Functions in Detail:
-
Up to 5 manufacturer-independent battery storage systems, including hybrid systems — up to 25 via master/slave
-
Unique multi-use battery controller with various control strategies:
-
Self-consumption optimisation
-
Peak shaving
-
Seasonal and weekend-dependent operating mode changes
-
SOC allocation, SOC sharing, for mixed operating modes
-
Backup reserve for emergency power, depending on the storage system
-
Extensive interfaces for connection to the grid operator and external components
-
Load shedding relay and alerts for peak shaving applications

Measurement via an external energy meter: S1ProMeter, S1BasicMeter, Janitza UMG
-
PV monitoring and control up to 1,000 kW included
-
Direct integration via inverter, LAN and RS485, for all common inverter manufacturers, or indirect integration via external network energy meter
-
Inverter control via ripple control receiver, dynamic reductions and zero feed-in
-
Support for up to 30 AC/DC charging points — 4 charging points included — expandable to 30 by licence
-
Real-time load distribution for 4 to 30 charging points — dynamically distributes the available power across all AC and DC/HPC stations and prevents grid overload
-
Two freely selectable control points, grid connection point and supply line — each can be configured with dynamic, static or hard limits
-
Fail-safe fallback to a fixed total limit — ensures operation in the event of measurement or communication errors
-
Integrated protection mechanisms — threshold alarms and optional local load shedding via external energy meter
-
Licence: [EZ2-ADD-EMOB-1] EASY2 - AddOn - E-Mobility, licence per charging point
