Steca Solar charge controller PR 2020

For a professional battery charging strategy and load monitoring. State of charge determination and modern charging technology for battery maintenance and control. Module and load current 20 A, system voltage 12 V (24 V). PWM regulation and automatic voltage adjustment. Overcharge and deep discharge protection, as well as reverse polarity protection for module, load, and battery. Protection class IP31, negative grounding of one or positive grounding of multiple terminals possible. Input voltage always 2 V above the battery voltage. With the PR 2020 charge controller, you always have your charging under control; not only do you monitor it, but you also protect the battery, thereby extending its lifespan. The graphic LC display informs you of the operating states using symbols and provides the state of charge in the form of a level indicator. Data such as voltage, current, and state of charge can be retrieved as numbers directly on the display. Furthermore, the controller features an energy meter that you, as the user, can reset yourself.
