Are you in search of a solar charge controller for your off-grid power system? We commonly have two types of charge controllers; MPPT and PWM. The MPPT (Maximum Power Point Tracking) is more advanced to the Pulse Width Modulation technology. Indeed, MPPT solar charge controllers help you convert the excess voltage into amperage and utilize the maximum out of the solar cells. So, here we have a list of the best MPPT controllers.

MPPT Solar Charge Controllers

Of course, there are many lists of the best solar charge controllers on the web. Well, we also had a collection of the best wind solar hybrid controllers earlier on this blog. Today, we are here with a list of the best MPPT solar charge controllers so that you could easily identify the best of the best MPPT machine on the market. And set up your off-grid power systems in its best and the most effective way.

Why MPPT Solar Charge Controllers

Obviously, MPPT solar charge controllers are the most advanced and modern solutions. You get the maximum output from solar cells if you use MPPT technology. It is because an MPPT charge controller works as per the panel voltage and simply turns the extra amperage into power. Moreover, MPPT technology is the best pick for high voltage off-grid power systems. It also helps attain more efficiency in preventing the reverse-current flow. Below, let us check out more things that make MPPT solar charge controllers unique.

  • Increased Charging Efficiency: MPPT solar chargers controllers offer high solar charging efficiency up to 30 percent.
  • High-Power Options: You get high-power variants up to 80 Amps. So, you better go for an MPPT solar charge controller if you are to set up a large off-grid power solution.
  • Increased Input Voltage: It offers the potential ability to set up solar arrays with the increased input voltage than the battery pack.
  • Grid Connect Modules: MPPT technology is the only way to control grid connect modules for charging the batteries.
  • Longer Warranty Period: Finally, MPPT solar charge controllers come with longer warranties than their PWM alternatives.
