Additional Reference; Installation Workflow - SolarEdge StorEdge Solution with Backup Installation Manual

NOTE
Additional SolarEdge inverters (without batteries) can be connected with
RS485. The inverters will participate in export limitation and Smart Energy
Management.
Connecting multiple inverters with RS485 master-slave connection may
require an RS485 Expansion Kit (available from SolarEdge).
PV modules connected to power optimizers are not mandatory for charge/
discharge profile programming and for backup power.
