A Rugged and Dependable MPPT Controller

Posted

Pros: Small size, lower cost than other MPPT controllers, flexible charging options

Cons: Limited to 15A charge current

A Maximum Power Point Tracking (MPPT) controller is very useful for when you have PV panels that work at much higher voltages than the batteries you wish to charge.  The power delivered is the product of the voltage and the current.  Solar panels that are used on a battery with a regular controller have their working voltage reduced from 15, 16, or commonly 17.5 Volts down to the battery voltage.  This could be as low as 10.5V for a flat battery.  The panel puts out the same current regardless of what voltage it works at so a panel rated at 15W at 17.5 Volts will deliver 0.86A at 17.5V and 0.86A at 10.5V, which is only 9W. An MPPT controller uses inverter technology to convert the voltage...
