This 20A 12V/24V solar charge controller uses the most advanced Maximum Power Point Tracking (MPPT) technology to ensure that connected solar modules always operate at peak power. MPPT technology constantly searches for the maximum power point of solar modules, maximising the energy output in all weather conditions and temperature. This technology boosts solar module current and produces higher energy yield compared to standard PWM solar controllers.
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, solar panel over voltage, over load, short circuit and reverse polarity protection.
The integrated 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 management programmes for load work, 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 an open circuit voltage up to 100V and maximum power up to 310W (when charging a 12V battery) / up to 620W (when charging a 24V battery).
– Auto 12V/24V battery voltage selection – 3 pairs of terminals (input, battery, load) for wires up to 10mm2 – Maximum solar input 310W (12V battery) / 620W (24V battery) up to 100V – Battery temperature sensor (-24mV/C) – Self-consumption: 12.7mA – Working temperature: -10C to +50C – Size: 15.4 x 13 x 5.3 cm (including mounting edges) – Weight: 515 g
A detailed instruction manual is included.
This product is covered by a 5 year manufacturer warranty.
