MPPT Solar Charge Controllers

MPPT Solar Charge Controllers

Maximum Power Point Tracking (MPPT) Solar Charge Controllers are different than the traditional PWM solar charge controllers in that they are more efficient, and in many cases more feature-rich. MPPT solar charge controllers allow your solar panels to operate at their optimum power output voltage, improving their performance by as much as 30%. In contrast, traditional solar charge controllers reduce the efficiency of one part of your system in order to make it work with another. Read our MPPT charge controller blog to learn more about how you can maximize your power output with MPPT Solar Charge Controllers!

More Info on MPPT Solar Charge Controllers

We carry all of the best brands of MPPT charge controllers, including Blue Sky, Genasun, Magnum Energy, Midnite Solar, Morningstar Corporation, Outback Power, and Schneider Electric (Xantrex). Prices range from just over a hundred dollars to over $1000 for larger units. Although this may seem steep, a good charge controller will hasten the return on your investment by significantly improving your system's performance.

Several MPPT solar charge controllers can accept high input voltages (up to 600 DC) from your solar array, and efficiently down-convert the DC voltage to that of your system (e.g. 12, 24, 48VDC, etc.) which means you aren't losing any generated power and you are able to use what you generate more efficiently. Additionally, using a much higher DC voltage on the input side allows you to use thinner wire, decreasing your wire cost and making installation easier.

Can you charge a 24V battery with a 20V solar panel
and MPPT charge controller?

We compare charging a 24V deep cycle battery bank with a 20V solar panel and a 24V solar panel on a hot summer day with an MPPT charge controller. Because silicon solar panels output a lower voltage in the heat, the voltage output of the solar panels is lower than standard test conditions (STC), so we see if the voltage is high enough to charge the 24V battery bank.

Choosing a well-made charge controller is integral to the long life and efficiency of your entire solar power system. By optimizing the power coming in from your solar panels, you'll get that much closer to offsetting your use of traditional on grid power sources. By protecting your battery supply, you protect yourself from unwanted and unneeded replacement costs. Your solar charge controller is an item well worth investing in as your customize your solar panel electric system.
