Renogy Voyager 10A wiring diagram

These notes cover the new-edition RCC10VOYP / VOYP10, the waterproof 10 A PWM controller shown in Renogy’s 10/20 A Version 1.0 manual. It supports 12/24 V batteries and lists 130 W at 12 V / 260 W at 24 V. An earlier Voyager with different controls requires its own manual.

PV voltage depends on battery-system voltage: the specification table gives 25 V maximum Voc for a 12 V bank, and 55 V for a 24 V bank. Crimp’s single PV ceiling field cannot express the bank-dependent rating. Apply the 25 V ceiling when planning a 12 V system, including the panel’s cold-weather voltage rise.

The four power connections map to PV + / PV − and BATT + / BATT −. The separate temperature-sensor connector is omitted. There is no LOAD output or monitoring-bus connector in the reviewed diagram.

The mechanical table identifies positive grounding. Do not assume the solar negative and battery negative can be bonded together as on a common-negative controller. Keep the PV circuit connected through its labeled controller terminals, and check the grounding arrangement of the complete installation before combining this controller with a negative-ground vehicle or boat system.

Connect the battery first, then the solar panel. The back-view wiring diagram reverses the apparent left/right order relative to a front view, so follow terminal symbols rather than copying a visual orientation.

The wiring example specifies a 10 A battery fuse for the 10 A Voyager. Its solar fuse is an example tied to the illustrated array; choose actual PV protection from the panel and string ratings. Terminals accept 20–6 AWG conductors. The generic distance table is not a substitute for checking ampacity and voltage drop at 10 A, and the manual gives no numeric tightening torque.

Although the enclosure is rated IP67, the installation instructions still call for a vertical, ventilated position protected from direct sunlight, heat and water, with 150 mm above and below. The rating does not protect unfinished cable connections or authorize a sealed flooded-battery compartment.

Select Li with the battery-type button, then manually choose 12 V or 24 V and the appropriate boost voltage. The manual lists 14.2 V as the 12 V lithium default, adjustable in 0.2 V steps, with no lithium float or equalization. In 24 V Li mode, the screen still shows charging-voltage settings as 12 V values; the actual voltage is twice the displayed value. Temperature compensation excludes lithium. Verify the battery/BMS charging limits and temperature permission separately; waterproof construction does not establish low-temperature charging protection.

The catalog uses 25 V as a conservative PV ceiling because its single voltage-limit field cannot represent the bank-dependent rating. The manual permits 55 V only with a confirmed 24 V battery bank; a higher-voltage design needs that model-specific review.
