1 Safety Precautions
Before beginning your journey, please read these safety precautions in User Manual carefully.
1.1 Personnel Safety
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 th rough this User Manual carefully and master it before any operation.
1.2 The PV Inverter Protection
&
NOTICE
As soon as receiving the PV inverter, please check if it is damaged during its transportation. If
yes, please contact your dealer immediately
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.
c.
Do not remove the anti-dismantle label on the inverter's enclosure because it is the basis for product warranty.
1.3 Installation Safety
&
NOTICE
Please read the User Manual carefully before installing the PV inverter; warranty or liability will
be void from Group Solar if damage is caused by installation faults.
a.
Ensure there is no electronical connections around ports of the PV inverter before installing;
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)

1.4 Electrical Connections
Before installing the inverter, check all electrical ports to ensure no damage and no
short circuit. Otherwise personal casualty and/or fire will occur.
&
DANGER
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, good insulation, and with appropriate specification.
1.5 Operating and Commissioning
&
DANGER
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.
a.
Before getting the permission of electrical power sector in the country/ region, the grid-tied PV inverter cannot start generate
power.
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.
1.6 Maintenance
&
DANGER
4
Power OFF all electrical terminals before the inverter maintenance; strictly comply with the
safety precautions in this document when operating the inverter.
User Manual - Safety Precautions
www.groupgshk.com
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.
1.7 Additional Information

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 Functional Models
2.1.1 Function
This series is a three-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.
The inverter is transformer less. Add an isolation transformer before grounding the
positive/ negative terminal of PV modules (like Thin Film module) for operation.
WARNING
WARNING Do not connect PV modules in parallel to several PV inverters for operation.
2.1.2 Model Description
Figure 2.1 shows a model number of the inverter, using 6K as an example.

2.2 Network Application
2.2.1 Grid-tied PV Power Systems
This series inverter applies to grid-tied PV power systems for industrial/commercial rooftops, fishing/farmers light complementary
power generation systems, and large ground-based power stations. Generally, these series inverters are used to low-voltage grid-
tied PV power system, as shown in Figure 2.2.
