Solar PV Charge Controllers

Solar PV Charge Controllers

The solar charge controller regulates the power going from the solar panels to the batteries.
Detailed Description

PV Panel’s open circuit Voltage is 21.6V and we need to charge battery in between 14V to 15V so we need a Solar PV Charge Controller.You will need a controller to prolong the battery life of your PV System. The most basic function of a controller is to prevent battery overcharching. If batteries are allowed to routinely overcharge, their life expectancy will be dramatically reduced. A controller will sense the battery voltage, and reduce or stop the charging current when the voltage gets high enough. This is especially important with sealed batteries where we can’;t replace the water that is lost during overcharging.The only exception to controller need is when the charging source is very small and the battery is very large in comparison. If a PV module produces 1.5% of the battery’;s ampacity or less, then no charge control is needed. System controllers, PV controllers can open the circuit when the batteries are full without any harm to the modules. Most PV controllers simply open or restrict the circuit between the battery and PV array when the voltage rises to a set point. Then, as the battery absorbs the excess electrons and voltage begins dropping, the controller will turn back on.
