Regulator Victron SmartSolar 150/35 - 150/45

More info

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

The SmartSolar MPPT 150/35 charge controller can charge a battery of lower rated voltage from a field of PV panels of higher rated voltage. The controller will automatically adjust to a rated battery voltage of 12, 24 or 48 V.

Ultra-fast location of the maximum power point (MPPT - Maximum Power Point Tracking).

Especially in cloudy skies, when the light intensity is constantly changing, an ultra-fast MPPT controller will improve energy collection by up to 30% compared to PWM (Pulse Duration Modulation) charge controllers, and up to 10% compared to slower MPPT controllers.

Advanced detection of the maximum power point in case of shady conditions

In the case of shady conditions, two or more points of maximum power may be present on the voltage-power curve. Conventional MPTPs tend to crash on a local MPP, which won't necessarily be the optimal MPP. The SmartSolar's innovative algorithm will always maximize energy recovery by locking on the optimal MPP.

Exceptional conversion efficiency

No fan. Maximum efficiency exceeding 98%. Total output current up to 40°C (104°F).

Extended electronic protection

Protection against overheating and reduction of power supply in case of high temperature. PV Short Circuit and PV Reverse Polarity Protection. Protection against PV current reversal.

Internal temperature probe.

It compensates for absorption and float load voltages depending on the temperature.

Automatic battery voltage recognition

The controller will automatically adapt to a 12V or 24V system only once. If a different system voltage is required at a later stage, the change will have to be made manually, for example with the Bluetooth app. See section 1.11.

Flexible charging algorithm

Fully programmable charging algorithm, and eight pre-programmed algorithms that can be selected with a rotating switch.

Three-step adaptive charging

The SmartSolar MPPT charge controller is configured for a three-step charging process: Bulk – Absorption – Float.

Bulk
During this step, the controller delivers as much current as possible to quickly recharge the batteries.

Absorption
When the battery voltage reaches the absorption voltage parameters, the controller switches to constant voltage mode. During shallow battery discharges, the absorption charge time is limited to avoid overloading. After a deep discharge, the absorption time is automatically increased to ensure a full recharge of the battery. In addition, the absorption period also ends when the charging current is reduced to less than 2 A.

Float
During this step, the Float voltage is applied to the battery to keep it in a state of full charge. When the battery voltage drops below the Float voltage for at least 1 minute, a new charge cycle will be triggered.

Remote on/off

The MPPT 150/35 can be controlled remotely by a non-inverter EV remote on/off cable. Direct (ASS030550300). An ELEVATED input (Vi > 8 V) will switch the controller to On – Ignition; and a LOW input (Vi < 2 V, or floating) will switch the controller to Off – Off. Example application: control of the ignition/stop by an EV BMS. Bus when charging lithiumion batteries.

Configuration and supervision

- Built-in Bluetooth Smart: the wireless solution to configure, monitor and update the controller using Apple and Android smartphones, tablets or other devices.
- Use the VE cable. Direct-USB (ASS030530000) to connect to a PC, an Android-powered smartphone and an On-The-Go USB flash drive (USB OTG cable required).
- Use an EV cable. Direct-VE.Direct to connect to the MPPT Control or a Color Control panel or Venus GX.
