2.1 Product identification
This equipment 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.
The inverter can be used only with photovoltaic modules that do not require one of the poles
to be grounded.
The operating current during normal operation must not exceed the limits specified in the
technical specifications.
Only the photovoltaic generator can be connected to the input of the inverter (do not
connect batteries or other sources of power supply)
