1. PV connection
BD Hybrid can be connected in series with 2-strings PV modules for
3KW,3.6KW 4KW,4.6KW,5KW and 6KW.
Select PV modules with excellent function and reliable quality. Open-
circuit voltage of module arrays connected in series should be <Max. DC
input voltage; operating voltage should be conformed to MPPT voltage
range.

Warning!
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!
Note!
The following requirements of PV modules need to be applied for
each input area;
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.
Note!
PV connection mode below is NOT allowed!

Connection Steps:
Step1. Checking PV module.
1. Use multimeter to measure module array voltage.
2. Check the PV+ and PV- from the PV string combiner box correctly.
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.
1. Choose the 12 AWG wire to connect with the cold-pressed terminal.
2. Remove 10mm of insulation from the end of wire.
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.
Step5. Plug the PV conntector into the corresponding PV connector on
inverter.
