Description
This wiring diagram provides a clear, beginner-friendly explanation of how to correctly wire a Renogy 1000W inverter so that RCD protection functions correctly in a campervan, motorhome, or off-grid vehicle.
Many inverters do not provide a permanent neutral-to-earth bond, which means that while appliances may appear to work normally, an RCD may not trip under fault conditions. This diagram shows how to correctly implement a neutral–earth bond on a Renogy inverter using a contactor, ensuring that the RCD provides shock protection when operating on inverter power.
The wiring arrangement shown is suitable for UK and EU installations and aligns with the principles set out in BS 7671, including Section 721.

Is This Diagram Right for My Van?
YES – this diagram is suitable if:
- You are installing a Renogy inverter in a campervan or motorhome
- Your AC system includes socket outlets or Class I appliances (metal-cased appliances)
- You want your RCD to function correctly when running on inverter power
- You are building a UK or EU-compliant AC electrical system
MAYBE – this diagram may still work, but check first if:
- You are unsure whether your inverter (not Renogy) provides an internal N–E bond
- You are modifying an existing AC installation and want confirmation
NOT SUITABLE – this diagram is not for you if:
- Your installation is outside the UK or EU regulatory framework
- You are looking for a complete DC system wiring diagram
➡️ If you’re unsure, book a quick call and I’ll confirm whether this diagram is right for your van before you buy.
Further Information & Safety Notes
- UK wiring regulations require all socket outlet circuits and Class I appliances to be protected by an RCD.
- Without a correct neutral–earth bond, an RCD will not provide protection against earth leakage or electric shock when operating on inverter power.
- Appliances may still function without an N–E bond, but the absence of RCD protection presents a serious safety risk.
- This diagram shows a safe, tested, real-world wiring arrangement used in compliant campervan installations.
Always follow manufacturer instructions and ensure AC work is carried out competently.
Inverter Compatibility Notice
This wiring diagram has been designed specifically for the Renogy 1000W inverter.
- Some inverter manufacturers (for example, Victron) may include an internal or software-controlled neutral–earth bond.
- Other inverter models may not be compatible with the addition of an external neutral–earth bond.
- Applying an N–E bond to an incompatible inverter may result in equipment damage or unsafe operation.
Always confirm neutral–earth bonding requirements with the inverter manufacturer before installation.

Consultation CTA – Not Sure This Diagram Is Right for Your Van?
AC systems can be confusing, and incorrect earthing or bonding can leave you unprotected even if everything appears to work.
If you’re unsure whether your inverter, consumer unit, or earthing arrangement is compatible with this wiring diagram, you can book a call with me before purchasing.
During the call, I can:
- Confirm whether this diagram suits your AC setup
- Explain how RCDs and neutral–earth bonding work in plain English
- Advise if a bespoke wiring diagram would be more appropriate
This ensures your AC system is not only functional but also safe.
