● 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.
Networking Application
The SUN2000 applies to residential rooftop grid-tied systems and small-sized
ground grid-tied PV plants. Typically, a grid-tied system consists of PV strings, grid-
tied inverters, AC switches, and power distribution units.

NO TE
● 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.
