Sigenergy SigenStor Battery Storage

 Store Overnight low cost electricity and reduce your heating and cooling costs!

The SigenStor is essentially a microgrid controller disguised as home battery storage. It doesn’t just store energy, it orchestrates generation, storage, consumption, and vehicle charging as one integrated system.

 

Battery Storage for the Home

Battery storage for the home, a tall, sleek tower that is installed in a garage or utility room and acts as the brain, heart, and muscles of your home’s electricity.

What Sigenergy Battery Storage Does

SigenStor battery storage captures energy from the grid during low tariff times and stores it. When the sun goes down or during a power cut, your house runs off the stored power.

This system reduces heating and cooling costs.

EV Charging

Charge your EV directly from the sun or battery, no need for a separate wallbox.

Five in One

SigenStor includes five elements in one box: inverter, battery, car charger, backup system, monitoring app, you get one stackable tower that manages your electricity and reports via an app on your phone.

SigenStor: It’s Not Just a Battery

The SigenStor integrates five distinct energy systems into one modular platform:

    • Hybrid Inverter | Converts DC to AC for your house.

    • Battery PCS (Power Conversion System) | Manages charging/discharging, DC/AC conversion.

    • Battery Packs | Energy storage modules using EV-grade LiFePO₄ cells.

    • EMS (Energy Management System) | AI-driven controller optimizing energy flows.

    • EV DC Charger (optional) | 25kW bi-directional DC fast charging module.

Why the DC Bus Matters

Direct DC coupling eliminates multiple conversion losses. e.g. when charging your EV, it can bypass AC conversion entirely – solar DC to battery DC to EV DC. That’s 95% efficiency vs. 75-80% for traditional AC-coupled systems.

The SigenStor Battery Storage Tech

Chemistry: Lithium Iron Phosphate (LiFePO₄ or LFP) – safer, longer-lasting than standard lithium-ion.
Cell grade: EV-grade 280Ah or 314Ah prismatic cells (same stuff in electric cars).
Modularity: 5kWh or 8kWh modules, stackable (max 6 modules = 48kWh).
Depth of discharge: 100% (you can use the full capacity).
Cycle life: 6,000+ cycles at 100% DoD.
Active balancing: Smart optimizer per battery pack allows mixing new/old modules.

Stackable Design

Unlike traditional wall-mounted batteries, SigenStor uses self-guiding pin connectors. Modules physically stack and automatically connect without complex DC wiring.

Bi-Directional Capability

With the EVDC module, your car becomes part of the system:
V2H (Vehicle-to-Home): Power your house from your car during outages.
V2G (Vehicle-to-Grid): Sell stored car energy back to grid (where supported).
