6. Electrical Connection
PV modules:
GRADE
WARNING
please comply with the electrical safety rules when connecting.
Please ensure they are the same type, have the same output and
specifications, are aligned identically, and are tilted to the same angle.
• PV module voltage is very high and within a dangerous voltage range,
• Please do not make PV positive or negative to ground!
GRADE
In order to save cable and reduce DC loss, we recommend installing the inverter as
close to the PV modules as possible.
GRADE
Please choose a suitable external DC switch if the inverter does not have a built-in DC
switch.
6.1 PV Connection (For Hybrid Only)
Step 1: PV String Connection
AX 1ph series inverters can be connected with 2-strings of PV modules.
Please select suitable PV modules with high reliability and quality. Open circuit
voltage of module array connected should be less than 600V, and operating
voltage should be within the MPPT voltage range.
