MPPT BlueSolar 12V 24V 48V 70A, 250/70TrVE.Can, Victron Energy

MPPT: Ultra fast maximum power point tracking
By constantly monitoring the voltage and current output of the solar panels (PV), MPPT technology ensures that every drop of available energy is taken from the panels and collected for storage. The advantage of this is most visible when the sky is partly cloudy, and the light intensity is constantly changing.

Remote monitoring and control
Remote control and monitoring of the extended features of your charger. Your MPPT by pairing it with your smart phone or other device through VictronConnect connected to the Victron Remote Management (VRM) Internet Portal gives you access to the full power of your MPPT, anytime, anywhere; both services are free. For remote installations - even when there is no internet connection or phone signal nearby - you may be able to monitor the MPPT via Bluetooth pairing with an optional LoRaWAN (Wide Area Network) device.
