Discharging power
Discharging power in the SpeicherCampus context: determines how strongly the storage system can intervene during load peaks. Technically, the term is usually described as power during discharge.
What does discharging power mean?
Discharging power is the maximum power in kW the storage system can deliver. It decides how deeply the system cuts into load peaks, how many loads it carries in a backup event, and whether it can buffer charging points effectively.
Beyond the continuous rating, overload capability matters: many systems deliver more for short periods (e.g. 110 % for a few minutes) — relevant for the inrush currents of motors and compressors.
What matters in practice
- check discharging power against the highest simultaneous load to be covered
- inrush currents: use the PCS’s short-term overload capability
- in a backup event, only the power the PCS delivers in grid-forming mode counts
- parallel connection of several systems raises both power and redundancy
Practical example
A cold store needs 60 kW continuous in a backup event, but 95 kW when all units restart. The system with 105 kW of discharging power carries the restart; a 60 kW system would have collapsed despite “sufficient” continuous power.
The SpeicherCampus perspective
SpeicherCampus always calculates discharging power against the loads’ real simultaneity and inrush behaviour — datasheet values are where the check starts, not where it ends.
