PWM Solar Charge Controller

PWM solar charge controller is an important part in every solar system. With an MPPT solar charge controller the current is drawn out of the panel at the panel “maximum power voltage". A PWM solar charge controller can be used as an switch for the solar panels and the battery. The best solar panel match for a PWM solar charge controller is a panel that is just sufficiently above that required for charging the battery and taking temperature into account, typically, a panel with a Vmp of around 18V to charge a 12V battery.PWM means Pulse Width Modulation.

PWM solar charge control devices can be explained as electrical switch between batteries. The switch can be quickly switched on and switched off. Thus, the desired voltage can be obtained to charge the batteries. The charge current will slowly decrease as the batteries are charged. PWM solar charge controllers are cheap than MPPT Controllers, so you know, PWM solar charge controllers are very popular and widely used on the condition that in small systems. Anyway, PWM solar charge controllers can provide sufficient performance in small applications which does not need more property.PWM has recently surfaced as the first significant advance in solar battery charging.

PWM solar charge controllers use innovation like other present day excellent battery chargers. At the point when a battery voltage arrives at the guideline setpoint, the PWM calculation gradually diminishes the charging current to abstain from warming and gassing of the battery, yet the charging keeps on returning the greatest measure of energy to the battery in the most brief time. The outcome is a higher charging proficiency, fast re-energizing, and a sound battery at full limit.


What Is a PWM Solar Charge Controller?

The PWM Solar Charge Controller is a standard type of charge controller for solar power equipment. The PWM charge controller is an older technology, which is cheaper than the MPPT controller, but its efficiency is lower than that of the MPPT charge controller.

The PWM solar charge controller is very suitable for those who just started to install a home solar system. PowMr has a high-cost performance, simple installation, intelligent control, and better protection of your battery life.

Advantages of Solar PWM Charge Controller:

  • Cheaper than MPPT controller
  • PWM controller is best for small-scale applications
  • Best performance when the battery is close to full charge
  • Less stress on the battery and fewer damaged components, so the service life is usually longer

Disadvantages of Solar PWM Charge Controller:

  • Lower efficiency than MPPT controller
  • Because solar panels and batteries must have matching voltages with these controllers, PWM solar charge controllers are not suitable for larger and more complex systems.
