6.3 PV Connection
Before connecting, please make sure:

The voltage, current and power ratings of the panels to be connected are within the allowable range of
the inverter, ensure polarity is correct, and please refer to the Technical Data in chapter 9 for voltage
and current limits.

Since the inverter is transformerless, please do not ground either output of the PV panels. Ground the
panel frames.

The HY3 Series inverters are designed with 2 MPPT trackers and the HY3-8000HV/10000HV have 3 PV
inputs. Only one solar string is permitted for one input port. If the inputs of the PV panels are paralleled;
please consult with your local distributor for technical support.

If the inverter is equipped with a PV switch, please make sure it is in the “off” position. Otherwise please
use an external PV switch to cut off the PV connection during wiring and when necessary.
When exposed to light, PV panels will generate DC voltage. One should turn off the PV switch
before connecting the wire, and be careful with the conductors.
Use the PV Connectors in the accessory box for PV connections.
Please make sure the connectors are correct, not the battery connectors, as they look similar.
Procedure
Step 1

Assemble the PV connectors from the
accessary box.

Make sure the polarity is correct.

The conduct core section: 2.5-4mm 2 .
Step 2

Connect the PV connectors to the
inverter.
There should be a “click”
sound, if it is plugged in correctly.
