What is a string disconnector?

> A string disconnector is an electromechanical switching element in battery energy storage systems (BESS), used for the disconnection or connection of entire battery modules within a string. In accordance with IEC 60947, it ensures galvanic isolation and the safety of the plant during fault conditions. It is a critical component for insulation monitoring and system segmentation.

No own register — honestly

For this component, no own register is connected; therefore, no example value is intentionally provided here. Where the system measures, the value is read as read-only and calculated internally. It is visible via connected components.

What the AI reads in this component

What the AI reads
  • Galvanic isolation status for insulation fault identification
  • Short-circuit detection within individual battery modules
  • Switching state verification for correct BESS topology
  • Indicator for the use of safety trips in case of overheating or overvoltage
Scenario

Monitored: continuous

The scenario: > Monitored: continuously · every cell, every rack The scenario: a weak cell silently limits capacity, less yield per cycle, no alarm. The AI: tracks outliers over cycles and reports them before they slow down the string. It identifies the trend before the limit value is triggered.

Why it is important

Precise monitoring of the string disconnector minimises downtime through targeted fault location and prevents cascading effects in the BESS. By identifying faults in the string, capacity availability is maximised. This ensures continuous feed-in and optimises the profitability of the battery storage. usable capacity (kWh) · SoC (%) · Reserve (%) → — kWh available Calculation: Capacity × (SoC − Reserve) ÷ 100
