CMP45 30A/40A/45A 48V SOLAR CHARGE CONTROLLER

Description

CPU controlled CMP*5 solar charge controller is able to adjust the charge current and decide if to supply the loads electricity according to the voltage of battery. The product also has following features: Generally keep the battery on full voltage condition. Prevent the battery from over-charging. Prevent the battery from over-discharging. Prevent supplying electricity from the battery to solar panels during nights. Reverse Polarity Protection for Battery Reverse Polarity Protection for Solar panels When the current of load exceeds the rated one of controller, the controller will activate the protection mode and lock up, the screen shows “Overload”. When short circuit happens, the Controller will activate the protection mode and lock up, the screen show “Short circuit”. When the battery’s voltage is low, the controller will automatically cut off loads from system and resume its working once the voltage of battery is back to normal. Protection from the lightning strike When Controller is normally working, the LCD Screen will show the voltage of battery, charging current and current of loads in turn in every 5 seconds. Controller is always counting and saving the Charging Current Hours and Discharging Current Hours of the Battery. When controller starts up, controller will self-setup the Charging-off voltage, the Load-off voltage and the Load-on voltage according to the voltage of battery. These default parameters are setup as the standard environment temperature is *5℃. According to varies system temperature, the controller will automatically compensate the temperature of the charging voltage. Users could setup the Charge-on or off voltage, the load-off voltage, the Load-on voltage, etc, according to their requirements. To prevent battery from over discharging, Controller will automatically control the lowest Load-off voltage of the load, which is no less than *0V (as per *2V battery) or *0V (as per *4V battery), or *2V (as per *8V battery). If voltage of the battery is less than *0V (or *0V, *2V), the button “-” will stop working. To recover the default parameters, please keep pressing the button “Menu” for over 5 seconds.
