Sigenergy Product Range – Which Energy Storage System Fits Your Project?

Sigenergy develops several distinct technology platforms. Understanding their differences is important for system specification and procurement.

The product families are designed for different applications, and not every combination is interchangeable.

A residential SigenStor installation should not be designed using the same component assumptions as a commercial SigenStack system.

For professional buyers, selecting the correct architecture early reduces the risk of ordering incompatible equipment, additional accessories or incorrectly sized battery storage.

Sigenergy SigenStor – Modular 5-in-1 Solar Energy Storage System

The Sigenergy SigenStor is the manufacturer’s flagship integrated energy storage platform.

SigenStor is designed to bring together five energy functions within one coordinated system:

1. Solar PV inverter
2. Battery Power Conversion System (PCS)
3. LiFePO4 battery storage
4. Energy Management System (EMS)
5. Optional bidirectional-ready DC EV charging

The result is a modular solar-plus-storage system that can be configured for residential photovoltaic installations, battery self-consumption, smart energy management and appropriately designed backup applications.

The EV DC charging component is optional; it is not automatically included with every SigenStor configuration.

How Does SigenStor Work?

During daylight hours, electricity generated by connected solar panels can supply the building’s electrical loads.

Available surplus photovoltaic electricity can charge the Sigen battery system.

When solar production decreases, stored electricity can be discharged through the inverter according to the configured operating strategy.

The energy management platform coordinates photovoltaic generation, battery charging, grid interaction and compatible controllable loads.

Depending on the installed equipment, a Sigen Energy Gateway or another manufacturer-approved backup arrangement can provide grid isolation and backup operation.

SigenStor Technical Advantages

Manufacturer-described capabilities include:

• Integrated solar inverter and battery power conversion
• Modular high-voltage LiFePO4 battery storage
• Single-phase and three-phase configurations
• Up to four MPPT trackers on selected controllers
• Battery charging and discharging management
• Integrated battery optimisation
• Advanced battery safety monitoring
• IP66-rated system components
• Smart energy management
• Compatible backup configurations
• Optional DC electric vehicle charging
• Remote monitoring and commissioning
• Supported capacity expansion

Why the Integrated Architecture Matters

In a conventional multibrand solar battery installation, the inverter, battery, BMS, energy meter, communication equipment and backup controller may require separate configuration and compatibility checks.

SigenStor uses a manufacturer-defined system architecture designed to coordinate these functions.

For installers, this can simplify product selection, communication integration and commissioning when all required components are correctly specified.

It does not eliminate the need for electrical design, grid approval, protective devices, battery sizing or verification of the exact system configuration.

Sigen Battery – 5kWh, 6kWh, 8kWh & 10kWh LiFePO4 Storage Modules

Sigenergy offers several Sigen Battery modules for its compatible residential energy storage platforms.

The battery portfolio includes the SigenStor BAT 5.0, BAT 6.0, BAT 8.0 and BAT 10.0 model families.

These model names should not be confused with their actual nominal or usable energy capacities.

Sigen Battery Technical Comparison

The following values come from manufacturer-published specifications. The BAT 6.0 and BAT 10.0 figures appear in manufacturer materials marked preliminary and must be reconfirmed before ordering.

Usable energy is specified under the manufacturer’s defined test conditions. Actual delivered AC energy also depends on operating conditions, battery settings and conversion losses.

Important for installers: The SigenStor BAT 10.0 designation does not mean the battery provides 10kWh of usable energy. The published preliminary specification identifies 9.04kWh nominal and 8.76kWh usable capacity.

For projects requiring a minimum installed energy storage capacity, the correct battery configuration must be verified against the precise tender, subsidy or customer specification.

Sigenergy Battery Safety & Design Features

Depending on the battery model and revision, manufacturer-described features include:

• Lithium iron phosphate battery chemistry
• Integrated battery management
• Cell monitoring and protection
• Battery-level optimisation
• Multi-layer electrical and thermal protection
• Modular expansion
• IP66 enclosure protection
• Natural convection cooling
• Automatic identification of supported battery modules
• Remote operating information through the monitoring system

The manufacturer also publishes cycle-life figures of up to 10,000 cycles under specified cell testing conditions.

These laboratory figures should not be interpreted as a guarantee of 10,000 complete cycles under every operating condition.

SigenStor Battery Expansion – How Many Modules Can Be Connected?

Manufacturer documentation for supported SigenStor configurations describes installations with between one and six battery modules per controller.

For example, using the BAT 8.0 family:

These figures describe battery energy capacity, not the guaranteed AC output power or usable energy of the complete system.

The maximum permitted module quantity depends on the controller, battery generation, firmware, physical installation and manufacturer-approved configuration.

Battery Capacity Is Not the Same as Battery Discharge Power

This distinction is especially important when designing a solar energy storage system with backup functionality.

For example, two BAT 8.0 modules provide approximately 16.12kWh nominal storage capacity.

Their published individual maximum charge/discharge rating is 4kW.

This means battery energy capacity and battery power capability must be considered separately when specifying a complete system.

The inverter’s AC power rating does not automatically establish the maximum power available from the batteries.

Manufacturer technical documents:

• Sigen Battery 5.0 / 8.0 – Official Datasheet (PDF)
• Sigen Battery 6.0 / 10.0 – Preliminary Technical Datasheet (PDF)

Sigenergy SigenStor Neo – Integrated Solar Battery & Backup System

The SigenStor Neo is a newer development within Sigenergy’s residential energy storage portfolio.

It extends the manufacturer’s integrated system approach by incorporating backup functionality directly within the system architecture.

What Is Different About SigenStor Neo?

The manufacturer describes SigenStor Neo as combining:

• Solar PV inverter
• Battery Power Conversion System
• Modular battery storage
• Energy Management System
• Integrated backup module
• Smart control interfaces

This distinguishes it from SigenStor architectures in which separate gateway equipment may be required for the intended backup arrangement.

SigenStor Neo for Residential Installers

Manufacturer-described advantages include a compact design, modular battery expansion, intelligent energy management and simplified integration.

Selected technical features include:

• Up to four MPPT trackers
• Integrated backup connections
• IP66 enclosure protection
• Smart energy control
• Manufacturer-described 0ms load-side disruption under supported conditions
• Integration options for compatible EV charging equipment
• Supported generator connections
• Monitoring through mySigen

The integrated backup design is relevant to installers seeking a more consolidated residential system architecture.

However, SigenStor Neo should not automatically be considered electrically or mechanically interchangeable with the original SigenStor.

Battery compatibility, controller hardware, permitted expansion and country-specific availability must be checked independently.

Current availability of SigenStor Neo through 3Buy Solar is subject to project-specific confirmation.

Sigen Hybrid Inverter – Single-Phase & Three-Phase Battery-Ready Solar Inverters

The Sigenergy Sigen Hybrid Inverter is designed for photovoltaic installations requiring hybrid-ready functionality and future battery storage options.

This platform is particularly relevant to customers who want to install solar panels initially and add energy storage later.

Sigen Hybrid SP2 – Single-Phase Hybrid Inverters

The manufacturer’s SP2 series includes nominal output classes of:

• 2kW
• 3kW
• 3.6kW
• 4kW
• 4.6kW
• 5kW
• 6kW

The series is designed for suitable single-phase residential PV installations.

Manufacturer-described features include a compact enclosure, passive cooling, IP66 protection, smart monitoring and support for compatible battery expansion.

Sigen Hybrid TP2 – Three-Phase Hybrid Inverters

The TP2 family includes nominal three-phase inverter classes of:

• 3kW
• 4kW
• 5kW
• 6kW
• 8kW
• 10kW
• 12kW

These inverters are relevant for three-phase residential systems requiring photovoltaic conversion and storage-ready architecture.

Depending on the model, the manufacturer specifies multiple MPPT trackers, high conversion efficiency and integration with supported Sigen batteries and control equipment.

Why Choose a Battery-Ready Sigen Hybrid Inverter?

For projects where the initial investment is limited to solar generation, a compatible hybrid inverter may provide a route toward later battery integration.

However, the final procurement specification must account for:

• Required battery controller
• Compatible battery modules
• Hardware and firmware revision
• Software activation or licensing requirements, where applicable
• Battery mounting and expansion components
• Metering and communications
• Additional backup equipment

Some manufacturer documentation identifies activation requirements for adding battery functionality to specified hybrid inverter configurations.

Therefore, an inverter described as battery-ready should not automatically be assumed to include every function or licence needed for a later energy storage upgrade.

Professional installers should verify these requirements before quoting the initial installation.

Sigen Energy Controller – Solar PV, Battery & Energy Management

The Sigen Energy Controller forms the central power conversion and control component in supported SigenStor configurations.

The manufacturer provides single-phase and three-phase controller platforms spanning different power classes.

Published product documentation includes:

• Single-phase energy controllers from 3kW to 12kW
• Three-phase energy controllers from 5kW to 30kW

The exact available model range depends on the destination market and current manufacturer portfolio.

Sigen Energy Controller Technical Capabilities

Selected manufacturer-described functions include:

• MPPT solar photovoltaic tracking
• High-voltage battery integration
• Battery charging and discharging
• Three-phase asymmetric output on applicable models
• Energy management functionality
• Remote monitoring
• Supported backup integration
• Advanced electrical protection
• Communication with compatible Sigenergy system components

Selecting the Correct Controller

A larger nominal inverter rating does not automatically mean the installation will benefit from a larger energy controller.

For residential systems, inverter sizing should reflect the photovoltaic array, grid connection, expected electrical demand and battery charging/discharging requirements.

For example, a home with 10kWp of solar panels does not necessarily require a 10kW inverter in every situation.

String orientation, annual yield, export limitations, consumption and battery operating strategy all influence the final design.

Professional buyers should confirm the exact controller designation, electrical specifications and country approval before ordering.

Sigen Energy Gateway – Backup Power & Grid Isolation

The Sigen Energy Gateway is Sigenergy’s backup and energy control platform for compatible residential and commercial systems.

The gateway is designed to manage the transition between normal grid operation and supported backup operation when the public electricity network becomes unavailable.

What Does the Sigen Energy Gateway Do?

Depending on the model and installed equipment, functions can include:

• Grid outage detection
• Grid isolation
• Supported backup switching
• Energy flow monitoring
• Compatible generator integration
• Multiple inverter or storage system coordination
• Smart load management
• Remote monitoring
• Microgrid operating modes

Sigenergy 0ms Backup – What Installers Need to Know

Sigenergy advertises 0ms load-side disruption for selected compatible gateway and system configurations.

This describes a manufacturer-specified operating characteristic of the supported system.

It does not mean every Sigen inverter, gateway and battery combination provides an unconditional 0ms guarantee for every connected appliance.

The actual backup arrangement must be engineered according to:

• Gateway model
• Inverter power rating
• Battery discharge power
• Available stored energy
• Grid connection type
• Neutral and earthing arrangements
• Protection and switching devices
• Essential and non-essential loads
• Motor starting and inrush current
• Local electrical installation regulations

Whole-Home Backup vs Essential-Load Backup

A whole-home backup installation requires sufficient inverter and battery power to supply the intended building loads.

An essential-load system may instead supply selected circuits, such as lighting, refrigeration, communications and critical equipment.

For professional installers, the appropriate configuration should be determined through a load assessment rather than simply selecting the largest battery available.

Sigenergy SigenStack – Modular Commercial & Industrial Battery Energy Storage

The Sigenergy SigenStack is a modular commercial and industrial battery energy storage platform.

Unlike residential SigenStor, SigenStack is designed for larger commercial storage installations using dedicated battery modules and compatible Sigenergy C&I hybrid inverter technology.

SigenStack Technical Specifications

The manufacturer identifies the following characteristics:

SigenStack Battery Capacity Configurations

Based on the manufacturer’s 12.06kWh module specification:

These figures describe the nominal energy capacity of the modules. The complete system’s usable energy and operating power depend on the specified battery controller, inverter and permitted configuration.

SigenStack Commercial Applications

SigenStack is relevant to appropriately designed commercial and industrial projects involving:

• Commercial solar self-consumption
• Peak shaving
• Time-of-use load shifting
• Industrial load management
• Agricultural energy storage
• Warehouse and logistics buildings
• Commercial backup power
• Microgrids
• Supported energy flexibility applications

SigenStack vs SigenStor – Important Compatibility Difference

SigenStack is not simply a larger SigenStor battery tower.

The platforms use different battery architectures, controllers and approved system configurations.

Sigenergy’s SigenStack installation documentation explicitly states that SigenStack cannot be directly integrated with the manufacturer’s SigenStor series devices under the documented architecture.

For professional procurement, the correct C&I inverter, SigenStack battery controller, mounting arrangement and associated balance-of-system equipment must therefore be specified.

Official resources:

• Sigenergy SigenStack – Product Information
• SigenStack Energy Storage Installation Guide (PDF)

Commercial BESS Procurement Through 3Buy Solar

For commercial projects, 3Buy Solar supports enquiries involving appropriately specified commercial and industrial battery energy storage systems.

Provide the required power, energy capacity, installation country, load profile and project schedule when requesting a Sigenergy C&I quotation.

Sigen C&I Hybrid Inverters – Commercial Solar & Battery Integration

The Sigen Commercial & Industrial Inverter range provides power conversion technology for commercial photovoltaic generation and energy storage.

Sigenergy offers dedicated C&I inverter architectures, including configurations intended for hybrid PV and battery storage applications.

• Commercial hybrid inverter operation
• Integration with SigenStack batteries
• Intelligent export control
• Battery charging and discharging
• Remote monitoring
• Advanced electrical protection
• Supported microgrid and backup configurations

Specifying Commercial Sigenergy Systems

For commercial installations, procurement should begin with a clear power and energy specification.

The inverter’s nominal AC output determines its permitted conversion power, while the battery’s nominal and usable capacity determine available stored energy.

The BMS, battery operating range, permitted C-rate and power conversion equipment determine how that energy can be charged and discharged.

For EPC contractors, these parameters must be considered alongside grid requirements, protection coordination, fire safety, installation conditions and operating strategy.

A manufacturer portfolio description alone is not sufficient to approve a complete commercial battery system.

Sigenergy EV Charging – AC Charging, DC Charging & V2X Technology

Sigenergy develops AC and DC charging solutions designed for integration with compatible photovoltaic and battery energy storage systems.

Sigen EV AC Charger – Solar-Compatible Smart Charging

The Sigen EV AC Charger provides smart EV charging functionality for compatible residential installations.

Depending on model and configuration, the manufacturer describes:

• Solar surplus charging
• Scheduled charging
• Dynamic load management
• Monitoring through mySigen
• Integration with SigenStor energy management
• Supported electricity tariff optimisation
• Adjustable charging operation

For solar installers, the charger is relevant to projects where electric vehicle charging should be coordinated with photovoltaic generation, building demand and available electrical connection capacity.

Sigen EV DC Charging Module – 12.5kW & 25kW

The Sigen EV DC Charging Module is designed for integration with supported SigenStor systems.

The manufacturer’s technical specifications identify:

The DC architecture creates opportunities to coordinate solar generation, battery storage and electric vehicle charging within the manufacturer’s integrated system.

Sigenergy V2H & V2G – What Is Actually Supported?

Sigenergy develops bidirectional charging technology for Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) applications.

V2H allows a compatible electric vehicle battery to supply energy to a supported home electrical system.

V2G allows a compatible electric vehicle and charging system to exchange electricity with the grid under an approved operating arrangement.

However, a V2X-ready charger is not proof that every CCS2 vehicle supports bidirectional operation.

Compatibility depends on the exact vehicle model, vehicle manufacturer software, charging equipment, supported standards, system firmware and country-specific operating requirements.

For procurement, the installer must confirm the specific vehicle and charger combination using current manufacturer compatibility information.

Do not promise V2H or V2G capability solely because the charging module is described as bidirectional-ready.

• 1,000W

SigenMicro Technical Features

The manufacturer describes:

• Module-level MPPT optimisation
• Mesh-based wireless communication
• Integrated energy management functionality
• Rapid shutdown capability
• Maximum efficiency up to 97.5%
• IP67 enclosure protection
• Monitoring through mySigen
• Integration options with the wider Sigenergy ecosystem

Microinverters are particularly relevant to smaller PV installations, roofs with challenging module orientations and projects where module-level monitoring is required.

For professional installers, microinverter selection must still consider module voltage and current, AC branch circuit requirements, grid approvals and local electrical regulations.

Browse microinverters and module-level PV equipment at 3Buy Solar.

mySigen App, Sigen Cloud & AI Energy Management

Sigenergy’s energy management ecosystem includes the mySigen App and Sigen Cloud.

These platforms support monitoring, configuration and energy management for compatible Sigenergy installations.

What Can mySigen Monitor?

Depending on the installed hardware and software configuration, available information can include:

• Real-time solar PV production
• Inverter operating status
• Solar battery state of charge
• Battery charging and discharging
• Grid electricity imports and exports
• Building electricity consumption
• EV charging activity
• Historical energy data
• Operating alerts
• Supported remote control functions

Sigenergy AI Mode – Smart Energy Optimisation

Sigenergy also offers AI-assisted energy management designed to use available system data, consumption patterns, weather information and supported electricity tariffs.

Where enabled and properly configured, such functions may help determine when to charge batteries, discharge stored electricity or schedule controllable electrical loads.

The possible financial benefit depends on the applicable electricity tariff, battery operating limits, site consumption and local export arrangements.

Dynamic Electricity Tariffs & Energy Storage

For European installations with dynamic electricity pricing, supported energy management functions can help coordinate grid electricity purchases and battery operation.

For example, a system may be configured to charge batteries when electricity prices are comparatively low and preserve energy for periods when grid electricity becomes more expensive.

The benefit is not automatic.

Installers and energy consultants should verify the electricity contract, available tariff data, applicable taxes and network charges, battery cycling costs and supported control functions.

Sigenergy VPP Readiness

Selected Sigenergy energy management products provide capabilities relevant to Virtual Power Plant integration.

However, VPP participation requires a compatible aggregator or electricity market service, supported communications and the necessary commercial and regulatory arrangements.

VPP capability must therefore be evaluated by country and project rather than treated as an automatically available revenue stream.

Sigenergy Complete Solar Kits – Inverter, Battery, Gateway & PV Components

A complete Sigenergy solar energy storage installation requires more than selecting a controller and a battery stack.

The appropriate equipment list depends on whether the project is grid-connected, backup-ready, EV-integrated or designed for commercial operation.

Typical SigenStor Complete Kit Components

A professionally specified system may require:

• Sigen Energy Controller or compatible hybrid inverter
• Approved Sigen Battery modules
• Battery mounting base and required installation accessories
• Sigen Energy Gateway or other approved backup equipment
• Solar photovoltaic panels
• Smart metering and measurement equipment
• Communication hardware
• AC and DC protective devices
• Isolation and earthing components
• Correctly rated electrical cables
• Photovoltaic mounting structure
• Optional Sigen EV charging equipment

Not every configuration requires every component, and optional modules must not be assumed to be included in the base product.

Example – Three-Phase Solar PV with Battery Storage

A hypothetical residential project may require:

• 10kW-class three-phase Sigenergy energy controller
• Two SigenStor BAT 8.0 modules
• 16.12kWh nominal battery capacity
• A compatible backup gateway where required
• Appropriately matched solar PV array
• Grid metering and protection equipment

This is a sizing illustration, not a preapproved bill of materials.

The final configuration must be checked against the latest manufacturer compatibility documentation and country-specific electrical requirements.
