● 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 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 Grids
Power grid types supported by the SUN2000 include TN-S, TN-C, TN-C-S, TT, and
IT.

● In a TT power grid, the N-PE voltage should be lower than 30 V.
● In an IT power grid, you need to set isolation settings to input not grounded, with a
transformer.
