RV Electrical Upgrades
Batteries, inverters, solar and charging systems designed and installed at our Christchurch workshop for safe, reliable power — built for real New Zealand conditions and the way you actually travel.
Complete RV & Caravan Electrical Systems
An RV electrical system ties together 12V and 230V circuits, battery charging, solar and AC power to run your appliances and keep you going off-grid. Plenty of factory installs are undersized or poorly thought out for long-term freedom camping and big New Zealand trips.
At RV Solutions we design, install and upgrade complete motorhome and caravan electrical systems from our Christchurch workshop — solar integration, battery and inverter installs, fault-finding and compliance testing — so you get safe, dependable power right across Canterbury, the South Island and beyond.

RV & Caravan Solar Installations
Travel further off-grid with a solar system designed for your motorhome or caravan — panels, regulators, lithium batteries and inverters matched to how you camp.
RV Inverter Installation
Run your 230V appliances on the road with an inverter matched to your battery setup and power needs — safe, efficient power for everyday travel and off-grid living.
RV Battery Upgrades
Upgrade to AGM or lithium for longer stays, faster charging and dependable off-grid power — sized to your travel style, electrical loads and future plans.
120V to 230V Power Conversions
Converting an imported North-American RV? We bring 120V systems up to New Zealand's 230V standard — inverters, chargers and appliances — safely and compliantly.
RV Electrical Testing & Certification
Make sure your 230V system is safe, compliant and travel-ready. Testing, fault-finding and certification for new installs, upgrades and repairs — with tidy documentation.

Why Professional RV Electrical Work Matters
Complex Systems
RV electrical is far more involved than standard vehicle wiring — 12V DC, 230V AC, multiple charging sources and protection devices packed into a compact, mobile environment.
Safety First
Poor design or a bad install means unreliable power, damaged gear and serious safety risk. Professional work keeps you compliant with New Zealand standards.
System Integration
Every component has to be correctly sized, protected and integrated to meet NZ standards and stand up to real-world travel.
One Point of Responsibility
We take on the whole system — design through to testing — so you get safe, dependable power without needing to understand the technical detail yourself.
RV Electrical Questions, Answered
What's involved in an RV electrical upgrade?
Typically we assess your current system, work out your power requirements, then install or upgrade components like batteries, inverters, solar and charging systems — designed around how you use your RV so everything works together safely and efficiently.
That includes proper cable sizing, circuit protection and integration of your 12V and 230V systems to meet New Zealand electrical standards.
How long does an electrical upgrade take?
It depends on scope. A simple battery upgrade might take a day, while a full system redesign with solar, inverter and battery installation could be 3–5 days or more.
We give you accurate timeframes once we've assessed your specific requirements and current setup.
Should I choose AGM or lithium batteries?
Lithium offers real advantages — lighter weight, longer lifespan (10+ years vs 3–5), faster charging, and you can use far more of the battery's capacity. It costs more up front.
AGM is more affordable initially and works well for occasional use. We'll help you choose based on your budget, how often you travel and your power needs. See RV battery upgrades.
Do I need solar panels?
Solar is highly worthwhile if you freedom camp or stay off-grid regularly — it keeps your batteries charged without a generator or mains power, for more independence and less noise.
How much you need depends on your daily consumption and battery capacity. We can size the right system, or you can start with our solar calculator.
What size inverter do I need?
It depends on what you want to run. A coffee machine or microwave might need 1000–2000 watts; a laptop or TV far less (100–300 watts). We also allow for surge power when appliances start up.
Most RVs suit inverters between 1000–3000 watts. We'll calculate your specific requirements — see RV inverter installation.
Will my electrical system need EWOF certification?
If your motorhome or caravan has a fixed 230V mains electrical system — one that connects to mains or campground power — it needs an EWOF (Electrical Warrant of Fitness). It's a legal requirement and must be completed by a registered electrician.
We provide EWOF certification and make sure all work meets the required AS/NZS 3001.2 standards.
Can you work on imported RVs?
Yes — we regularly work on imported motorhomes and caravans. Many are designed for different standards and need upgrades or modifications to run well here.
We can assess your imported RV's electrical system and recommend what's needed for safe, reliable operation in New Zealand, including 120V to 230V conversions.
How much does an electrical upgrade cost?
It varies with what you need. A basic battery upgrade might start around $1,500–$3,000, while a complete system with solar, lithium batteries and an inverter could be $8,000–$15,000 or more for larger setups.
