Q:Solar panels for solar panels
The use of a single chip and special software to achieve the intelligent control; the use of battery discharge rate characteristics of the correct discharge control. The discharge voltage is controlled by the discharge rate curve of the control point, eliminating the simple voltage control overdosed inaccuracies, consistent with the inherent characteristics of the battery, that is, different discharge rates have different end voltage. With overcharge, over discharge, electronic short circuit, overload protection, unique anti-reverse protection and other automatic control; the above protection does not damage any parts, do not burn insurance;
Q:Solar controller one machine how
Built-in high-precision step-up constant current source, no need to reprovision LED constant current source, can directly drive LED lamp beads, single string up to 18, up to 9 groups in parallel, the output power can reach 160W, to meet all the market LED street lamps;
Q:How to debug a solar street light controller
Pure light control (0): When there is no sunlight, the light intensity drops 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 to start Point, the controller delay 10 minutes to confirm the closure of the signal after the closure of the output, the load stops working.
Q:What is the meaning of the DC load above the solar controller?
Can be batteries, lights, motors and other DC equipment can be used
Q:How to adjust the solar controller
Battery status indication: When the battery voltage is in the normal range, the status indicator (2) is green; if the status indicator is green slow flashing; when the battery voltage drops to undervoltage, the status indicator turns orange; when the battery When the voltage continues to decrease to the overdischarge voltage, the status indicator (2) turns red, and the controller will automatically turn off the output to remind the user to replenish the power in time. When the battery voltage returns to normal operating range, the output enable operation is automatically enabled and the status indicator (2) turns green
Q:How the solar controller wiring,
Controller (English name: controller) refers to the order in the order to change the main circuit or control circuit wiring and change the circuit resistance value to control the motor start, speed, braking and reverse the master device. It consists of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is a "decision maker" that issues a command to complete the coordination and command of the operation of the entire computer system.
Q:Choose a solar controller which need to have a few conditions
To buy a solar controller must know the power of the solar panel and the load power to be used to determine the controller's charging current and discharge current. General solar controller are 12v / 24v automatic identification. Discharge current = load power / 12v, charge current = battery power / battery board voltage. The voltage of the panel can be set with the multimeter DC. The short-circuit current of the panel uses a clamp meter to test the current. So the battery power = voltage * current, basically know the power of the solar panel. The battery charge current will know. The current range of the controller is greater than the charging current of the solar panel and the discharge current of the load.
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.
Q:How the inverter is connected to the solar controller
The controller combines the logic controller and the microprogram controller, both of which have strengths and weaknesses. The combination of logic controller design trouble, complex structure, once the design is completed, can not be modified or expanded, but it is fast. Microprogram controller is easy to design, simple structure, modify or expand are convenient, modify the function of a machine instruction, just repeat the corresponding micro-program; to add a machine instruction, just add a micro-program in the control memory, However, it is done by performing a short process. The specific comparison is as follows: Combination logic controller, also known as hard-wired controller, composed of logic circuit, completely by hardware to achieve the function of the instruction.
Q:Solar controller water level display is not correct how to do
Re-adjust the water level to control, choose their own water.
