1 Safety Precautions
Before beginning your journey, 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.
c. Do not remove the anti-dismantle label on the inverter’s enclosure because it is the basis for
product warranty.
1.2 The PV Inverter Protection
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)
1.3 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 void from Senergy if damage is caused by
installation faults.

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.
1.4 Electrical Connections
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.
1.5 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.

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
To avoid any other unforeseeable risk, contact Senergy immediately, if
there is any issue found during operation.

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 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.
2.1.2 Model Description
Figure 2.1 shows a model number of the inverter, using 6K as an example.

2.1 Functional Models
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.
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.
