Wiring Instructions
Follow these steps for safe and correct wiring. Always connect the battery first, then the solar panel, and finally the load. Disconnect in reverse order.
- Prepare Wires: Ensure all wires are cut to the appropriate length and stripped correctly. The Rover 40A can accept up to 8AWG wires.
- Connect Battery:
Loosen the screws above the battery terminals (marked with '+' and '-') to make the socket/hatch descend. Insert the positive battery wire into the '+' terminal and the negative battery wire into the '-' terminal. Tighten the screws to secure the connection. Ensure a firm connection to prevent loose contacts.

- Connect Solar Panel:
Similarly, loosen the screws above the solar panel terminals (marked with '+' and '-') and insert the positive solar panel wire into the '+' terminal and the negative into the '-' terminal. Tighten the screws securely.
- Connect Load (Optional):
If connecting a DC load directly to the controller, loosen the screws above the load terminals and insert the positive and negative load wires. Tighten the screws. The controller offers 5 load modes for management.
- Connect Temperature Sensor:
Plug the temperature sensor into its dedicated port on the controller. Place the sensor near the battery to ensure accurate temperature compensation during charging.
- Connect Bluetooth Module:
Plug the BT-2 (or BT-1) Bluetooth module into the RJ45 communication port. This enables wireless monitoring and parameter adjustment via the Renogy DC Home App.
Important: Do not insert wires into the space below the socket/hatch, as this can damage terminals due to loose connections.

This aids in understanding the controller's operational status.
Refer to the diagram above for a detailed explanation of each indicator and display element. Use the buttons below the LCD to navigate menus and adjust parameters.
Battery Type Selection
It is crucial to select the correct battery type on the controller to ensure proper charging and prolong battery life. For Lithium batteries, use the user mode to manually set parameters if needed, addressing voltage matching issues.
Charging Process
The controller employs intelligent charging algorithms:
- Lead Acid Batteries: Bulk, Absorption, Float, and Equalization stages.
- Lithium Batteries: Bulk and Absorption stages, with Lithium Reactivation capability.
These stages optimize charging efficiency and protect the battery from overcharging.
Bluetooth Monitoring (Renogy DC Home App)
With the included Bluetooth module, you can monitor your system and customize parameters remotely using the Renogy DC Home App on your smartphone. Download the app from your device's app store and follow the in-app instructions to connect to your controller.
