The AIMS Power Rapid Solar Disconnect Switch and Cable Entry Port (PV-RSD1) is a two-part system for RVs, trailers and other solar-equipped vehicles. The Rapid Shutdown Disconnect Switch (RSD) mounts where you can reach it, and the Cable Entry Port (CEP) mounts on the roof.
It lets RV owners and installers shut down solar power at the source for maintenance or weatherproofing without climbing onto the roof. AIMS lists Patent US 12,489,396 B2 for the prewired system.
The system shuts down solar power automatically if no 12V power is present. AIMS says it de-energizes at the PV module level if the battery fails or is disconnected, preventing voltage and current from traveling into the RV or trailer. A push switch lets you shut it down by hand.
A keyed lock adds a layer of safety by helping prevent unauthorized or accidental operation of the disconnect.
The CEP has MC4 compatible PV inputs and comes prewired with 10 inch bare end leads, a 10AWG pair for the charge controller and a 20AWG pair for the switch. It carries an IP65 waterproof rating.
RV and trailer roofs. Shut down rooftop solar from a convenient spot before weatherproofing or system maintenance.
Weather events. Disconnect the array quickly to help protect your solar system when bad weather is on the way.
Without a disconnect, shutting down solar often means climbing onto the roof to unplug panels. The PV-RSD1 lets you push one switch from an accessible location and also shuts down automatically if 12V power is lost.
AIMS's instructions call for a ½ inch hole for the RSD lead and a ¾ inch hole for the charge controller PV leads, spaced ½ inch apart. Seal the CEP with silicone or sealant suited to your roofing and fasten it through its four mounting tabs. The RSD mounts flush from behind a wall or on the front of a surface. Mounting screws aren't included, and the 10 inch leads need to be extended.
The CEP accepts a PV input of 12 to 160VDC with a maximum current of 40A ±5% and uses a 50A fuse.
Your panels plug into the CEP's MC4 compatible inputs, and the CEP's output leads run to your solar charge controller. The RSD connects to the CEP's shutdown lead and to your 12V battery through a fuse.
Yes. The RSD's relay operates from 10 to 17VDC ±0.5V, and if 12V power is lost, the system shuts down solar power automatically.
Mounting screws are not included.
The AIMS Power Rapid Solar Disconnect Switch gives you automatic and manual shutdown, a keyed lockout and a prewired roof entry port. If you'd like help planning your RV solar wiring, the Outbound Power team is happy to help.
