Description
Use the EG4 Battery Firmware Adapter to update EG4’s batteries without internet access. The Adapter receives the firmware from a computer and uploads it to the battery. Beyond the initial firmware download, no internet connection is necessary to update the batteries, and no additional software is involved in the updating process.
All cables needed for the computer connection and battery connection are provided with the Battery Firmware Adapter.
The Adapter connects to and updates one battery at a time, and that battery must not be connected to other batteries or any inverters with either power or communication cables. The Adapter stores the firmware update files so they can be used to update other batteries as needed.
The firmware update may use multiple files. Each update takes about 40 seconds, and upon finishing, the Success or FAULT light indicates the update status.
Firmware updates for multiple battery models will disrupt the update, so remember to remove all old firmware updates from the Adapter and add the correct update to the Adapter before using it for a different battery model.
This Adapter is compatible with only the following EG4 battery models:
