Victron have a state-of-the-art monitoring solution used by the GX products. It can monitor their other system components such as inverter/chargers, solar chargers, shunts, and batteries both local and remote all over the world.
If you have a smaller Victron solution it is nice to know that the same software, Venus OS(VOS), can run on a Raspberry Pi(RPi) instead of the more expensive and versatile GX products.
