Q:Solar controller one machine how
You should include a charge and inverter as one of the machines. This product is also very good, but for many users is not very applicable, such as I hope to enter the input, but the output power can not meet, and configure the inverter is more waste. If your needs and configuration just right, it is still relatively easy to use. The cost of the above is higher.
Q:Solar controller water level display is not correct how to do
Re-adjust the water level to control, choose their own water.
Q:How the solar panels with the controller
Hong-wing HY-12 / 24V10A solar street light controller 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. The controller through the computer core search chip on the battery terminal voltage, discharge current, ambient temperature and other parameters related to the battery capacity sampling, calculated by a dedicated control model to achieve the characteristics of the battery discharge rate, temperature compensation correction of high efficiency, high accuracy Rate control, and adopted a high efficiency PWM battery charging mode, to ensure that the battery work in the best condition, greatly extending the battery life. With a variety of work patterns, output mode selection, to meet the various needs of users.
Q:How to adjust the solar controller
Charging and overpressure indication: When the system is connected normally and the sun is exposed to the photovoltaic panel, the charging indicator (1) is green, indicating that the system charging circuit is normal; when the charging indicator (1) Description of the system over-voltage, the treatment see the fault handling content; charging process using the PWM method, if there have been over-discharge action, the charge must first increase the charging voltage, and keep 10 minutes, and then down to the direct charge voltage, Live activation of the battery, to avoid sulfide crystallization, and finally dropped to the float voltage, and keep the float voltage. If there is no over-discharge, there will be no way to enhance the charge to prevent the battery water loss. These automatic control processes will allow the battery to achieve the best charging effect and to ensure or extend its service life.
Q:Solar controller 10a, a represents what
10A indicates that it can control the maximum current is 10 amps, the use of the load can not be greater than this current.
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:What is the use of solar controller
Solar controller is the power (including battery and electricity), solar panels, the load of the center connector, why say so? Because the above components must be connected with the solar controller in order to be able to achieve the work, in general, the controller's main function is to control the solar panels on the battery charge or disconnect, control the load power supply or disconnect, control the city Electricity and battery switching between the main is that these features, and other, such as light control to open, light control off, timing delay off, manual switch, and debugging and other functions.
Q:What is the meaning of the 30A solar controller?
This 30A proves that the controller has a maximum current of 30A.
Q:Solar controller use
The controller as a core component of solar energy must be a reliable product, otherwise no matter how good the solar system can not play its due role.
Q:What is the power of the solar controller?
Generally in accordance with the current to count. Depending on your system voltage, such as 12V or 24V
