Photovoltaic Controller

there are many types solar charge controller from 5A to 400A, which is widely used in solar power station, solar light and so on

Photovoltaic Controller with Medium Power (12v/24v/48v) & Solar Battery Binoculars

1.LCD display function: LCD screen displays important system information to users by number and English, for example: battery voltage, charging and discharging current, work mode, system parameter and system status etc 2.Automatic/manual/night function: it can be programmed and set control method of load as automatic or manual method. While manual method, the load can be opened or closed manually. At this time, night function is in void. While selecting night function, the controller closes the load in daytime. For night detection, it automatically opens the load after a period of time delay. When timing, it automatically closes the load. Time delay and timing can be programmed and set

3.Protective function: protecting the storage battery from over-charging, over-discharging, output overload, overpressure, over high temperature 4.Temperature compensation functions of float charging voltage

5.Fast charging function: when the battery voltage is lower than certain v alue, fast charging will start automatically and the controller will improve charging voltage of battery. When the battery voltage reaches ideal v alue, it starts with count down procedure of fast charging. Once time to regular, it retreats from fast charging status. Therefore, it can fully take advantage of solar energy. 6.Work mode: common charging and discharging pattern, light open and time break pattern and light open and light break pattern.
