A solar charger gathers energy from your solar panels, and stores it in your batteries. Using the latest, fastest technology, SmartSolar maximises this energy-harvest, driving it intelligently to achieve full charge in the shortest possible time. SmartSolar maintains battery health, extending its life.
The SmartSolar charge controller will even recharge a severely depleted battery. It can operate with a battery voltage as low as 0 Volts, provided the cells are not permanently sulphated or otherwise damaged.
MPPT: Ultra Fast Maximum Power Point Tracking
By constantly monitoring the voltage and current output of your solar (PV) panels, MPPT technology ensures that every drop of available power is rinsed out of your panels, and harvested for storage. The advantage of this is most noticeable when the sky is partially clouded, and light intensity is constantly changing.
Maximum Power Point Tracking (MPPT)
Output current (I) of a solar panel as function of output voltage (V). The Maximum Power Point (MPP) is the point Pmax along the curve where the product I x V reaches its peak.
Output power P = I x V as function of output voltage. When using a PWM (not MPPT) controller the output voltage of the solar panel will be nearly equal to the voltage of the battery, and will be lower than Vmp.
Remote Monitoring and Control
Remotely control and monitor the extensive features of your SmartSolar MPPT charger with built-in Bluetooth by pairing it with your smartphone or other device via VictronConnect. If your installation is connected to the internet with a GX device, the Victron Remote Management Portal (VRM) provides access to the full power of your MPPT, anytime, anywhere; both VictronConnect and VRM are free to use. For remote installations - even when there is no internet connection nearby - you may be able to monitor your MPPT by connecting the GlobalLink 520.
Load output (Certain models only 75/10, 75/15, 100/15 and 100/20 Only)
The intelligent Load output function prevents damage caused by running batteries 'flat'. You can configure the voltage at which SmartSolar disconnects a load - thereby preventing excessive drain on your batteries. And here's the clever bit: SmartSolar will attempt a 100% recharge every day. If it can't - during periods of poor weather - it raises the disconnect voltage, daily, until it achieves success. We call this feature BatteryLife because it maintains the health, and extends the life of your battery.
BlueSolar and SmartSolar MPPT Charge Controllers Overview
Feature highlights common to all models
• Ultra-fast Maximum Power Point Tracking (MPPT). • Advanced Maximum Power Point Detection in case of partial shading conditions. • Outstanding conversion efficiency. • Natural convection cooling. • Automatic battery voltage recognition. • Flexible charge algorithm. • Over temperature protection and power derating when temperature is high.
• Suitable for a variety of battery voltages. Most models connect to 12, 24, and 48V batteries, some only connect to 12 and 24V batteries, or only to 48V batteries. • Charge currents rating from 10A all the way up to 100A. • Maximum PV array Voc voltages ranging from 75V up to 250V. • Multiple chargers can be used in parallel, for large systems we recommend to use the models with a VE.Can communication port.
PV terminal options:
• TR - one positive and one negative screw terminal. • MC4 - 3 pairs of paralleled MC4 connectors.
• SmartSolar models have Bluetooth. • BlueSolar models do not have Bluetooth. They can be retrofitted to have Bluetooth by connecting the VE.Direct Bluetooth Smart dongle. Advantage: the product is not Bluetooth accessible when the dongle is not connected. Note that on the SmartSolar models, Bluetooth can be disabled.
• VictronConnect Application. Connects via Bluetooth or via the VE.Direct - USB interface • MPPT Control. Connects to all models via a VE.Direct cable • SmartSolar Control Display. Plugs directly into the housing of the larger models • GX device • VRM website (GX monitoring device needed)
• VE.Direct - all models • VE.Direct and VE.Can - limited models. VE.Can is especially suitable for systems with multiple solar chargers. All units are simply “daisy chained” to each other with a single RJ45 cable between each unit and also between the las unit in the chain and the a GX monitoring device.
Temperature sensor options:
• Internally (all models). • Externally via the Smart Battery Sense (only SmartSolar models).
Load output options:
• Physical output - On the 10, 15 and 20A models. • Virtual output - via VE.Direct TX digital output cable and the BatteryProtect or a solid-state relay.
Remotely enabling and disabling the charger:
• All larger units feature the Victron standard remote on/off terminals. All models that don’t feature an onboard Remote on/off terminal can be remotely controlled by using the VE.Direct non inverting remote on/off cable – ASS030550310. Note that this prohibits using the VE.Direct port for anything else.
Firmware update options:
• Local updates via the VictronConnect Application (via Bluetooth or USB-VE.Direct interface) • Remote updates via VRM website and a GX device
• VictronConnect Application (free download) • Wire boxes, to cover and protect the terminals. See table on page 2 for wire box types • Control and display panels: MPPT control or SmartSolar control) • GX monitoring device (CCGX, Venus GX, Octo GX or Cerbo GX) • Data cables: VE.Direct cable, RJ45 Cable (VE.Can models only), USB-VE.Direct interface • External control cables: TX cable, non-inverting cable • Bluetooth dongle (for non-smart models)

Optional SmartSolar Control Display
By adding the SmartSolar Control Display you will be able to check the status of your Charger and battery-storage at a glance. Simply plug it into the face of your MPPT charger to provide you with real-time monitoring and set-up capabilities.
SmartSolar Charge Controllers with screw- or MC4 PV connection MPPT 250/60 and MPPT 250/70
Bluetooth Smart built-in
The wireless solution to set-up, monitor, update and synchronise SmartSolar Charge Controllers.
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 BlueSolar algorithm will always maximize energy harvest by locking to the optimum MPP.
Outstanding conversion efficiency
No cooling fan. Maximum efficiency exceeds 98%. The full output current up to 40°C (104°F).
Flexible charge algorithm
