Q:How the solar panels with the controller
Light control on + delay off - open delay + light control off the double time mode: the work process is open when the dark load (light control on), delay to set the first time after the closure of the load, turn off the load After the day until the day before the set of the second time to open the load again, to the dawn when the load off (light control off), the night when the load is closed to save power. The controller uses fuzzy control to automatically identify and effectively correct the darkness to the dawn of the entire night time, that is, according to the length of the night to automatically adjust the time to close the load at night to ensure that the load only in the dark and before dawn Set the time period to open, the other time is closed.
Q:The principle of solar controller
In fact, is a power management. Solar controllers are divided into different types of applications, but are basically controlled by solar charging and battery discharge management.
Q:What are the solar controller models?
Contact manufacturers, different manufacturers adjustable model is not the same as our company is this model: (light control + time control, time control, testing three models) Beijing reed hi Yuan New Energy Technology Co., Ltd.
Q:Solar panels for solar panels
Solar controller is composed of dedicated processor CPU, electronic components, monitors, switching power tubes and other components.
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: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 system voltage of the solar controller?
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:Solar controller water level display is not correct how to do
Re-adjust the water level to control, choose their own water.
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 DC load above the solar controller?
Can be batteries, lights, motors and other DC equipment can be used
