Victron's Smart Solar MPPT range of controllers help you maximise the amount of energy obtained from your solar panels. Under cloudy sky conditions when light intensity is continually changing, these ultra-fast controllers can improve energy harvest by up to 30% compared with controllers using older PWM technology, and by up to 10% compared with slower MPPT models.
All of the Smart Solar models have Bluetooth communication built-in which allows you to interface with the controller via the VictronConnect app on your Apple/Android/Windows device. Through this app, you can configure an extensive range of functions on your controller and monitor its performance in real-time and via historical stats.
A Smart Battery Sense, BMV-712 or SmartShunt can be used to communicate battery voltage and temperature to one of more of these controllers via Bluetooth, allowing the controller to adjust the output charging voltage to compensate for voltage drop and temperature.
Multiple units can be synchronised in a VE.Smart Network via Bluetooth (10 max.) or via the VE.Can ports (25 max.). This means that all units connected to the network are linked and operating at the same stage of the charging algorithm, so they act as a single, larger charger. When the 'master' unit moves to a different stage of the charging algorithm, all units move with it. This is useful for Energy Storage Systems (ESS) where multiple panels might require the use of several MPPT controllers in order not to exceed their maximum voltage or current ratings.
The SmartSolar MPPT 250/70 VE.Can is capable of working with 12, 24, 36 & 48V systems and auto selects on detection of the battery voltage (software tool needed to select 36V). There is also an optional SmartSolar 'pluggable' display available that attaches to the front of the controller and provides a wide range of data related to charging performance of the solar system, as well as enabling you to configure various controller settings. This display can be fitted permanently or used temporarily.
