Sentinal 100


Ultra-Compact Footprint · 98.2% Efficiency · UPS-Grade Reliability
The ZTTEK Sentinal 100 C&I All-in-One ESS is a fully integrated Commercial & Industrial energy storage system designed for facilities requiring high reliability, small footprint, and superior energy efficiency.
Combining PV-storage-diesel hybrid inverter, battery, BMS, air cooling, and safety functions in a single cabinet, the system provides seamless support for factories, commercial buildings, data centers, telecom, and micro-grid deployments.
50% Smaller Footprint — Best-in-Class Spatial Efficiency (≤2 m²)
With an overall footprint of ≤ 2 m², the Sentinal 100 delivers the industry-leading power density of 25 kW/m², more than 2× higher than conventional C&I solutions.
Key structural features:
  • Integrated battery rack and HVAC air-duct design
  • Side-mounted inverter configuration
  • Vertically stacked battery modules
Ideal for C&I sites with limited floor space but sufficient height clearance.
98.2% System Efficiency — Industry Leading
The system adopts a unified DC bus architecture that directly couples PV and battery power, eliminating multiple DC-AC-DC conversion cycles present in traditional systems.
Benefits:
  • Max. efficiency: 98.2%
  • European efficiency: 97.1%
  • Annual energy loss reduced by up to 37%, depending on usage scenarios
This significantly improves energy yield for self-consumption, peak-shaving, and DC-coupled PV applications.
UPS-Grade Power Continuity: <10ms Transfer Time
The advanced state-machine-based control algorithm enables seamless switching between grid and battery within <10 ms.
Advantages:
  • Prevents downtime of precision manufacturing equipment
  • Eliminates the risk of voltage sags
  • Meets UPS Tier-3 availability standards (99.999%)
With a short-time overload capacity of 75 kVA for 10 seconds, the system also supports motor-starting and surge-load scenarios.
Flexible Scalability: Multi-Units in Parallel
Designed for evolving energy needs, the system supports:
  • Off-grid: Up to 10 units
  • On-grid: greater capacity achievable
  • New units can be added and commissioned in less than 60 minutes
This makes the Sentinal 100 ideal for growing businesses and multi-phase deployment projects.
