- Before connection the PV, please use the multi-meter to measure the PV array voltage to
verify if PV array is working normally, if not, please fix the PV array to normally working
states before connection

The PV connection of LXP hybrid inverter is the same to traditional on-grid solar inverter (string inverter).
Cable Requirement:
Step 1:Turn off or disconnect the PV switch (DC switch). Then keep this switch always open during
the connection.
Step 2:Assemble the PV connector
a) Strip 6~8mm insulation from the cable end.
- When your PV panel ambient temperature could possibly be lower than 0℃, then please
check the PV array voltage up ceiling and if you are not sure please ask your system or
panel provider for further assistance. As when temperature is extremely low the PV panel
voltage will increase by a certain percentage.
b) Assemble the cable ends to crimp contacts.
c) Lead the cable through the cable gland, then insert into the corresponding insulator until it snaps
into place, then tighten the cable gland.
When verified the PV connector is tightly, align the 2 half connector and mate them together by hands
until ‘click’ is felt or heard.
