NOW WITH BUILT IN BLUETOOTH
Maximum Power Point Tracking (MPPT) is a technique used to get the maximum possible power from a solar panel. It is achieved by putting a variable load on the panel so that it achieves its optimum output voltage, and then converting that voltage to the optimum required by the battery. The effect of this can be to produce output up to 30% higher than a similar panel without this technology. This Victron MPPT charge controller automatically adjusts for 12 or 24 volt systems.
Smart Solar Charger Overview
If you add the Victron Energy Bluetooth Dongle you can read the information on your iPhone or Android device. However to program the charge controller you need either the MPPT Control or the VE USB Direct connection to a computer because as of now the Dongle can not be used for programming.
