6.5 PV Connection

Danger of electric shock!
The PV array will generate lethal high voltage once exposed to sunlight. Ensure all cables
•
are voltage-free before performing electrical operations.
Do not connect the AC circuit breaker before finishing electrical connection.
•
Make sure the PV arrays are well insulated to ground before connecting it to the inverter.
•
Make sure the voltage, current and power ratings of the PV arrays are within the
•
permissible range.
Make sure polarity is correct. The inverter will not function properly if any PV polarity is
•
reversed.
The 3.68kW/6kW inverter is designed with 2 MPPT trackers, if the inputs of the PV
•
panels are paralleled, please consult with your local distributor for technical support.
To avoid any malfunction, do not connect any PV Arrays with possible current leakage to
•
the inverter. For example, grounded PV Arrays will cause current leakage to the inverter.
Make sure DC switch on "OFF" position. Otherwise please use an external PV switch to
•
cut off the PV connection during wiring and when necessary.
Use IEC61730 class-A Rating PV Arrays.
•
To ensure IP65 protection, use the right PV plugs in the package.
•
Damage to the device due to the use of incompatible terminals shall not be covered by
•
the warranty.
All wiring must be performed by qualified personnel.

Wiring Connection Procedure：
The AC cable should be prepared by customers. LIVOLTEK provides corresponding PV
connectors in the scope of delivery for quick connection of PV inputs. To ensure IP65 protection,
use only the supplied connector or the connector with the same ingress of protection.

Step1: Assembling the PV Connectors
• Strip the insulation from each PV cable by 6mm –8 mm.
• Assemble the cable ends with the crimping pliers.
• Lead the cable through the cable gland and insert the crimp contact into the insulator
until it snaps into place. Gently pull the cable backward to ensure firm connection.
• Tighten the cable gland and the insulator.
