C&I BESS · ZTT ENERGRID M261
ZTT ENERGRID M261 · 261 kWh BESS for business sites
Commercial and industrial storage cabinet with 261 kWh, liquid cooling and an integrated architecture.
KES Energy integrates ENERGRID M261 for self-consumption, demand management, peak shaving and energy flexibility projects. ZTT publishes the model as a 130.5 kW / 261 kWh C&I system; additional technical documentation is available for the 135 kVA reference configuration.

Compact format for distributed storage
The cabinet combines battery, PCS, BMS/EMS and liquid cooling in a format developed for commercial and industrial installations. Final protection and connection architecture is engineered around the actual site.
ENERGRID M261
Typical applications
An integrated C&I platform
261 kWh in one cabinet
A compact way to add storage without immediately moving to a containerised system.
Liquid cooling
Thermal management intended to support stable operating conditions in business applications.
BMS + EMS
Architecture prepared for battery supervision, monitoring and energy strategy.
Project scaling
Capacity can be expanded with multiple cabinets when the electrical architecture supports it.
ENERGRID M261
Protection and thermal management
Available ENERGRID M261 documentation describes LFP batteries, liquid cooling, IP54 protection and integrated management/protection functions. The exact fire detection and suppression configuration must be confirmed for each supply.
EMS and operating strategy
EMS integration can coordinate charge/discharge setpoints, self-consumption, peak shaving and monitoring. Operating logic is configured around tariffs, load curves, PV generation and customer objectives.
Backup depends on project architecture
M261 may be integrated into a backup solution, but transfer mode, island operation, critical loads and additional equipment must be engineered. KES Energy does not assume off-grid capability without confirming the exact PCS, protections and transfer scheme.

General data
Technical sources: official ZTT ENERGRID M261 publications and model-specific technical documentation. Active power (130.5 kW) and apparent power (135 kVA) are shown separately to avoid mixing units.
Documentation and verification
Model-specific technical and transport documents are available for ENERGRID M261. Before supply, KES checks the applicable revision and project-required certificates.
- UN38.3: test documentation available for ENERGRID M261
- MSDS: model-specific system documentation available
- LFP 832 V / 314 Ah / 261 kWh identified in model documentation
These documents are not presented as automatic Spanish grid-connection approval. Regulatory compatibility, protections and DSO requirements must be checked for each project.
EPC integration by KES Energy
KES reviews consumption, PV, power, protections and space before defining the cabinet count and integration architecture.
