★【Upgraded MPPT Solar Controller】The newly upgraded solar controller adopts advanced MPPT maximum power point tracking technology algorithm. It automatically recognizes the battery voltage of 12V/24V/36V/48V, and the charging efficiency is improved by 5% -10% compared to general controllers.

★【Large LCD Display】Support the display of battery working status, solar panel working status, mode control, load output status and various parameters, as well as normal and fault status.

★【7 Operating Modes】There are 7 modes that can be switched: charging mode, light control mode, light control+delay mode, universal mode, manual control mode, timed control mode, and testing mode.

★【Multiple Battery Charging Options】The solar charge controller is compatible with various types of batteries, including Seal, GEL, Flooded, and LifePO4.

★【Dual USB Charging Interface】The solar charging controller adopts a dual USB charging port design, which can charge two devices at the same time. It supports most USB port devices, such as mobile phones, tablets, PSP game consoles, Bluetooth headphones, cameras, and other digital products.

★【Multiple Protection】The MPPT solar controllers provide extensive voltage protection, including protection against battery overvoltage, overcurrent, power outage, overcharge, deep discharge, overheating, and more.

2. In order for the controller to correctly identify the battery voltage, the first connection must ensure that the 12V battery voltage is higher than 10V; the 24V battery voltage is higher than 20V; the 36V battery voltage is higher than 30V; the 48V battery voltage is higher than 40V).
