4
1. Connect the assembled AC cables to AC terminals with a fastening torque of
approximately 2.0-2.5 Nm.
Note: (If the inverter has backup function) Connect the backup terminals before connecting the on-
grid terminals. Make sure they are not connected to the wrong side.
2. Lock the cover and screw on the cap.
Use a screwing
torque of 2.0–
2.5Nm.
Special adjustable settings
The inverter has a eld where the user can set functions, such as trip points, trip time, time of
reconnection, active and invalid of QU curve, and PU curve. These functions can be adjusted by
using special software. If interested, please contact the after-sales department.
Declarations for the backup function
The back-up output of inverters have over load ability.
For details please refer to the technical parameters of the inverter section.
And the inverter has self-protection derating at high ambient temperature.
The below statement lays out general policies governing the energy storage inverters.
1. For Hybrid inverters, the standard PV installation typically consists of the connection of the
inverter with both panels and batteries. In case of systems not connected to the batteries,
the Back-Up function is strongly not advised to use. GoodWe shall not cover the standard
warranty and be liable for any consequences arising from users not following this instruction.
2. Under normal circumstances, the Back-Up switching time is less than 10 ms (the minimal
condition to be considered as the UPS level). However, some external factors may cause the
system to fail on Back-Up mode. As such, we recommend the users to be aware of conditions
and follow the instructions as below:
• Do not connect loads if they are dependent on a stable energy supply for a reliable
operation
• Do not connect the loads which may in total exceed the maximum Back-Up capacity
• Try to avoid those loads which may create very high start-up current surges such as
Inverter Air-conditioner, high-power pump etc.
• Due to the condition of battery itself, battery current might be limited by some factors
including but not limited to the temperature, weather etc.
Acceptable loads are shown below:
The inverters are able to supply over load output at it's Back-Up. For details please refer
to the technical parameters. And the inverter has self-protection derating at high ambient
temperature.
• Inductive Load: 1.5P non-frequency conversion air-conditioner can be connect to back-up
side. Two or more non-frequency conversion air-conditioner connect to Back-Up side may
cause UPS mode unstable.
• Capacitive Load: Total power <= 0.6 x nominal power of model. (Any load with high inrush
