solar photovoltaic power systems іѕ a way to use solar energy to generate solar energy to electricity, it is clean, safe and cheap.
The system usually uses solar panels which are made of silicion tο convert sunlight іntο electricity. In this system, there are many different components, including solar panels, battery, solar controller and sometimes a solar inverter for a utility grid system.
The solar panels are the basic and most important components of a solar photovoltaic system, normally it has mono and poly type, when the panel supply the power to the battery, the battery store the engery and convert into epctricity to make loads working.
Then you need a solar controller, solar controller is used to regulate the whole system, protect battery and prolong battery’s life, it provides great help in maintaining the appropriate charging voltage on the batteries. It prevents batteries from over and under charging and block reverse currents. A solar charge controller is the vital solar system component that always monitors and displays exact conditions of the batteries.
The use of a good quality solar Charge Controller will make sure that you get pleasure from the utmost life from your home batteries and the most from your solar systems. Its main function is to maintain batteries utilities for life time. A solar charge controller can sense the charging process completion and prevents batteries from being excessively discharged and overcharged.
With the help of these kinds of technological advancements in solar system related products truly saves lots of time and money in the long run. Whether you are buying one solar panel or installing an extensive array of panels for charging your home batteries don’t forget the values of a Solar Charge Controller. Always look for a charge controller with a minimum of 90% efficiency while operating at full load and rated output voltage.
Also, you can find lots of information resource sites online that provides huge amount of information about solar charge controller and things to consider at the time of buying solar system products. You can also read online articles related to solar charge controller and check instructions and diagrams that helps you in solving your problems come at the time of buying solar controller. The best charge controllers will come with built-in monitoring systems that make it easy for you to determine the performance of your solar system.
If you continue to send out energy to batteries that are already completely charged, you will ruin them. Unfortunately, your wind generator is unable to regulate itself; it will keep on force feeding electrical power into the system as long as the wind is blowing. It's necessary, then, to install a device that regulates the flow of electricity driven to the batteries. This device is known as a charge controller. Charge controllers measure the charge of the battery and either allow the flow of electricity headed to your battery bank run freely, or shut it off completely, keeping the system fully charged yet protected.
Quite a few solar controlers have a “PWM” mode. PWM stands for Pulse Width Modulation. PWM is often used as one method of float charging. Instead of a steady output from the controller, it sends out a series of short charging pulses to the battery – a very rapid “on-off” switch. The controller constantly checks the state of the battery to determine how fast to send pulses, and how long (wide) the pulses will be. In a fully charged battery with no load, it may just “tick” every few seconds and send a short pulse to the battery. In a discharged battery, the pulses would be very long and almost continuous, or the controller may go into “full on” mode. The controller checks the state of charge on the battery between pulses and adjusts itself each time.
The downside to PWM is that it can also create interference in radios and TV’s due to the sharp pulses that it generates.
Pulse Width Modulation (PWM) is the most advanced technology pertaining to charge controllers and they perform constant voltage battery charging by switching the solar system controller’s power devices. When in PWM regulation, the current from the solar panels tapers according to the battery’s condition and recharging needs. Charging batteries using solar power requires challenging technology like PWM for prolonging the batteries’ life. The issue with batteries is that, while charging and discharging, they release lots of gases that can reduce their lives.
An ordinary solar charge controller cannot regulate the charging and discharging that accurately hence gassing problem arises. A PWM system works on algorithms; so the PWM algorithm gradually reduces the charging current to avoid heating and gas releases of the battery, yet the charging continues to return the utmost amount of energy to the battery in the unswerving time. The result is a higher charging efficiency, quick recharging, and a healthy battery at full capacity. Some of the advanced Pulse Width Modulation Charges also have features like recovering lost battery capacity, increase the charge acceptance, equalize drifting battery cells, disulphate (removing excess sulphur deposits) the battery, regulate battery heating & gassing and prolong battery life.
There are many leading manufacturers of PWM based Solar Charge Controllers in the market and choosing the right one can be sometimes quite confusing. To add to worries they don’t come cheap too! Make sure you read the whole manual to know the credentials of the manufacturer; because in the longer run instead of prolonging the battery life they may in fact harm them. So don’t go for low quality cheaper options. Check out manufacturer warranty too as servicing and repairing may be required going forward. Rest assured this technology will be really beneficial for your precious batteries.
