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 specied. 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 electricity.
• Strictly follow the installation, operation, and conguration 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 https://www.gesolarinverter.com/.
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 meets UL1741
requirements to avoid shock hazards.
6. Keep the battery o󰀨, 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
specications of the inverter.
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.
Specication 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 rmly.
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.
Warning

02
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°C. Do
not install the equipment at a place within children's reach.
4. Unauthorized dismantling or modication 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 o󰀨 the product before working
on it.
Delayed discharge. Wait 5 minutes
after power o󰀨 until the components
are completely discharged.
Read through the guide before
working on this device.
Potential risks exist. Wear proper PPE
before any operations.
High-temperature hazard. Do not
touch the product under operation
to avoid being burnt.
Grounding point. Indicates the position
for connecting the PE cable.
CE marking Do not dispose of the inverter as
household waste.Discard the product
in compliance with local laws and
regulations, or send it back to the
manufacturer.
