Wiring diagram
How the Rover 40A is wired.
Open this example in Crimp to use your own parts and cable lengths. Review the assumptions and installation notes as you adapt the circuit.
Cable sizing for this example
Use the diagram as a starting point for your installation. Replace the example equipment and cable lengths with your own, and check the connections against your exact model's instructions.

Sized against ABYC E-11. The design current is the unit's rated output. The length is one way; voltage drop includes an equal-length return.
Run-length and manufacturer assumptions
The editable example uses 3.048 m (10 ft) runs unless a shorter run is stated. Metric overviews round these to 3 m. Adapt the parts and lengths to your installation before choosing cable and protection.
Supporting parts
- 6.1 m total of 16 mm² (6 AWG) marine cable
- Terminations for 16 mm² cable, matched to the equipment's screw terminals, leads or studs
- 50 A fuse and holder on the positive run
- Heat-shrink, strain relief and terminal boots sized to the cable
Check stud sizes, fuse type, run length and how warm the space gets against the gear you actually have before you order.

Which 40 A controller is covered?
This entry is Rover Elite 40 A, RCC40RVRE-G1, identified in Renogy’s 20/40 A Elite manual. It is a 40 A MPPT for 12/24 V banks, with 520/1040 W respective solar-input ratings and 100 V maximum PV voltage. A Rover Li 40 A with six power terminals is a different product; verify “Rover Elite” on the enclosure rather than choosing a manual by current alone.
How do the four terminals map?
Crimp’s PV + / PV − and BATT + / BATT − map to the four power terminals. The Elite 40 drawing shows the physical order PV+, PV−, battery−, battery+, so the two battery positions must not be inferred from another Rover’s layout. This model has no dedicated LOAD output in the reviewed diagram. The RS485, temperature-sensor and battery-voltage-sensor sockets are omitted from Crimp.
The controller is common-negative. Connect the battery first, confirm the controller has powered up and identified the bank correctly, then connect the solar array. The battery-voltage sensor is a measurement connection, not another charging output.
What wire and fuse information is verified?
The Elite specification allows 20–6 AWG conductors. The manual’s generic distance table is not a model-specific full-load battery-cable schedule: its short-run row lists wires smaller than its own ampacity table permits at 40 A. Size the actual 40 A battery circuit for its installation and voltage drop, within the connector limits.
The reviewed Elite manual does not provide a dependable model-specific battery fuse rating or tightening torque. Those remain gaps to resolve against the installed unit’s instructions; do not borrow the regular Rover 40’s fuse or torque simply because both are 40 A. Protect battery-fed wiring and select PV protection from the real array specification.
How is lithium configured?
In the battery-voltage screen, hold the right-arrow key to enter battery selection. For LI, choose 12 V or 24 V manually, then the lithium boost voltage. The default is 14.4 V for a 12 V bank; the manual permits adjustment in 0.2 V steps. Its Li column omits float and equalization, and excludes lithium from temperature compensation. Select settings approved for the battery/BMS rather than accepting defaults automatically.
Mount vertically with 150 mm clearance above and below. The IP32 enclosure needs a dry, ventilated location protected from water and battery gases.

Describe your setup to draft a system with Rover Elite 40A connected. Review the selected parts and cable lengths, then edit the diagram in Crimp.
The model only picks parts and draws the connections. Every wire size and fuse rating still comes from Crimp's own sizing, never from the model.
