Buying Guide: How to Choose the Right RV Inverter Transfer Switch
Do you need a two-source versus a multi-source ATS?
Two-source ATS units are common for RVs using either shore power and an inverter or shore power and a generator. If you have more than two potential sources, ensure the switch supports multi-source inputs and the correct amperage for your system.
What amperage matches your system?
RV electrical systems typically use 30A or 50A shore power. Select an ATS that supports your expected input/output amperage (for example, 30A units are common in mid-size RVs). Mismatched amperage can lead to overheating or wiring constraints.
What about transfer time and purpose?
Transfer times vary from under 12 ms to tens of milliseconds. Shorter times reduce the chance of interruption for sensitive electronics, but most household devices tolerate brief transitions. Consider your critical devices when evaluating ATS speed.
Installation considerations
Check cabinet or exterior panel space, wiring routes, and whether the unit requires special mounting hardware. Some models include pre-punched holes for quick install, while others demand more customization. Verify compatibility with your inverter’s output type (pure sine wave versus modified sine wave).
Durability and environmental tolerance
RV environments can be harsh. Look for units with heat-resistant ABS housings, good corrosion resistance, and secure mounting features. Outdoor installations may require weather-resistant enclosures and protective mounting.
Smart monitoring and control options
Some inverters include Bluetooth or app-based monitoring. If remote monitoring is important, consider models with built-in Bluetooth or remote control options to track power source status and transfer events.
Important caveats
Always verify that the ATS wiring, inputs, and outputs align with your inverter and shore power configurations. Do not exceed the switch’s rated amperage. If in doubt, consult a licensed electrician or the device manufacturer’s installation guidelines.
Frequently Asked Questions
- What is an RV inverter transfer switch?
An ATS automatically switches power between sources like shore power, generators, and inverters to keep electrical loads uninterrupted.
- Do all RVs need an ATS?
Not all, but any setup with multiple power sources benefits from an ATS to prevent backfeeding and power interruptions.
- Can I install an ATS myself?
Some units are designed for DIY installation with pre-punched holes and clear wiring diagrams. Complex setups may require professional wiring.
- What amperage should I choose for my RV ATS?
Match the ATS to your highest anticipated load and shore power, typically 30A or 50A for most RVs.
- Are pure sine wave inverters required with ATS?
Pure sine wave inverters are preferred for sensitive electronics. Ensure the ATS is compatible with your inverter’s output type.
- Will an ATS prevent generator backfeed?
Yes, properly installed ATS units help prevent backfeeding and ensure safe transitions between sources.
