Victron SmartSolar 250/60-MC4:
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- 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. 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.
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 Victron Connect. 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 Victron Connect 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.
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.
Bluetooth Smart built-in- The wireless solution to set-up, monitor, update and synchronise SmartSolar Charge Controllers.
VE.Direct- For a wired data connection to a Color Control GX, other GX products, PC or other devices.
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- Fully programmable charge algorithm (see the software page on our website), and eight pre-programmed algorithms, selectable with a rotary switch (see manual for details).
Extensive electronic protection- Over-temperature protection and power derating when temperature is high. PV short circuit and PV reverse polarity protection. PV reverse current protection.
Internal temperature sensor- Compensates absorption and float charge voltage for temperature.
Optional external battery voltage and temperature sensing via Bluetooth- A Smart Battery Sense or a BMV-712 Smart Battery Monitor can be used to communicate battery voltage and temperature to one or more SmartSolar Charge Controllers.
Fully discharged battery recovery function- Will initiate charging even if the battery has been discharged to zero volts. Will reconnect to a fully discharged Li-ion battery with integrated disconnect function.
Remote on-off- To connect for example to a VE.BUS BMS.
Programmable relay- Can be programmed (a.o. with a smartphone)
to trip on an alarm, or other events.
Optional: SmartSolar pluggable LCD display- Simply remove the rubber seal that protects the plug on the front of the controller, and plug-in the display.
