As it is charging the solar charge controller lets in as much current as the pv panel can generate in order to achieve the target voltage for the charge stage of the controller.
Pwm solar panel charge controller.
This comes into play when the batter bank is full.
For example a 12 volt panel must be used with a 12 volt battery.
Powmr solar charge controller 12v 24v auto 50a solar panel battery controller 50amp pwm solar regulator with dual usb lcd fit for small solar system.
Pwm charge controllers pwm stands for pulse width modulation.
A pwm pulse width modulation controller can be thought of as an electronic switch between the solar panels and the battery.
The switch is flicked on and off as needed pulse width modulated to hold the battery voltage at the absorption voltage.
It functions to protect voltage overshoot and discharge.
The mohoo 20a charge controller features pwm battery charging and is designed to specifically meet rural electrification needs.
The switch is on when the charger mode is in bulk charge mode.
Get it as soon as tue sep 22.
It stands between the solar panels and the battery bank where it regulates the amount of voltage and current reaching the batteries.
It also stops output when the voltage is too low and restore discharge voltage when necessary.

It works through transmitting a series of short charging pulses to your battery and the charge controller will continuously check the charging state of the battery and automatically adjusts the pulse signals to match it.
A solar charge controller protects your batteries by preventing an electrical overload or excessive discharging.
To fully exploit the potential of the mppt controller the array voltage should be substantially higher than the battery voltage.
A pwm pulse width modulated solar charge controller is the traditional style.
A pwm solar charge controller offers a simple user experience combined with a proven time tested design.
