● If the built-in Wi-Fi module of the SUN2000 connects to the app, only device commissioning
can be performed.
● If inverters are cascaded without any battery, the main inverter model can be
SUN2000-(3KTL-10KTL)-M1 Series. The slave inverter model can be SUN2000-(3KTL-10KTL)-
M1 Series, SUN2000-(8KTL-20KTL)-M2, SUN2000-(20KTL-40KTL)-M3,
SUN2000-(5KTL-20KTL)-M0, SUN2000-50KTL/60KTL/65KTL-M0, SUN2000-29.9KTL/36KTL, or
SUN2000-33KTL-A.
● If inverters are cascaded with an ESS, M1/M2/M5/MB0 can be cascaded. Each 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.
● For details about the EMMA networking scenario, see the Residential Smart PV Solution
Quick Guide (Three-Phase PV+ESS Scenario + EMMA Networking).
For detailed operations on devices in the network, see the following guides:

Backup Box-(B0, B1) Quick Guide
The o-grid load output port of the Backup Box cannot be directly connected to
the power grid. Otherwise, the Backup Box will be shut down due to overload.
● For a PV string connected to an MPPT circuit, the model, quantity, orientation, and tilt
angle of PV modules in the PV string must be the same.
● The voltage of dierent MPPT circuits must be the same.
● The MPPT voltage must be greater than the lower threshold of the full-load MPPT
range specied in the inverter technical data sheet. Otherwise, the inverter will be
derated, causing the system yield loss.
Supported Power Grid Types
The SUN2000 supports TN-S, TN-C, TN-C-S, TT, and IT power grids.
