If you’re looking for an MPPT controller at a bargain rate, the WindyNation

If you’re looking for an MPPT controller at a bargain rate, the WindyNation TrakMax40 Amp controller utilizes a software algorithm to maximize the energy production for your solar panels. Compatible with flooded lead acid, sealed lead acid (AGM), gel and lithium 12V or 24V batteries, this charge controller offers adjustable settings for fine-tuning to a specific battery manufacturer's algorithms.

An LCD display provides all system information such as amps, volts, solar voltage, battery temperature and load control. The TrakMax is made with virgin PC and ABS plastic and features electronic protection against overvoltage, reverse polarity, overcurrent, excessive temperature and short circuits. This fast sweeping controller optimizes the maximum power point in a short time period, allowing for efficiency of up to 99.9 percent.

Other accessories can be added separately like an optional remote monitor that can be mounted up to 20 feet from the controller and can be especially useful if your solar system is located in a difficult place to reach. Or, there's a wireless communication adapter (Bluetooth) that can sync with a smartphone or tablet by downloading the free app.

Headquartered in California, Windy Nation was founded in 2009 to offer DIY solutions to solar installation. The company manufactures the TrakMax controller in China with parts sourced globally, and it's shipped using packaging and printing made from recycled materials. If you have any questions about installation or other solar-related questions, WindyNation has several helpful resource guides available online.
