MPPT Solar Charge Controller
Maximum Power Point Tracking solar charge controllers (MPPT) 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%. Traditional solar charge controllers reduce the efficiency of one part of your system in order to make it work with another.
Several MPPT solar controllers can accept high input voltages (up to 120V+ 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.
We carry all of the best brands of MPPT charge controllers including Blue Sky, Morningstar, Outback and Solar Charge Converters. Price ranges can run from just over a hundred dollar to at around $600.00. Although this may seem steep the return on your investment will come that much more quickly as your system performance will be significantly improved. 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 and by protecting your battery supply you protect yourself from any unwanted and unneeded replacement costs. Your solar charge controller is an item well worth investing in and researching as your customize your solar panel electric system. Make sure you choose an option that is scalable and appropriate for your power load and make sure that you have sufficient battery storage space for the solar panels you've chosen to install. Use our resources at altestore.com to construct the right solar power electric system for your home or alternate location. We'll advise you on everything from optimizing your current power load to how best to install your solar panels and on choosing the right solar charge controller!
