Wiring Steps

Do not insert the wires into the space below the socket/hatch. This will damage terminals because of loose connections.

Step 1.

Loosen the screws above the terminals to make the socket/hatch descend.

Step 2.

Insert the wires into the socket/hatch. The terminals on the Rover 40A can accept up to 8AWG of wires.

Step 3.

Tighten the screws to elevate the socket/hatch to complete the wiring.

Connect and set the battery type

The first step in setting up the charge controller is to connect it to a battery. After that, you can easily set the battery type using the arrow keys on the controller.

Connection of a Temperature Sensor

Connect the label port on the controller, then place the sensor inside the battery compartment. You can tape the sensor to one side of the battery for secure placement.

Mounting On a Flat Surface & Bluetooth Connection

The package includes mounting brackets that can be used to mount the Rover on any flat surface. You can purchase an additional BT-2 Module to connect to the Rover using the RS485 port, allowing you to monitor and directly change parameters via the app.

Connect to the Solar Panel

The final step is to connect the solar panel using the adapter kit to the Rover. Once connected successfully, the PV voltage will be displayed on the LCD screen.

Frequently Asked Questions

1. How should I wire my panels with an MPPT charge controller?

The panels can be wired either in series or parallel or a combination of series/parallel.

2. What is the max wattage input on the Rover 40?

The Renogy Rover 40A MPPT Solar Charge Controller can accept input of up to 520W for a 12V system, and up to 1040W for a 24V system.

3. Does the Rover 40A MPPT charge controller have a built-in 40A fuse for the rated 40A load output?

No. Please always add a fuse between the charge controller and batteries. To determine the fuse size, you can match it to the amperage rating of the charge controller. If you have one of our 40A charge controllers, we recommend using a 40A ANL fuse.

4. What are the advantages of Renogy MPPT technology?

Renogy Rover Series solar charge controllers use Power Catcher MPPT algorithm to always ensure the charge controller converts most energy by locking to the most optimal maximum power point.

5. How many watts can Renogy Rover 40 amp charge controller handle?

The Rover MPPT charge controller can work with standard off-grid 12/24V solar panels with high voltage or multiple panels with voltage up to 100V. And the maximum combined input solar power is 520W for a 12V battery system or 1040W for a 24V system. In particular, this controller will significantly increase the efficiency of a solar system where the solar panel voltage is much higher than the battery voltage.

6. What is a Solar Charge Controller and what is MPPT?

The Charge Controller takes the power made by the solar panels and transform the ‘solar panel power’ into a form of power that the batteries can use. MPPT stands for Maximum Power Point Tracking, and it relates to the solar cell itself. Each solar cell has a point at which the current (I) and voltage (V) output from the cell result in the maximum power output of the cell. MPPT ensures that you get the most power possible from your solar panels at any point in time. It is particularly effective during low light level conditions.

7. What does 40A on MPPT charge controller mean?

40A represents the maximum amount of current the controller can output to the batteries.

8. What are the advantages of Renogy MPPT technology?

Renogy Rover series solar charge controller uses the most advanced Maximum Power Point Tracking (MPPT) technology to track solar panels' maximum power voltage point as it varies depending on sunlight exposure and temperature. This technology ensures the maximum efficiency of your solar system and significantly outperforms standard PWM solar controllers. Another benefit of MPPT technology is the wide solar input voltage range. This controller can work with standard off-grid 12/24V solar panels and with high voltage or multiple panels with voltage up to 100V.
