1 Safety Precautions
Before using the product please read these safety precautions in User Manual carefully, .
a. The PV inverter must be installed electronically connected operated and maintained through, ,
specially trained technician;
b The qualified technician must be familiar with the safety regulations of electrical system. ,
working process of PV power generation system, and standards of local power grid;
c. The technician must read through this User Manual carefully and master it before any operation.
1 1 Personnel Safety.
a Do not tamper with any warning signs on the inverter enclosure because these signs contain.
important information about safe operation.
b Do not remove or damage the nameplate on the inverter’s enclosure because it contains.
important product information.
1 2 PV Inverter Protection.
a Ensure there is no electronical connections around ports of the PV inverter before installation. ;
. .b Adequate ventilation must be provided for inverter installation location Mount the inverter in
vertical direction, and ensure that no object is put on the heat sink affecting the cooling. (For
details, refer to Chapter 4 Installation)
1 3 Installation Safety.
As soon as receiving the PV inverter please check if it is damaged,
during its transportation If yes please contact your dealer immediately. , .
Please read the User Manual carefully before installing the PV inverter;
warranty or liability will be exempted from the company if damage is
caused by installation faults.

U er ManualsSafety Precautions
a Input terminals of the PV inverter apply only to input terminals of PV String do not connect. ;
any other DC source to the input terminals.
b Before connecting PV modules ensure that is its voltage is within the safe range when. , ;
exposed to any sunlight, PV modules can generate high voltage.
c All electrical connections must meet the electrical standards of the country or region. .
. , ,d Cables used in electrical connections must be well fixed under good insulation and with
appropriate specification.
1 4 Electrical Connections.
A. Before getting the permission of electrical power authority in the country/region, the grid-
tied PV inverter cannot start power generation.
b Follow the procedures of commissioning described in the user manual when commissioning.
the PV inverter.
c Do not touch any other parts surface except the DC switch when the PV inverter is operating. ' ;
its partial parts will be extremely hot and can cause burns.
1 5 Operating and Commissioning.
1 6 Maintenance.
Before installing the inverter check all electrical ports to ensure no,
damage and no short circuit Otherwise personal casualty and or fire. /
will occur.
While the inverter operating high voltage can lead to an electrical,
shock hazard and even cause personal casualties Therefore, . ,
operate the PV inverter strictly according to the safety precautions in
the user manual.
Power OFF all electrical terminals before the inverter maintenance;
strictly comply with the safety precautions in this document when
operating the inverter.

WARNING
U er ManualsSafety Precautions
a For personal safety maintenance personnel must wear appropriate personal protective. ,
equipment (like insulation gloves and protective shoes) for the inverter maintenance.
b Place temporary warning signs or erect fences to prevent unauthorized access to the.
maintenance site.
c Follow the procedures of maintenance stipulated in the manual strictly. .
. ;d Check the relevant safety and performance of the inverter rectify any faults that may
compromise the inverter security performance before restarting the inverter.

2 Overview of the Inverter
This chapter introduces the inverter and describes its functional model network application, ,
, , .appearance dimensions and working process etc
2 1 1 Function. .
This series is a single-phase grid-tied PV string inverter transformer less that converts the DC( )
power generated by PV strings into AC power and feeds the power into power grid.
Figure 2 1 shows a model number of the inverter using 3K as an example. , .

Power class code
Figure 2 1 Model number descriptions.
2 1 Functional Models.
The series applies to grid-tied PV power systems for outdoor power stations. Typically, a grid-tied
PV power system consists of PV modules, grid-tied inverters, AC distribution units, and low-voltage
power grid, as shown in Figure 2.2.
2 2 Network Application.
The inverter is transformerless Add an isolation transformer before.
grounding the positive negative terminal of PV modules like Thin/ (
Film module for operation) .
Do not connect PV modules in parallel to several PV inverters for
operation.
