NO TE
The grid-tied and o-grid ESS supports a maximum of three SUN2000-(2KTL-6KTL)-L1
inverters (with batteries) cascaded. In this scenario, the inverters can be connected to the
grid only at the same phase and controlled only by a single-phase power meter. Grid
connection at dierent phases or using a three-phase power meter is not supported.
NO TE
The parameters of each battery need to be set separately. When the grid charging function
is enabled, the surplus power generated by one inverter can be used to charge the other
inverter.
WARNING
In the o-grid state, the output phases of cascaded inverters are dierent. The
load outputs of the Backup Boxes connected to each inverters cannot be
connected in parallel. As shown in the following gure, the P-1 output is
connected to primary O-1 and the P-2 output is connected to O-2. The P-1 and
P-2 load outputs cannot be connected in parallel.
Smart Dongle Networking
A maximum of three inverters can be cascaded in the grid-tied and o-grid ESS.
The batteries, power meter, Smart Dongle, and Backup Box need to be connected
to the same inverter.
