Q:The principle of 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:Solar controller can not charge what is the reason
Are charged control point voltage: direct charge after the end of the battery will be charged and discharged controller for some time, so that the voltage naturally fall, when the fall to the "recovery voltage" value, will enter the charge state. Why are they designed? That is, when the direct charge is completed, there may be individual batteries "backward" (terminal voltage is relatively low), in order to pull these individual molecules back, so that all the battery side voltage is uniform, so it is necessary to high voltage with moderate Of the current and then charge a small meeting, we can see the so-called charge, that is, "balanced charge." Are charged time should not be too long, usually for a few minutes to ten minutes, the time set too long but harmful. For a small system equipped with two batteries, it is not meaningful. Therefore, the street lamp controller is generally not full charge, only two stages
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:What is a solar controller?
Solar controller is called solar charge and discharge controller, is used in solar power system, the control of multi-channel solar cell array on the battery charging and battery to the solar inverter load power supply automatic control equipment
Q:How to choose a solar controller
And you have this system has two loads, you want to separate the controller, you can choose a dual controller! And so on and so on, more details can be consulted with me
Q:Solar panels for solar panels
Solar controller is composed of dedicated processor CPU, electronic components, monitors, switching power tubes and other components.
Q:How the inverter is connected to the solar controller
What are your requirements, the inverter is the battery
Q:Choose a solar controller which need to have a few conditions
According to your specific application environment, first determine whether to select the charge controller or charge and discharge controller. Two applications of input and output power level, the input power is mainly solar panels, and the controller is basically in accordance with the current to count. For example, 12V system 120 wrench that should be selected at least rated 10A controller. While the actual system current 7A or so is the other security margin.
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:What is the meaning of the DC load above the solar controller?
Solar power systems are generally DC storage, of course, there are grid-connected power generation, the output is AC, but this system is still relatively small in the country, especially for some small systems. If it is a solar street light system,
