SmartSolar MPPT Solar Charge Controller - 250V - 70AMP - UL Approved
A solar charger gathers energy from the solar panels and stores it in the batteries. Using the latest, fastest technology, SmartSolar maximizes 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 sulfated or otherwise damaged.
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 the temperature is high.
Sizing Options:
- 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 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 using 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.
Bluetooth Options:
- 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.
Display Options:

Communication Ports:
- 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 last unit in the chain and the 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.
