SmartSolar MPPT VE.Can 150/70 MC4

The VE.Can communication protocol from Victron Energy is an advanced interface designed to optimize the management of energy systems, particularly marine and autonomous ones. It enables robust interconnection and precise coordination between different Victron Energy components, especially SmartSolar MPPT solar charge controllers. This interface is essential for complex installations requiring unified energy management.

The ultra-fast MPPT technology of this charge controller significantly improves energy harvesting. It can increase energy production by up to 30 % compared to PWM charge controllers and up to 10 % compared to slower MPPT controllers. This performance is particularly noticeable in cloudy conditions or partial shading, where light intensity changes continuously.

This SmartSolar MPPT charge controller stands out with a maximum conversion efficiency exceeding 98%. This high efficiency is achieved without requiring a cooling fan, which contributes to its reliability and low self-consumption.

The controller features a fully programmable charging algorithm, providing high flexibility. It also includes eight pre-programmed algorithms that can be selected using a rotary switch. This multi-stage adaptive charging algorithm optimizes battery charging based on its type and condition, thereby extending its lifespan.

Yes, this controller has a fully discharged battery recovery function. It can initiate charging even if the battery has been discharged to 0 volts. It can also reconnect to a fully discharged Li-ion battery with an integrated disconnect function.

The controller stores trend data on battery voltage, current and temperature, as well as charge output current, PV voltage and PV current. This data is retained for 46 days, enabling detailed monitoring of system performance.

This charge controller can operate within an extended temperature range from -30 °C to +60 °C. It is capable of delivering its full rated power up to an ambient temperature of 40 °C.

Yes, the VE.Can protocol is specifically designed to optimize the management of marine and autonomous energy systems. The SmartSolar MPPT controllers that integrate it are robust and suited to these demanding environments.

The VE.Can controller can communicate with multiple other Victron Energy devices. It can be connected to a Color Control GX or other GX products for centralized monitoring and control. It can also be connected to a PC or other devices via VE.Direct or VE.Can. For external voltage, temperature, and battery current sensing, it is compatible with the Smart Battery Sense, BMV-712 Smart Battery Monitor, or a SmartShunt via Bluetooth.

The VE.Can interface enables advanced parallel synchronization of multiple charge controllers. It is possible to daisy-chain up to 25 SmartSolar MPPT charge controller units, ensuring all controllers operate in phase, whether during bulk, absorption, or float charging. This feature allows for efficient load distribution and optimizes battery lifespan.

Yes, it is possible to use an external battery sensor with this controller. Thanks to the built-in Bluetooth Smart feature, you can transmit the battery voltage and temperature (and current, in the case of a BMV-712 or SmartShunt) to one or more SmartSolar controllers via a Smart Battery Sense, a BMV-712 Smart Battery Monitor or a SmartShunt.

Yes, this controller is compatible with lithium-ion batteries. It includes a recovery function that allows it to reconnect to a fully discharged Li-ion battery with an integrated disconnect function, ensuring safe and efficient management of this type of battery.

Parallel synchronization is possible with both interfaces, but with different capabilities. The VE.Can interface allows synchronizing up to 25 SmartSolar MPPT charge controller units for coordinated management. In contrast, Bluetooth synchronization is limited to a maximum of 10 units. Therefore, VE.Can offers a more robust solution for large-scale installations.

Yes, the controller can be monitored remotely. Monitoring and control are centralized via a GX device such as the Color Control GX, or remotely via the Victron Remote Management (VRM) portal. Additionally, with built-in Bluetooth Smart, you can configure and monitor the controller using the VictronConnect app on a smartphone or tablet.

The controller can withstand a maximum absolute open-circuit PV voltage of 150 V in the coldest conditions. The maximum start-up and operating voltage is 145 V. It is critical to respect these limits to avoid damaging the controller.

To connect multiple charge controllers in parallel and ensure synchronized charging, you can use the VE.Can interface. Up to 25 units can be chained via VE.Can. Alternatively, up to 10 units can be synchronized via Bluetooth. Connection via VE.Can is recommended for larger systems to ensure optimal coordination of charging phases.

This controller provides several data communication options:

VE.Can: For wired data connection to a Color Control GX, other GX products, or parallel synchronization of multiple units.
VE.Direct: For wired data connection to a Color Control GX, a PC, or other devices.
Bluetooth Smart: Built-in for configuration, monitoring, updating, and wireless synchronization with the VictronConnect app on smartphone or tablet.

The controller has an IP43 protection rating for electronic components, meaning it is protected against solid objects larger than 1 mm and water splashes. The connection area has an IP22 protection rating, indicating protection against solid objects larger than 12.5 mm and dripping water.

Yes, it is possible to add an optional pluggable LCD screen (SmartSolar pluggable LCD display) to the controller. To install it, simply remove the rubber gasket protecting the connector on the front of the controller, then plug in the display.
