General Disclaimer
• 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. For additional information, please see the user
manual.
• 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 electronic components to
protect the inverter from damage. The manufacturer
shall not be liable for any damage caused by static

WARNING
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
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. 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. Additional protective devices like circuit breakers or
fuses are recommended on the AC side.
Specification of the protective device should be at least
1.25 times the rated 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. If you prefer aluminum cables, remember
to use copper to aluminum adapter terminals.
Product Enclosure:
1. Do not apply mechanical load to the terminals,
otherwise the terminals can be damaged.
2. All labels and warning marks should be visible after the
installation. Do not scrawl, damage, or cover any label
on the device.
3. Do not touch the running equipment to avoid being
hurt as its temperature may exceed 60℃. Do not install
the equipment at a place within children's reach.
4. Unauthorized dismantling or modification may damage
the equipment, the damage is not covered under the
warranty.
5. Do not start the BACK-UP function if the inverter is
not connected to the battery.
6. Warning labels on the inverter are as follows.
HIGH VOLTAGE HAZARD.
Disconnect all incoming power and turn
off the product before working on it.
Delayed discharge. Wait 5 minutes
after power off until the components
are completely discharged.
Read through the guide before working
on this device.
