Solar Charge Controller Steca PR2020
The Steca PR charge controllers were launched in the year 2004 as the fifth generation of charge controller technology (up to 900 Wp).
This high class state of the art product upgrades the Steca Solarix series by a customer designed LCD which shows the accurate state of charge (SOC) in percent and as battery gauge symbol. The heart of the controller is the integrated circuit called ATONIC®II, which contains the improved regulation software based on a self learning algorithm.
Features
- PWM shunt battery charging
- state of charge (SOC) battery regulation
- built in Ah counter
- boost charging
- equalising charge
- float charging
- automatic load reconnection
