User Manual
● Use the original box to repackage the inverter, seal with adhesive tape with the desiccant inside the
box.
● Store the inverter in a clean and dry place, free of dust and dirt. The storage temperature must be
between 40~176°F and humidity should be between 0 to 95%, non-condensing.
● Do not stack more than two (2) 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.
1.7 Storage
If the inverter is not installed immediately, storage instructions and environmental conditions are below:
1.8 Notice for Disposal
This product shall not be disposed of with household waste. They should
be segregated and brought to an appropriate collection point to enable
recycling and avoid potential impacts on the environment and human health.
Local rules in waste management shall be respected .

2.1 Safety symbols
Safety symbols used in this manual, which highlight potential safety risks and important safety
information, are listed below:
WARNING
Symbol indicates important safety instructions, which if not correctly
followed, could result in serious injury or death.
NOTE
Symbol indicates important safety instructions, which if not correctly
followed, could result in damage to or the destruction of the inverter.
CAUTION, RISK OF ELECTRIC SHOCK
Symbol indicates important safety instructions, which if not correctly
followed, could result in electric shock
CAUTION, HOT SURFACE
Symbol indicates safety instructions, which if not correctly
followed, could result in burns.
2.2 General safety instructions
WARNING
Do not connect PV array positive (+) or negative (-) to ground – doing
so could cause serious damage to the inverter.
WARNING
Electrical installations must be done in accordance with local and
national electrical safety standards.
WARNING
To reduce the risk of fire, branch circuit over-current protective
devices (OCPD) are required for circuits connected to the Inverter.
CAUTION
The PV array (solar panels) supplies a DC voltage when exposed to light.
CAUTION
Risk of electric shock from energy stored in the inverter's capacitors.
Do not remove cover until 20 minutes have passed after disconnecting
all sources of supply, and this can only be performed by a service technician.
The warranty may be voided if any unauthorized removal of cover occurs.

User Manual
10
CAUTION
The inverter's surface temperature can reach up to 167°F . To avoid
risk of burns, do not touch the surface when the inverter is operating.
Inverter must be installed out of the reach of children.
WARNING
The inverter can only accept a PV array as a DC input. Using any other
type of DC source could damage the inverter.
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 applications.
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, see power down instruction on page 38 Section 6.2.
2.3 Notice for use
2. Safety & Warning
2.4 Protection Circuitry and Controls
To meet relevant codes and standards, the Solis U.S. three phase inverter line is
equipped with protective circuitry and controls. These include Arc Fault Circuit Interrupter
(AFCI) and Anti-Islanding Protection.
Arc Fault Circuit Interrupter AFCI:
Edition 2011 of the National Electrical Code®, Section 690.11, requires that all PV plants
attached to a building are fitted with a means of detecting and interrupting serial electric
arcs in the PV wiring and array. An electric arc with a power of 300W or greater must be
interrupted by the AFCI in the time specified by UL 1699B. A triggered AFCI fault may only
be reset manually. After clearing the source of the fault, the AFCI can be deactivated via
the inverter front panel interface.
Anti-Islanding Protection:
Anti-Islanding is a condition where the inverter cease to produce power 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 inverter’s operating in parallel and the grid.

3.1 Environmental considerations
3.1.1 Select a location for the inverter
When selecting a location for the inverter, consider the following:
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.
3. Installation
● The temperature of the inverter heat-sink can reach 167°F.
● The ambient temperature and relative humidity should meet the following requirements.
● If multiple inverters are installed on site, a minimum clearance of 32 inches should be kept
between each inverter and all other mounted equipment. The bottom of the inverter should be
at least 32 inches above of the ground or floor (see Figure 3.2 and 3.3).
● The LED status indicator lights and the LCD located on the inverter's front panel should not be
blocked.
● Adequate ventilation must be present if the inverter is to be installed in a confined space.
CAUTION, HOT SURFACE CAUTION, HOT SURFACE
● The load bearing structure shall meet the following requirements.
Made of non-inflammable materials
Max. load bearing capacity ≥ 4
times of inverter weight

3.1.2.1 Consult technical data
Consult the specifications section (section 10) for additional environmental conditions
(protection rating, temperature, humidity, altitude, etc.).
3.1.2.2 Vertical wall installation
This model of Solis inverter should be mounted vertically.
Figure 3.1 Recommended Installation locations
3.1.2.3 Avoiding direct sunlight
Installation of the inverter in a location exposed to direct sunlight should to be avoided.

3.1.2.5 Flammable substances
Do not install near flammable substances. Maintain a minimum distance of three (3) meters
(10 feet) from such substances.
3.1.2.6 Living area
Do not install in a living area where the prolonged presence of people or animals is expected.
Depending on where the inverter is installed (for example: the type of surface around the
inverter, the general properties of the room, etc.) and the quality of the electricity supply, the
sound level from the inverter can be quite high.
3.2 Product handling
Figure 3.4 Handles used to move the inverter shown circled in red
3.1.2.4 Air circulation
Do not install in small, closed rooms where air cannot freely circulate. To prevent overheating,
always ensure that the air flow around the inverter is not blocked.
Please review the instruction below for handling the inverter:
1. The red circles below denote cutouts on the product package.
Push in the cutouts to form handles for moving the inverter around 249lb (see Figure 3.4).
2. Two people are required to remove the inverter from the shipping box. Use the handles
integrated into the heat sink to remove the inverter from the carton (see Figure 3.5).

User Manual
3. Installation
WARNING
Due to the weight of the inverter, contusions or bone fractures could
occur when incorrectly lifting and mounting the inverter. When mounting
the inverter, take the weight of the inverter into consideration. Use a suitable
lifting technique when mounting. When installers are carrying the inverter,
please use 4 handles to secure safety. Lifting force of each handle shall not
exceed 1.5 times of the inverter weight.
In case of using hoisting to lift the inverter, fix the hoisting cable to the hanger shown in the
graph. Please make a reasonable selection of hoisting equipment considering the inverter
weight of 113kg/249lb.
