Overview

I wanted the ability to turn on my inverter when not in the camper, so I added a RF Relay.

Renogy Wired Switch Schematic

RF Relay

I went with a keychain RF switch that has both a ON and OFF button.

QIACHIP Mini Wireless Remote Control Switch DC 6V 12V 24V 1 Channel RF Relay Latched Switch for LED Light, Car Battery ON/Off

Wiring

One side of the rocker switch has the battery's voltage on it so I used that as my power source for the relay.

Pairing the Remote

To set this relay in latched mode, click the learning button 3 times on the relay and then push the ON button followed by the OFF button on the remote.

After that, you should be good to go.
