1.6 Storage
If the inverter is not installed immediately, the following storage
instructions and environmental conditions must be followed
Use the original packing box with the desiccant inside to pack the inverter.
Store the inverter in a clean and dry place, free of dust and dirt. The
storage temperature
must be between -13~176°F and humidity should be between 0 to 95%, non-
condensing. Do not stack more than four (4) inverters high on a single pallet.
Keep the box(es) away from corrosive materials to avoid damage to the inverter
enclosure. Inspect the packaging regularly. If packing is damaged (wet, pest
damages, etc.), repackage
the inverter immediately. Store inverters on a flat, hard surface — not
inclined or upside down. After 100 days of storage, the inverter and carton
must be inspected for physical damage
before installing. If stored for more than 1 year, the inverter needs to be
fully examined and tested by qualified service or electrical personnel before
using. Restarting after a long period of non-use requires the equipment be
inspected and, in some cases, the removal of oxidation and dust that has
settled inside the equipment will be required. Improper use may result in
potential electric shock hazards or burns. This manual contains important
instructions that should be followed during installation and maintenance.
SAVE THESE INSTRUCTIONS This manual contains important instructions for the
following models that shall be followed during installation and maintenance of

4.1 Select a Location for the Inverter
To select a location for the inverter mounting for safe operation and easy
maintenance,the following
criteria should be considered:
WARNING: Risk of fire Despite careful construction, electrical devices can
cause fires.
Do not install the inverter in areas containing highly flammable materials or
gases. Do not install the inverter in potentially explosive atmospheres.
To avoid overheating, always make sure there is enough free space for air
circulation around the inverter . Exposure to direct sunlight will increase
the operational temperature of the inverter and may limit the output power.
Thus it is recommended to protect the inverter against direct sunlight or rain
or snow.
The ambient temperature and relative humidity should meet the following
requirements. Operating Temperature Range: -13°F to 140°F (-25°C to 60°C)
Relative Humidity: 0~95% It is recommended to use a sun shade minimizing
direct sunlight when the ambient air temperature around the unit exceeds
104°F/40°C.

electronic components in the inverter and void the warranty.
Please refer to figure 4.9, The acceptable wire size range is from 12 AWG to 8
AWG, copper conductors only; refer to local code for appropriate wire size.
CAUTION If the PV strings are accidently connected in reverse or inverter is
faulty or not working properly, do not turn off the DC switch. Otherwise it
may cause DC arc and damage the inverter or even lead to a fire disaster.
The correct actions are: Use a DC clampmeter to measure the DC string
current. If it is above 0.5A, please wait for the solar irradiance decrease
until the DC current is below 0.5A. Only after the current is below 0.5A,
then you it is safe to turn off the DC switch and disconnect the PV strings.
In order to completely eliminate the possibility of failure, please disconnect
the PV strings after turning off the DC switch to avoid secondary failures due
to continuous PV energy the next day.
Please note that any damages due to wrong operations are not covered in the

User Manual
5.1 Start-up procedure
To start-up the inverter, it is mandatory that the steps below are followed in
the exact order outlined. 1. Turn the AC switch ON. 2. Turn on any external DC
switches, if the system has any. Then turn the inverter DC switches ON. If the
PV array (DC) voltage is higher than the inverter start-up voltage, the
inverter will turn on. The red DC POWER LED and LCD will be continuously lit.
3. Solis inverters are powered from the DC side. When the inverter detects DC
power that
is within start-up and operating ranges, the inverter will turn on. After
turn-on, the inverter will check internal parameters, sense and monitor AC
voltage, hertz rate and the stability of the grid supply. During this period,
the green OPERATION LED will flash and the LCD screen will show INITIALIZING.
This tells the operator that the inverter is preparing to generate AC power.
4. After the locally mandated delay (300 seconds for IEEE-1547 compliant
inverters), the inverter will start generating AC power. The green OPERATION
LED will light continuously and the LCD screen will show GENERATING.
CAUTION The surface temperature of the inverter can reach up to 75 (167 F).To avoid risk of burns, do not touch the surface of the inverter while it’s operating. Inverter must be installed in a place inaccessible to children.

technician may see a Yellow Alarm LED illuminate. The RED Power LED will stay
lit until dc power is removed. 2. Turn off the AC Switch between Solis
inverter and the Grid to disable AC power
to the inverter. 3. Wait approximately 30 seconds (during this time, the AC
side capacitors are dissipating
energy). If the inverter has DC voltage above the start-up threshold, the red
POWER LED will be lit. Turn the DC switch OFF. 4. Confirm all LED’s switch OFF
(~one (1) minute).
CAUTION Although the inverter DC disconnect switch is in the OFF position and
all the LED’s are OFF, operators must wait five (5) minutes after the DC power
source has been disconnected before opening the inverter cabinet. DC side
capacitors can take up to five (5) minutes to dissipate all stored energy.
If you are not able to resolve the alarm code using the troubleshooting steps,
or if the alarm code you are seeing is not listed, please contact Solis
customer support.
Please also take note of the inverter model number, serial number, and
internal transmitter type.

6.5.8.2 Power Rate Limit This function is used for changing power ramp up
rate. When the inverter initializes or string MPPT changes, the ramp up rate
is limited.
The default setting is stop (disable). The setting range is from 10% to 600%,
This will change the power change rate per minute. If these values are changed
the inverter may not conform to UL 1741 SA or IEEE 1547 standard.

NOTE Positive values indicate the amount of power is allowed to export to the
grid. Negative values indicate a more strict control to limit the export power
in advance thus ensuring exact no power is feeding into the grid.
6.5.11.3 Fail safe ON/OFF This setting is used to give out an alarm (stop
inverter generation as well) when the CT/Meter connection is lost during
operation. It can prevent potential backflow power into the grid when the
system loses control.

Figure 6.46 Set the Fail Safe ON/OFF
It is only mandatory to turn on this function when the inverter is installed
in UK due to the G100 regulation. For other regions, customers can enable or
disable the function as they desire.
NOTE When the failsafe function is ON and CT/Meter is disconnected somehow,
the inverter will stop generation and give “Failsafe” alarm on the LCD. When
the failsafe function is OFF and CT/Meter is disconnected somehow, the
inverter will keep the output power as the last moment when the CT/Meter is
still connected. After a restart, the inverter will output at full power

6.6 Arc fault (AFCI version)
Solis single phase inverters have a built-in AFCI function which can detect an
arc fault within the DC circuit. If the arc fault happens, it can only be
removed manually. During normal operation, if arc fault happens in the DC
circuit, the inverter will stop output and the LCD will show:

7. Maintenance
User Manual
Solis single phase inverter does not require any regular maintenance. However,
cleaning the dust on the heat sink will help the inverter to dissipate heat
and increase its life expectancy. The dust can be removed with a soft brush.
CAUTION Do not touch the inverter’s surface when it is operating. Some parts
of the inverter may be hot and cause burns. Turn off the inverter (refer to
Section 5.2) and wait for a cool-down period before before any maintenance or
cleaning operation.
The LCD and the LED status indicator lights can be cleaned with a damp cloth
if they are too dirty to be read.
NOTE Never use any solvents, abrasives or corrosive materials to clean the
inverter.

8. Troubleshooting
User Manual
The inverter is designed in accordance with the most important international
grid-tied standards and safety and electromagnetic compatibility requirements.
Before delivering to the customer, the inverter has been subjected to several
tests to ensure its optimal operation and reliability.
In case of failure, the LCD screen will display an alarm message. In this
case, the inverter may stop feeding into the grid. The failure descriptions
and their corresponding alarm messages are listed in Table 8.1:
