20A Charge Controller

This is a  powerful 20A solar charge controller with LCD display features advanced monitoring and programming features, offering full control over the charging process and the option to adjust various charging parameters and the load work mode. Users can program their own system settings as opposed to using the factory-defined parameters that many simpler controllers are limited to.

The controller uses PWM (Pulse Width Modulation) technology which increases the charge acceptance of your battery and extends its life. PWM technology can also recover some lost battery capacity.

This charge controller features a full set of electronic protection functions such as stopping reverse current at night (from the battery back to the solar panel), automatic cut off to prevent over-charging and deep discharge, over heating, over load, short circuit and reverse polarity protection.

Compatibility:

This controller can work with solar panels with a combined power of up to 320W (12V battery system) / 640W (24V battery system) / 960W (36V battery system) / 1.2kW (48V battery system) which means that it is suitable even for large off-grid solar systems. The wide solar input voltage range of up to 96V ensures that even on-grid solar modules with a voltage higher than 12V / 24V can be used as an input.

This solar charge controller is designed for use with a single battery or battery bank (gel, sealed or flooded) with a voltage of 12V, 24V, 36V or 48V – the controller will determine the working mode automatically. Note: if you are planning to design a solar charging system with a battery bank / inverter, there is a substantial benefit from using a 48V battery bank (the system will be safer and more stable due to the lower current rating).
