iv. Use multi-meter to confirm the total input power of PV strings in order
to ensure the input power from PV string will not be exceed the
permission setting 600V
according to electrical specification of PV inverter and the maximum
DC input current should be within 20A to each pole of DC terminal.
IMPORTANT
Configuration of the PV modules should be done by qualified
service personnel with the instructions that are provided from the
manufacturer of the PV modules.
Ensure the configuration for each string of the PV-system meets the
specifications required by the Eaton grid-tied PV Inverter.
Multi-Meter
It is important to use a multi-meter to measure the DC input voltage
that is generated from the PV modules which must not exceed
600V
DC.
IMPORTANT
The Eaton grid-tied PV Inverter is designed with a transformer less
topography. It is not recommended to connect with the PV modules
that require positive (+) or negative (-) polarity to ground.
And it is also necessary to have a circuited breaker or fuse switch
installed between PV modules and PV Inverter. When there is PV string
connected with the circuited breaker or fuse switch, please ensure to turn
it off in order to prepare connect the DC cables to the DC input terminal of
PV inverter.
B) For the DC cables, the terminal connectors is recommended to be used
with cables in order to ensure the quality of conducting between DC
cables and DC terminal is good as shown in figure 7.1.2.
