SainSonic MPPT TRACER 3215RN Solar Charge Controller 30A 12V 24V EP
Product Description
Why we recommend buy MPPT Solar Controller?
MPPT circuit solar controllers are considerably more elaborate than PWM. The
voltage of the solar panel changes with time of day and temperature. The optimum
voltage for battery charging changes as the state of charge of the battery. The
MPPT charge controller matches these voltages and can result in 30% more
efficient transfer of power. This means good MPPT solar charge controllers can
reduce 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 Tie
system because more electricity can be sold back to the grid. While only a small
part of system price, a MPPT solar panel charge controller can leverage the rest
of the system to better performance.

I have just fired up this Controller. I followed the connection sequence and the start-up procedure, and everything turned out perfect, I am currently only feeding in 200 watts of panel power , but I will be adding another 150 watts soon. I love the fact that it can handle up to 150 volts of panel input, so hooking the panels in series allows for much smaller losses through the wiring and more current into the batteries for quicker battery recovery time. Nice construction and clean step through start-up make this unit A+ for me.

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.

I am totally pleased with this unit. It is easy to use and is working perfectly in my small system. I plan to buy a larger version sometime next year.
