- Q:Solar controller can not charge what is the reason
- Float control point voltage: the general charge is completed, the battery is also standing for some time, so that the end voltage naturally fall, when the drop to the "maintenance voltage" point, it entered the float state, are currently using PWM (both Pulse width modulation), similar to the "trickle charge" (that is, a small current charge), a low battery voltage to charge a little, a low charge on the point, an share of a place to avoid the battery temperature continues to rise, This is very good for the battery, because the internal temperature of the battery charge and discharge a great impact. In fact, the PWM method is mainly designed to stabilize the battery terminal voltage, by adjusting the pulse width to reduce the battery charge current. This is a very scientific charge management system. Specifically, at the end of the charge, when the remaining capacity of the battery (SOC)> 80%, it is necessary to reduce the charging current to prevent excessive release (oxygen, hydrogen and acid gas) due to overcharging.
- Q:What are the solar controller models?
- You that the controller is the manufacturer, go to their website under the instructions can be
- Q:How to choose a solar controller
- The choice of solar street light controller, generally in accordance with the current, and the current mainly depends on the battery power and battery voltage ratio and the load power with the battery voltage ratio, who take those who, such as the load is 60W, battery with 100W, battery Voltage 12V, 60W / 12V = 5A, 100W / 12V = 8.333A, so choose 12V10A solar controller
- 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: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:What is the system voltage of the solar controller?
- 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 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
- As long as the voltage is 12V, with more power battery panels can be affected only the problem of charging speed.
- 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:What is the meaning of the DC load above the solar controller?
- Can be batteries, lights, motors and other DC equipment can be used
