RV Solar Setup for Full-Time Living: Complete Guide
Full-time RV living punishes weak gear. I learned that the hard way at my rural NSW site when I committed $1,850 to a proper install: a 400W Renogy panel, a Victron BlueSolar 150/100 MPPT charge controller, and a 200Ah LiFePO4 battery. The cheap substitute I tried first died after three months, fried during a heatwave that knocked the controller out and forced the generator back into service to keep the fridge cold. The replacement Victron set me back another $140, bolted in with my Makita 18V driver. Even with the gear sorted, the National Electrical Safety Code still applies, and my local council wanted paperwork sorted before I touched the grid. Sort the approvals first, then start mounting rails.

My $1,850 Solar Setup, the Heatwave That Fried the Controller, and the NSW Council Approval That Followed
My van's been my full-time home for years, and I needed power I could trust. $1,850 set me up—panels, controller, battery bank, all the wiring—running lights, a fridge and a laptop without a generator. Here's exactly what I bought, how I fitted it, and the safety checks I don't skip.
My Full-Time Solar Setup: What Works, What Fried and the Council Permit Process
- Cost Savings: Solar reduces fuel and electricity costs, saving hundreds annually.
- Environmental Impact: Zero emissions and reduced reliance on fossil fuels.
- Freedom and Flexibility: Power your RV anywhere, even off-grid.
- Low Maintenance: Modern solar systems require minimal upkeep.
What $1,850 Bought: The Solar Rig Powering My Full-Time RV
Solar Panels
Solar panels convert sunlight into electricity. Choose based on your energy needs and roof space.
Charge Controller
Regulates voltage from panels to batteries, preventing overcharging.
Battery Bank
Stores energy for use when sunlight is unavailable. Lithium-ion batteries are popular for their longevity.
Inverter
Converts DC power from batteries to AC for appliances.
Roof Mounts, Rails and Sealant
Secures panels to your RV roof. Ensure durability and weather resistance.

Mounting the Panels onto the Caravan Roof
Calculating my actual daily watt-hour draw from the appliances I run
Sizing and Installation
Calculate daily energy consumption using a watt meter. Example: 100W fridge + 150W TV = 250Wh/day.
The $1,850 Component List Wired Into My Van
I base my picks for panels, batteries and inverters on the calculations I’ve already done, then I stick to the cost‑effective tiers I outlined earlier.
Mounting the Panels to the Van Roof
Mount panels securely on your RV roof. Ensure proper tilt for optimal sunlight exposure.
How I wire the charge controller
Wire panels to the charge controller, then connect to the battery bank.
5. Add Inverter
Link the battery bank to the inverter to convert DC to AC power for your appliances.
Twelve Hours Under Real Load
Use a multimeter to verify voltage levels and ensure all connections are safe.
The Heatwave That Fried My Solar Controller and the NSW Council Letter That Came After
- Electrical Hazards: Always disconnect the RV’s main power before working on the system.
- Proper Wiring: Use UV-resistant cables and avoid overloading circuits.
- Fire Risk: Ensure all components are certified and installed according to local codes.
- Professional Help: For complex installations, consult a licensed electrician.
Questions I Get Asked About Living Full-Time on Solar
Sizing the Array to My Real Daily Watt-Hour Load
Calculate your daily energy use and add a 20-30% buffer. A 100W panel can generate ~15-20Wh/day.
Wiring the Panels Myself: The Heatwave That Fried My Controller and the Council Forms I Wish I'd Known About
Yes, for basic setups. However, complex installations require professional expertise.
Heatwave, fried controller, and the NSW council approval: the real test of off‑grid solar
High-quality panels last 25+ years, while batteries may need replacement every 5-10 years.
My Post-Install Routine: Panel Wipes, Torque Checks, Inverter Reads
Regularly clean panels and check connections. Lithium batteries require minimal upkeep.
Sharing the Load Between Solar, Generator and Shore Power
Yes, integrate with generators or shore power for backup during cloudy days.
My $1,850 Solar Install: The Heatwave, the Fried Controller, and the NSW Council Approval
Years of running solar on the rig taught me what actually matters: pick the right budget tier, size the panels, regulator and inverter to your real load, and don't muck the wiring. Fuses on every circuit, sound earthing, and if the job's beyond your skill set, bring in a licensed auto-electrician—no exceptions. Done right, the system runs the essentials day in, day out without me hovering over the batteries.
When the Job Goes Past the Battery Bank
While many off-grid projects are achievable as DIY, certain situations require licensed professionals:
- Electrical work beyond basic replacements — always use a licensed electrician
- Structural modifications to buildings or load-bearing elements
- Gas line installations or modifications
- Roof penetrations for solar panel mounting
- Anything involving high voltage or battery bank connections
- Water rights or council approvals that require professional assessment
Safety should always come first. When in doubt, consult a licensed tradesperson.
