RV Electrical Upgrades
Professional RV electrical upgrades including batteries, inverters, solar and charging systems, designed and installed at our Christchurch workshop for safe, reliable performance in New Zealand conditions.
Professional RV Electrical Systems in Christchurch
RV electrical systems combine 12V and 230V circuits, battery charging, solar integration and AC power to deliver reliable energy for appliances and off-grid travel. Many factory installations are undersized or poorly designed for long-term freedom camping and extended New Zealand journeys.
At RV Solutions, we design, install and upgrade complete RV and caravan electrical systems from our Christchurch workshop. Our services include solar integration, battery and inverter installations, fault finding and compliance testing so you get safe, dependable power wherever you travel in New Zealand.
RV & Caravan Solar Installations
Travel further off-grid with a professionally designed solar system for your motorhome or caravan. We install panels, regulators, lithium batteries and inverters tailored to how you camp — reliable power, cleaner installs, and smarter charging wherever the road takes you.
RV Inverter Installation
Power your appliances on the road with a professionally installed RV inverter system. We design and install inverters matched to your battery setup and power needs — delivering safe, efficient 240V power for everyday travel and off-grid living.
RV Battery Upgrades
Upgrade your RV's battery system for longer stays, faster charging and reliable off-grid power. We supply and install AGM and lithium battery upgrades designed to suit your travel style, electrical loads and future expansion.
RV Electrical Testing & Certification
Ensure your motorhome or caravan's 240V system is safe, compliant, and ready to travel. We carry out electrical testing, fault-finding, and certification for new installs, upgrades, and repairs — with clear advice and tidy documentation.
Our RV electrical services commonly include:
- Electrical system design & upgrades Custom electrical layouts designed around how you actually use your motorhome or caravan.
- Battery, inverter & charging integration Ensuring all components work together efficiently and safely.
- Fault finding & repairs Diagnosing and correcting electrical issues that affect reliability or safety.
- Safety testing & certification Electrical testing and EWOF work completed to NZ standards.
Why Professional RV Electrical Work Matters
Complex Systems
RV electrical systems are far more complex than standard vehicle wiring, combining 12V DC, 230V AC, multiple charging sources, and safety protection devices in a compact, mobile environment.
Safety First
Incorrect installation or poor system design can lead to unreliable power, damaged equipment, and serious safety risks. Professional work ensures compliance with New Zealand standards.
System Integration
All components must be correctly sized, protected, and integrated to meet New Zealand standards and real-world travel conditions.
Complete Responsibility
At RV Solutions, we take responsibility for the entire system — from design through to testing — so you can rely on safe, dependable power without needing to understand the technical details yourself.
Frequently Asked Questions
An RV electrical upgrade typically involves assessing your current system, determining your power requirements, and installing or upgrading components like batteries, inverters, solar panels, and charging systems. We design the system around how you use your RV, ensuring all components work together safely and efficiently.
The process includes proper cable sizing, circuit protection, and integration of 12V and 230V systems to meet New Zealand electrical standards.
The timeframe depends on the scope of work. A simple battery upgrade might take a day, while a complete electrical system redesign with solar, inverter, and battery installation could take 3-5 days or more.
We provide accurate timeframes after assessing your specific requirements and current system.
Lithium batteries offer significant advantages: lighter weight, longer lifespan (10+ years vs 3-5 years), faster charging, and ability to use more of the battery's capacity. However, they cost more upfront.
AGM batteries are more affordable initially and work well for occasional use. We'll help you choose based on your budget, travel frequency, and power requirements.
Solar panels are highly beneficial if you freedom camp or stay off-grid regularly. They keep your batteries charged without running a generator or needing mains power, giving you more independence and reducing noise.
The amount of solar you need depends on your daily power consumption and battery capacity. We can calculate the right system size for your needs.
Inverter size depends on what appliances you want to run. A coffee machine or microwave might need 1000-2000 watts, while a laptop or TV needs much less (100-300 watts). We also need to account for surge power when appliances start up.
Most RVs work well with inverters between 1000-3000 watts. We'll help you calculate your specific requirements based on your intended usage.
If your motorhome or caravan is self-contained (or you want to certify it as self-contained), you'll need an EWOF (Electrical Warrant of Fitness) for the 240V system. This is a legal requirement and must be completed by a registered electrician.
We provide EWOF certification as part of our electrical services and can ensure all work meets the required AS/NZS 3001.2 standards.
Yes, we regularly work on imported motorhomes and caravans. Many imported RVs have electrical systems designed for different standards or conditions, and often need upgrades or modifications to work optimally in New Zealand.
We can assess your imported RV's electrical system and recommend any necessary upgrades for safe, reliable operation here.
Costs vary significantly depending on what you need. A basic battery upgrade might start around $1,500-$3,000, while a complete system with solar, lithium batteries, and inverter could be $8,000-$15,000 or more for larger systems.
