Connect the PV strings
As the PV string generates power as long as illumination exists, a circuit breaker shall be installed between the PV string and inverter so that
the power from PV string can be switched off when needed (e.g. regular maintenance)
Connect the cables from PV string to PV input terminals as shown below. Please check the polarity before connection.
Connect to Utility and charge Connect AC input Cables and loads
Connect the AC input cables and loads to the receptacles as shown below.
Plug in the AC input power cord to the wall outlet. The unit will automatically charge the connected external battery even though the unit is off.
AC input voltage range selector
“NARROW “setting:
Configure LCD 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 input voltage range is set at 170~280VAC while output voltage follows input voltage.
“WIDE “setting:
Configure LCD to “WIDE” when connected with loads which are less sensitive on voltage range (e. g. light bulb, fan, fluorescent tube, or TV). With
this setting, the input voltage range is set at 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.
