Remote Control and Monitoring

Equipped with Bluetooth and VE.Can communication interfaces, the controller allows full remote control and monitoring. Using the VictronConnect app, you can easily adjust settings and monitor battery and PV parameters in real time via smartphone or tablet.

Multiple SmartSolar controllers can be daisy-chained with an RJ45 cable, enabling synchronised charge stages and combined data output to compatible GX devices. When connected online, the Victron Remote Management (VRM) portal gives comprehensive visibility and control over your solar setup from anywhere.

There is also an optional plug-in LCD display to provide live data and configuration on the device itself, offering an on-site management option.

Installation and Compatibility

The controller is designed for demanding environments and supports PV arrays up to 250V open circuit voltage with 70A short circuit current. It includes robust terminals compatible with MC4 connectors for secure solar panel connections, and heavy-duty battery terminals for reliable power transfer.

Its IP43-rated electronics and IP22-rated connection area make it suitable for indoor or unconditioned environments where moderate exposure is expected. The unit supports flexible charge algorithms including programmable multi-stage adaptive modes customised to different battery types such as lead-acid and lithium.

Note that while 12, 24, and 48V battery voltages are auto-detected, 36V systems require manual voltage setting for optimal operation.

Can I connect multiple Victron SmartSolar controllers together?

Yes, the VE.Can SmartSolar controllers include CAN bus ports, enabling daisy chaining of multiple units via RJ45 cables. This allows synchronised charge stage operation and consolidated data for GX monitoring devices.

Which battery types are compatible with this controller?

The controller supports a wide range of battery chemistries, including various lead-acid types (AGM, flooded, gel) as well as lithium batteries. Users can select preprogrammed profiles or create custom charging algorithms for optimal battery care.

Does this controller allow remote monitoring?

Yes, it supports Bluetooth remote monitoring via the VictronConnect app on your smart device. Additionally, when paired with a GX device and internet connection, you can utilize Victron’s Remote Management (VRM) portal for extensive monitoring and control online.

Conclusion

The Victron SmartSolar MPPT 250/85-MC4 VE.Can Charge Controller offers reliable, high-efficiency solar charging with advanced remote control and monitoring features. Its ability to work with a variety of battery types, handle powerful solar arrays, and synchronise multiple units makes it an excellent choice for caravans, RVs, off-grid homes, and other mobile or fixed solar setups.
