• Ripple Control. The Ripple Control device only needs to be connected to the master in-
verter, which will perform unified scheduling. Refer to "6.12 DI Connection" for the cable
connection. Refer to "8.12.6 Active Power Regulation" to enable it in the iSolarCloud App.
• Parallel Configuration. Refer to "8.12.14 Parallel Configuration" to configure the master
and slave inverters in the iSolarCloud App.
2.7.2 Off-grid Parallel System
• This section is not applicable for Europe but only for other regions. Please con-
tact SUNGROW for details of specific regions and models.
In off-grid parallel mode, devices are controlled by the smart switch at the grid-connected
point, and relevant parameters can be set on iSolarCloud App.

• Batteries in parallel are temporarily not to be connected to inverters.
• Each inverter in the parallel system must be connected with batteries.
• In off-grid parallel mode, SOC equalization of batteries connected to each in-
verter is not supported.
• The sum of the total power of inverters and the load power shall not exceed
the nominal power of the genset.
