I have a Sunny Island 6048-US and not sure if the firmware is correct.
Hi David, the first one is just the software release info.
The latest firmware revision is indeed 2.7. The only thing that changes is the CANBus driver.
If you can just send me your BMS serial number we will send you an updated firmware bin file with the Sunny driver installed. Please email it to tech@offgridsoftwaresolutions.com
It can be installed using either the wifi module or the software tool and only takes a few minutes.
Thanks!
