MPPT Solar Controller, 100A 12V/24V/36V/48V Adaptive Solar Panel Regulator with Dual USB Backlit LCD Display Clock Display Solar Controller for Gel Flooded LifePO4 Battery

Overview1.This controller automatically adapts to 12V/24V/36V/48V. During the initial installation, ensure the battery has sufficient voltage so the controller can recognize the correct battery type.
2.Install the controller as close to the battery as possible to avoid voltage drops caused by overly long wires, which may affect normal voltage detection.
3.This controller is compatible with various lead-acid batteries (including open, sealed, gel types) and lithium batteries (for lithium batteries, you need to manually adjust the overcharge voltage). Do not use other types of batteries (such as nickel-metal hydride batteries).
4.This controller can only use photovoltaic panels as a power source. Do not use DC or other power sources as a charging source.
5.The controller generates heat during operation. Ensure it is installed on a flat, well-ventilated surface.
