Safety Disclaimer
Warning
PV panel safety:
1. Ensure the component frames and the bracket system are securely grounded.
2. Connect the DC cables using the delivered PV connectors. The manufacturer shall not be
liable for equipment damage if other connectors are used.
3. Ensure the DC cables are connected tightly, securely, and correctly. Inappropriate wiring may
cause poor contacts or high impedances, and damage the inverter.
4. Measure the DC cable using the multimeter to avoid reverse polarity connection. Also, the
voltage should be under the max DC input voltage. The manufacturer shall not be liable for
the damage caused by reverse connection and extremely high voltage.
5. The PV strings cannot be grounded. Ensure the minimum insulation resistance of the
PV string to the ground meets the minimum insulation resistance requirements before
connecting the PV string to the inverter. R=Max. Input Voltage/30mA.
6. The PV modules used with the inverter must have an IEC61730 class A rating.
Inverter safety:
1. The voltage and frequency at the connecting point should meet the on-grid requirements.
2. Additional protective devices like circuit breakers or fuses are recommended on the AC side.
