The Amperix records all energy flows and helps to achieve complete energy transparency. The locally autonomous EMS optimises the control of generation and storage systems as well as larger consumers such as heat pumps or charging infrastructure. Devices from different manufacturers can be integrated into the EMS. Several energy management strategies can be linked in a decision tree to meet more complex requirements, e.g. to use a storage facility at different times for different purposes, or to reserve part of the storage facility for peak load capping or backup power. The myPowerGrid platform offers professional data visualisation and analysis of the EMS data.

Costs
Costs at building level
These are rough estimates. An offer must be requested for exact cost information.
The following use case was assumed for the cost estimate:
1 Multi-party residential building with the following components (excluding commercial):
- Measuring units: 20 electricity meters, 20 heat meters, 20 water meters (hot & cold)
- 1 photovoltaic system (with 1 inverter)
- 1 heat pump (SG-Ready)
- 1 hot water boiler
- 20 parking spaces, 5 of which are fully equipped with charging stations
-
Of these, the following functions can be fulfilled:
Measure electricity meterMeasure heat meterMeasure water meterIntegration PV systemControl heat pumpControl water boilerDynamic load managementImplementation ZEV (pure data delivery - no collection) -
Of these, the following functions cannot be fulfilled:
