Connect the cables from PV string to PV input terminals as shown below. a circuit
breaker with 80A rating shall be installed as shown below, Please check the polarity
before connection.
2.5 Connect AC Input Cables and Loads
Connect the AC input cables and loads to the receptacles as shown below.
2.6 AC Input Voltage Range Selector
A.
“NARROW” setting:
Set the selector to “NARROW” when connected with loads which are more
sensitive on voltage range. With this setting, the inverter is more sensitive to the
voltage disturbance on the AC input and the input voltage range is set at
170~280VAC while output voltage follows input voltage.
B.
“WIDE” setting:
Set the selector to “WIDE” when connected with loads which are less sensitive on
voltage range (e.g. light bulb, fan, fluorescent tube). With this setting, the inverter’s
input voltage range is extended to 90~280VAC while output voltage follows input
voltage.
Please note that the inverter’s transfer time switching from Line
Mode to Backup Mode gets longer as the input voltage gets low.
Under the circumstance, connecting the inverter with loads which
are sensitive to transfer time (e.g. computer) might result in power
interruption.
