An MPPT solar charge controller from Steca.
Steca Solarix MPPT is a solar charge controller with Maximum Power Point Tracking. It is specially designed to work with all established module technologies and is optimized for solar systems with module voltages higher than the battery voltage. The Steca Solarix MPPT is especially qualified in combination with grid tied solar modules. The advanced MPP-tracking algorithm from Steca assures that the maximum available power of the solar generator is charged to the batteries. The Steca Solarix MPPT with latest technology ensures full performance in all conditions, a professional battery care combined with modern design and excellent protection.
Take the total wattage of your array (number of panels x watts per panel) and divide it by the voltage of your battery bank to get amps, then round up. The amp rating of your charge controller must exceed this number. If you need any assistance sizing your charge controller, please don't hesitate to call us at 888-899-3509 ext 1.
Simply put, if the voltage of your panels is close to the voltage of your battery bank, a PWM charge controller is an affordable choice. However, if your panel voltage is much higher than your battery bank, you should use an MPPT controller because it is designed to convert that higher voltage into amps, which will charge your batteries faster and provide you with a more efficient system.
