provides output resonance self-protection. Its energy yield may decrease if
protection against resonance is triggered as the length of the inverter output
cables decreases.
Take waterproof and insulation measures for unused DC power cables. High
voltage may exist in unused DC power cables. Take measures to prevent
personal injury or property damage caused by accidental contact with high
voltage or other reasons.
Power cables must be vertically routed into combiner boxes and wiring
terminals to avoid damage caused by horizontal stress on the terminals,
which is not covered under the warranty.
If an inverter has not been running for six months or longer after being
mounted, it may have failed and must be checked and tested by professionals
before being put into operation.
To prevent the inverter from being corroded by moisture, PV terminals that
will not be used for a long time must be sealed with dedicated PV terminal
plugs. Inverter failure due to not using dedicated PV terminal plugs is not
covered under the warranty.
The mounting structure for the inverter must be fireproof. Do not install the
inverter on flammable building materials to avoid personal injury or property
loss caused by fire or other reasons.
Do not install the inverter on flammable building materials.
Ensure that the installation surface is solid enough to bear the weight of the
inverter to avoid personal injury or property loss caused by the collapse of the
mounting structure or other reasons.
In residential areas, do not install the inverter on a drywall or wall made of
similar materials which have a weak sound insulation performance because
the inverter generates noise during operation.
Reserve sufficient clearance around the inverter for installation and heat
dissipation. The inverter provides self-protection in high-temperature
environments. The impact of environment changes on the clearance for heat
dissipation needs be considered during design. The clearance around the
