6. Startup and Shutdown
Before starting the inverter, make sure that the inverter can meet the following conditions,
otherwise it may result in fire or damage to the inverter. In this case, we do not undertake
any responsibility. At the same time, to optimize the system configuration, it is recommended
that the two inputs be connected to the same number of photovoltaic modules.
a). The maximum open circuit voltage of each set of photovoltaic modules shall not exceed
����Vdc under any conditions.
b). Each input of the inverter better use the same type of photovoltaic module in series.
c). Total output power of PV shall not exceed the maximum input power of inverter, each
photovoltaic modules shall not exceed the rated power of each channel.
When installing the WiFi stick, tear off the sealing strip on the inverter. Insert the datalogger
into the interface and fix it with a screw. The configuration of the datalogger needs to be
performed after various electrical connections have been completed and the inverter DC
power on. When the inverter is on the DC power, it is determined whether the datalogger is
normally electrified (The LED light shines out of the shell).

7.1 Multiple strings and parallel connection meters
If there’s several inverters in a plant, also it can use �pcs meter to realize zero export function.
For example,if there’s �pcs inverter in the system with �pcs meter.We need to setup �pcs
inverter as the master and others setup as slaves. And, all of them need to connect to the meter
via RS���. Below is the system diagram and configuration of the system.
This application is that when the string inverters work in parallel, there is only one power grid
and one load, and only one meter can be connected to prevent reverse current, so only this
many-to-one anti-reverse current connection can be connected.

When the connection is completed, the following steps should be refered to use this function:
�. Turn on the AC switch.
�. Turn on the DC switch, waiting for the inverter's LCD is turned on.
�. Press Enter button on the LCD panel in the main interface into the menu options, select
[parameter setting] to enter setup submenu, and then select [running parameters] as shown
in picture �.��, at this time please input the default password ���� through pressing the
button [up down, enter], enter the operation parameter setting interface, shown as
picture �.��.

Pic �.�� Zero-export function via energy meter turn on
�. Operate the button [up down], move setting cursor to energy meter and press the button
[enter]. At this time you can turn on or turn off the energy meter by choosing [up down]
button, please press [enter] button to confirm when setting done.
�. Move the cursor to [OK], press [enter] to save the settings and exit the running parameters
page, otherwise the settings are invalid.
�. If set up successfully, you can return to the menu interface, and display the LCD to [home
page] by press the [up down] button. If it displays [meter power XXW], the zero-export
function setting is completed. Shown as picture �.��.
�. 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 or energy meter
wiring conncetion has problem.
�. 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 .

7.3 Notes while using zero export function
For your safety and the operation of limiter function of the inverter, we put forward the follow-
ing 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.
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.
7.4 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 above diagram. 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”.

10.Error informa�on and processing
9. Repair and Maintenance
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.
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.
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.
