How to Choose the Right RV Solar & Electrical Provider

Choosing the right solar and electrical expert for your RV is just as important as choosing the gear itself. Even the best batteries or panels can underperform — or even fail — if installed incorrectly, undersized, or without proper safety precautions. Your provider should do more than install parts — they should understand your travel lifestyle and design a system that supports it with reliability and confidence.

Here’s what to look for when choosing your installer or supplier:

1. Experience with RVs and Off-Grid Systems

Not all auto electricians are RV experts. Choose a provider who specialises in RV, van, or off-road 12V setups — not just cars or marine. They should understand payload limits, space constraints, roof mounting, and the balance of solar input vs battery draw.

2. Licensing and Compliance

Make sure your installer:

  • Is a licensed auto electrician and/or electrical contractor

  • Provides a Certificate of Compliance for 240V installations

  • Installs to AS/NZS 3000 & 3001 standards

  • Uses quality fusing, cable protection, and circuit isolation

3. Brand Knowledge and Integration

Look for providers who work regularly with:

  • REDARC, Enerdrive, Victron, Projecta, BMPRO

  • Lithium battery manufacturers (LiFePO₄)

  • Quality solar panel brands with Australian support
    They should be able to explain how all the components will work together, not just “fit” them.

4. Personalised System Design

The best providers won’t just install what’s trendy — they’ll ask:

  • How many days off-grid do you want to stay?

  • What appliances do you want to run (fridge, laptop, air con)?

  • How much weight and space can your RV handle?

  • Do you already have components that need integrating or upgrading?

5. Support and Troubleshooting

Check reviews for how the provider handles:

  • Warranty claims or equipment faults

  • Rewiring or correcting failed DIY jobs

  • Technical support after installation

6. Mobile vs Workshop-Based Installers

  • Mobile installers: convenient, come to your home or campsite, but may have limits on space or tools

  • Workshop installs: better for complex fit-outs, testing, and multi-day work — but may require booking weeks in advance

Final Tip: Don’t Choose on Price Alone

The cheapest quote might mean:

  • Undersized cables (causing voltage drop)

  • No fuse protection (fire risk)

  • Poor workmanship that voids your warranty

  • Lack of service if something goes wrong

Investing in a skilled, reputable provider pays for itself in safety, reliability, and long-term performance.

7. Common Mistakes in DIY or Cheap Installs

While DIY RV solar and electrical setups can save money upfront, they often lead to costly problems down the track — especially if done without proper planning, tools, or understanding of safe system design. Even some cheap professional installs cut corners to keep costs low, resulting in poor performance, safety hazards, or component failure.

Here are the most common mistakes to avoid:

1. Undersized Wiring

  • One of the most dangerous (and common) errors

  • Thin cables cause voltage drop, poor charging, and even overheating or fire

  • Rule of thumb: always overspec your cable size — especially for high-amperage devices like inverters and DC–DC chargers

2. No Fuse Protection or Isolators

  • Every major circuit (battery to charger, charger to inverter, etc.) must be fused

  • Lack of fuses = high risk of electrical fire

  • Battery isolators should also be included to disconnect power when needed

3. Incompatible Battery Chemistry

  • Lithium batteries require specific chargers and regulators

  • Using AGM settings on lithium banks can damage the battery or void warranty

  • Some older solar regulators and DC–DC chargers are not lithium-compatible

4. Poor Solar Panel Placement

  • Installing panels where they’ll be shaded by roof vents, aircons, or awnings

  • Shading even a small part of one panel can reduce system performance by 50%+

  • Flat-mounting without tilt options reduces efficiency, especially in winter

5. Inverter Overload or Misuse

  • Using a 1,000W inverter to run a 1,500W appliance will cause shutdown or system strain

  • Not understanding pure sine vs modified sine wave — some devices won’t run at all on modified inverters

  • Forgetting to fuse inverter input = fire risk

6. No Power Usage Planning

  • Installing random components without calculating actual usage (amps per day)

  • Overloading systems or draining batteries too fast due to unrealistic expectations

  • Not allowing for expansion or future upgrades

7. Mixing Low-Quality Components

  • Combining cheap eBay panels, no-name lithium batteries, and poorly crimped wiring leads to premature failure

  • Lack of after-sales support or warranty coverage

  • Inferior gear may not comply with Australian safety standards

Pro Tip:

Even if you’re doing a DIY install, consult with a reputable supplier like DIY Touring or Solar 4 RVs. They can help you size and spec your system correctly — and avoid costly rework later.

FAQs about ydney's RV travel guide

How much solar do I need for my RV in Australia?

The amount of solar you need depends on your daily energy consumption, how many days you plan to stay off-grid, and what appliances you intend to run. As a general rule:

  • 200–300W: Suitable for weekenders running lights, USB charging, and a 12V fridge

  • 400–600W: Great for full-time travel with a fridge, lights, laptops, fans, and occasional 240V use

  • 700W–1,200W+: Required for high-demand setups running inverters, induction cooktops, air cons, or CPAP machines

You’ll also need to consider:

  • Battery size (to store solar energy for nights and cloudy days)

  • Regulator type (MPPT is more efficient than PWM)

  • Panel mounting angle and shading (can reduce output dramatically)

  • Your average location (northern Australia gets more sun than Tasmania)

To calculate your needs, add up the daily amp-hours (Ah) each device uses and multiply by the number of hours used. Then ensure your solar system can replenish at least 80–100% of that each day. A provider can help you size your system correctly — but for most Aussie travellers, 400–600W of solar and a 200Ah lithium battery bank is a great all-rounder.

Lithium (LiFePO₄) is widely considered the best battery type for RVs today, especially for off-grid travel. Compared to traditional AGM (Absorbent Glass Mat) batteries, lithium offers:

  • More usable capacity: 90–100% of total capacity (vs 50% in AGM)

  • Faster charging: 2–4 hours (vs 6–12 for AGM)

  • Longer lifespan: 2,000–5,000+ cycles (vs 500–1,000)

  • Lighter weight: 10–15kg for a 100Ah lithium (vs 30–35kg for AGM)

  • Higher efficiency: Less voltage drop, better performance in high-load applications

However, lithium is more expensive upfront and requires a compatible charging system (DC–DC charger and solar regulator must be lithium-safe). AGMs are still a good option for those on a budget, for short trips, or when upgrading part of an old system.

If you’re building a system for full-time travel, heavy appliance use, or long off-grid stays — lithium is worth the investment.

Professional RV solar installation in Australia typically ranges from $1,500 to over $10,000, depending on system size, vehicle type, and gear quality.

Typical price breakdowns:

  • Basic Setup ($1,500–$2,500): 200–300W solar, 100Ah AGM, MPPT controller

  • Mid-Tier ($3,000–$6,000): 400–600W solar, 200Ah lithium, DC–DC charger, inverter

  • Premium Setup ($7,000–$10,000+): 1,000W+ solar, 300–400Ah lithium, full Victron/Enerdrive integration, inverter-charger, monitoring system

What affects cost:

  • Type and number of components (battery, panel wattage, inverter size)

  • Labour hours (custom installs vs simple setups)

  • Roof access and mounting complexity

  • 240V compliance work (legally must be done by an electrician)

  • Mobile vs in-workshop install

Going cheap may seem attractive, but poorly installed or undersized systems often lead to early upgrades, electrical faults, or even safety hazards. Investing in a quality install gives you long-term performance and support.

Yes, many RV owners choose to install solar panels themselves — especially for 12V-only setups (solar to battery via regulator). However, there are important safety and legal considerations.

You can DIY if:

  • The system is under 50V DC and doesn’t include 240V wiring

  • You use a fused solar regulator and proper cable sizes

  • You know how to secure roof panels and seal wiring entries

  • You understand basic battery safety (avoiding overcharge/discharge)

You cannot legally DIY:

  • 240V AC circuits (e.g. inverter output to wall outlets)

  • Installations involving RCDs, circuit breakers, or mains input

  • Shore power connections or full switchboards

Recommended approach:

  • Use DIY Touring or Solar 4 RVs kits for safe, simplified setups

  • Hire a qualified auto sparky for anything beyond basic solar + battery

  • For anything involving AC power, always use a licensed electrician

A hybrid approach (DIY solar + pro-installed battery/inverter) is also common and safe when done with expert guidance.

The right inverter size depends on what 240V appliances you plan to run. Inverters are rated in watts (W) — choose a model that matches or exceeds the combined power draw of everything you’ll be running at once.

Common inverter sizes:

  • 300–600W: Lights, phone chargers, laptops

  • 1,000–1,500W: TV, kettle, power tools, low-draw appliances

  • 2,000–3,000W: Microwaves, induction cooktops, air cons, hairdryers

General tips:

  • Always choose a pure sine wave inverter — they’re safe for all devices

  • Consider surge ratings — many appliances use 2–3x their normal wattage on startup

  • You’ll need adequate batteries to run a large inverter (e.g. 2 x 100Ah lithium for 2,000W+)

  • Inverters require heavy cabling, proper fusing, and ventilation

If unsure, speak with your installer. They’ll match your inverter to your battery bank, solar system, and appliance needs to avoid overload or early battery damage.

In Australia, 240V AC systems in caravans and RVs must comply with AS/NZS 3000 & 3001 electrical standards. If your RV plugs into mains power or has a 240V inverter output, it must be installed by a licensed electrician and should come with a Certificate of Electrical Safety (COC).

Key compliance features:

  • RCD (safety switch) installed on all AC circuits

  • Earth bonding to chassis where required

  • Correct circuit breakers and wiring methods

  • Weatherproof exterior inlets/outlets

  • Labels indicating safety and compliance

12V DC systems (solar, battery, lights) don’t require legal certification but should still be:

  • Properly fused

  • Wired with suitable cable gauge

  • Installed to manufacturer specs

  • Tested for voltage drop and safe isolation

If your RV was built before 2010 or had DIY electrical work, it’s worth having it inspected. Many insurers won’t cover electrical faults or fire damage if your setup is non-compliant.

Absolutely — especially if your current system is unreliable, underpowered, or ageing. Technology has advanced dramatically in recent years, making today’s lithium batteries, solar panels, and charging systems lighter, faster, and more efficient.

Reasons to upgrade:

  • Switching from AGM to lithium cuts weight and boosts usable power

  • Adding solar reduces generator/mains dependence

  • Installing a DC–DC charger ensures proper charging from your vehicle

  • Inverters let you use 240V gear anywhere, anytime

  • Smart monitors help you track power and avoid battery damage

Older systems often lack fuse protection, have worn or corroded cabling, and use inefficient solar regulators. An upgrade can improve performance, eliminate safety risks, and unlock the full potential of off-grid living.

Even partial upgrades — like adding solar to an existing AGM system or upgrading your DC–DC charger — can make a huge difference.
