SmartSolar MPPT 150/35

The SmartSolar MPPT 150/35’s ultra-fast MPPT (Maximum Power Point Tracking) technology optimizes solar energy harvesting. It improves energy recovery by up to 30 % compared to PWM controllers and up to 10 % compared to slower MPPT units, particularly under cloudy skies or fluctuating light intensity. The controller also features advanced maximum power point (MPP) detection to maximize energy output even with partial shading.

The SmartSolar MPPT 150/35 delivers a maximum conversion efficiency exceeding 98 %. It is designed without a cooling fan and can maintain its nominal output current up to an ambient temperature of 40 °C.

The SmartSolar MPPT 150/35 includes comprehensive electronic protections, specifically:

Overheating protection and power reduction in case of high temperature.Protection against PV short circuits and PV polarity reversal.Protection against PV reverse current.

No, the SmartSolar MPPT 150/35 is designed without a cooling fan. It can maintain its nominal output current up to 40 °C thanks to its excellent conversion efficiency.

The SmartSolar MPPT 150/35 stores the following trend data for 46 days:

Battery voltage, current, and temperature.Output charge current.PV voltage and current.

The self-consumption of the SmartSolar MPPT 150/35 varies depending on the battery system voltage:

For a 12 V system: 20 mA
For a 24 V system: 15 mA
For a 48 V system: 10 mA

The SmartSolar MPPT 150/35 has the following dimensions (height x width x depth): 130 x 186 x 70 mm. Its weight is 1.25 kg.

The SmartSolar MPPT 150/35 can operate within a temperature range from -30 °C to +60 °C. It maintains its full nominal power up to 40 °C.

The SmartSolar MPPT 150/35 has an IP43 ingress protection rating for its electronic components and an IP22 rating for the connection area.

The SmartSolar MPPT 150/35 is compatible with a wide range of batteries, including lithium, AGM, gel, and flooded lead-acid batteries. It also features a recovery function for fully discharged batteries, even at zero volts, and can reconnect Li-ion batteries equipped with an integrated disconnection function.

The SmartSolar MPPT 150/35 supports battery system voltages of 12 V, 24 V, and 48 V with automatic selection. To select a 36 V system, a software tool is required.

Yes, you can connect solar panels. However, if the connected PV power exceeds the controller’s maximum rated power, it will automatically limit the input power to prevent overload. Maximum PV rated powers are 500 W for a 12 V system, 1000 W for 24 V, 1500 W for 36 V, and 2000 W for 48 V.

Yes, the SmartSolar MPPT 150/35 offers multiple communication options:

Built-in Bluetooth Smart: Enables configuration, control, firmware updates, and synchronization with other SmartSolar controllers via the VictronConnect app.VE.Direct port: For wired connection to a Color Control GX, other GX products, a PC, or other devices.External detection via Bluetooth: A Smart Battery Sense or BMV-712 Smart Battery Monitor can be used to communicate battery voltage and temperature to one or more SmartSolar controllers.

The maximum nominal PV power that the SmartSolar MPPT 150/35 can handle depends on the battery system voltage:

For a 12 V system: 500 WFor a 24 V system: 1000 WFor a 36 V system: 1500 WFor a 48 V system: 2000 WIf a higher PV power is connected, the controller will limit the input power.

The absolute maximum open-circuit voltage of solar panels you can use with the SmartSolar MPPT 150/35 is 150 V in the coldest conditions. The maximum start-up and operating voltage is 145 V.

The charging algorithm of the SmartSolar MPPT 150/35 is fully programmable. You can configure it in several ways:

Via the VictronConnect app, thanks to the integrated Bluetooth Smart connectivity. By selecting one of the eight pre-programmed algorithms using the rotary switch on the device.

You can connect the SmartSolar MPPT 150/35 to a PC or other devices (such as a Color Control GX or other GX products) via its VE.Direct port for a wired data connection.

Yes, for the SmartSolar MPPT 150/35 controller to start, the PV voltage must exceed the battery voltage (Vbat) by 5 V. Subsequently, the minimum required PV voltage for operation is Vbat + 1 V.

The SmartSolar MPPT 150/35 power terminals are designed for cables up to 16 mm² or AWG 6.

No, it is strongly discouraged to use a solar panel array with a PV short-circuit current (Isc) greater than 40 A. Such a current could damage the SmartSolar MPPT 150/35 controller.
