How to Make Full Use of Solar Energy?
The solar panel role in the solar photovoltaic system, is just to convert sun-light to DC electricity, it cannot store energy, so we use batteries to store electrical energy at the time of excess solar light to be used at the times of no solar light. Mainly in most of places, there are 2 types of solar photovoltaic systems to be used. The first is the grid tie solar system, in which extra generated electricity will be sent back to the electrical grid, and then the solar system owner takes credits from the electric grid to be used in his future bill, and saving his money.
Solar Charge Controller: Working Principle and Function
The system consists of PV module, battery, controller circuit and load. Switch 1 and Switch 2 are the charging switch and the discharging switch, respectively. When switch 1 is closed, the battery is charged by the PV module, and switch 1 also automatically resumes charging the battery according to a pre-set protection mode. When switch 2 is closed, the battery supplies power to the load. When the battery is charged again and reaches the pre-set resuming charging point, switch 2 can automatically resume power supply again.
How to Install the Solar Charge Controller?
If a short circuit occurs at the terminal of the controller, it will lead to fire or leakage and must be very careful. (We strongly recommend to connect the fuse on the battery pack side to 1.5 times of the rated current of the controller), after the correct connection is successfully made. When the sunlight is abundant, the LCD will show the solar panel and the arrow from the solar panel to the battery pack will light up.
MPPT Solar Controller Working principle
MPPT solar control is generally completed through the dc conversion circuit, and the photovoltaic cell array and the load pass through the dc circuit. connected, the maximum power tracking device continuously detects the current and voltage changes of the photovoltaic array, and adjusts the duty cycle of the PWM drive signal of the DC converter according to the changes.
What is a Solar Remote Monitoring System?
The solar power supply system does not need water, oil, steam or fuel when it works. It can generate electricity as long as there is light. It is a clean, pollution-free renewable energy source. It is easy to install and maintain, and has a long service life. Favored by people, it is the leader of new energy. In recent years, the application of solar energy has become more and more extensive in the world, especially in the field of the field, the solar power system is gradually replacing some traditional power equipment, and it is more and more widely used.
Solar Charge Controller Troubleshooting
With the rapid development of the solar industry, solar charge controllers have now begun to spread all over the world, from our home power generation to street lighting, and finally to our transportation solar RV. The solar charge controller has its advantages and disadvantages. The advantage is that it is fully intelligent, fully automatic, and fully humanized. The disadvantage is that it is prone to failure. Buying a high-quality solar charge controller can reduce the occurrence of failures. Inverter.com has listed several reasons for the failure for you, hoping to help you.
How to Choose a Solar Charge Controller?
The most common use of a solar charge controller is to provide load power for solar inverters and to charge energy storage devices in solar power systems. Before buying a solar charge controller, we need to have a general understanding of this product, so as to choose a great solar charge controller with the most favorable price.
Functions of Solar Charge Controller
The solar charge controller is a device used to control the solar panel to charge the battery and at the same time give the load control voltage to the voltage sensitive device. The solar charge controller regulates and controls the charging and discharging conditions of the battery, and controls the power output of the solar cell components and the battery to the load according to the power requirements of the load. It is the main control part of the entire solar power supply system.
Solar Charge Controller Price List
The solar charge controller is a device in the solar off-grid independent power supply system that can automatically control multiple solar panels to charge the battery. It coordinates the work of solar panels, batteries, and loads, monitors the charging status, and tells us the current, voltage and battery conditions that the solar panels charge the battery pack. It can effectively prevent battery overcharge, and has anti-reverse and anti-short circuit functions. Inverter.com offers you two kinds of solar charge controllers, Maximum Power Point Tracking (MPPT) controllers and Pulse Width Modulation (PWM) controllers. The following is our solar charge controller price list for your reference. If you want more information, please go to our product's page.
Types of Solar Charge Controller
The solar charge controller is an automatic control device used in the solar power generation system to control the multi-channel solar cell array to charge the battery. It regulates and controls the charging and discharging conditions of the battery, and controls the power output of the solar cell components and the battery to the load according to the power demand of the load. It is the core control part of the entire photovoltaic power supply system.
Calculate Payback Period of Your Solar System
Payback period refers to: In how many years our solar system will return back its fixed and running costs we should pay for. Basically, before proceeding in purchasing/installing any kind of solar system and due to their high initial costs, we need to make economical feasibility study to know how to calculate the payback period and whether this solar system will be profitable project or not.
How to Choose the Best Solar Company?
Correct choice of the solar company that will supply the solar system components is the base, success crucial factor and the first important task you should take care about. You need to find out more details about the solar company and solar components they provide before dealing with a certain. Here below, we shall summarize the clarifications you need to get, and better if it can be written signed/stamped clarifications from the best solar company:
How to Size Batteries and Charge Controller in Off Grid Solar System?
We need to calculate how much energy our loads will need per day, and this can be done simply by knowing the wattage of each device and how many hours it works per day, multiply the wattage per each device by its run time and add all the wattage hours for all device, so can get total energy required for your home per day. Due to losses & inefficiencies, we recommend to multiply total watt hour by 1.5 factor.
What is a Solar Charge Controller?
The solar charge controller is an electronic device that works as a voltage and current regulator in off grid solar system. It is used to charge batteries from solar panels during daytime hours and discharge batteries when there is no enough power coming from the sun or during night hours.
How to Size a Solar Charge Controller?
A solar charge controller is used to manage the power from the solar cells to charge the batteries and supply the load in the solar power system. The charge controller protects the batteries from overcharging or deep discharging, so as to guarantee the safety of the batteries, increase the service life of batteries and then improve the solar system performance. So, really it's worth doing more investigation in your solar system for best sizing a proper solar charge controller. It is the key for longer life and higher efficiency for your battery bank as the charge controller optimizes the power and voltage coming from your solar panels to provide best charging voltage and current to the batteries.
What are Main Components of a Solar PV System?
The solar PV system is constituted by the solar cell, storage battery pack, charge controller, inverter, AC power distribution cabinet, lightning protection system, combiner box, DC power distribution cabinet, environmental monitoring system, monitoring system and other devices.
