Victron SmartSolar MPPT 150/70-Tr Solar Charge Controller — SCC115070211

Solar battery charging for a larger off-grid array

The SCC115070211 is the Victron SmartSolar MPPT 150/70-Tr solar charge controller. It combines maximum power point tracking with up to 70A of battery charging, integrated Bluetooth and a VE.Direct communication interface. Choose it for a properly designed solar and battery system in an RV, marine installation or off-grid property where panel strings, battery chemistry and charging equipment need to work together.

Choose the exact PV connection version

This listing supplies the Tr connection version. Its PV wiring connects through screw terminals, which makes cable termination and terminal access part of the installation plan. It is a different connection arrangement from the MC4 model.

Calculate cold-weather array voltage

The PV input has a 150V absolute open-circuit maximum at the coldest expected conditions and a 145V maximum for startup and operation. Panel open-circuit voltage rises as temperature falls. Have the installer calculate the complete string voltage for the site; a nominal panel wattage or a warm-weather measurement does not prove that the array meets the voltage limit. Exceeding that limit can damage the controller.

Check both current and panel power

The maximum PV short-circuit current is 50A. Nominal solar power references are 1000W for a 12V battery, 2000W at 24V, 3000W at 36V and 4000W at 48V. These references do not remove the voltage, short-circuit-current or connection limits. The charge-current rating describes the battery side, so it should not be treated as the permitted PV input current.

Configure the battery bank correctly

The controller supports automatic 12V, 24V and 48V battery voltage selection; 36V requires manual selection. Configure charging voltages, current and temperature behavior to the exact battery manufacturer requirements. Lithium installations may also require a compatible BMS and coordinated charging controls. Selecting a lithium profile does not replace battery protection or establish compatibility with every battery bank.

Configure and monitor through VictronConnect

Built-in Bluetooth supports local setup and charging-status review through VictronConnect. The VE.Direct interface supports a compatible wired connection. Remote VRM access requires suitable GX equipment, the appropriate connection and internet service. This exact controller does not provide VE.Can ports. An optional display, GX device and project-specific communication cables are separate purchases.

Reserve a protected mounting space

The controller measures 185 × 250 × 95mm in height, width and depth and weighs approximately 3kg. Its electronic components are rated IP43 and its connection area IP22. Follow the manual for protected indoor installation, ventilation, clearance and connection sequence. The operating range is -30°C to +60°C, with full rated output specified to 40°C. An enclosure rating does not make the terminal area suitable for unrestricted outdoor exposure.

Package and buying questions

What does this listing include?

One exact SCC115070211 SmartSolar controller. Solar panels, battery bank, BMS where required, protective devices, installation wiring, inverter and optional monitoring accessories are separate.

Will it supply AC appliances directly?

No. This device charges a compatible DC battery system from solar panels. Household AC loads need a separate inverter sized for running and starting loads.

How should I select between Tr and MC4?

Choose the connector arrangement specified by the system design and check the exact model limits. Similar charging ratings do not make the wiring connections interchangeable.
