Solar Panel Charge Controller Types

They are very different from each other since they are based on different principles of operation.

Solar panel charge controller types.

There are three different types of solar charge controllers they are. Which types of solar charge controller are the most widely used. Simple 1 or 2 stage controls pwm pulse width modulated maximum power point tracking mppt. Charge controls come in all shapes sizes features and price ranges.

This involves varying charge stages voltages and current depending on the type of battery and other factors. Most charge controllers are a variation of one these four basic types. 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.

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. 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. They work by simply switching a shunt on or off to allow or block current to the battery. This is important as overcharging the batteries can potentially ruin them.

Shunt regulator series regulator pwm regulator mppt charge controller. The common types include pwm pulse width modulator and mppt maximum power point tracking. Often if currents over 60 amps are required two or more 40 to 80 amp units are wired in parallel. The first type shunt controllers are outdated and are not used anymore.

4 stage charging bulk boost float and equalization and temperature compensation increase your battery life and improve your system s performance. The charge process is performed in a smart or intelligent way. They range from the small 4 5 amp control up to the 60 to 80 amp mppt programmable controllers with computer interface. There are two main types of charge controllers pwm pulse width modulation and mppt maximum power point tracking ones.
