Steca PR 2020-IP Solar Charge Controllers

The PR 2020-IP design is based on Steca's PR charge controller series. It has an LCD which shows the accurate state of charge (SOC) as a percentage, and also as a battery gauge symbol. The heart of the controller is the integrated circuit called ATONIC II, which contains improved regulation software based on a self learning algorithm.
The Steca PR 2020-IP controller operates in harsh environments, for example where there is salt, moisture or dust. It works on PWM as a low loss series controller.
