01 Safety Precautions
• The information in this quick installation guide is subject to change due to product updates
or other reasons. This guide cannot replace the product labels or the safety precautions in the
user manual unless otherwise specified. All descriptions here are for guidance only.
• Before installations, read through the quick installation guide and the user manual to learn
about the product and the precautions.
• All installations should be performed by trained and knowledgeable technicians who are
familiar with local standards and safety regulations.
• Check the deliverables for correct model, complete contents, and intact appearance. Contact
the manufacturer if any damage is found or any component is missing.
• Use insulating tools and wear personal protective equipment when operating the equipment
to ensure personal safety. Wear anti-static gloves, clothes, and wrist strip when touching
electron devices to protect the inverter from damage. The manufacturer shall not be liable for
any damage caused by static.
• Strictly follow the installation, operation, and configuration instructions in this guide and user
manual. The manufacturer shall not be liable for equipment damage or personal injury if you
do not follow the instructions. For more warranty details, please visit

General Disclaimer
DC Side:
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 the 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.
Ensure the minimum isolation resistance of the PV string to the ground exceeds 19.33kΩ
to avoid shock hazards.
6. Keep the battery off, and the inverter disconnects with PV panels and other AC power
before connecting the battery and the inverter. The rated voltage of the battery should
meet specifications of the inverter.
7. The PV modules used with the inverter must have an IEC61730 class A rating.
AC Side：
1. The voltage and frequency at the connecting point should meet the on-grid requirements.
2. An additional protective device like the circuit breaker is recommended on the AC side.
Specification of the protective device should be at least 1.25 times the AC output rated
current.
3.
PE cable of the inverter must be connected firmly.
4. You are recommended to use copper cables as AC output cables. Contact the manufacturer
if you want to use aluminum cables.
