mounting kits. Hang the inverter to the two recesses
Original Version of the backplate.To protect the inverter from theft,
you can lock it to the backplate with a padlock.
• The theft protection is optional.
• You shall lock the inverter to the mounted eye plate of
the backplate with a suitable (stainless, secured shackle
and lock cylinder) padlock.
• You must ensure that the key is available at all times for
possible service purposes.
3. Allow sufficient room around the inverter to
enable unobstructed air flow during installation.
For multiple inverters installation, positionthe
inverters in staggered arrangement.

6. Check the cable polarities of PV input before PV input connection. Connect the DC plug-in connectors
to corresponding DC terminals. Connect other PV strings following the same procedures if necessary.
Unused DC terminals should be sealed.
The inverter can work on independent mode and parallel mode, you can connect PV input as shown
(In parallel mode, one pair of DC terminals in DC1 input and DC2 input must be short-circuited by
Y-type cable connector terminal.).
The PV input configuration mode should be consistent with the setting in the LCD.
