Professional RV Inverter Installation in Christchurch
An inverter allows your RV's 12V battery system to safely power 240V appliances while travelling or freedom camping. At RV Solutions, we specialise in designing and installing inverter systems that are matched to your vehicle, your power needs, and real New Zealand conditions.
Whether you're upgrading an existing system or installing an inverter for the first time, we focus on safe wiring, correct system sizing, and long-term reliability — not just fitting a box and hoping for the best.
What an RV Inverter Can Power
A correctly specified inverter system can power a wide range of everyday appliances, depending on inverter size, battery capacity, and usage.
- Microwaves and small kitchen appliances
- Coffee machines and kettles (with suitable system design)
- Televisions, laptops, and device charging
- Medical equipment such as CPAP machines
- Power tools and general 240V outlets
We'll always explain what is realistic for your setup and recommend upgrades where needed, so you don't end up with a system that underperforms or damages batteries.
Why Professional Inverter Installation Matters
Inverters place high electrical loads on your battery system. Incorrect installation can lead to voltage drop, overheating cables, nuisance shutdowns, or even fire risk.
Our inverter installations are designed with:
- Correct cable sizing and protection
- Appropriate fusing and isolation
- Safe ventilation and mounting
- Clean integration with existing 12V and 240V systems
- Compliance with NZ electrical standards and EWOF requirements
The goal is simple — a system that works reliably, safely, and predictably when you need it.
Inverter Systems Tailored to Your RV
No two RVs are the same. We take into account:
- Motorhome, caravan, or camper layout
- Existing battery type and capacity (AGM or lithium)
- Solar charging and alternator charging
- Available space and ventilation
- How and where you actually travel
This allows us to recommend an inverter solution that suits both your current needs and future upgrades, rather than a one-size-fits-all approach.
New Installations, Upgrades & Troubleshooting
We work with customers at all stages, including:
- New inverter installations
- Upgrading undersized or outdated systems
- Replacing failed or unreliable inverters
- Integrating inverters with solar and battery upgrades
- Diagnosing performance or shutdown issues
If you're unsure what inverter you currently have — or whether it's correctly installed — we can assess your system and provide clear recommendations.

Frequently Asked Questions
What size inverter do I need for my RV?
The correct inverter size depends on what you want to power and how your battery system is set up. Small inverters may suit device charging and televisions, while larger inverters are required for appliances like microwaves, coffee machines, or power tools.
Battery capacity, cable size, and charging systems all play a role — which is why inverter sizing should be done as part of a complete system design, not in isolation.
Can I install an inverter myself?
While inverters can be purchased off the shelf, installation is not just a plug-and-play job. Inverters draw high current from batteries, and incorrect wiring can cause voltage drop, overheating, shutdowns, or safety risks.
A professional installation ensures correct cable sizing, fusing, ventilation, and compliance with New Zealand electrical standards and EWOF requirements.
Will an inverter drain my batteries quickly?
Inverters can drain batteries quickly if the system is undersized or heavily loaded. A well-designed system balances inverter size, battery capacity, and charging sources such as solar or alternator charging.
We design systems so customers understand realistic run times and avoid unexpected flat batteries.
Can an inverter be added to an existing solar system?
Yes — inverters can often be added to existing solar systems, but the battery capacity and charging setup must be suitable.
In many cases, battery upgrades or charging improvements are recommended to ensure reliable performance and battery longevity.
Are inverter installations EWOF compliant?
Inverter installations must meet specific safety and electrical requirements to remain EWOF compliant. This includes correct wiring, protection devices, and safe integration with the RV's 240V system.
Our installations are completed with compliance and safety in mind, so you can travel with confidence.
Do you install inverters for caravans and motorhomes?
Yes — we install inverter systems in motorhomes, caravans, campers, and other RVs. Each installation is tailored to the vehicle layout, available space, and how the RV is used.
