Sigenergy Gold Installer

SigenStor,
built to grow with you.

A modular battery system, sized to your home and expandable any time, all run from the mySigen app.

Start small, add more later

About 6kWh and 9kWh modules, up to six per tower.

Five products in one

Solar and battery inverters, battery, energy management and optional DC EV charging.

Works around your tariff

Charges and discharges around your usage, the weather and your tariff.

Backup in a power cut

With a Sigen Gateway fitted, the circuits we agree with you switch to battery without a break.

What it does

5 in one.

SigenStor stacks a solar inverter, a battery inverter, battery modules, an AI-powered energy management system and an optional DC EV charger into a single slim tower: one clean unit instead of a wall of boxes, built to grow.

  • AI-driven optimisation. Learns your usage, the weather forecast and your tariff to charge and discharge at the smartest times
  • Hybrid inverter range to suit every roof and consumption profile, single or three-phase
  • Safety first. LFP battery chemistry with five layers of battery protection

How it fits your home

Rated IP66, indoors or out.

The SigenStor tower is rated IP66: sealed against dust and protected against powerful jets of water. So an external wall suits it as well as a garage or utility room. We agree the position with you at design stage.

  • IP66 rated: dust-tight and protected against powerful water jets
  • Indoor or outdoor installation, including external walls
  • Grows in place: extra modules stack on the same tower
App control

Control it from the mySigen app.

A live energy-flow diagram of your whole system: solar, battery, home, grid and car. Deep controls for the people who want them, AI automation for those who don't.

  • AI mode optimises charging around the weather and your tariff
  • Dynamic tariffs supported natively: buy when prices dip, hold for peak hours
  • EV charging scheduled in the same app when the DC module is fitted
Every watt, accounted for
Honest assessment

mySigen app: the pros and cons.

What it does brilliantly

  • Exceptional detail: per-module battery data, live power flows and rich history
  • Granular manual control alongside an AI mode that optimises around weather and tariff prices
  • A strong fit for agile and time-of-use pricing

Worth knowing

  • More features means more to learn. Busier than Tesla's minimalist app
  • Sigenergy is a newer brand, founded by ex-Huawei energy leadership. A shorter track record than Tesla, albeit with rapid adoption
  • Vehicle integration needs the Sigen charger hardware

Add more later

Start small, stack more later.

You don't have to over-buy on day one. Start with what you need and stack another module later, or add a second tower for a bigger home.

Expanding SigenStor

  • Battery modules About 6kWh or 9kWh
  • Per tower Up to 6 modules, about 54kWh
  • More towers Two in parallel, with the Sigen Gateway SP-F

Backup

Power in a power cut.

Backup needs a Sigen Gateway. When the grid drops, it moves the circuits it backs up onto battery power without a break, as long as they draw no more than the system can supply, so most homes won't notice. Which circuits stay on depends on how your system is designed, and we agree that with you before installation.

  • No-break switchover: Sigenergy rates it at 0 ms when the backup load is within the system's rating
  • Configurable reserve, managed manually or by the AI around weather and tariffs
  • Unlocks parallel towers: run multiple SigenStor units as one larger system

Sigen Gateway SP-F

  • Role Grid isolation, metering & control
  • Switchover 0 ms, within the system's rated load
  • Backup coverage Whole home or selected circuits, by design
  • Battery expansion Parallel SigenStor towers
  • Metering Whole-home, live in mySigen
  • Installation At the incoming supply, indoor or outdoor
  • Warranty 5 years

Sigenergy FAQs

SigenStor questions, answered.

How much battery capacity should I start with?

It depends on your consumption and tariff. We size every system from your actual usage data.

Do I need the Sigen Gateway?

For backup during power cuts, or to run multiple battery towers in parallel, yes. For bill-saving solar storage alone, the core SigenStor tower is enough.

Is the DC EV charger worth it over a normal home charger?

If you drive a lot, yes. Up to 25kW DC is several times faster than a 7.4kW AC charger, and it can draw directly from solar and battery. If you only top up overnight, the AC option may be all you need. We'll model both against your mileage.

Is a newer brand a risk?

A fair question. Sigenergy has scaled globally at remarkable speed with strong engineering pedigree, and products carry a 10 year warranty (extendable to 15 years).
