AlphaESS STORION-H30/H50 G3
All-in-one hybrid commercial 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
Manage peak demand
Respond to tariff periods
Support selected loads
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.
AC-coupled

DC-coupled

hybrid-coupled

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.

Monitor and control the system around site priorities
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. Together, these product features and project-specific measures create a layered approach to safety, supporting dependable operation throughout the system lifecycle.

Featured Case Studies

Discover how an AlphaESS SMILE-G3-S8 inverter and 28.8 kWh of battery storage helped a UK household make greater use of solar generation and shift electricity use away from peak periods.

See how Immersa and Natural Generation delivered one of the UK’s first AlphaESS StaX-M50 commercial battery storage systems at Chynoweth Farm in Cornwall.

Sustainable Renewable Energy Solutions installed and commissioned an AlphaESS STORION-G3-H50 at Pendleside Hospice in Burnley, supporting the organisation’s energy management and resilience objectives.

Solar Power Provider installed a dual AlphaESS STORION-G3-H50 system at TH Flower & Sons, creating one of the UK's first parallel H50 commercial battery installations.
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.
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.
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.
The platform supports parallel operation. Parallel configurations are available within approved system limits. AlphaESS UK will confirm the permitted number of cabinets, operating mode and complete system architecture for the selected product revision and project requirements.

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.
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.
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.
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.
