Description
This high quality, brand new, powerful 20A 12V/24V solar charge controller is designed to protect batteries whilst charging them, with automatic cut off to prevent over-charging and deep discharge. The controller uses PWM (Pulse Width Modulation) technology which increases charge acceptance and prolongs the life of your battery. Often PWM technology can recover some lost battery capacity.
This controller stops reverse current at night (from the battery back to the solar panel) so your battery won't lose any charge. It has many other protection functions such as over charge / discharge, over load, short circuit, overheating etc. Other features of this controller include LED indicators, temperature sensor, and a load "on/off" button. One of the greatest benefits of this powerful 20A controller is the small size - only 16x8cm.
This controller can work with sealed, gel, and flooded batteries (the default is sealed) or a user-defined battery type (please note battery type can only be changed from default using one of the communication methods listed below). The controller can accept up to 320W (12V battery) / 640W (24V battery) of solar power input, which makes it a perfect choice for small or medium solar PV systems with a battery and load; such as in a campervan or boat.
This model also features advanced communication technology, which offers the user the opportunity to monitor and program parameters for the solar charge controller through various methods.
