20A MPPT Solar Charge Controller 12V Solar Panel Regulator LCD Display Type-C USB Ports Lead Acid Gel AGM Caravan Camping Off-Grid Solar System

This MPPT solar charge controller is designed for 12V solar panels without an integrated controller and is not compatible with panels that have a built-in controller. It works only with 12V batteries and must not be used with 24V or 36V battery packs. Correct positive and negative polarity is required as the device does not include a polarity converter. Unlike MPPT controllers that draw power around the clock this controller does not consume battery power. A built-in diode prevents reverse current flow so the battery is not drained even when there is no sunlight. The SAE connector allows fast and secure plug-and-play installation. For safe setup connect the solar panel first then the battery ensuring correct polarity. The upgraded LCD screen and LED indicators show system status at a glance and you can select the best charging mode for your battery type. Press the button to view current for 5 seconds after which the display returns to battery voltage. Type-C and USB output ports charge your devices directly from solar or battery compatible with any device using a Type-C or USB cable. Comprehensive protection includes overcharge over-voltage reverse current reverse polarity short circuit and overheat protection. This versatile controller supports 12V lead acid gel AGM and LiFePO4 batteries making it a practical all-in-one solar charging solution for caravans camping boats and off-grid solar systems.
