● indicates a power cable, indicates a signal cable, and indicates wireless
communication.
● Inverters cannot be cascaded in the SmartGuard networking.
● The voltage of dierent maximum power point tracking (MPPT) circuits must be the
same.
● The MPPT voltage must be greater than the lower threshold of the full-load MPPT
range specied in 9 Technical Specications. Otherwise, the inverter will be derated,
causing the system yield loss.
Supported Power Grid Types
The SUN2000 supports the following power grid types: TN-S, TN-C, TN-C-S, and
TT. In the TT power grid, the N-to-PE voltage must be less than 30 V.
