X3-Hybrid can be connected with PV modules in series with 2 MPPTS for
5.0KW, 6.0KW, 8.0K W 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.
The configuration current should be under the maximum DC input current.

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
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 hear a “click” sound the pin contact assembly is
seated correctly.
