The inverter has been constructed according to applicable safety and technical guidelines.
Use the inverter in installations that meet the following requirements ONLY:
1). The inverter must be permanently installed.
2). The electrical installation must meet all the applicable regulations and standards.
3). The inverter must be installed according to the instructions stated in this manual.
4). The system design must meet inverter specifications.
5). The inverter can only be used for industrial.
To start-up the inverter, the Grid Supply Main Switch (AC) must be turned on, BEFORE the DC
Switch is turned on. To stop the inverter, the Grid Supply Main Switch (AC) must be turned off
before the DC Switch is turned off.
2.3 Notice for use
To meet relevant codes and standards, the Solis three phase inverter line is
equipped with protective circuitry and controls.
Anti-Islanding Protection:
Islanding is a condition where the inverter continues to produce power even when the grid
is not present. Circuitry, along with firmware, has been designed to determine if the grid is
present by adjusting the output frequency of the inverter. In the case of a 60Hz resonant
system where the inverter is partially isolated from the grid, the inverter programming can
detect if there is a resonant condition or if the grid is actually present. It can also
differentiate between inverters operating in parallel and the grid.

5.1 Selecting the appropriate grid standard
5.1.1 Verifying grid standard for country of installation
Solis inverters are used worldwide and feature preset standards for operating on
any grid. Although the grid standard is set at the factory, it is essential the grid standard be
verified for the country of installation before commissioning.
The menu for changing the grid standard or for creating a custom standard is accessible as
described in Section 6.7 and below.
WARNING
Failure to set the correct grid standard could result in improper operation
of the inverter, inverter damage or the inverter not operating at all.
5.2 Changing the grid standard
5.2.1 Procedure to set the grid standard
NOTE
This operation is for service technicians only. The inverter is customized
according to the local grid standard before shipping. There should be no
requirement to set the standard.
NOTE
The “User-Def” function can only be used by the service engineer.
Changing the protection level must be approved by the local utility.
1). From the main screen on the display, select ENTER. There are 4 sub-menu options,
use the UP/DOWN arrows to highlight ADVANCED SETTINGS. Press enter to select.
2). The screen will show that a password is required. The default password is "0010",

5.4.1 DC Connections
Verify AC connections.
1). Lightly tug on each AC cable to ensure it is fully captured in the terminal.
2). Visually check for any stray strands that may not be inserted in the terminal.
3). Check to ensure the terminal screws are the correct torque.
5.4.2 AC Connections
5.4.3 DC configuration
5.4.3.1 VOC and Polarity
Verify DC configuration by noting the number of panels in a string and the string voltage.
Measure VOC, and check string polarity. Ensure both are correct and VOC is in specification.
WARNING
Input voltages higher than the maximum value accepted by the inverter
(see “Specifications” in section 10) may damage the inverter.
Although Solis inverters feature reverse polarity protection,
prolonged connection in reverse polarity may damage these protection
circuits and/or the inverter.
5.4.3.2 Leakage to ground
Measure leakage to ground to check for a DC ground fault.
3). Use the UP/DOWN keys to highlight the SELECT STANDARD option. Press enter to
select.

5.3 Setting a custom grid standard
WARNING
● Failure to set the correct grid standard could result in improper operation
of the inverter, inverter damage or the inverter not operating at all.
Only certified personnel should set the grid standard.●
Only set the grid configuration that is approved by your location and ●
national grid standards.

5.4.3.2.1 Detection of leakage to ground
Solis inverters are transformer-less and do not have an array connection to ground.
Any measurement of a fixed voltage between ground and either the positive or negative string
wiring indicates a leakage (ground fault) to ground and must be corrected prior to energizing
the inverter or damage to the inverter may result.
Measure VAC and verify voltage is within local grid standards.
1). Measure each phase to ground (L-G).
5.4.4.1 Measure Vac and frequency
2). Measure phases to the other phases in pairs (L-L). PH A to PH B, PH B to PH C and
PH C to PH A.
3). If the meter is equipped, measure the frequency of each phase to ground.
4). Ensure each measurement is within local grid standards and the inverter specifications
as noted in section 10 “Specifications”.
A phase rotation test is recommended to ensure the phases have been connected in the
appropriate order. Solis inverters do not require aspecific phase rotation connection.
However, the local utility may require a specific phase rotation or a record of the phase
configuration of the installation.
5.4.4.2 Phase rotation test
Verify AC configuration.
5.4.4 AC configuration
5. Commissioning 6. Start and Shutdown
6.1 Start-up procedure
To start-up the inverter, it is mandatory that the steps below are followed in the exact order
outlined.
1). Ensure the commissioning checks in Section 5 have been performed.
2). Switch the AC switch ON.
3). Switch the DC switch ON. If the PV array (DC) voltage is higher than the inverter's
start-up voltage, the inverter will turn on. The red DC POWER LED and LCD will be
continuously lit.
4). 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 supply grid. 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.
5). 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 inverter's surface temperature can reach up to 75℃ (167⁰ F). To
avoid risk of burns, do not touch the surface when the inverter is in
the operational mode. Additionally, the inverter must be installed
out of the reach of children.
6.2 Shutdown procedure
To stop the inverter, it is mandatory that the steps below are followed in the exact order outlined.
1). Switch AC switch OFF.
2). 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. Switch the DC switch OFF.
3). 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.
