Why build a bespoke system?

Bespoke systems are ideal if you're looking to build something specific to your own use case. Maybe you're looking to travel for months on end or maybe you have specific devices that require higher output and a bigger electrical system. Whatever the need we're on hand to help get you the system that will power your independence.

You want to run high powered appliances

If you're planning on running power heavy appliances then a bespoke system should be considered to ensure you're not draining power rapidly. When it comes to off-grid, the more power something uses, the more power you'll need.

You work remotely with heavy daily use

If you're one of those who works late into the night, a bespoke system might be better than one of our packages. The more power you use the more we need to plan so it's worth speaking to us to discuss exactly what your working needs are.

Frequently Asked Questions

Got more off-grid questions? We're here to answer them.

What makes bespoke different?

Bespoke systems are tailored exactly to your needs. Our packages are great for most use cases but sometimes our clients need more control over their system, that's where bespoke design comes in.

How long does installation take?

It varies depending on the system we design, anywhere from 1-2 months is reasonable but it could take longer. We'll be able to advise during our initital chat. If you're looking to go off-grid fast, check out our weekender package which can be installed in 2 weeks.

Can I upgrade later?

It most cases yes, however we advise you consider how you'll use the system in the future when building a bespoke system. This helps us plan for eventual use cases and reduce upgrade costs down the line.

What if I already have electrical work?

We assess existing installations and integrate them into your bespoke system where it makes sense. Sometimes we work around what's there, sometimes we recommend starting fresh for safety and reliability.

How do you determine system size?

We start by listing every device you'll run, how many hours daily, and your travel duration. From there we calculate battery capacity and solar generation needed to keep you comfortable off-grid.

Do you offer long term support?

Yes, every system we install is backed by our Aftercare service. If you have any problems we'll diagnose them for you and advise on next steps.

What about winter travel?

It's a common question we get asked. Winters are difficult for off-gridders but we designed systems that can handle the seasons.

What vehicles do you work with?

We work with all types of campervans, van conversions motorhomes and more. We've seen it all and built in tight spaces and huge areas. give us a call and we'll discuss how to best fit an off-grid system into your vehicle.
