Pic �.�� Zero-export function via energy meter turn on
�.� Sensor Clamp(optional)
The inverter has integrated export limitation function.The function is to adjust the output of
inverter quickly according to the power of the user and solar panels, prevent the output of
the inverter from being fed to the power grid. This limiter function is optional. If you buy the
inverter with limiter, a current sensor will be included in the package which is necessary for
limiter function.
�. Meter power XXW shows positive means grid is supplying the load, and no power fed into
grid. if meter power shows negative, it means PV energy is being sold to grid.
�. After properly connection is done, wait for inverter starting. If the power of the PV array
meets the current power consumption, the inverter will keep a certain output to counteract
the power of the grid without backflow .

Pic �.�� Sensor Clamp
(The arrow of current sensor
points to the grid)
When you are reading this, we believe that you have completed the connection according
to the requirements of chapter �, if you has been running your inverter at this time, and
you want to use the limiter function, please turn off AC and DC switch of the inverter, and
wait for � minutes until the inverter completely discharged. Then connect the current
sensor to the inverter limiter interface. Make sure they are reliably connected, and the
current sensor should clamp to the live wire of the incoming line. In order to make it easier
for you to use the built-in limiter function of the inverter, we have specifically given the
wiring diagram, as shown in Picture �.��, the red lines connected to the utility grid said wire
(L), blue line shows the zero line (N), yellow green line shows the ground wire (PE). We
recommend installing a AC switch between the inverter outlet and the utility grid, the specs
of the AC switch is determined according to the load capacity. The AC switch we
recommend to connect to the inverter output can refer to Table �.�. If there is no integrated
DC switch inside the inverter you purchased, were commend you to connect the DC switch.
The voltage and current of the switch depends on the PV array you access.

�. [utility power] showing positive means grid power is consuming energy, and there is no
backflow. If [utility power] shows negative, which means there’s excess PV energy flows to
grid or current transformer arrow direction is in wrong direction. Please read more on
chapter �.
- �� -
�.� Notes while using zero export function
For your safety and the operation of limiter function of the inverter, we put forward the
following suggestions and precautions:
Safety Hint:
While the utility power is negative and inverter has no output power, that means
the orientation of the current sensor is wrong, please turn off the inverter and
change orientation of the current sensor.
(when using limiter, the arrow of current sensor points to the grid)
Safety Hint:
Under zero export mode we strongly recommend that the two PV arrays are
formed by the same number of PV panels of the same size, which will make the
inverter more responsive to limit the power.
�.� How to browse the load power of your PV grid-tie plant on monitoring platform?
If you want to browse load power of the system and how much energy (KWH) does it export to
grid(inverter output power is used to power the load firstly and then the surplus energy will
feed into grid). You also need to connect the meter according to Pic �.��. After the connection
completed successfully, the inverter will show the load power on the LCD. But please don’t
setup “Meter ON”. Also, you will be able to browse the load power on the monitoring platform.
The plant setting method as below description.
Firstly, go to the solarman platform(https://pro.solarmanpv.com, this link is for solarman
distributor account; or https://home.solarmanpv.com, this link is for solarman end user
account;) plant home page and click “edit”

�. Repair and Maintenance
��.Error information and processing
��.� Error code
String type inverter doesn’t need regular maintenance. However,debris or dust will affect
heat sink’s thermal performance. It is better to clean it with a soft brush. If the surface is too
dirty and affect the reading of LCD and LED lamp, you can use wet cloth to clean it up.
Inverter has been designed in accordance with international grid tied standards for safety,
and electromagnetic compatibility requirements. Before delivering to the customer the
inverter has been subjected to several tests to ensure its optimal operation and reliability.
If there is any failure,the LCD screen will display an alarm message. In this case,the inverter
may stop feeding energy into the grid. The alarm description and their corresponding alarm
messages are listed Table ��.�.
High Temperature Hazard:
When the device is running, the local temperature is too high and the touch can
cause burns. Turn off the inverter and wait for it cooling, then you can clean and
maintain.
Safety Hint:
No solvent, abrasive materials or corrosive materials can be used for cleaning
any parts of the inverter.
