Product description

The Victron SmartSolar MPPT 150|35 is an ultra-fast MPPT solar charge controller capable of charging batteries with a voltage of 12/24/36 and 48 V. It features the same advanced MPP tracking of the bigger MPPT RS series, and achieves excellent performance in cloudy weather and partial shading conditions. The SmartSolar MPPT 150|35 is so efficient (over 98% under ideal conditions), that it does not need a cooling fan. There are eight pre-programmed battery charging algorithms built-in, that can be selected with a rotary switch. The SmartSolar MPPT 150|35 has a VE.Direct port for communication with a GX device, and built-in Bluetooth allowing for configuration and monitoring via the VictronConnect app and the Victron Remote Management (VRM) online portal.

Additional specifications and description

At a glance
The SmartSolar MPPT 150|35 is a compact, easy-to-use solar charge controller with an advanced design and rich feature set. It is lightweight, efficient and completely silent.
The unit features an adaptive, multi-stage battery charging algorithm with eight presets optimised for different battery types. It automatically detects the battery pack voltage, and uses feedback from its built-in thermal probe to adjust the charging voltage.
The VE.Direct port is used for data communication, enabling local and remote monitoring and management via a GX device such as the Cerbo GX or other.

What is an MPPT Solar Charge Controller?
A solar charge controller, also known as a solar regulator, is a battery charge regulator connected between the solar array and the battery. By continuously tracking the Maximum Power Point, it can extract the most power possible from the solar arrays and use it to charge the battery. The solar output has to be regulated so the battery is charged correctly and does not get overcharged.

What is the use case?
The SmartSolar MPPT 150|35 solar charge controller is designed for use with small off-grid and grid-connected systems, charging 12,24,36 or 48 V DC battery banks. Thanks to its compact size and wide battery voltage compatibility it is ideal for portable systems in vehicles, as well as off grid equipment such as illumination for a billboard, remote weather stations etc.

Efficient and performant
The SmartSolar MPPT 150|35 charge controller is designed from the ground up with efficiency in mind, reaching a conversion efficiency of over 98%!
As a result the device can be passively cooled with only a radiator and doesn’t need a fan. The SmartSolar MPPT 150|35 also features Victron’s advanced Maximum Power Point detection algorithm that optimises performance in partial shading conditions and cloudy weather. Together these features enable the device to extract the maximum power from the photovoltaic panels, with as little waste as possible.

Design and installation considerations
The Victron SmartSolar MPPT 150|35 features a tough plastic enclosure that guarantees safe operation and protects it from damage. The ingress protection rating for the electronic components is IP43 and the rating for the connection terminals is IP22.
Safety can be further improved with the optional MPPT WireBox – Tr cover for the DC terminals, this accessory is recommended if the device is installed in an area accessible to non-technicians.
The Victron SmartSolar MPPT 150|35 is passively cooled using a radiator on the back of the device, when mounting the controller, please make sure to mount it vertically and leave space for airflow.
The three LEDs on the front indicate the current charging mode or issues with the operation of the device.

Built-in protections
The charge controller has multiple integrated safety features, including PV reverse polarity, output short circuit and over-temperature protection. In addition to the operating temperature, the device monitors the battery voltage and will shut down if the voltage is excessive.

The full technical specifications, sample schematics, wiring diagrams and more, can be found in the technical documentation and manuals provided by the manufacturer, available on this webpage.
