How Solar Charge Controllers Extend Battery Life – Guide

Solar power plants, wind power plants, tidal power plants, fuel cells, etc. are intermittent in nature, which means that these energy sources do not produce electricity constantly and at all times of the day. Therefore, they need a battery to store electricity. The battery does not alter or transform the electrical current; it just saves you. When power is not available, the charge stored in the battery is used to power the loads. Batteries are almost always installed with a charge controller.

Charge controllers are important for optimal battery performance. They include a variety of possible displays, from a single red light to digital displays for voltage and current. These indicators can be helpful in driving across the country without a dashboard in your car!

PWM Solar Charger

A PWM solar charger connects the solar panel directly to the battery bank. When charging in bulk, the matrix output voltage is reduced to the battery voltage. Battery voltage increases as it is charged, so the output voltage of the panel also increases. This consumes more solar energy, so it’s important to make sure that the battery bank voltage matches the rated voltage of your solar system. ..

A higher voltage is needed to charge a battery. If the solar panel and battery have the same voltage, the battery will not charge. PWM solar chargers are more expensive and widely used in homes and commercial applications.

MPPT controller

An MPPT controller is an efficient DC-DC converter that maximizes the power output of a panel. Compared to PWM controllers, MPPT controllers are more sophisticated. You can manipulate the input voltage and current of the PV array to set the optimal operating voltage and ensure maximum power generation at all times.

The MPPT controller can be paired with a PV panel that is greater than the rated voltage. This allows the user to choose a type of photovoltaic solar panel that is less expensive or offers more flexibility in terms of size. Additionally, higher voltage arrays mean that there are fewer strings connected in parallel, resulting in less array current and less voltage drop. This saves money by reducing costly copper cables.

Ideal panel for an MPPT controller

-The controller’s performance -The controller’s compatibility with the MPPT software -The controller’s price

Make sure the panel open circuit voltage (VOC) is below the allowable voltage. This will help to protect the equipment and ensure optimal performance. ..

To activate the VOC, the controller must be above a certain voltage threshold. ..

The maximum panel short circuit current (ISC) must be below the specified limit.

The maximum power of the array must be kept under control in order to protect the people.

Final note

How Solar Charge Controllers Extend Battery Life If you’re like most people, you probably rely on your battery to power your devices when the sun isn’t shining. Unfortunately, batteries don’t work as well in low light conditions, and they can quickly lose their charge. Solar charge controllers can help extend the life of your battery by keeping it charged when the sun isn’t shining. ..
