Before connecting solar modules, make sure that the voltage specified by the man-
ufacturer corresponds to the actual measured voltage.
Note the safety instructions and specifications of the solar module manufacturer regarding
solar module grounding.

DC terminals

Functional grounding isnot permitted
The inverter must not be used as part of a three-phase combination, as there is no
communication link between the inverters
The open circuit voltage of the solar modules increases as the temperature decreases
(assuming constant irradiance). Open circuit voltage may not exceed the following val-
ues:
Fronius Galvo 1.5-1 ... 420 V
Fronius Galvo 2.0-1 ... 420 V
Fronius Galvo 2.5-1 ... 550 V
Fronius Galvo 3.0-1 ... 550 V
Fronius Galvo 3.1-1 ... 550 V
If the open circuit voltage exceeds the above mentioned values, the inverter may be
damaged, and all warranty rights will become null and void.
Note the temperature coefficients in the solar module data sheet
More exact data for sizing the solar array for the particular location can be obtained
using calculations tools such as the Fronius Solar.configurator (available at http://
www.fronius.com).

Cable cross sections of each DC cable:
minimum 2.5 mm² - maximum 16 mm²
The DC cables can be connected to the DC
terminals without ferrules.
Note! To ensure effective strain relief of the

solar module strings, only use cables with
identical cross-sections.
