Operational Brief

Built for energy storage station safety and infrastructure reliability.

Battery energy storage stations depend on more than battery cells. Step-up transformers, PCS rooms, switchgear, cable routes, cooling equipment and auxiliary infrastructure all affect safe and stable operation. HERTZINNO provides a multi-sensor monitoring layer for these critical station assets.

Reliability Risks

Where energy storage station risks usually start

Energy storage safety is not only about battery cells. Many early risk signals appear in transformers, PCS rooms, switchgear, cable corridors, cooling loops and unattended station infrastructure before a visible alarm is triggered.

01

Transformer Fault Risk

Step-up transformers may develop overheating, arcing, insulation stress or moisture-related problems that can be detected earlier through online DGA trends.

02

Electrical Room Risk

PCS cabinets, switchgear, busbars and electrical cabinets may show partial discharge, hot spots or abnormal acoustic emissions before failure becomes visible.

03

Cable Thermal Risk

High-current cable routes, trays and trenches can develop localized heat accumulation, insulation stress or temperature rise in hidden areas.

04

Cooling Equipment Wear

Pumps, fans, compressors, valves and liquid cooling equipment often produce abnormal sound patterns when wear, cavitation, imbalance or flow changes begin.

Sensing Architecture

A multi-sensor layer for BESS infrastructure monitoring.

HERTZINNO does not replace the battery management system. Instead, it adds an external sensing layer for station-level infrastructure: transformers, electrical rooms, cable routes, cooling systems and perimeter or auxiliary areas. The solution combines online DGA, acoustic imaging, distributed fiber optic sensing and AI voiceprint analysis.

Is this solution a battery management system?

No. HERTZINNO does not replace the BMS. The solution provides an additional sensing and monitoring layer for transformers, electrical rooms, cable routes, cooling systems and auxiliary infrastructure around the energy storage station.

Can it monitor battery cell temperature?

The solution is not designed for cell-level temperature monitoring. DTS can be used for route-level or cable-level distributed temperature monitoring, such as cable trays, trenches, liquid cooling routes and selected infrastructure paths.

Why is online DGA useful in energy storage stations?

Energy storage stations often use step-up transformers and auxiliary transformers. Online DGA helps monitor dissolved gas and moisture trends, supporting early warning of overheating, arcing or insulation-related transformer risks.

Can acoustic cameras be used in PCS or switchgear rooms?

Yes. Acoustic and thermal imaging can help locate partial discharge, abnormal acoustic emissions and hot spots in PCS rooms, switchgear rooms and electrical cabinets.

Can the solution connect to SCADA, EMS or BMS?

Yes. HERTZINNO devices can provide alarms, trend data and diagnostic results to SCADA, EMS, BMS, fire safety systems or third-party platforms depending on the project design.

Which products are recommended for a typical energy storage station?

A typical configuration may include DGA900 for transformer monitoring, HZ-FA-371T or HA3T for electrical room inspection, HZ-DTS for cable temperature monitoring, DAS for route-level vibration monitoring and HZ-FA-8 or HZ-FA-110 for cooling equipment acoustic monitoring.
