A NOTICE
WARNING
NOTE PV
modules:
Please ensure that they are of the same type, have the same performance and
specifications, are oriented identically and are tilted at the same angle. To save cables
and reduce DC losses, we recommend installing the inverter as close to the PV
modules as possible.
Please choose a suitable external DC switch if the inverter does not have a built-in
DC switch.
• The voltage of the PV modules is very high and is in a dangerous voltage range.
Please observe the electrical safety rules when connecting.
• Please do not connect PV positive or negative to ground!
6.1 PV connection (only for hybrid)
Step 1: PV string connection
The AX 1ph series inverters can be connected to 2 strings of PV
modules. Please choose suitable PV modules with high reliability
and quality. The open circuit voltage of the connected module array
should be less than 600V, and the operating voltage should be
within the MPPT voltage range.
