Title: Basics of Solar Charge Controller A solar charge controller is an electronic device which manages the power going into the battery bank from the solar array. It ensures that the deep cycle batteries are not overcharged during the day and that the power doesn’t run backwards to the solar panels overnight and drains the batteries.
Why should we need Solar Charge Controller? Solar charge controller basically controls the device voltage and opens the circuit, halting the charging, when the battery voltage ascents to a certain level. More charge controllers utilized a mechanical relay to open or shut the circuit, halting or beginning power heading off to the electric storage devices.
Benefits of Solar Charge Controller:
Protects the battery (12V) from over charging
Reduces system maintenance and increases battery lifetime
Auto charged indication
Reliability is high
10amp to 40amp of charging current
Monitors the reverse current flow
What is MPPT Solar Charge Controller? It is an electronic device which manages the power going into the battery bank from the solar array. Solar charge controller ensures that the deep cycle batteries are not overcharged during the day, and that the power doesn’t run backwards to the solar panels overnight and drain the batteries. It is available in two different technologies, PWM and MPPT. An MPPT charge controller is more expensive and highly efficient than a PWM charge controller, and it is often worth it to pay the extra money. Unlike PWM controllers, MPPT charge controllers can pair non-matching voltages from panels and batteries. MPPT controllers adjust their input to bring in the maximum power possible from your solar array, and can also vary their output power to match the attached battery. This means that MPPT charge controllers are more efficient than PWM controllers, and more effectively utilize the full power of your solar panels to charge a home battery system.
