This 10A 12V/24V Maximum Power Point Tracking (MPPT) solar charge controller has a special buck boost technology which converts any voltage from a solar panel to the right charging voltage required by your battery. This controller is one step ahead of conventional MPPT controllers which require the solar panel voltage to be always higher than the battery voltage. For example, it allows a combination of 9V solar panel and 12V or 24V battery. It also has all other benefits of an MPPT controller such as higher energy yield.

The unit features a full set of electronic protection functions such as automatic cut off to prevent over-charging and deep discharge, stopping back feed at night, over load, short circuit and reverse polarity protection.

The LCD display shows a lot of useful information: power, voltage and current for the solar panel and battery, energy counter, temperature, load parameters etc.

Other features include 18 load work programmes, a remote temperature sensor and pre-set programmes for various battery types: sealed, gel, flooded lead acid batteries and lithium batteries. Advanced configuration of battery charging voltages is also possible.

The controller is suitable for solar panels with open circuit voltage up to 40V and maximum power up to 120W (when charging a 12V battery) / up to 220W (when charging a 24V battery).
