Connecting Solar Module Strings to the Fronius IG
Plus (DC)
General Informa-
tion about Solar
Modules In order to select suitable solar modules and get the most efficient use out of the inverter,
please note the following points:
- If irradiance is constant and the temperature is falling, the open circuit voltage of the
solar modules will increase. Open circuit voltage may not exceed 600 V.
Whenever the open circuit voltage of the solar modules exceeds 600 volts, the inverter
may be damaged, and all warranty rights will become null and void.
- More exact values for dimensioning solar modules for the chosen installation location
can be provided using suitable calculation programs like the Fronius Solar.configura-
tor (available at http.//www.fronius.com).
Safety
NOTE! Before connecting solar modules:
- make sure that the voltage specified by the manufacturer corresponds to the
actual measured voltage
- determine whether or not a solar module ground is required
WARNING! An electric shock can be fatal. Danger due to grid voltage and DC
voltage from solar modules.
- The connection area should only be opened by a licensed electrician.
- The separate power stage set area should only be disconnected from the
connection area after first being disconnected from the grid power.
- The separate power stage set area should only be opened by Fronius-trained
service personnel.
Never work with live wires! Prior to all connection work, make sure that the AC
and DC wires are not charged.
The DC main switch is only used to switch off power to the power stage set. When
the DC main switch is turned off, the connection area is still energized.
CAUTION! Danger of damaging the inverter from improperly connected termi-
nals. Improperly connected terminals can cause thermal damage to the inverter
and may cause a fire. When connecting the AC and DC cables, make sure that
all terminals are tightened securely using the proper torque.
