Our tailored service is built around your needs and your expectations, with installation that fits around your vehicle and space. It's your own independence, the exact way you need it to be.
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.
