Applications
Application scopes served by this product category.
Commercial energy management
Integrated C&I storage supports sites evaluating energy shifting, peak management or backup planning.
Solar + storage deployment
ESS selection can be coordinated with PV generation and hybrid conversion requirements.
Large project storage
Containerized systems support larger installations where site footprint, logistics and protection design become central.
Configuration confirmation
Usable energy, PCS scope, cooling, communication and fire-protection requirements are confirmed for each project.
Selection Criteria
Technical and commercial factors for the applicable product configuration.
Define the operating objective
Peak management, backup, solar shifting and project storage lead to different system sizing priorities.
Confirm power and duration
Required output power and storage duration determine whether an integrated C&I unit or container format is suitable.
Installation and safety scope
Outdoor location, thermal management, fire protection and compliance documents require project-specific confirmation.
Align controls and delivery
PCS, EMS, communication and transport scope should be resolved before final order confirmation.

ESS Selection
ESS formats for commercial and larger projects
Compare cabinet and containerized ESS formats by deployment scale, packaging and project structure.
