RV Inverter Installation
Professionally installed inverter systems for motorhomes and caravans, designed to safely power your everyday appliances while travelling or freedom camping — fitted at our Christchurch workshop and built for real New Zealand conditions.
Professional RV Inverter Installation
An inverter lets your RV's 12V battery system safely power 230V appliances while travelling or freedom camping. At RV Solutions we design and install inverter systems matched to your vehicle, your power needs and real New Zealand conditions — from our Christchurch workshop.
Whether you're upgrading an existing system or fitting 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 run a wide range of everyday appliances, depending on inverter size, battery capacity and how you use it:
- 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 230V outlets
We'll always explain what's realistic for your setup and recommend upgrades where needed, so you don't end up with a system that underperforms or damages your batteries.
Types of Inverter Installs
From a simple standalone setup to a fully integrated system — we'll recommend the right approach for how you travel.
Stand-Alone System
An inverter that provides AC power independently of your vehicle's electrical system — ideal for basic needs like charging devices or running a single appliance.
Stand-Alone with Dedicated Outlet
A standalone inverter wired to dedicated AC outlets placed where you need them — reliable power points, while staying separate from your main electrical system.
Fully Integrated
Seamlessly connected to your whole electrical system with automatic switching between shore power, generator and battery — the most convenient, capable solution.

Why Professional Installation Matters
Inverters place high electrical loads on your battery system. Done poorly, an install can cause voltage drop, overheating cables, nuisance shutdowns or even fire risk. Ours are designed with:
- Correct cable sizing and protection
- Appropriate fusing and isolation
- Safe ventilation and mounting
- Clean integration with existing 12V and 230V 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.
New Installs, Upgrades & Troubleshooting
No two RVs are the same, so we design around your motorhome, caravan or camper — its battery type and capacity (AGM or lithium), solar and alternator charging, available space and ventilation, and how you actually travel. We work with customers at every stage:
- 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

Complete Your RV Power System
Inverter installs work best as part of a complete power system. These services are commonly combined to improve performance, reliability and off-grid capability.
RV Solar Installations
Solar charging is often essential when running an inverter off-grid. We design and install solar that integrates correctly with your batteries and inverter.

Inverter performance depends heavily on battery capacity and condition. We supply and install AGM and lithium systems designed for inverter use.
Battery upgradesRV Charging Systems
Correct charging is critical when running inverters. We install DC-DC chargers, mains chargers and alternator charging to keep batteries healthy.

What size inverter do I need for my RV?
It depends on what you want to power and how your battery system is set up. Small inverters suit device charging and TVs; larger inverters are needed for microwaves, coffee machines or power tools.
Battery capacity, cable size and charging 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?
Inverters can be bought off the shelf, but installation isn't plug-and-play. They draw high current from batteries, and incorrect wiring can cause voltage drop, overheating, shutdowns or safety risks.
A professional install ensures correct cable sizing, fusing, ventilation and compliance with New Zealand electrical standards and EWOF requirements.
Will an inverter drain my batteries quickly?
It can, if the system is undersized or heavily loaded. A well-designed system balances inverter size, battery capacity and charging sources like solar or alternator charging.
We design systems so you 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, provided the battery capacity and charging setup are suitable.
In many cases, battery upgrades or charging improvements are recommended for reliable performance and battery longevity.
Are inverter installations EWOF compliant?
Inverter installs must meet specific safety and electrical requirements to stay EWOF compliant — correct wiring, protection devices and safe integration with the RV's 230V system.
Our installations are completed with compliance and safety in mind, so you can travel with confidence. See EWOF certification.
Do you install inverters for caravans and motorhomes?
Yes — we install inverter systems in motorhomes, caravans, campers and other RVs. Each install is tailored to the vehicle layout, available space and how the RV is used.
