nothing in the package damages the product . The
followingcontainsincluded: Machine X 1
User Manual X 1
Mains input line X 1
Preparation
Before turning on the device, please reserve a distance of more than 30CM above the
device and to the left and right to ensure for heat dissipation.Input andOutput Connection
1. After power on, you can directly take power from the AC output.
2. DCoutput poweredwithout turned on.
3. Connect the grid and the AC input terminal with the matching wires to load the mains
and charge the battery.
4.Please make sure the cable is firmly connected and do not move the machine while it
is running .
Install Equipment
Taking the following notes into consideration before choosing an installation location:
1. Do not install the inverter on flammable building materials .
2. Pls installit on a sturdy surface .
3. Install this inverter at eye level so that the LCD display
can be read at any time .
4. In order to properly dissipate the air circulation, please
leave a space of about 200mm from the side and about
300mm above the device .
5. To ensure the best operation, the ambient temperature
should be between 0-50 ° C
6. It is recommended to install vertically on the wall
7. Leave a little free space around the inverter, as shown
in the picture to the right, to ensure adequate heat
dissipation and enough space to move the cables

PV Panel Connection
Please choose the appropriate wire according to the matching photovoltaic panel.
PV module selection :
When choosing the right PV module, be sure to consider the following parameters:
1. The open-circuit voltage (VOC) of the PV module does not exceed the maximum open-circuit
voltage of the PV array of the inverter.
2. The open circuit voltage (VOC) of the PV module should be higher than the minimum value of the
cell voltage.
3. The maximum power point voltage of the photovoltaic array should be close to the MPPT optimal
working voltage of the inverter or within the MPPT working voltage range. If a photovoltaic module
cannot meet this requirement, it is necessary to connect the photovoltaic modules in series to meet
the requirements. See the table below.
Follow the steps below to connect the PV module:
I.Remove the 10mm positive and negative conductor insulating sleeves on
the PV inverter.
II.Check that the cable connection between the PV module and the PV input
connector is correct. Then, connect the positive (+) side of the cable to the
positive (+) side of the PV input connector. Connect the negative (-) of the
cable to the negative (-) of the PV input con
