20A MPPT Pro Plus Charge Controller

The PV Logic MPPT Pro Plus charge controller has been designed to deliver the highest possible power from any 12v or 24v solar panel into a 12v or 24v battery. The MPPT (multi power point tracking) technology increases solar yield by up to 20% over a standard PWM charge controller. Solar panel performance and the state of charge in the battery can be monitored via a smartphone or tablet using the free to download Bluetooth app. ... View more

Product information


MPPT (multi power point tracking) technology increases solar yield by up to 20% over a standard PWM charge controller by artificially modifying the voltage coming from the solar panel by actively matching it to suit what a battery or batteries require, whatever state of discharge they may be in. This advanced algorithm ensures that whatever the weather conditions, a solar panel or panels will deliver the maximum power to a battery/s and with the minimum of electrical losses.

To ensure you have complete visibility of how your solar system is performing, a free to download Bluetooth App delivers live and historic data to monitor charge and discharge rates

The 20Ah MPPT Pro Plus provides protection for a battery against overcharging for any 12v solar panel or solar array up to 260w (520w for 24v) and is either an excellent choice for new installations or as an upgrade to an existing solar systems. Whether for leisure (caravan, motorhome, boat), industrial or solar off grid systems the MPPT Pro Plus will more than pay back its cost through the extra power it delivers.
