CAN Bus Keepalive Generator for SunPower M0012 and M0020 batteries

This board that is powered via USBC will generate the needed keepalive and initialization messages so that the SunPower M0012 or M0020 batteries stay awake and can be charged and discharged like a normal battery. This will NOT get you any data from the battery CAN bus. It will NOT enable closed loop communication to your inverter. Picture does not necessarily show exactly what comes, we have changed the case over time.

Please indicate when you order how many batteries you will have in the system so we can load it appropriately with the software.

Included (as pictured):

12-60vdc > USBC power supply

Glass fuse and holder
