AlphaESS STORION H30/H50 G3
All-in-one hybrid storage

STORION H30/H50 G3 combines battery storage, power conversion, solar input, switching and energy management within a compact outdoor cabinet.

Choose between 30 kW and 50 kW nominal output, then configure battery capacity around the site’s load profile, solar generation, grid connection and commercial energy strategy.

One cabinet, several energy strategies

Increase solar self-use

Store surplus solar generation and use it when the site's demand is higher.

Manage peak demand

Charge and discharge around defined demand periods and site limits.

Respond to tariff periods

Schedule operation around compatible time-of-use or dynamic energy arrangements.

Support selected loads

Design backup around the loads that matter, available energy and approved switching arrangement.
COUPLING OPTIONS

Flexible solar and retrofit options

The platform can support AC-coupled, DC-coupled and hybrid-coupled architectures, creating options for new solar installations, selected retrofit projects and sites where generation and storage use different connection routes.

AlphaESS UK or an authorised commercial project partner must confirm the equipment, metering, export controls, inverter compatibility, protection and grid requirements before the system architecture is approved.

INTEGRATED DESIGN

Compact and pre-installed

The main cabinet brings together battery storage, PCS, DC/DC, STS and EMS within an approximately 1.5 square metre footprint. Factory integration reduces the amount of battery assembly required on site and helps coordinate the principal system components within one enclosure.

Installation still requires an appropriate foundation, lifting plan, electrical protection, equipment clearances, communications, grid compliance and professional commissioning.

All-in-one cabinet
Core power, storage and control components are brought together within one enclosure.
Outdoor design
IP55 protection supports outdoor siting, subject to the complete site assessment.
Pre-installed components
Factory assembly can reduce installation steps and interface risk on site. 
CONTROL & INTEGRATIONS

Monitor and control the system around site priorities

Connected energy management supports self-consumption, peak management, scheduled operation and approved integration with external platforms. The exact functions available depend on the UK product configuration, metering and selected partner service.

Layered safety from battery site

STORION H30/H50 G3 uses lithium iron phosphate battery chemistry together with battery and system monitoring, HVAC thermal management, aerosol fire response and smoke and temperature detection.

Safe deployment also depends on the complete site design, including foundations, electrical protection, access, separation, environmental conditions, emergency planning, commissioning and maintenance. This presents the product features confidently without suggesting that cabinet features alone make every installation safe.

    FAQs
    What is the difference between the H30 and H50?

    The STORION H30 G3 provides 30 kW nominal output with 72.3 kWh standard battery capacity, expandable to 144.6 kWh using the approved extension arrangement. The STORION H50 G3 provides 50 kW nominal output with 120.5 kWh standard capacity, expandable to 241 kWh. The correct model depends on the site’s load profile, generation, grid connection and operating strategy.

    Can the H30/H50 work with an existing solar system?

    Potentially. STORION H30/H50 G3 can support AC-coupled, DC-coupled and hybrid-coupled architectures. Existing inverters, metering, export controls, protection and grid connection arrangements must be reviewed before a retrofit design is confirmed.

    Can it operate during a power cut?

    Compatible configurations can support selected loads during a grid interruption. Backup requires an approved electrical design and switching arrangement. Available power and duration depend on the selected model, connected loads, stored energy, protection settings and commissioning.

    Can several cabinets work together?

    The platform supports parallel operation. Current AlphaESS sources disagree on the maximum number of systems, so the exact UK limit must be confirmed for the selected operating mode and product revision. Learn more in our Dual H50 case study.

    How much space does the cabinet need?

    The main cabinet measures approximately 1,120 mm wide by 1,300 mm deep, giving a footprint of approximately 1.5 square metres. Additional space is required for equipment clearances, foundations, access, electrical equipment and maintenance. Expanded capacity also requires an extension battery cabinet.

    Can it participate in energy flexibility services?

    Supported communications can enable compatible optimisation, flexibility or virtual power plant services. Eligibility depends on the service provider, metering, grid connection, commercial agreement and approved system integration.

    Is the H30/H50 suitable for outdoor installation?

    The main STORION H30/H50 G3 cabinet is rated IP55, supporting installation in a suitable outdoor location. The site assessment must still consider temperature, drainage, access, clearances, foundations, noise, environmental exposure and maintenance requirements.

    What warranty is available?

    A five-year product warranty and a ten-year battery warranty. Coverage, performance conditions, registration requirements and exclusions are governed by the current AlphaESS UK warranty documentation provided for the installed system.
