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: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:Solar controller one machine how
4LED display status, dual digital display mode of operation (a key operation intuitive, with power saving mode); can also be compatible with 12V system and 24V system (fully compatible) LED lamp operating current size, that is, the first period of work adjustable power ; The second time period, the third time period the power size adjustable, adjustable range of 10% -90%; the first time period, the second time period, the third time period, before dawn lights time adjustable; Tune, that is, after a few days after the delay in time to turn on the lights.
Q:What is the meaning of the 30A solar controller?
Control the superscript of the current should be in accordance with the rated current to the target, rather than the maximum current. That is: the other side of the discharge or charge when the rated current is 30A. If you explain the controller is the maximum current, the basic is substandard products.
Q:How does the solar controller set up Sheung Shui?
Click the timer key, there are addition and subtraction keys can be set, the specific I did not use Norit big, do not know, you still consult their customer service department, the instructions should also have.
Q:Solar controller does not heat how to heat
The above heating of the controller is in the absence of the sun and you need to use hot water to add, so that you can use hot and cold weather.
Q:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
Solar controller is called solar charge and discharge controller, is used in solar power system, the control of multi-channel solar cell battery charging and battery to the solar inverter load power supply automatic control equipment.
Q:How to debug a solar street light controller
Debug mode (6 ·): used for system debugging, when the optical signal is closed load, no light signal load, easy installation and commissioning check the correct installation of the system. Normally open mode (7 ·): The power load remains in the output state, which is suitable for 24 hours power supply.
Q:Choose a solar controller which need to have a few conditions
The controller should have battery overvoltage protection, battery undervoltage protection, load short circuit protection, temperature compensation and other functions, select the controller to choose the quality of the guarantee. Big manufacturers big brand
