SIGENERGY
Modular Energy Storage
for Industry & Business
Pioneering modular AC-coupled energy storage technology — scalable systems from kWh to MWh for industrial facilities, logistics centres, agricultural operations and large commercial premises.
SIGENERGY
Modular Energy Storage
SIGENERGY (SigenEnergy Technology Co., Ltd.) is one of the most innovative energy storage companies in the world — founded in 2021 with a focus on modular, AC-coupled architecture that is redefining the industry. Each module includes its own integrated inverter and battery, creating a self-contained, independent energy cell.
The result is a system that scales from a few kWh to hundreds of kWh or MWh — without replacing existing equipment, without a single point of failure, and with guaranteed compatibility with any existing solar installation. The ideal solution for industry, logistics, agricultural operations and large businesses.
The Advantage of Modular Architecture
Start
Deploy the number of modules that matches your current energy needs. Each module is fully independent and immediately operational — no delays, no complexity.
Expand
As your business grows or energy demands increase, simply add new modules. Nothing is replaced — expansion is literally plug-and-play.
Redundancy
If one module fails, all others continue operating normally. There is no single point of failure — ideal for mission-critical industrial applications.
What is DC Coupling and how does it differ from AC Coupling?
In DC Coupling, the battery connects directly to the system’s DC bus — before the inverter. Solar energy transfers straight from the panels to the battery with no intermediate DC→AC conversion, resulting in losses below 2%. In AC Coupling, the battery connects to the AC grid — easier to retrofit but with slightly higher conversion losses. Iliatoras has implemented both topologies based on each project’s specific requirements.
“Every module operates independently —
there is no single point of failure”
SIGENERGY’s modular architecture ensures continuous operation even if one or more modules fail

Industrial & Commercial Applications
A versatile solution for every sector with significant energy requirements
Industrial Facilities
Factories, production plants and heavy industry — off-peak load shifting, demand charge reduction and guaranteed uninterrupted operation.
Logistics Centres
Warehouses and distribution centres operating 24/7 — utilise off-peak energy for EV charging and reduce operational costs.
Agricultural Operations
Pumping stations, greenhouses, cold storage — energy independence for remote agricultural and livestock facilities with no grid dependency.
Hotels & Tourism
Tourist accommodation, resorts and hotel properties — eliminate peak demand charges, ensure uninterrupted power supply and optimise energy costs.
Manufacturing & Workshops
Small and medium manufacturing units with seasonal or variable consumption — the SIGENERGY modular system adapts precisely to the needs of every season.
Infrastructure & Remote Sites
Off-grid installations, telecom towers and engineering projects in remote locations — reliable power without grid connection.
Benefits for Your Business
SIGENERGY delivers tangible, measurable results from day one
Reduced Operating Costs
Store energy during off-peak hours and use it when electricity is expensive. Eliminate demand charges and reduce your electricity bill by 20–40%.
Energy Independence
Maximise self-consumption of your solar generation. Instead of selling surplus at low feed-in rates, store it and power your business with your own energy.
Backup Power
Automatic supply to critical loads during outages. For production lines, refrigeration systems and security infrastructure — zero downtime, zero losses.
Smart Energy Management
Real-time monitoring from your smartphone — live energy dashboard, alerts, savings reports. Full visibility and control over your business energy profile, anywhere.

Frequently Asked Questions
Everything you need to know about SIGENERGY energy storage
Can SIGENERGY be integrated with an existing solar installation?
Yes — the AC-coupled technology connects on the AC side of the grid, making it compatible with any existing solar system regardless of inverter brand. There is no need to replace the existing inverter — SIGENERGY integrates seamlessly without disrupting the operation of the installed system.
How long does a SIGENERGY installation take?
The physical installation takes 3–7 days depending on system size. The modular design significantly accelerates installation compared to traditional systems. The full process — from feasibility study and grid connection through to commissioning — typically completes in 4–8 weeks. Contact us for a detailed project timeline.
What is AC-coupled technology?
AC coupling connects the storage system to the electrical network at the alternating current (AC) level — like a standard power outlet — rather than inside the inverter at the direct current (DC) level. This means full compatibility with virtually any existing solar system, as well as the ability to operate as standalone storage even without solar panels.
How scalable is the SIGENERGY system?
From a few kWh to hundreds of kWh or MWh — with no upper limit. Modules can be added at any time without replacing existing equipment. This is true plug-and-play expansion: each new module connects and integrates automatically into the system.
What certifications does SIGENERGY hold?
SIGENERGY holds CE certification for the European market as well as safety certifications for LFP batteries. Iliatoras Photovoltaic, as a certified local installer, ensures full compliance with Greek and European legislation on every installation.
