Product Description

Why we recommend buy MPPT Solar Controller? 

MPPT circuit solar controllers are considerably more elaborate than PWM. Thevoltage of the solar panel changes with time of day and temperature. The optimumvoltage for battery charging changes as the state of charge of the battery. TheMPPT charge controller matches these voltages and can result in 30% moreefficient transfer of power. This means good MPPT solar charge controllers canreduce the number of solar panels needed by up to 30%- a tremendous benefit.Even if the excess panels are purchased, benefits are realized in a Grid Tiesystem because more electricity can be sold back to the grid. While only a smallpart of system price, a MPPT solar panel charge controller can leverage the restof the system to better performance.

MPPT TRACER 3215RN Solar Charge Controller 30A 12V 24V EP Review

Did some research and wanted to go with a 24v solar pv setup on the roof (520 watts total), but still have a 12v battery bank. You'll need an MPPT controller for this, and the Tracer by SainSonic 30amp controller works great. I have it hooked up to 2x175ah AGM batteries, and it keeps them charged and ready. It's interesting too how it takes a 24 volt input from the solar panels (actually closer to 34 volts in the direct sun), and down converts to a 14.5 volt charge and increases the amperage from about 10 amps from the panels to over 20 amps feeding the batteries. Makes for a quick recharge for my battery bank. I recommend getting the plug-in digital meter so you'll have some idea what's going on with your system.
