Safety Precaution
The inverters are designed and tested strictly complies with related safety rules. Read and follow all
the safety instructions and cautions before any operations. Improper operation might cause personal
injury or property damage as the inverters are electrical equipment.
2.1 General Safety
•
The information in this user manual 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 operations should be performed by trained and knowledgeable technicians who are familiar
with local standards and safety regulations.
•
Use insulating tools and wear personal protective equipment when operating the equipment to
ensure personal safety. Wear anti-static gloves, cloths, and wrist strips when touching electron
devices to protect the inverter from damage.
•
Strictly follow the installation, operation, and configuration instructions in this 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/warranty.

2.2 DC Side
•
Connect the DC cables using the delivered PV connectors. The manufacturer shall not be liable
for the equipment damage if other connectors or terminals are used.
•
For the GE series the minimum insulation resistance to the ground of the PV panels must
exceed 20kΩ(R=600/30mA). There is risk of electric shock if this minimum resistance
requirement is not met.
•
Ensure the component frames and the bracket system are securely grounded.
•
Ensure the DC cables are connected tightly, securely and correctly.
•
Measure the DC cable using the multimeter to avoid reverse polarity connection. Also, the
voltage should be under the permissible range.
2.3 AC Side
•
The voltage and frequency at the connection point meet the inverter grid connection
requirements
•
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.
•
PE cable of the inverter must be connected firmly. The resistance between the neutral wire and
the earth cable is less than 10Ω.
•
Disconnect the breaker or fuse between the inverter and the utility.
•
You are recommended to use copper cables as AC output cables. Contact the manufacturer if
you want to use other cables.
