Energy storage systems
C&I Energy Storage Systems for Commercial Projects in Europe
SAKETE energy storage systems are organized by system architecture: battery cabinets, Battery Cabinet ESS with External Hybrid Inverter, all-in-one ESS and containerized ESS.
This section explains ESS as a system outcome: battery storage plus a matched hybrid inverter or PCS, with BMS, EMS, protection and cabinet or container architecture.

ESS system composition
A complete ESS is not only a battery cabinet. For C&I projects, SAKETE matches the battery side with a hybrid inverter or PCS, then adds BMS, EMS, protection and cabinet or container integration.
+
Battery + Hybrid Inverter
Used for PV plus storage projects where a hybrid inverter manages solar, battery and grid interaction.
Battery + PCS
Used for larger C&I ESS projects where PCS handles bidirectional power conversion.
=
Complete ESS
Battery, inverter or PCS, BMS, EMS, protection and enclosure become one project-ready system.

Product FAQ
What makes a battery product a complete ESS?
A complete ESS combines battery storage with a matched hybrid inverter or PCS, plus BMS, EMS, protection and cabinet or container integration.
What does external hybrid inverter ESS mean?
It means the battery cabinet is paired with a separate external hybrid inverter instead of being fully integrated inside one cabinet.
Are PCS products included in ESS matching?
Yes. PCS matching is part of the ESS architecture for larger C&I storage projects, especially all-in-one and containerized systems.
Are the systems grid-code compliant?
Yes. PCS options support European grid-connection codes including EN 50549, VDE-AR-N 4105, G99 and IEC 62116 anti-islanding, confirmed per project and country.
