6. Electrical Connection
X3-Hybrid can be connected with PV modules in series with 2 MPPTS for
5.0KW, 6.0KW, 8.0KW and 10.0K W.
Select PV modules with excellent function and reliable quality. Open-circuit
voltage of module arrays connected in series should be under Max. DC input
voltage; operating voltage should be conformed to MPPT voltage range.

PV module voltage is very high, which already achieve dangerous
voltage range, please comply with electric safety rules when connecting.
Please do not make PV positive or negative ground!
Warning!
Note!
Please choose a fitting external DC switch if the model (X3-Hyrbid-5.0-
N,X3-Hyrbid-6.0-N, X3-Hyrbid-8.0-N, X3-Hyrbid-10.0-N) is purchased.
The following requirements of PV modules need to be applied for each
input area;
- Same type - Same quantity - Identical alignment - Identical tilt
Please do not make PV positive or negative ground!
In order to save cable and reduce the DC loss, we suggest to install the
inverter near PV modules.
Connection Steps:
Step1. Checking PV module.
1.1 Use multimeter to measure module array voltage.
1.2 Check the PV+ and PV- from the PV string combiner box correctly.
1.3 Please make sure the impedance bewteen the positive pole and negative pole of PV to earth
should be MΩ level.
Step2. Separating the DC connector.
Step3. Wiring.
3.1 Choose the 12 AWG wire to connect with the cold-pressed terminal.
3.2 Remove 10mm of insulation from the end of wire.
3.3 Insert the insulation into pin contact and use crimping plier to clamp it.
Step4. Insert pin contact through the cable nut to assemble into back of the
male or female plug. When you feel or heard a “click” sound the pin contact
assembly is seated correctly.
