Charging System Solar Panels

What’s the difference between PWM & MPPT

Posted on by Charging Systems
PWM SOLAR CONTROLLER
[Pulse Width Modulation]
It’s a simpler and more affordable technology used in solar charge controllers. PWM controllers regulate the charging process and charge according to the battery actual voltage. When the battery reaches the desired voltage, the PWM controller modulates the width of the charging pulses, reducing the power delivered to the battery.
  • Cost-effective for a small solar system for smaller applications
  • Solar panel voltage drops to match battery voltage
  • User-friendly
  • Known for their reliability and durability
  • Charge efficiency of 70-80%.
MPPT SOLAR CONTROLLER
[Maximum Power Point Tracking]
It’s an advanced technology used in solar charge controllers to optimize the output of solar panels by continuously tracking and adjusting to the maximum power point of the panel’s voltage-current curve.
This allows MPPT controllers to harvest the maximum amount of energy from the solar panels.
  • Suitable for larger applications and multiple panels connected in series
  • Faster charging times and higher energy harvest
  • Converts more solar power into usable electricity
  • Charge efficiency of 95-98%
