Trusted by Leading Brands
Premium home energy technology - installed by an established London electrical contractor.
SIGENERGY SIGENSTOR
More than a home battery.
SigenStor is Sigenergy's integrated home energy platform. Rather than combining a collection of unrelated components, the system brings the core parts of solar generation, battery storage and energy management into one modular ecosystem.
Sigenergy describes SigenStor as a 5-in-1 platform integrating a solar inverter, battery power conversion system, battery pack, energy management system and optional EV DC charging.
INSTALLED BY SWITCHED ON LONDON
Designed around the property - not around a box.
The equipment is only one part of a successful home energy installation.
We consider the available roof space, expected generation, household demand, battery capacity, existing electrical installation, cable routes, earthing, grid connection requirements, equipment location, backup requirements and future plans such as EV charging or a heat pump.
That engineering-led approach is particularly important in London, where space is often limited and properties rarely present a perfect blank canvas.
Build the system
One ecosystem. Configured around your home.
Sigen Energy Controller
The hybrid inverter / energy controller at the heart of the solar and storage system, managing energy conversion and system operation.
Sigen Battery
Modular stackable battery storage that allows capacity to be configured around the household's requirements and expanded where the selected product configuration allows.
Sigen Energy Gateway
For compatible designs requiring backup functionality and whole-home energy control during grid outages.
Sigen EV DC Charging Module
Optional DC-coupled EV charging within the Sigenergy ecosystem, with bidirectional / V2X capability subject to vehicle compatibility, standards and product support.
WHY SIGENERGY?
A premium platform that can grow with the home.
We like systems that are easy for the homeowner to understand, technically coherent for the installer and flexible enough to accommodate changing energy requirements.
SigenStor's modular architecture makes it particularly attractive for customers who want solar and battery storage today but may later add more storage, backup power or EV integration.
Integrated design
Solar, storage, energy management and compatible EV functionality are designed as one ecosystem rather than separate products from multiple manufacturers.
Modular storage
Stackable battery architecture allows the storage system to be configured around the application.
Smart energy management
Sigenergy's software platform can manage and optimise energy flows using household energy data and configured operating modes.
Outdoor-ready equipment
Current SigenStor product literature lists IP66 protection for the system, helping create more installation-location options where the design and manufacturer requirements allow.
Strong visual design
The finished equipment looks like premium home technology - particularly useful when plant cannot be hidden away in a large utility room.
SMARTER ENERGY MANAGEMENT
See where your energy is going.
The mySigen platform gives homeowners visibility of generation, storage, household consumption and grid interaction from one connected system.
Sigenergy also promotes AI-assisted energy planning and optimisation within the Sigen ecosystem. The website should describe this as intelligent energy management - not promise specific savings that cannot be guaranteed.
HOME BACKUP
Keep the house switched on when the grid isn't.
A standard grid-connected solar system normally shuts down when the electricity network fails.
A correctly designed Sigenergy installation can incorporate a compatible Sigen Energy Gateway so the battery and solar system can provide backup power during qualifying grid outages.
The backup design must be assessed around the property, supply arrangement, expected loads, available inverter and battery capacity and the circuits the customer wants supported.
WHY SWITCHED ON LONDON?
The system is smart. The installation still needs to be engineered properly.
Premium equipment does not compensate for poor design, inadequate protection or weak electrical workmanship.
Switched On London approaches Sigenergy projects as complete electrical installations. That means looking beyond the battery cabinet to the consumer unit, earthing, protective devices, AC and DC isolation, cable routes, monitoring, gateway arrangement, DNO requirements and the final commissioning and handover.
MCS certified
Solar and battery work completed within our applicable MCS scope and certification process.
NICEIC Approved Contractor
Electrical installation and compliance are core parts of the business.
DNO applications
We establish and manage the relevant G98/G99 connection route for the proposed system.
Complete installation
Solar PV, battery storage, gateway, EV charging and associated electrical upgrades can be coordinated by one contractor.
London experience
Designs account for the real constraints of London housing: tight plant spaces, difficult cable routes and multiple roof areas.
WORKMANSHIP
The technology gets the attention. The detail makes it work.

RECENT PROJECT · SOUTH WEST LONDON
A complete Sigenergy solar and battery installation on a complex London home.
This project used multiple available roof areas rather than relying on one large uninterrupted pitch.
The solar array was integrated with a Sigenergy SigenStor battery system and Energy Gateway, creating one connected home-energy installation designed around the property's electrical and spatial constraints.
Solar array
designed around usable roof areas.
Battery storage
designed around usable roof areas.
Energy Controller
designed around usable roof areas.
Gateway / backup
integration between grid, home, solar and storage.
DNO route
integration between grid, home, solar and storage.
