The EPIG1K / EPIG2K retrevni seirSe is suitable for indoor and outdoor
use and may only be operated with PV arrays (PV modules and cabling) of protection
class II... Do not connect any sources of energy other than PV modules to the inverter.
Any other use can result in personal injury or property damage.
2.2 Safety instructions
DANGER!
Danger to life due to high voltages in the inverter!
High voltages that can result in electrical shocks are present in the
conductive component parts of the inverter.
All work on the inverter may be carried out by qualified personnel
only.
DANGER!
Danger of burn injuries due to hot enclosure parts.
Do not touch enclosure during operation.
Only touch the lid during operation.
DANGER!
Before opening the housing, the inverter must be disconnected
from the grid and PV generator; while you must wait at least 5
minutes to let the energy storage capacitors fully discharged after
disconnecting from the power sources.
WARNING!
The installation must be performed in full compliance with
national and local standards and regulations.

WARNING!
Grounding the PV Generator
Be sure that the PV generator frame and inverter connect to the
ground in order to achieve maximum protection of the system and
personnel

3.2 Identifying the Inverter
You can identify the inverter by the type label. The type label is on the right side of
the enclosure. The serial number (Serial No.) and the type (Type / Model) of the product,
as well as device-specific characteristics are specified on the type label.

4. Mounting the Device
4.1 Security
DANGER!
Danger to life due to fire or explosion!
• Despite careful construction, electrical devices can
cause fires.
• Do not mount the inverter on flammable construction materials.
• Do not install the inverter in areas where highly
flammable materials are stored.
• Do not install inverters in areas with a risk of explosion.
CAUTION!
Risk of injury due to the heavy weight of the inverter.
• Take the weight of the inverter into account for transport.
• Select a suitable mounting location and mounting surface.
CAUTION!
Danger of burn injuries due to hot enclosure parts!
Mount the inverter in such a way that it cannot be touched
inadvertently.
4.2 Selecting the mounting location
Consider the following requirements when selecting the mounting location:
The mounting method and location must be suitable for the inverter's weight
and dimensions (see section 11 "Technical Data" (page 80)).
Mount on a solid surface.
The mounting location must at all times be clear and safely accessible.
Mount vertically or tilted backwards by max. 15°.
Page 8
6>>
The connection area must point downward.
Never mount the device with a forward tilt...
Never install the device with a sideways tilt.
Do not mount horizontally...
Mount at eye level to allow operating states to be read at all times.
The ambient temperature should be below 40°C to ensure optimum operation.
Do not expose the inverter to direct sunlight as this can cause excessive
heating and thus power reduction.
In living areas, do not mount the unit on plasterboard walls or similar to avoid
audible vibrations. When in use, the inverter emits noises which may be
perceived as a nuisance in a living area.
Observe the following minimum clearances to walls, other devices or objects
to guarantee sufficient heat dissipation and enough space for pulling the
Electronic Solar Switch handle.

4.3 Mounting instructions
Mounting procedures:
a) Drilling holes:
There are holes on the mounting template in the accessory, which is for help of
orientation. Drill four holes for the screws at the selected installation position. The space
between every two holes is shown in the figure below. Keep drilling vertical to the wall
and don’t shake the drill to avoid holes tilting. The depth of the holes must be the same
and 55mm～60mm. After removing the dust in the four holes, measure the net depth of
the holes. If the depth is deeper than 60 mm or less than 55 mm, the wall plugs wouldn’t
be installed and tightened.
b) Wiring the screws
After drilling holes in the wall, place four wall plugs (object2 shown in the left drawing
below) in the holes using a rubber hammer. Then, wiring four screws (object1) into the
wall plugs.
Page 10
8>>
NOTICE
Before inserting wall plugs, measure the depth of every hole and
the distance between every two holes. If the measured values do
not meet the installing requirements, re-drill holes in the wall.
c) Attach the inverter to the screws downwards slightly.

maximum input open circuit voltage does not exceed 450V.
Step 4: Measure DC voltage between positive terminal of the PV string and Earth and
DC voltage between negative terminal of the PV string and Earth. If the two
voltages are constant and not zero, there is an insulation failure somewhere in
this PV string.
Step 5: Plug DC positive and negative connector into corresponding terminals. If it
makes a click sound, it means DC connector has attached to terminals.
5.5 Connecting the inverter to the grid
5.5.1 AC output wiring
Step 1: Unscrew AC output cover at the downside of the machine.
Page 16
14>>
Step 2: Insert stripped AC cables of appropriate size into the cable glands. Fix the phase
cables into corresponding terminals with screwdriver according to marks. Fix ground
cable into the ground terminal.
Step 3: Screw the AC output cover.
Page 17

Page 19
<<17
5.6.2 Monitor system connection
The inverter provides RS485 interface to communicate with remote PC. User can
monitor the state of the inverter and observe current running information and history
record via this interface. Below is the method to install the monitoring system.
6. Switch on and off
6.1 Switch on
1. Finish the installation of the PV array, AC grid and the inverter according to the
introduction before.
2. Before switch on, checking whether AC voltage and DC voltage can meet the
requirement of the inverter
3. Switch on the DC breaker at first.
4. Then switch on the AC breaker.
5. When the environment conditions allow the inverter to work, the inverter will
automatically start up and connect the grid to generate power.
6. After the inverter works normally on grid, it can be left working itself without human
control. It can shut down when fault occurs and it can start automatically after the fault is
gone.
6.2 Switch off
1. When solar power was not enough to generate the power, the inverter will shut down
automatically.
2. If you need to shut down the inverter yourself, you can operate the inverter through the
front panel screen.
3. The process of emergency shutdown.
If you need shut down the inverter in emergency, first turn off the AC breaker, then turn
Page 20
18>>
off the DC breaker, otherwise it may lead to the damage of the DC breaker and danger to
people. If any damage or loss occurs due to not following this requirement, we will not
follow the warranty.

The PV inverter is equipped with two LEDS including “green” and “red” which indicate
three different modes of operation.
Green LED: Normal mode
The green LED lighting indicates that the inverter is active and working normally.
B A C
Page 21
<<19
Whenever the supplied power from PV panel is sufficient (voltage>120VDC), Inverter
converts power to the grid. If the power is insufficient (voltage<90VDC), the inverter
enters a “waiting” state.
Red LED: Fault mode
The red LED indicates that the inverter has stopped feeding power into the grid because
of fault, and the corresponding fault information will display on the LCD at the same time.
All off: Shutdown mode
During peri
ods of little or no s
unlight, Inverter automatically stops running. In this mode,
Inverter does not take any power from the PV panels. The display and LED’s on the front
panel do not work.
7.3 LCD display
The LCD display consists of 16 characters and 2 lines. Once the PV power is sufficient,
the inverter starts up automatically. The inverter displays information as shown in the
flow chart as follow:
“Welcome” “Model: EPIG X K ” “Version
: x.xx” “ Waiting: xxS” “Normal State”
“Pac= xxx.x W”.
To save power, the LCD display’s backlight automatically turns o after feeding the grid 5
minutes. If there is a fault message appears, the LCD display’s backlight t urns on all the
time until the fault is solved.
