System connection.
1. Connect the positive and negative battery terminals to the controller as shown in the diagram, the controller will automatically detect the battery voltage.
2. Connect the load positive and negative terminals to the controller as shown in the diagram, be careful not to reverse the connection.
3. Connect the solar panel to the controller as shown in the diagram.
Note: Please strictly follow the above order to access, otherwise the controller may be damaged. The disassembly order is opposite to the wiring order.
Suggestions for safe use.
1. The controller is automatically adapted for 12V/24V lead-acid battery. When installing it for the first time, please make sure that the battery has enough voltage so that the controller can recognize it as the correct battery type.
2. Install the controller as close to the battery as possible to avoid the voltage drop caused by the long wire, which will affect the normal voltage judgment.
3. The controller is only applicable to various lead-acid batteries (including open, sealed, gel, etc.), please do not use it for other batteries (including lithium batteries, NiMH batteries, etc.)
4. This controller can only use photovoltaic panels as the charging source, please do not use DC or other power sources as the charging source. 6. This controller will be hot when running, please note that the controller will be installed on a flat, well-ventilated surface.
