A charge controller, or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery. Most "12 volt" panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging. Most batteries need around 14 to 14.5 volts to get fully charged.
LandStar BPL series solar charge controller combines the solar charge controller and LED constant current driver into one unit which is ideal for solar LED Lighting, especially for the application for LED lamp which requires dimmer function. It can also reduce the system cost and increase the system flexibility.

The enclosure of charge controller:
If the controllers are used indoors or outdoors but with box, user can choose IP30 solar controller. For outdoor application, sometimes steam condenses to water when it touches a cold surface. And the water can come into controllers along with the wire. So it’s better to use high IP rating controller in humid area.
- Q:Solar controller can not charge what is the reason
- Are charged control point voltage: direct charge after the end of the battery will be charged and discharged controller for some time, so that the voltage naturally fall, when the fall to the "recovery voltage" value, will enter the charge state. Why are they designed? That is, when the direct charge is completed, there may be individual batteries "backward" (terminal voltage is relatively low), in order to pull these individual molecules back, so that all the battery side voltage is uniform, so it is necessary to high voltage with moderate Of the current and then charge a small meeting, we can see the so-called charge, that is, "balanced charge." Are charged time should not be too long, usually for a few minutes to ten minutes, the time set too long but harmful. For a small system equipped with two batteries, it is not meaningful. Therefore, the street lamp controller is generally not full charge, only two stages
- Q:How to debug a solar street light controller
- Press the button for more than 3s digital tube began to flash, the system into the adjustment mode, release the button, each press a button, digital tube digital will change a number until the digital display of the number of users from the table selected mode corresponding The number of so far, such as digital tube to stop flashing or press the button more than 3s to complete the set.
- Q:Solar controller does not heat how to heat
- Solar energy itself is the hot water of the stuff, certainly can be heated, but not with electric heating only.
- Q:What are the solar controller models?
- Pure light control mode: when there is no sunlight, the light intensity dropped to the starting point, the controller delay 10 minutes to confirm the start signal, according to the set parameters to open the load, the load began to work; when there is sunlight, light intensity rose to the starting point, The controller delays 10 minutes after confirming the shutdown signal and turns off the output. The load stops working. Light control + time control mode: start the same process and pure light control, when the load to set the time to automatically shut down, set the time 1 to 14 hours. Manual mode: In this mode, the user can press the button to control the load on and off, regardless of whether the day or night. This mode is used for some special load or debug mode when used in debugging: for system debugging, when the optical signal is closed, no light signal load, easy installation and commissioning check the correctness of the system installation. Normally open mode: The power-on load remains in the output state, which is suitable for 24-hour power supply.
- Q:How to adjust the solar controller
- The controller is designed for solar DC power supply system, solar DC street lamp system design, and the use of a dedicated computer chip intelligent controller. Use a one-touch touch switch to complete all operations and settings. With full short-circuit, overload, unique anti-reverse protection, full, over-automatic shutdown, recovery and other full-function protection measures, detailed charge instructions, battery status, load and a variety of fault instructions.
- Q:How the solar controller wiring,
- Carefully follow the instructions on the wiring
- Q:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
- Solar controller uses high-speed CPU microprocessor and high-precision A / D analog-to-digital converter, is a computer data acquisition and monitoring and control system. It can collect the working data of the PV station in real time, obtain the working information of the PV station at any time, and accumulate the historical data of the PV station in detail, and provide the accurate and reliable evaluation of the reliability of the PV system design and the reliability of the quality of the inspection system Full basis. In addition, the solar controller also has a serial communication data transmission function, can be a number of photovoltaic systems sub-station for centralized management and remote control.
