Connecting Multiple Inverters through RS485
Before connecting multiple inverters, make sure your inverters' firmware version
supports this feature. For further information, contact SolarEdge support.
You can add inverters to your system to increase on-grid and backup power
production. Up to two additional Single phase inverters with HD-Wave technology or
Energy Hub inverters may be connected to a single Energy Hub inverter.
If a battery and Backup Interface are installed, the AC output from the additional
inverters must be connected to the Backup Interface. Use a circuit breaker (CB-UPG-xx-
01) purchasable from SolarEdge. For more information, refer to the
Backup Interface
Installation Guide.
When connecting multiple inverters, use the following cable types:
Communication
- 0.25 mm
2
(0.25–1.5 mm
2
), 600V insulated or CAT6
To connect an additional Energy Hub inverter:
1. Connect the Leader inverter to the Backup Interface, as explained in
Backup Interface (Optional) on page 36.
2. In both inverters, pass the communication cable through Communication Gland 2.
3. In the Follower inverter, connect the cable to the
2nd Inv RS485
connector.
