NOTICE
Ensure that the selected terminal can directly contact with the copper bar. If there are
any problems, contact the terminal manufacturer.
Ensure that the copper bar is not in direct contact with the aluminum wire. Otherwise,
electrochemical corrosion may occur, impairing the reliability of electrical connection.
5.5 External Protective Grounding Connection
DANGER
Electric shock!
• Make sure that the grounding cable is connected reliably. Otherwise, it may cause
electric shock.
WARNING
• Since the inverter is not equipped with a transformer, neither the negative elec
trode nor the positive electrode of the PV string can be grounded. Otherwise, the
inverter will not operate normally.
• Connect the grounding terminal to the external protective grounding point before
AC cable connection, PV string connection, and communication cable connection.
• The external protective grounding point provides a reliable ground connection. Do
not use an improper grounding conductor for grounding, Otherwise, it may cause
product damage or personal injury.
• Depending on Local Rules, please also ground the PV panel subconstruction to the
same common grounding point (PE Bar) in addition to local lightning protection
rules.
WARNING
It is suggested that the external protective grounding terminal and the AC side ground
ing terminal are both connected to ground. Other grounding schemes, which meet the
local standards and safety regulations, may also be adopted. However, SUNGROW
shall not be held liable for any consequence caused thereby.
5.5.1 External Protective Grounding Requirements
All non-current carrying metal parts and device enclosures in the PV power system should be
grounded, for example, brackets of PV modules and inverter enclosure.
When there is only one inverter in the PV system, connect the external protective grounding
cable to a nearby grounding point.
