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 — much like doing RV comparisons in Australia before settling on the right motorhome or camper setup. 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 — just as travellers rely on Campervan vs motorhome guides or a motorhome size comparison Australia before buying. — not just cars or marine. They should understand payload limits, space constraints, roof mounting, and the balance of solar input vs battery draw — the same level of detail travellers consider when looking at RV gearbox types compared Australia before purchasing.
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 — the same planning required for tackling the best motorhome routes in Tasmania.
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 — especially if you travel often during off peak RV camping Australia seasons.
5. Top Products to Include in Your Setup
Building a safe and efficient RV solar and electrical system isn’t just about picking any solar panel and battery. It’s about choosing quality components that work together seamlessly — ensuring your fridge stays cold, your lights stay on, and your batteries charge quickly and safely whether you’re parked or driving — no matter if you’re doing an Australian RV travel coast comparison between east and west.

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 also advise you on what to keep for RV journeys alongside your electrical essentials. They can help you size and spec your system correctly — and avoid costly rework later.
