Victron BlueSolar MPPT 100/20 Solar Charge Controller — SCC110020170R

Choose solar charging around your battery system

The SCC110020170R Victron BlueSolar MPPT 100/20 supplies up to 20A of battery charging from a compatible solar array. It combines maximum power point tracking with a VE.Direct interface for compatible monitoring accessories, making it a useful building block for a compact RV, camping or small off-grid battery installation. Select the controller around the complete panel string and battery design, rather than choosing from panel wattage alone.

Choose the connection style for the installation

This controller uses screw-terminal connections for the solar input and battery wiring. Allow room for the correct cable routing, termination and service access. Cables, fuses, disconnects and project-specific connection parts are selected separately for the installation.

Check voltage in the coldest conditions

The maximum PV open-circuit voltage is 100V. Calculate the voltage of the entire series string at the lowest expected site temperature, because a panel’s open-circuit voltage rises as it gets colder. The charge-current rating does not permit exceeding the PV voltage limit. Follow the manual for the required PV-to-battery voltage difference at startup and during operation.

Balance panel power and input current

Victron’s nominal panel-power references are 290W at 12V and 580W at 24V, plus 1160W at 48V. The maximum PV short-circuit current for this exact model is 20A. Panel power, PV short-circuit current, PV voltage and any connector limits all need to suit the design. The 20A charging rating applies to the battery side; it should not be confused with the permitted solar-input current.

Match battery voltage and charging settings

The supported battery selection is 12V / 24V / 48V automatic. Set the charging profile, current and temperature behavior to the battery manufacturer’s instructions. Lithium batteries may require a separate compatible BMS and coordinated charger control. A lithium charging preset does not replace the battery’s required protection equipment.

Choose how you want to monitor charging

Bluetooth is not built into this BlueSolar controller. Local wireless use requires a compatible VE.Direct Bluetooth Smart dongle, sold separately. A suitable VE.Direct wired connection is another supported option. This exact model does not provide VE.Can ports. Remote VRM monitoring requires suitable GX equipment, the appropriate connection and internet access. Monitoring hardware, communication cables and optional displays are separate purchases; this listing supplies the controller.

Use the load output within its separate rating

The controller includes a protected DC load output with a continuous rating of 20A at 12V/24V, but only 1A at 48V. Its low-voltage disconnect can help manage suitable small DC loads. This is not an AC outlet or a general inverter connection. Check the manual and the load’s starting current; a larger inverter normally needs an appropriately protected battery connection rather than being powered through this output.

Reserve space and protect the connections

The unit measures 100 × 131 × 60mm in height, width and depth and weighs approximately 0.65kg. The electronics are rated IP43 and the connection area IP22. Use a protected indoor location and follow the manual for mounting orientation, ventilation, clearance and wiring sequence. The operating range is -30°C to +60°C, with full rated output specified to 40°C. These ratings do not make exposed terminals suitable for unrestricted outdoor installation.

Package and buying questions

What is included?

One exact SCC110020170R BlueSolar solar charge controller. Solar panels, battery, installation wiring, protective devices, inverter and optional monitoring equipment are separate. This SKU is the retail controller package, not a panel-and-battery kit.

Will it power household appliances directly?

No. This is a DC solar battery charge controller. Household AC loads need a separate compatible inverter sized for the running and starting requirements of those appliances.

How do I compare it with another controller?

Compare supported battery voltage, cold-weather PV voltage, PV short-circuit current, charging current, connection style and monitoring requirements. A higher charging-current number by itself does not establish a suitable replacement.
