5.1 PV Connection

X3-Hybrid G4 series inverter have two PV inputs. Please select
photovoltaic modules with good performance and quality assurance.
The open circuit voltage of the module array should be less than the
maximum PV input voltage specified by the inverter, and the working
voltage should be within the MPPT voltage range.

Max. DC input voltage
Warning!
The voltage of photovoltaic modules is very high, and is
dangerous voltage. When wiring, please follow the safe
electricity regulations.
Note!
Please do not make PV positive or negative ground!
Note!
The following PV module requirements need to be applied to
each input range:
1. Same model
2. Same quantity
3. The same queue
4. The same angle
Note!

Connection step
The PV port wiring of X3-Hybrid G4 M series inverter has been
completed. For speci c installation details, please refer to the X3-
Matebox Quick Installation Guide, the D series needs to be wired
according to the following steps.
Step 1. Turn off the DC switch, connect the PV module, prepare a 12AWG
PV cable, and find the PV (+) terminal and PV (-) terminal in the package.

Step 3. Tighten the cable with the insulation layer stripped and insert it into
the metal terminal (see Figure 1), make sure all wires are inserted Into the
metal terminal (see Figure 2).
