Solar Charge Controllers

2015-01-17

A Solar Charge Controller is needed virtually in all Solar Power Systems that utilize batteries.

Functions of Solar Panel
Regulating over - charging of the batteries -Regulate the power going from the Solar Panels to the batteries. Overcharging batteries will significantly reduce battery life and at worst damage the batteries to the point that they are unusable.
Block the reverse current from a battery bank from leaking backwards into the photovoltaic array. At night, when Solar Panels are not generating electricity, electricity can actually flow backwards from the batteries through the Solar Panels, draining the batteries. You’ve worked hard all day using Solar Power to charge the batteries, you don’t want to waste all that power! The Charge Controller can detect when no energy is coming from the Solar Panels and open the circuit, disconnecting the Solar Panels from the batteries and stopping reverse current flow.
If your panel size is less than 2W, you do not require a Charge Controller.The Solar Charge Controllers permit Solar Panel Charge Controller to draw maximum power from a panel in your current conditions using its maximum power point tracking feature.


Types of Solar Charge Controllers
1.Maximum Power Point Tracking [MPPT]
This offers the ability to turn extra voltage into amperage by reducing the charge time for the battery.
2.Pulse Width Modulation[PWM]
This reduces the burden to the battery by gradually reducing the power supply to the battery without over charging.
