General notes
The Eversol is a transformerless string solar inverter which converts the DC current
of a PV generator to AC current and feed it into the public grid. When you chose it,
you have opted for reliable and powerful technology. With protection class IP65, the
units are ready for use in all environmental conditions, and high efficiency meets
your requirements.

2 Safety instructions and regulations
2.1 Intended use
The Eversol inverter converts the DC power generated by the photovoltaic (PV)
modules into AC power and feed this into the power supply. Eversol inverters are
built according to the safety rules. However, improper use may cause lethal hazard
for the operator, third parties or the units and other property. Meanwhile, any other
or additional and mobile use is prohibited. Alternative use, modifications to the
Eversol or the operation of inverter not expressly recommended by Eversolar New
Energy will invalidate the warranty claims.
2.2 Safety operating instructions
1. The inverters must be installed by an authorized skilled electrician who is
responsible for observing existing standards and regulations. In addition,
opening of the inverter, and any electrical installation, repair or modification of
the inverter may also only be performed by authorized skilled electrician.
2. The Eversol may only be operated with PV generators. Do not connect any
other sources of energy to the Eversol.
3. Some part of the Eversol housing become hot during
operation, and sometimes the temperature can reach 60
℃in normal operation. Don’t touch that part for danger
of burn.
4. Don’t lay flammable and explosive materials close to the system.
5. Be sure that the system is out of the children’s reach.
6. Don’t put any things on the inverter.
7. Before cleaning, disconnect the system from the power grid by opening the AC
breaker and open the DC switch on the PV generator, in order to exclude the
danger of electric shocks. Don’t touch the inverter in five minutes. Use a soft,
dry cloth to clean the system. Never use corrosive, solvent-containing or
abrasive cleaners or polishes.

3.2 LED display
Eversol inverters are equipped with three LEDs including “green”, “red” and
“yellow” which provide information about various operating status in the following
ways.

Operation Instructions 5
Green LED:
The green LED starts to light up once the photovoltaic modules voltage is more than
125 V. The green LED indicates that the inverter is active and working normally. If
this LED does not light up, the inverter can not supply power to the grid. In normal,
this LED begins to light up in the morning when the sunshine intensity is enough
and goes out when it gets dark.
Red LED:
The red LED indicates that the inverter has stopped supplying power to the grid
because of a fault, and the exact fault information will display on the LCD at the
same time. The faults as follows in the table will active the red LED.
Yellow LED:
The yellow LED lights up during the inverter communicating with other devices
including PMU and PC and goes out after the communication finished.

The inverter has a fault, and it
stops feeding. According to the
content which displays on the
LCD, look over the FAQ part to
resolve. If it doesn’t do, contact
your local service. On
elimination of the fault, the
inverter resume and the green
light on.
Yellow
During communicating
The inverter is communicating
with other devices including
PMU and PC.

6 Operating Instructions
3.3 LCD display
A backlight LCD display is integrated in the cabinet of the Eversol inverters so that
it is easily visible. The display consists of 16 characters and 2 lines. The bottom line
(Line 2) always displays the output power (Pac = xxxW). The top line (Line 1)
shows current state information by default, and by pressing function key it will
display different operating information as follows:

3.4 Function key
The Eversol has a function key which is necessary to switch between the different
displays, entering next level and locking.
Press the key once, it displays next information. The menu is continuous, if you are
at the last entry of a menu, the first entry will be displayed on LCD when you press
the key again.
If you don’t press the key for approx. 10 second, it will display the state information
again and keep on.
3.4.1 Setting the Language
The Eversol provides several languages.
At the entry of “SetLanguage”, press the key for approx. 5 seconds, you can enter
the language menu.
Select the language which you require with the function key.
Keep this state without any operation. When it returns to the main menu
automatically, the setting is saved.
3.4.2 LOCK
If you want to freeze the display during normal operation, you can press the key for
a few seconds when it display the entry you desire. Release the key until you see
“LOCK”. Then it always shows the selected entry until you press the key again or
the working state of the inverter changes.
3.4.3 LCD Backlight control
To save power, the backlight of LCD display automatically turns off after 20
seconds. To enable it, press the key again.

4 FAQ (Frequently asked questions)
Sometimes, your PV system does not work properly, we recommend the following
solutions for quick troubleshooting. If there is a fault, the red LED will light up
instead of the green LED.
LCD display
Possible actions
Resumable
Fault
Isolation Fault
1. Check the impedance between PV (+) & PV
(-) and the inverter is earthed. The impedance
must be greater than 2M.
2. Check whether the AC-side has contacts with
earth.
Ground I Fault
1. The ground current is too high.
2. After cut off the AC side connection, unplug
the inputs from the PV generator and check
the peripheral AC system.
3. After the cause is cleared, re-plug the PV
panel and AC connection, and check
PV-Inverter status.
Grid Fault
Fac Over Range
Vac Over Range
1. Wait for a moment, if the grid returns to
normal, PV-Inverter automatically restarts.
2. Make sure grid voltage and frequency meet
the specifications.
Utility Loss
1. Grid is not connected.
2. Check grid connection cables.
3. Check grid usability.
4. If grid is ok, and the problem persists, maybe
the fuse in the inverter is open, please call
service.
Over Temperature
1. The internal temperature is higher than
specified normal value.
2. Find a way to reduce the ambient temperature.
3. Or move the inverter to a cooler environment.

10 Operating Instructions
PV over Voltage
1. Check the open PV voltage, see if it is greater
than or too close to 450VDC (for Eversol-TL
1500AS (1700GB UK version)) or 500VDC
(for Eversol-TL 2000AS (2000GB UK
version)).
2. If PV voltage is less than 450VDC or
500VDC, and the problem still occurs, please
call local service.
Permanent
Fault
Consistent Fault
Disconnect PV (+) or PV (-) from the input, restart
the inverter.
Relay-Check Fail
1. Disconnect ALL PV (+) or PV (-).
2. Wait for a few seconds.
3. After the LCD switches off, reconnect and
check again.
4. If the problems remain please call local
service.
DC INJ High
EEPROM R/W
Fail
SCI Failure
AC HCT Fault
GFCI Failure
If there is no display on the panel, please check that the connection of the inverter
with PV generator and grid are correct. The safety information in this manual must
be fully observed in doing so.
If the PV voltage is higher than 150 V, but the inverter doesn’t work, please call
your local service.
During periods of little or no sunlight, the inverter may continuously start up and
shut down. This is due to insufficient power generated to operate the control circuits.
If the problems remain please call service.
