FAQ

Understanding how RV solar actually works

Most caravans and motorhomes come with a basic setup from the factory, usually:

A single 100Ah 12V battery and sometimes a small solar panel (often 40W–150W depending on model and year)

This setup is fine for short stays at powered sites or light off-grid use — typically around 1–3 days depending on how you travel.

But here’s the important part most people don’t realise:

Solar panels don’t run your RV — they recharge your battery.
Your battery is what actually powers everything in your 12V system.

That includes your:

Lights, water pump, fridge (in many cases), toilet systems, charging devices and accessories

So if your battery capacity or solar input is too small, you simply run out of stored power.

Why most factory setups fall short

Factory solar systems are designed for light use, not extended off-grid travel.

What usually limits people is:

  • not enough battery capacity
  • not enough solar to recharge during the day
  • increasing power use (fridge, coffee machines, Starlink, laptops, etc.)

The result is the same:

You either have to plug in more often, or cut your trip short.

What a properly designed off-grid system changes

A correctly sized solar and battery setup allows you to:

  • stay off-grid for longer without worrying about power
  • run modern appliances comfortably
  • reduce reliance on powered campsites
  • travel with more freedom and flexibility
  • increases battery life

But the right setup depends entirely on how you travel.

To design the right system, we look at:

  • How many nights you want to stay off-grid
  • What appliances you run daily (fridge, coffee machine, Starlink, etc.)
  • Whether you already have solar or batteries installed
  • Roof space available for additional solar panels
  • How often and where you travel

Every setup is different — there’s no one-size-fits-all system that works properly for everyone.

Can you upgrade your existing system?

In most cases, yes.

Depending on your current setup, we can often:

  • add additional solar panels
  • upgrade to lithium batteries
  • increase charging capacity
  • improve system efficiency and reliability

Or design a complete off-grid system from scratch.

Not sure what you need?

That’s completely normal — most RV owners aren’t.

If you’re unsure what size system suits your travel style, just get in touch and tell us how you use your Caravan or motorhome.

We’ll point you in the right direction and recommend a setup that actually fits how you travel.

Get off-grid with confidence

Freedom camping is far more enjoyable when your power system just works.

If you want a reliable off-grid setup for your caravan or motorhome, we can help you design and install a system that suits your travel style — not just a generic package.
