Executive summary
Segment RS485/Ethernet gateways, disable unused services and plan firmware signing before connecting storage to the plant network.
What buyers should verify first
A connected ESS is an OT asset. Put gateways in a segmented VLAN, disable unused ports, and avoid default passwords on SNMP community strings.
Engineering and operations notes
Prefer signed firmware updates and a change ticket for every flash. Keep a known-good image offline.
Practical rollout tip
Include battery systems in the plant incident response runbook.
Buyer checklist
Put temperature, load profile and protocol into the RFQ.
Request certificates and traceability for the exact PO model.
Pilot before fleet rollout.
FAQ
Is air-gap mandatory?
Not always, but if you bridge to IT, treat the gateway like any other critical OT device.
