Steca PR 2020 (20A) Charge Controller - SPR2020Off Grid Technologies our proud to be a main dealer for Steca solar charge controllers, a fantastic range of solar PWR regulator products. This range of Steca PR solar charge controllers was launched in 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. Dependant on battery voltage, the Steca PR 2020 will prevent solar panels of approx 50-300 watts from overcharging your battery. The Steca PR 2020 Charge Controller is highly featured with automatic voltage regulation, temperature compensation, reverse polarity protection and more. The LCD keeps you advised of battery voltage etc. The charge controller uses Pulse Width Modulation (PWM) for optimum battery charging and provides reliable protection for both 12v and 24v systems. Features & Benefits
All solar panels (except the 5W &10W) require a voltage regulator to ensure that the battery is not overcharged. We recommend the Steca PR 2020 for installations up to 300 watts.
