● For two PV strings connected in parallel to the same MPPT circuit, the model, quantity,
orientation, and tilt angle of PV modules in the PV strings must be the same.
● The voltage of dierent MPPT circuits must be the same.
● The MPPT voltage must be greater than the lower threshold of the full-load MPPT
range
specied in the inverter technical data sheet. Otherwise, the inverter will be
derated, causing the system yield loss.
Power Grid Types
Power grid types supported by the SUN2000 include TN-S, TN-C, TN-C-S, TT, and
IT.
