V2X FAQs.

V2X technology is new to many people. Here are some of the most common questions from EV owners.

• 01 What is V2X?

  V2X stands for Vehicle to Everything. It means your EV can send power back out — to your home (V2H), the grid (V2G) or other devices (V2L). It turns your car into a power station on wheels.

• 02 Which EVs are compatible with V2X?

  Not every EV supports bidirectional charging yet. We've tested and verified models like the Polestar 4 and Volvo EX90 as fully compatible, with more added every month. Check our full compatibility list or bring your EV to the demo centre and we'll check it together.

• 03 How much power can my EV supply?

  It depends on your EV's battery capacity, charger and your home's energy needs. On our tested vehicles we've seen up to 10.2 kW of V2H output — enough to power an average home for a day or more from a full battery.

• 04 Will using V2X drain my car battery?

  Using V2X does add extra charge-discharge cycles, but modern EV batteries and management systems are designed to handle this efficiently, with minimal extra degradation. You stay in control of how much charge is reserved for driving.

• 05 Do I need solar panels to use V2X?

  No — V2X works with or without solar. Solar simply gives you free energy to store in your EV or battery first, maximising your savings. Without solar, V2X still lets you charge when electricity is cheap and use that stored power later.

• 06 Is V2X safe for my EV and my home?

  Yes. Every installation is built on proven Sigenergy technology and follows UK wiring and grid-connection regulations. We test every system in real conditions at our own demo centre before recommending it to you.

• 07 How much does a V2X system cost?

  Cost depends on your home, your EV and which capabilities you want (V2H backup, V2G export, or both). We provide honest, no-obligation quotes after a free survey — get in touch for a personalised price.

• 08 Can I earn money with V2G?

  Yes. With Vehicle-to-Grid, you can export surplus energy from your EV back to the grid and get paid or credited for it — effectively turning your car's downtime into an income source, while helping balance the wider grid.

• 09 Where is the V2X Solutions demo centre?

  Near Cardigan, Ceredigion, West Wales (postcode area SA43), at a real home fitted with the V2X system. Visits are by appointment, Monday to Saturday, up to 3 people per visit — full directions are sent after booking.

• 10 Can I see a demonstration without visiting in person?

  Yes. Our Watch an EV Power a Real Home page has a live demonstration video plus real-time power-flow data from an actual Polestar 4 powering our West Wales demo home. Visiting in person also lets you bring your own EV and test it live.
