Sigenergy Bi-Directional Charger Installation
DC-powered EV charging, built to work seamlessly with solar, battery storage and your entire home energy system.
Sigenergy
Bi-Directional
EV Charger Price
The Sigenergy 12kW bi-directional EV charger is available from £1,849 when installed as part of a new Sigenergy system.
If you already have a Sigenergy system and would like the charger added retrospectively, the cost is £1,999. This is because the existing system needs to be safely opened, adjusted and reconfigured to allow the charger to be added properly.
Unlike a standard EV charger, the Sigenergy bi-directional charger is designed to work as part of the wider SigenStor ecosystem, allowing your electric vehicle to integrate more closely with your home energy setup.
Why choose Sigenergy?
The Sigenergy SigenStor EV DC Charging Module is not a typical home EV charger. It’s a DC-coupled charging solution, designed to sit inside a wider energy ecosystem, connecting solar, battery storage and your vehicle into one intelligent system.
Unlike standard AC chargers, which rely on your vehicle’s onboard inverter, the SigenStor module delivers power directly via DC. This reduces conversion losses and allows faster, more efficient charging.
Sigenergy positions this as a central connection point between your EV and your home, enabling direct solar charging and future-ready energy flexibility.
For homeowners looking to future-proof their setup, it’s a fundamentally different approach to EV charging.
Sigenergy SigenStor EV DC Charging Module Installation
Our Sigenergy EV charging installations are designed around the full energy system, not just the charger itself.
Because the SigenStor EV module is built to work with the wider Sigenergy ecosystem, including the Sigen Energy Controller, inverter and battery storage, installation requires proper system design from the outset.
We start with a detailed site assessment, looking at your electrical supply, charger location, solar potential and whether battery storage is included. From there, we design a system that ensures the EV charger works seamlessly with the rest of your home energy setup.
Installation includes full system integration, commissioning and setup within the mySigen app, so you can monitor and control everything from day one.
How Sigenergy EV Charging Works
The key difference with Sigenergy is how the system is designed.
Traditional EV chargers pull AC power from the grid and rely on your car to convert it. The SigenStor system works differently, it uses a DC-coupled architecture, allowing energy to flow directly from solar panels or battery storage into your EV.
This enables:
- Faster charging
- Higher efficiency
- Direct solar utilisation
- Future bi-directional capability
- It also allows the system to act as part of a wider home energy network, where your EV, battery and solar all work together.
Sigenergy highlights this as enabling “100% green power charging” and future V2H/V2G functionality.
Sigenergy SigenStor EV DC Charging Module Benefits
Direct DC Charging (More Efficient Than AC)
The SigenStor charger uses a DC-to-DC connection, meaning energy flows directly from solar or battery to your EV, avoiding unnecessary conversion losses and improving efficiency.
Up to 12kW Bi-Directional Charging
The 12kW model provides stable, high-performance charging and supports bi-directional energy flow, meaning power can move both to and from your vehicle.
Charge Your EV with Solar
The system allows EV charging using 100% solar energy, prioritising surplus generation where available and reducing reliance on the grid.
Smart App Control (mySigen)
Monitor charging, schedule sessions and optimise energy usage through the mySigen app, integrating EV charging into your full home energy strategy.
