Safe large-scale battery storage operation

Recognise insulation faults at an early stage, reduce risks

Maximum safety for large battery storage systems

Large-scale battery energy storage systems (BESS) are a key component of the energy transition - but as performance increases, so do the requirements for electrical safety. Insulation faults, leakage currents or age-related signs of wear often remain undetected for a long time and lead to downtime, damage or fires in an emergency.

With suitable monitoring solutions for IT and TN systems, you can detect faults at an early stage, protect your investment and fulfil all relevant standards - without interrupting operations.

Renewable energies - utilising the power of nature safely and efficiently

Suitable protection concepts - customised to the mesh shape

Depending on the design of your system - earthed or unearthed - different protection concepts are required: 
 
Unearthed IT systems: 

  • Insulation monitoring in accordance with Commission Electrotechnique Internationale 61557-8 reliably detects first faults - before they become a failure or safety risk. 

Earthed TN/TT systems: 

  • Residual current monitoring (RCM) in accordance with DIN EN 62020 detects even the smallest earth leakage currents at an early stage - without switching off. 

"Safe energy is no coincidence - it starts with the early detection of critical errors. Those who monitor before there is a fire invest in stability, availability and trust."

Your advantages at a glance

  • Early fault detection safeguards against idle states and consequential damage
  • Continuous monitoring in the operating state
  • Targeted fault localisation 
  • Real-time remote monitoring
  • Standardised implementation
  • Longer service life of your storage solution 

Why act now?

An unnoticed error can cause high consequential costs - from system downtimes and the spread of fire to the impairment of grid stability.
 
 Those who monitor with foresight safeguard operations in the long term. 

Safety. Efficient. Fit for the future.
