STEP 6 PROTOCOL MODIFICATION

In order to connect the battery with an inverter other than the default one, it is necessary to access the SETTING page and select the CAN

protocol needed to communicate with the inverter.

STEP 7

FIRMWARE UPGRADE

To update the firmware to a more recent version, it is necessary to download the latest version of the WeCo BMS software at

www.5K3
