Note a: The maximum input voltage is the upper threshold of the DC voltage. If the input voltage exceeds the threshold, the solar inverter may be damaged.

Note b: If the input voltage is beyond the operating voltage range, the solar inverter cannot work properly.

Note c: PV strings connecting to the same MPPT must contain the same quantity and model of PV modules. It is recommended that the PV string voltage be higher than the lower threshold of the full-load MPPT voltage.

Note a: When the SUN2000 is disconnected from the grid and stops working, the built-in PID can achieve the PV– positive offset of the PV module. (PV– positive offset refers to raising the voltage between PV– and the ground to above 0 V through voltage compensation.) When designing a power plant, confirm with the PV module manufacturer that the anti-PID voltage compensation direction of the PV module is the same as the direction of the PV– positive offset. Otherwise, PV modules may be damaged.
