EMS
EMS in the SpeicherCampus context: the control center for charging and discharging strategies. Technically, the term is usually described as Energy Management System.
What does EMS mean?
The Energy Management System is the storage system’s control center. At every moment it decides whether to charge, discharge, limit or reserve — based on PV generation, load measurement, tariffs and the configured operating strategy.
Without an EMS, a storage system is just a big battery. The operating logic is what turns it into a system for self-consumption optimization, peak shaving, backup reserve or charging support — and defines which of these tasks wins when they collide.
What matters in practice
- check the available operating modes and how they combine
- prioritization: what applies when peak shaving competes with the backup reserve?
- metering concept: the EMS needs the right measuring points at the grid connection
- openness to external signals (charging management, dynamic tariffs)
Practical example
A business uses its storage for PV self-consumption and wants to hold a 30 % backup reserve in the evening. A simple EMS discharges to its lower limit; a good EMS manages both goals — full self-consumption during the day, a protected reserve from 5 p.m.
The SpeicherCampus perspective
In the OmniCube A215, the integrated EMS controls PV, storage, grid and loads with defined operating modes. The strategy is derived from the load profile during the project review — not improvised afterwards.
