Off-grid power to explore everywhere.
Our most powerful off-grid system lets you live off-grid indefinitely, travel internationally and explore the world at your own pace, all while enjoying the comforts of home.
Designed for long-stay travel and full-time vehicle life, our Wanderer package packs the power needed to live comfortably off-grid for extended periods whilst you cook, work, relax and run your van exactly how you want. With high-capacity lithium, strong inverter output and expanded solar generation included, you can stay off-grid longer without relying on campsites so you’re free to travel further and settle wherever feels right.
Compatible with larger touring vehicles and motorhomes
Stay off-grid indefinitely with 10+ days power.
Enjoy all your home comforts without worrying about losing charge.
Support for international travel so you can explore the world.
Live fully off-grid, for the long haul.
Long trips shouldn’t mean watching your battery or planning your next hookup. Cook proper meals. Run your heating. Work, relax and live normally. The Wanderer delivers high-capacity, stable 230V power designed for extended touring, full-time travel and serious off-grid life.
Cross borders, stay powered.
Long-distance touring means crossing borders, changing climates and staying off-grid for longer. The Wanderer delivers the capacity and charging performance needed to keep your heating, refrigeration, appliances and daily essentials running reliably, so you can travel across the UK, Europe and beyond without planning your next hookup.
ASTT assistance, wherever you travel
Long trips mean you can’t always return to the workshop if something needs checking. The Wanderer includes remote system monitoring that allows our engineers to review performance, battery status and charging behaviour from anywhere, helping diagnose issues faster and keep your journey moving without unnecessary disruption.

Frequently Asked Questions
Everything else you need to know about our Wanderer Package
The Weekender is designed for typical work week use. It comfortably lets you work for 5 days off-grid under normal load. Power users may only get up to 3 days depending on weather conditions and overall power use. We'll help you understand the exact time off-grid during our initial chat.
Yes. The Worker is installed using modular components, allowing future upgrades such as additional battery capacity, solar expansion or higher inverter capability if travel needs change.
Components come with manufacturer warranties. Our installation workmanship is backed by our support commitment. We'll discuss specifics when you enquire.
ASTT will review your vehicle, travel style and appliance needs before confirming any booking. If a different package or bespoke system would suit better, this will be recommended.
Solar is designed as support, not the only recharge source. The system also recharges while driving and can be topped up via shore power when available, so poor weather does not prevent normal weekend use.
No. Every system includes a full handover explaining how to monitor power, recharge correctly and operate safely. The goal is confidence from day one, not technical complexity.
We can discuss options when you enquire. Every situation is different, and we're happy to explore what works for you.
Health checks cover battery condition, solar performance, and system safety. We identify issues early and recommend upgrades before problems start.
