More info


Charge current up to 35A and PV voltage up to 150V

The SmartSolar MPPT 150/35 charge controller is able to charge a lower nominal-voltage battery from a higher nominal voltage PV array. The controller will automatically adjust to a 12V, 24V or a 48V nominal battery voltage.

Ultra-fast Maximum Power Point Tracking (MPPT)

Especially in case of a clouded sky, when light intensity is changing continuously, an ultra fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.

Advanced Maximum Power Point Detection in case of partial shading conditions

If partial shading occurs, two or more maximum power points may be present on the power-voltage curve. Conventional MPPTs tend to lock to a local MPP, which may not be the optimum MPP. The innovative SmartSolar algorithm will always maximize energy harvest by locking to the optimum MPP.

Outstanding conversion efficiency

No cooling fan. Maximum efficiency exceeds 98%. Full output current up to 40°C (104°F).

Extensive electronic protection

Over-temperature protection and power derating when temperature is high. PV short circuit and PV reverse polarity protection. PV reverse current protection.

Internal temperature sensor

Compensates absorption and float charge voltages for temperature.

Automatic battery voltage recognition

The controller will automatically adjust itself to a 12V, 24V or a 48V system one time only. If a different system voltage is required at a later stage, it must be changed manually, for example with the Bluetooth app.

Flexible charge algorithm

Fully programmable charge algorithm, and eight preprogrammed algorithms, selectable with a rotary switch.

Adaptive three step charging

The SmartSolar MPPT Charge Controller is configured for a three step charging process: Bulk – Absorption – Float.

During this stage the controller delivers as much charge current
as possible to rapidly recharge the batteries.

When the battery voltage reaches the absorption voltage setting, the controller switches to constant voltage mode. When only shallow discharges occur the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge the absorption time is automatically increased to make sure that the battery is completely recharged. Additionally, the absorption period is also ended when the charge current decreases to less than 2A.

During this stage, float voltage is applied to the battery to maintain it in a fully charged state. When the battery voltage drops below float voltage during at least 1 minute a new charge cycle will be triggered.

Remote on-off

The MPPT 150/35 can be controlled remotely by a VE.Direct non inverting remote on-off cable (ASS030550300). An input HIGH (Vi > 8V) will switch the controller on, and an input LOW (V < 2V, or free floating) will switch the controller off. Application example: on/off control by a VE.Bus BMS when charging Li-ion batteries.

Configuring and monitoring

- Bluetooth Smart built-in: the wireless solution to set-up, monitor and update the controller using Apple and Android smartphones, tablets or other devices.
- Use the VE.Direct to USB cable (ASS030530000) to connect to a PC, a smartphone with Android and USB On-The-Go support (requires additional USB OTG cable).
- Use a VE.Direct to VE.Direct cable to connect to a MPPT Control, a Color Control or the Venus GX.
