20A SOLAR PANEL BATTERY REGULATOR CHARGE CONTROLLER - BLACK IN SOUTH AFRICA

Use single-chip microcomputer as the core of the whole control system, which makes the controller has the advantages of intelligent, strong adaptability, reliable function etc. Always keep the battery on fill voltage condition. Also prevent the battery from over-discharging. Prevent the battery from over-charging. Prevent the battery from over-discharging. Prevent the battery from reverse charging to solar panels during nights. Reverse Polarity Protection for Battery Reverse Polarity Protection for Solar Panels When the battery voltage is low, the controller will automatically cut off the load from the system. If the voltage of battery is back to normal and the load will restart working. Thunder protection According to the battery voltage grade, the controller can automatically set charge-off voltage, the load-off voltage, the load- restore voltage. (The parameter is default under 25¡æ condition, locked by the CPU procedure, cannot adjust.) The controller will automatically compensate the temperature of the charging voltage according to the changes of ambient temperature. Use SMT chip production technology, industrial class chip,advanced technology,quality assurance.. Before connecting to the solar panel, please connect the controller to the battery; do not use solar panel supply power to the loads directly.. Do not use lamplight to charge the solar panel (lamplight is too weak to charge) DC power source to replace the solar panel will cause troubles to controller.. Choose the suitable wire which diameter should not be too small, please refer to the parameter.
