SigEnergy SigenStor Installers
Every home is different. That’s why SigenStor is built to adapt to every energy scenario. Whether you just want to save on bills, add solar, charge an EV, or keep the lights on in a power cut, it’s ready for it all. One system, endless possibilities.
The 5-in-1 Energy System
Instead of separate boxes for each function, SigenStor combines five essential energy technologies into one sleek, scalable system:
Solar Inverter: Convert and manage your solar power.
Battery Storage: Store electricity for when you need it most.
EV DC Charger: Charge your electric car directly from solar or battery.
Energy Management System (EMS): AI-driven optimisation to cut bills.
Backup Power: Automatic switchover to keep your home running.
We love SigenStor because it’s the perfect balance of design, performance, and futureproofing and our customers love it because it makes their homes smarter, cleaner, and more independent.
Simple. Stackable. AI-Optimised.
This isn’t a box you’ll want to hide away. With its stylish front eagle-eye display and subtle side ambient lighting, SigenStor blends beautifully into modern homes. It’s technology that doesn’t just perform brilliantly, it looks the part too.
SigenStor learns how your home uses energy, automatically charging and discharging to save you money without you lifting a finger.
Not sure how much storage you need? Start small and add more over time. From 10 kWh to 48 kWh, SigenStor evolves as your energy needs change.
Safety is built in at every level. From advanced thermal protection to smart sensors and an integrated fire extinguisher, you can rest easy knowing your home is protected.
Even Better With Solar
Pair your SigenStor installation with solar panels, and you’ll have the ultimate energy independence setup:
Generate your own clean electricity.
Store excess energy for evening use.
Charge your EV directly from the sun.
Keep the lights on during power cuts.
Apex Doma are both solar installers and Sigenergy battery installers, meaning we design the entire system for maximum performance.
Not ready for solar yet? No problem.
SigenStor can be used as a standalone battery, charging on cheap overnight tariffs and discharging when rates peak. It’s the easiest way to cut costs and increase independence, and it’s solar-ready for when you want to expand.
Two-Way EV Charging
Unlike traditional chargers, SigenStor’s bi-directional EV charging unlocks new possibilities. You can power your home directly from your EV (V2H) or export to the grid and get paid (V2G).
Your EV is no longer just transport, it becomes part of your home energy solution.
