Firmware Update

Firmware updates for high-voltage storage systems are usually carried out via the inverter. If it is not possible to update your high-voltage storage system in this way, a visit from one of our service technicians is required. Information on updating the firmware via the inverter can be found on the inverter manufacturer’s homepage.

In the case of low-voltage storage systems of the 2nd generation (current series), the firmware can be updated by uploading the file to an SD memory card and inserting the card directly at the unit. For the exact procedure, please refer to the manual for your RESU / enblock C product.

Wichtig: The software update may only be performed when instructed by the LG service team and only be performed by trained installation partners. Violation of these instructions will result in warranty termination.
