Choosing the Right Solar Charge Controller

Choosing the Right Solar Charge Controller

The difference in MPPT, PWM, and basic charge controllers

Jeff from Missouri Wind and Solar explains the differences and benefits to using various solar charge controllers.  There are so many products on the market that it may be difficult to understand what you need to get the most out of your solar panels, or solar panel array.

Basic Solar Charge Controller

  • Inexpensive
  • Short lifespan
  • Easy to use
  • Great for novice use
  • Function: Simply disconnects incoming voltage when batteries are full

PWM Solar Charge Controller

  • Moderate price range
  • Medium lifespan
  • Easy to use
  • May create interference in radios and TV’s
  • Great for intermediate solar knowledge
  • Special Feature: Pulse Width Modulation – the charge sends pulses to the batteries to constantly check the state of the battery voltage and will determine how fast to send pulses, and how long (wide) the pulses will be.

MPPT Solar Charge Controller

  • Most expensive
  • Increases solar panel efficiency
  • Longest life expectancy
  • Best for advanced solar users
  • Special Feature: Multiple Power Point Tracking – increases the output from solar panels by up to 30%, reducing the need for more solar panels.  Input is up to 530 volts, but emits 12/24 volts.  Best for battery charging, prolongs battery life.

  1. Hi how to connect a 12v turbine 500w 3 phase and a 120v solar together (wire diagram)to the correct controller with dump load and make it 24volt system to the series 24v battery bank.The clear wire diagram is my very big PROBLEM.Appreciate if you can help.I olso want to buy an MW 300GTI grit tie inverter from you so i can use 300w solar and plug in GFI outlet to the house and instractions THANKS A LOT
