The Basics of Solar Charge Controllers
Solar charge controllers are mainly designed for two essential things within the solar power system: stop the electricity from the batteries to go through the solar panels when there’s no sun and optimize the charging of the battery cycles by the solar panels.
There are many different solar charge controllers available in the market today. Most have a variety of additional features, which include the capacity to turn DC powered loads on or off automatically, deliver monitoring of the voltage and amp-hours left of the batteries and connect to a data network at home for efficient remote monitoring.
Ways to Size a Charge Controller
Solar charge controllers are specified by voltage and amperage. You will need the right solar controller than can support your solar panel array’s voltage, and then output to the voltage of the battery bank. You will also need to ensure that your solar charge controller has sufficient capacity to handle the current from the solar panel array. You have to take your solar panels’ wattage and then divide it by the voltage of the battery bank to obtain a rough estimate of how many amperes the controller requires.
Another way of sizing a charge controller is by taking the array’s short circuit current and multiple it by 1.56. Just ensure that the solar controller you choose can handle at least that many amperes.
What are the Types of Solar Charge Controllers?
The different types of solar controllers include the following:
MPPT Solar Charge Controllers. The Maximum Power Point Tracking (MPPT) solar charge controller is the latest innovation of solar systems today. This controller can determine the solar panel array’s optimum amperage and operating voltage and match it with the battery bank. This results in additional fifteen to thirty percent more power out of your solar array. See ZHC solar MPPT Controller
PWM Solar Charge Controllers. Pulse Width Modulated (PWM) solar charge controllers are the traditional style of controllers. They are common, widely used in many solar panel applications and very affordable. It is a passive controller technology that utilizes solid state gates and switches to generate a constant DC output from a varying DC input. See ZHC solar PWM Controller
The Main Features of Solar Charge Controllers
Solar charge controllers provide battery bank’s multistage charging, which means that it changes the power amount set to the batteries according to its level for more valuable and healthier batteries. They also stop the solar panels from draining when there is no sun or no power that comes from the solar panels. They also turn off any attached load when the battery is low and then turns it back when it is charged back up.
There are also a variety of solar charge controllers on the market today. There are ,40A solar charge controllers and 30A solar charge controllers that safely control your source of energy and protect your batteries from being overcharged. They also provide essential protection from reverse connection of battery.
In addition, some solar charge controllers provide low voltage disconnect, modifiable control voltage set points and overload metering and protection. They also significantly enhance battery charging, making them a vital component of any solar power system. PWM Solar Charge Controller
The Technology of PWM Solar Charge Controller
With the growing number of residential, commercial and even industrial industries going solar these days, solar systems have become even more popular than ever before. With this, the technology for solar photovoltaic batter charge controllers has continued to evolve over the years. The most innovative technology is the PWM charging, which has become highly popular.
Charging a solar system’s battery is a daunting and unique challenge. Before, there were on-off regulations used in order to limit battery outgassing once a solar panel generated excess energy. However, as solar systems developed, it became even clearer how much such devices interfered with the process of charging. With this challenge, PWM solar charge controller has become the solution.
What is PWM Solar Charge Controller and Its Incredible Benefits?
Pulse Width Modulation is the most effective way to attain constant voltage battery charging by switching the power devices of solar system controller. This new and innovative method of solar batter charging provides some of the impressive benefits of pulse width modulation pulsing, which include:
- Increase the battery’s charge acceptance dramatically
- Ability to maintain high average battery capacity compared to the on-off regulated state-of-charge levels, which are typically fifty-five to sixty percent.
- Adjust automatically for battery aging
- Reduce heating and gassing of battery
In addition to these benefits, the use of innovative PWM Solar Charge Controller over the old technology means reducing the solar system’s cost and the battery disposal issues. It also increases the solar system’s reliability and reduces load disconnects. It also provides the opportunity to reduce the size of battery in order to lower the cost of the system.
If you need more power whenever you it for less money, this product is the right one to consider. It will help you obtain twenty to thirty percent more energy from the solar panels for charging. Stop wasting the energy from your solar system when the battery is only fifty percent changed with the use of PWM Solar Charge Controller.
PWM Solar Charge Controller is also the most common, cost-efficient and the easiest to deploy technology of solar charge controller. Commonly mistakenly referred to as DC to DC converters, this controller is actually a switch similar to a switching power supply that matches the source voltage to the load voltage.
Pulse Width Modulation is quite simple, and it has been around for many decades. One of its incredible advantages is that under most conditions, PWM Solar Charge Controllers won’t take advantage of the panels’ full capacity.
According to Ohm’s law, the current is inversely proportional to voltage, but PWM solar controllers won’t do anything with current. Once the high voltage from the solar panel is converted down to a useable form of 12 volts, the current out will be the same or lesser than the current in.
PWM Solar Charge Controllers are very cost efficient and, they are by far the most common choice for many amateur radio operators. Their price and simplicity make the energy tradeoff a very acceptable compromise.

How a Solar Charges Controller Works?
The main job of solar charge controller is to regulate the energy passing from the solar panel to the battery. They help in properly keeping batteries of your solar power unit by means of preventing them from being under or over charged, as a result, providing long life batteries. The current passing in the solar charge controllers charge the batteries utilized in diverse household items. Also this current could be passed to the invertors for changing direct current or DC to alternate current or AC. At night or if the solar modules are not producing any power or energy, energy could really flow backwards from the batteries to the solar modules, which drain the batteries. A solar charger controller will give you an assurance that this will not happen. Once a solar energy isn’t really passing from the solar panels to the circuit, it cuts off the solar panels from the batteries and stops the reverse stream of current.
