Communications & Data Analytics; Maintenance And Management - Nuvation Energy S801 Product Manual

Flow-Through I/O
Control all points in the BMS from a single interface.
Communications Status
Reports networking communication status and communication issues from stacks within the pack.
Faults and Warnings
Monitor all system-wide faults and warnings or—for a finer level of control—drill down into detailed
battery pack diagnostics.
3.2.3. Communications & Data Analytics
Isolated BMS Network Traffic
Separate Ethernet ports isolate BMS network traffic from external network traffic, helping ensure
your energy storage system is hardened and reliable.
Inverter Support
Modbus TCP supports MESA Draft 3 storage models for connection to power conversion systems as
well as other external systems through multiple concurrent client connections.

3.2.4. Maintenance and Management

Multi-Stack Current Limiting
Determine operating current limits for entire pack, which can be read by the external system to
control the inverter, protecting the battery pack from over-charging or discharging.
Pack-Level Fault Response
A highly configurable architecture allows a Nuvation Energy support technician to specify system
faults and desired responses. The Multi-Stack Controller flags faults anywhere in the battery pack
and automatically takes preventive action to keep the battery functional and healthy.
Servicing
Bring stacks online/offline for service, maintenance, modifications, etc. Selectively connect
multiple stacks to the DC power bus.
Network Environment Flexibility
A multi-socket Ethernet interface allows concurrent operation of both local and remote operator
panels, monitoring data and interfacing with inverters over Modbus TCP. SFP+ interfaces allow
long-distance fibre connectivity without external hardware.
Provides Remote Support
The Multi-Stack Controller provides the option of a secure VPN connection to a Nuvation Energy
server which grants Nuvation Energy support engineers remote access to check on the health of
the battery pack and aid the local site commissioning team.
