1. Connect the 03battery to the controller first (correct polarity required), and the controller will automatically detect the system voltage.
2. Connect the 04load to the controller (ensure correct polarity).
3. Connect the 01solar panel to the controller.
Important: Always follow this connection sequence to avoid damage. Disconnect in reverse order.
To ensure the controller correctly detects the system voltage, please make sure the battery voltage meets the following minimum requirements during the initial connection:
12V battery: above 10V
24V battery: above 20V
48V battery: above 40V
Connection sequence:
Connect the battery to the controller first.
Connect the solar panel to the controller.
Connect the DC load.
Important: Always follow the correct connection sequence to avoid damage to the controller.
Recommended solar panel voltage range:
For 12V battery: 15–50V solar panel
For 24V battery: 30–50V solar panel
For 36V battery: 45–60V solar panel
For 48V battery: 60–90V solar panel
Widely used in off-grid solar systems, including RVs, island installations, remote area power supply, and modular or prefabricated housing. It is especially suitable for integrated water and electricity systems in capsule houses, tiny homes, and mobile buildings, providing efficient and stable energy management for independent living and outdoor applications.
