Concise Solar Charger Controller for 12V/24V Systems

This solar charge controller is designed to automatically manage the operation of solar panels and batteries in a solar power system. It features several key functionalities and protections to ensure efficient and safe performance.

The controller is compatible with three main battery types: Open (B01), AGM (B02), and GEL (B03). It is important to note that this controller is only suitable for lead-acid batteries, and not for other battery chemistries like nickel-hydride or lithium-ion.

In terms of installation, the system components should be connected in the following order: (1) battery, (2) solar panels, and (3) DC load. It is crucial to ensure that the battery voltage reaches at least 11V before initial use, so the controller can properly detect and register the battery type.

Regarding the LCD screen, it may become blank when the battery voltage is too low. Specifically, when the voltage drops to 8V or below, the controller will shut off to protect the system. After the solar panels have recharged the battery to 12.6V, the controller will resume normal operation and the LCD will become active again.

The controller features several protection mechanisms to safeguard the system. These include overload and short-circuit protection, open-circuit protection, reverse polarity protection, and lightning strike protection. These features help to prolong the battery life cycle and ensure the load operates safely.

The controller is designed for easy setup and operation. It has a user-friendly interface with a display that clearly indicates the system status and data. Users can conveniently switch modes and configure parameters as needed, making it suitable for a variety of applications, including home, industrial, and commercial use.

In terms of technical specifications, the controller supports 12V or 24V battery systems, with a self-consumption of only 10mA. It has a rated charge and load current of 20A. The over-charge protection is set at 14.4V/28.8V, with a floating charge of 13.7V/27.4V. The over-discharge protection is triggered at 10.7V/21.4V, and the recovery voltage is 12.6V/25.2V. The controller also features a USB output of 5V/3A.

The operating temperature range of the controller is -35°C to +60°C. However, it is important to note that during hot, sunny days, the external temperature may reach 60-75°C. To maintain optimal heat dissipation, it is recommended to install the controller in a cool, well-ventilated location.

The controller is constructed using high-quality materials, including a German-imported FR-4 PCB and aging-resistant components. The layout features a clear LCD screen, USB ports, a switch button, and terminals for the solar panels, battery, and load.

In summary, this solar charge controller offers a comprehensive set of features and protections to ensure the efficient and safe operation of a solar power system. Its user-friendly design and compatibility with common battery types make it a suitable choice for a variety of residential, industrial, and commercial applications.
