● When the grid charging function is enabled, the surplus power generated by the inverter
without batteries can be used to charge the inverter connected to the batteries.
● 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.
● The grid-tied 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.
● Each L1/LC0/M1 can connect to a maximum of two ESSs, and each MB0 can connect to
a maximum of four ESSs. In the Smart Dongle networking scenario, a maximum of
three inverters and six ESSs can be connected.

The grid-tied ESS supports inverter cascading. A maximum of three inverters can
be cascaded.
