This document outlines the process for updating the firmware of Goodwe ES and EM series inverters, providing a step-by-step guide for users to ensure their devices are running the latest software versions. The primary function of this guide is to facilitate a smooth and error-free firmware update, which is crucial for maintaining optimal performance, addressing potential bugs, and introducing new features to the inverters. The update process involves two main stages: updating the main CPU firmware using the EZFlash program and then updating the ARM firmware using the Data Send application.
The Goodwe ES and EM series inverters are designed to manage solar power systems, converting direct current (DC) from solar panels into alternating current (AC) for household or grid use. They often integrate with battery storage systems, allowing for energy independence and optimized power management. The firmware is the embedded software that controls the inverter's operations, including power conversion, grid interaction, battery charging/discharging, and safety protocols. Regular firmware updates are essential to enhance the inverter's efficiency, reliability, and compatibility with evolving grid standards and battery technologies.
The EZFlash program is specifically designed to update the main CPU firmware (both master and slave CPUs) of the Goodwe ES and EM inverters. This part of the firmware is responsible for core operational logic, such as power flow control, maximum power point tracking (MPPT), and communication with other system components. The update ensures that these critical functions are optimized and any known issues are resolved.
The Data Send application is used to update the ARM firmware. The ARM processor typically handles more advanced functionalities, including communication interfaces (like Wi-Fi), data logging, and user interface management. Updating the ARM firmware can improve connectivity, data accuracy, and the overall user experience, especially for newer models or those with advanced monitoring capabilities.
The firmware update process is designed to be user-friendly, although it requires careful attention to detail. Users will need a laptop or PC, a male-to-male USB cable, and the specific EZFlash and Data Send programs, along with the appropriate firmware files. The guide emphasizes the importance of selecting the correct firmware files for the specific inverter model (EM 2.3KW or ES 4.6KW) to prevent compatibility issues.
Before initiating the update, users are instructed to turn off all power sources to the inverter, starting with the grid, then PV, and finally the batteries. This safety measure is critical to prevent damage to the inverter during the update process. However, the inverter can be powered on from either the batteries or the grid once the initial power-down sequence is complete, indicating that a minimal power source is required for the update tools to communicate with the device.
A key usage feature is the requirement to remove the Wi-Fi dongle from the inverter during updates. This suggests that the Wi-Fi module might interfere with the USB communication or that its firmware is updated separately, or perhaps to prevent unexpected network activity during a critical system update. The guide also specifies the location of the USB port for both ES and EM inverters, making it easier for users to identify the connection point. For ES inverters, the USB port is located under a panel marked "Meter," requiring the removal of four screws. For EM inverters, it is conveniently located under the Wi-Fi antenna.
The EZFlash program provides a clear interface with options to "Select File," "Update Master," "Update Slave," "Update Both," and "Connect." The "Update Both" option simplifies the process by allowing simultaneous updates of both master and slave CPUs, which is a common configuration in these inverters. The program also includes a "Log Information" section, which provides real-time feedback on the update status, such as "Welcome to use EzFlash!", "Can not find the HID Device!", and "Check the connection, and click Connect button," guiding the user through potential connection issues.
After selecting the master and slave firmware files, the user clicks "OK" and then "Update Both." The guide states that this process takes approximately 5 minutes and should not be interrupted. The log information will display messages like "Slave cpu update in progress...", "Erase Start!", "Erase End!", "Programming in progress, DO NOT interrupt it!", "Programming complete, start verify!", "Verify complete!", "Slave cpu update successfully!", and "Reset complete!". These messages provide clear status indicators, allowing users to monitor the progress and confirm successful completion.
The Data Send application, while not available in English, follows a similar logic. Users select the firmware file and initiate the update. The interface includes buttons for "选择..." (Select), "发送" (Send), and "停止" (Stop), along with a log area for status messages like "Open USB Fail," indicating a connection problem. The guide emphasizes ensuring "USB Open Success" before proceeding, highlighting the importance of a stable USB connection for this part of the update.
The guide itself serves as a crucial maintenance feature, providing clear instructions for a critical task. By enabling users to update firmware, it empowers them to maintain their inverters' performance and longevity without requiring professional intervention for routine software updates. This reduces downtime and service costs.
The emphasis on reading instructions carefully before updating is a fundamental maintenance practice. It helps prevent errors that could potentially damage the inverter. The warning that "EM inverters may be damaged when updating with PV on" is a critical safety and maintenance note, underscoring the importance of proper power management during the update. This specific warning highlights a known vulnerability or operational constraint that users must adhere to.
The recommendation to download all necessary software and firmware files before traveling to the site is a practical maintenance tip. It anticipates potential internet or computer issues at the installation location, ensuring that the update can proceed smoothly once on-site. Creating a dedicated folder on the desktop for these files further aids in organization and efficient file management.
The instruction to "Please do not Use the EZ flash if the unit has the most current version on" is an important maintenance guideline. It prevents unnecessary updates, which can sometimes introduce unforeseen issues or simply waste time. This suggests that the EZFlash tool might not have a built-in version check, placing the responsibility on the user to verify the current firmware version before proceeding.
The distinction between older and newer ES inverters (shipped after March 2019) regarding the need for EZFlash updates is also a valuable maintenance detail. It indicates that newer models may have a more streamlined update process or come with a sufficiently stable base firmware, requiring only "Data send" updates. This information helps users avoid unnecessary steps and ensures they follow the correct procedure for their specific inverter model.
The provision of a Dropbox link for firmware downloads ensures that users always have access to the latest versions. This centralized repository simplifies the process of finding and acquiring the correct files, which is a key aspect of effective device maintenance. The regular uploading of latest versions to this link ensures that the maintenance information remains current.
Overall, the document provides a comprehensive framework for maintaining Goodwe ES and EM inverters through firmware updates, focusing on user safety, operational efficiency, and long-term device reliability.
