Solar Panel Charge Controller Types

The common types include pwm pulse width modulator and mppt maximum power point tracking.

Solar panel charge controller types.

Simple shunt controllers pwm controllers and mppt controllers. Which types of solar charge controller are the most widely used. There are three different types of solar charge controllers they are. Often if currents over 60 amps are required two or more 40 to 80 amp units are wired in parallel.

Simple 1 or 2 stage controls pwm pulse width modulated maximum power point tracking mppt. The charge process is performed in a smart or intelligent way. The first type shunt controllers are outdated and are not used anymore. This involves varying charge stages voltages and current depending on the type of battery and other factors.

Charge controls come in all shapes sizes features and price ranges. They are very different from each other since they are based on different principles of operation. They range from the small 4 5 amp control up to the 60 to 80 amp mppt programmable controllers with computer interface. The controller directly reads the battery level and once the battery is full it knows to slow down the rate of solar charge to a float keeping is from charging the batteries past 100.

This is important as overcharging the batteries can potentially ruin them. Most charge controllers are a variation of one these four basic types. Solar charge controllers are often referred to as solar regulators as they help control the amount of voltage from the solar modules to the battery and to other loads depending on the type of the controller. There are two main types of charge controllers pwm pulse width modulation and mppt maximum power point tracking ones.

A solar charge controller is designed to receive power from a solar panel or array of panels and use it to charge a battery or bank of batteries. There are three types of solar charge controllers. If you were to get a 20a pwm controller you would be able to regulate a solar panel bank of up to 320w for 12v batteries and 640w for 24v batteries the pwm controller can also be used to connect solar panels to a battery bank of 12v batteries provided that the batteries are the same size and that they are in good condition. Positive ground controller featuring innovative mppt maximum power point tracking technology with high tracking efficiency up to 99 maximizing the energy from solar panels to charge your system.
