Sentinal 100 C&I All-in-one BESS 98.2% Efficiency | 50kW | 100kWh The Sentinal 100 is a fully integrated C&I battery energy storage system combining PV-storage-diesel hybrid inverter, LFP battery, BMS, and HVAC cooling in a single cabinet. This all-in-one ESS delivers 50 kW / 100 kWh with 98.2% efficiency and UPS-grade transfer speed — purpose-built for space-constrained commercial and industrial sites.

High Energy Density with Ultra-Compact Footprint

The Sentinal 100 BESS is engineered for maximum spatial efficiency. The entire system — inverter, battery, BMS, and cooling — is contained within a single cabinet with a total installation footprint of ≤2 m².
- Power density: 25 kW/m² — more than 2× higher than conventional C&I energy storage systems
- Cabinet dimensions: 1125 × 1270 × 2080 mm (±10 mm)
- Integrated battery rack with vertical module stacking
- Side-mounted inverter to minimize horizontal footprint
- Dedicated HVAC air-duct integrated within the cabinet structure
Ideal for C&I sites with limited floor space but sufficient ceiling height, including rooftop plant rooms, manufacturing floors, and urban commercial buildings.

98.2% System Efficiency

The Sentinal 100 uses a unified DC bus architecture that directly couples PV generation and battery storage, eliminating the redundant DC-AC-DC conversion cycles found in AC-coupled energy storage systems.
- Max. system efficiency: 98.2%
- European efficiency: 97.1%
- Supports 4 independent MPPT inputs (180–900 V range, up to 36 A per MPPT)
- Max. DC input voltage: 1000 V
- Reduced annual energy loss by up to 37% vs. traditional ESS topologies (usage-scenario dependent)
The DC bus architecture is the same high-efficiency approach used in leading DC-coupled commercial BESS deployments globally.

High-Safety LFP Battery with Precision HVAC Cooling

The Sentinal 100 uses a 96S1P LFP cell configuration (314 Ah @ 307.2 V nominal) that prioritizes safety and long cycle life.
- Cell type: LFP (Lithium Iron Phosphate) 3.2 V / 314 Ah
- Battery configuration: 96S1P (single string — no parallel cell strings)
- Single-string architecture eliminates cell imbalance risk from parallel strings
- Rated energy: 96.6 kWh (at 0.5C charge/discharge rate)
- Operating voltage range: 249.6 – 350.4 V
- Cooling: Precision HVAC with dedicated internal air duct
- Operating temperature: -20°C to 50°C (derating above 45°C)
- Protection rating: IP55
The single-string LFP design is a deliberate safety architecture choice — the same approach referenced in high-safety industrial BESS applications — minimizing the risk of cell imbalance faults.

UPS-Grade Power Continuity

The Sentinal 100 BESS uses an advanced state-machine control algorithm to achieve seamless grid-to-battery switching.
- Grid / off-grid transfer time: <10 ms
- Meets UPS Tier-3 availability standards (99.999% uptime class)
- EPS rated output: 50 kW (75 kW / 10 s peak)
- Prevents downtime for precision equipment, PLC systems, and process-critical loads
- Eliminates voltage sags and micro-interruptions
For facilities that cannot afford even a momentary power disruption, the Sentinal 100 delivers sub-10ms transition — a performance level competitive with industrial UPS solutions, now integrated into a BESS platform.

Flexible Scalability

The Sentinal 100 all-in-one BESS is designed for phased growth and evolving energy needs.
- Off-grid: up to 10 units in parallel (500 kW / 966 kWh combined)
- On-grid: greater system capacity achievable
- New units can be commissioned in under 60 minutes
- Supports single-cabinet deployment through multi-cabinet systems
- Suitable for phased project investment and incremental capacity additions
This scalability model mirrors the expandable architectures found in competitive C&I BESS platforms, while offering faster per-unit commissioning.

Smart Monitoring and Open Communication

- Communication interfaces: RS485, WiFi, BLE
- Local and remote monitoring
- Flexible energy management strategy configuration
- Compatible with third-party EMS platforms
