Product identification
Field of use
The inverter is a multi-string inverter designed to transform a direct electric current (DC)
coming from a photovoltaic generator (PV) into an alternating electric current (AC) Suitable
for being fed into the national grid.
Figure2-1 PV Grid-tied System
The inverter can only be used with photovoltaic modules for on-grid PV power generation. It
cannot be used as other or extra purposes, Device manufacture or supplier does not have
responsibility to any loss caused by other purpose usage. And customer should take
responsibility to risk and loss of other purpose usage. Customer should follow this manual
for PV on-grid power generation usage. The input of inverter can only be PV panel, if user
uses DC source or battery to test the inverter, it may cause device damage , product
damage or human injure, device manufacture/supplier does not have responsibility for
these.

。
For the TT type of electricity grid
，
the voltage between
neutral and earth should be less than 5V.
