Steca Solarix PRS 1515 12/24v (15 amp) Solar Charge Controller

Sorry, this product is no longer available.

The 15 Amp Steca Solarix PRS 1515 is a cost-effective, yet high quality solar charge controller.

The range of Steca Solarix PR charge controllers were launched in the year 2004 as the fifth generation of charge controller technology (up to 900 Wp). The heart of the charge controller is the integrated circuit called ATONIC®II, which contains the improved regulation software based on a self learning algorithm. It will prevent your solar panels of approx 50-250 watts (Dependant on battery voltage), from overcharging your battery.

The Steca Solarix PR 1515 charge controller is highly featured with automatic voltage regulation, temperature compensation, reverse polarity protection and more. The LED keeps you advised of battery voltage etc. The charge controller uses Pulse Width Modulation (PWM) for optimum battery charging and in short... provides reliable protection for both 12v and 24v systems.
