READY PHOTOVOLTAIC KIT WITH TWILIGHT SENSOR FUNCTION - PANEL 20W VOLT POLSKA - VOLTAGE REGULATOR 10A - CONNECTION CABLES - INSTRUCTIONS FOR CONNECTING THE KIT SET CONTENTS: 1. VOLT P-20 PHOTOVOLTAIC POLYMORPHIC PANEL WITH A POWER OF 20W Dimensions: 465 x 350 x 17 mm The set includes cables with a length of approx. 5 meters and crocodile clips for easy connection to the battery Details of how to properly connect the kit can be found in the attached manual. 2. VOLTAGE REGULATOR 10A 12 / 24V WITH TWILIGHT FUNCTION AND 2x USB The controller has a programmable twilight sensor function. It is possible to turn on the connected receiver after sunset for a specific number of hours. In addition, the regulator may be extended with additional panels in the future, thanks to which we can obtain more electricity. The controller charges the batteries with the PWM method. It modulates the voltage range from 0 to , which allows for quick and stable charging of the battery regardless of the weather and the condition of the solar system. DOUBLE USB Controller settings: Enabling / disabling receivers. Twilight switch (turning on receivers for a given time after sunset). Programmable up to 15h. Regulator protections: Solar battery short circuit. Load side overload. Reverse battery polarity. Overheating protection.
