipment during this phase
Ensure the computer does not go to sleep
Typical update duration is 5 to 15 minutes depending on the inverter model
MCU update completion:
Wait for the confirmation message indicating the update is complete
Click "EXIT" in the software to properly close the update session
4 DSP Update (if necessary)
Preparation for DSP update:
Keep the inverter and computer connected
Ensure the inverter is still properly powered
DSP update procedure:
Restart the "Remote Panel Reflashtool" application if it was closed
Follow a similar procedure to the MCU, but select the DSP update file
Follow the on-screen instructions to complete this second update
Post-Update Verification
Version Control
Check in the inverter menu that the new firmware version is properly installed
Confirm that the update date matches the operation you just performed
Functional Test
Progressively reactivate all inverter functions
Verify that the inverter output works correctly
Reactivate photovoltaic panel power supply
Observe operation for several minutes to ensure stability
Common Troubleshooting
Inverter does not detect the connection
Check that the cable is properly connected on both sides
Try another USB port on the computer
Restart the inverter and computer
Update failure
Note the displayed error code
Verify that you are using the correct update files for your inverter model
Contact technical support providing the error code
Computer does not recognize the device
Install or reinstall the necessary drivers
Try another USB cable if available
Check in device manager if the device appears with an exclamation mark
Glossary
MCU
