In the solar street lamp system, the solar street lamp controller is essential, is connected to the lithium battery, solar panels, LED light source of the central accessories, the role is commensurate with the human brain, therefore, the solar street lamp system malformed operation must choose to match the controller. So how to match the controller with the solar street lamp system, let's analyze from the following aspects:
1. Matching with solar street lamp photovoltaic module panel:
The maximum voltage and maximum charging current of the controller end is greater than the maximum open circuit voltage and maximum charging current of the panel, which requires the power of the panel to be in the scope of the controller can suffer.
2. Match with the battery:
According to the battery type (lithium battery or colloidal battery) choice or set suitable controller (lithium battery system must be based on lithium battery voltage parameters of the controller overshoot overdischarge voltage to set).
According to the battery voltage parameters (12V/24V) choice for the controller (local controller only support 12V battery system).
3. Matching with LED light source:
According to the type of light source to choose suitable controller: booster controller, step-down controller, flat pressure controller, etc. The wiring on the back of the solar panel is reverse buckle design, which can be gently pried open with a screwdriver. The wiring of the solar panel (red cap is connected to the positive pole line, black cap is connected to the negative pole line) corresponding to the positive and negative pole line separated from the black cap of the lithium integrated battery, and the wiring should be wrapped with electrical tape.
According to the LED lamp power, working voltage, current choice of output electrical parameters in line with the request of the controller (output voltage category, output power category, load current setting category).
4, the size of the device, the use of environmental temperature should also accord with the lamp device to reduce the use of the environment. The wiring on the back of the solar panel is reverse buckle design, which can be gently pried open with a screwdriver. The wiring of the solar panel (red cap is connected to the positive pole line, black cap is connected to the negative pole line) corresponding to the positive and negative pole line separated from the black cap of the lithium integrated battery, and the wiring should be wrapped with electrical tape. LED street lamp it is a kind of efficient solid state light source based on semiconductor PN junction formed with weak electric energy can emit light, in a certain forward bias voltage and injection current, injected into the hole in the P region and injected into the N region of electrons in the diffusion to the active region after radiation compound and emit photons, the electric energy directly into light energy.
It is a solid cold light source, with environmental protection, no pollution, less power consumption, high light efficiency, long life and other characteristics, therefore, LED street lighting will become the best choice for energy-saving transformation.
To sum up, each solar street lamp system using controller is not the same, we have to choose a matching controller, only in this way the system can abnormal operation.
