2.Safety Instructions
2.3 Notice For Use
The inverter has been constructed according to the applicable safety and technical
guidelines. Use the inverter in installations that meet the following sepcification ONLY:
1. Permanent installation is required.
2. The inverter must be connected to a separate grounded AC group, to which no other
electrical equipment is connected.
3. The electrical installation must meet all the applicable regulations and standards.
4. The inverter must be installed according to the instructions stated in this manual.
5. The inverter must be installed according to the correct technical specifications.
6. To startup the inverter, the Grid Supply Main Switch (AC) must be switched on, before
the solar panel's DC isolator shall be switched on. To stop the inverter, the Grid Supply
Main Switch (AC) must be switched off before the solar panel's DC isolator shall be
switched off.
CAUTION:
The PV array (Solar panels) supplies a DC voltage when it is exposed to light.
CAUTION:
Risk of electric shock from energy stored in capacitors of the Inverter. Do not
remove cover until 5 minutes after disconnecting all sources of supply. Service
technician only. Warranty may be voided if any unauthorized removal of cover.
CAUTION:
The surface temperature of the inverter can reach up to 75℃ (167 F).
To avoid risk of burns, do not touch the surface when inverter is operating.
Inverter must be installed out the reach of children.
WARNING:
To reduce the risk of fire, branch-circuit over-current protective devices
(OCPD) are required for circuits connected to the Inverter.
The recommend rated trip current for AC breaker should be 25A for
SOLTARO-3P5K,SOLTARO-6K inverter, 32A for SOLTARO-10K,
SOLTARO-15K, SOLTARO-20K-HV inverter.
CAUTION:
Risk of electric shock. Do not remove cover. There is no user serviceable
parts inside. Refer servicing to qualified and accredited service technician.

4. Installation
4.1 Select a Location for the Inverter
3.3 Keypad
3.4 LCD
There are four keys in the front panel of the Inverter(from left to right):
ESC, UP, DOWN and ENTER keys. The keypad is used for:
Scrolling through the displayed options (the UP and DOWN keys);
Access to modify the adjustable settings (the ESC and ENTER keys).
3. Overview
The two-line Liquid Crystal Display (LCD) is located at the front panel of the Inverter,
which shows the following information:
Inverter operation status and data;
Service messages for operator;
Alarm messages and fault indications.
.8. .9.
To select a location for the inverter, the following criteria should be considered:
Figure 4.1 Recommend Installation place
To avoid over heating ambient air temperature MUST be considered when choosing the
inverter installation location. SOLTARO recommends using a sun shade minimizing direct
sunlight when the ambient air temperature around the unit exceeds 104°F/40°C.
Do not install in small closed spaces where air can not circulate freely. To avoid
overheating, always make sure the flow of air around the inverter is not blocked.
Exposure to direct sunlight will increase the operational temperature of the inverter and
may cause output power limiting. SOLTARO recommends inverter installed to avoid
direct sunlight or raining.

For 1 or more inverter installed, a minimum 12in clearance should be kept between
each inverter or other object. The bottom of the inverter should be 20in clearance to
the ground.
Visibility of the LED status indicator lights and the LCD located at the front panel of
the inverter should be considered.
Adequate ventilation must be provided if the inverter is to be installed in a confined space.
NOTE:
Nothing should be stored on or placed against the inverter.

4. Installation4. Installation
Inverter should be mounted in a vertical position as shown in Figure 4.3. The steps to
mount the inverter on the wall are given as follows:
1. Locate the wall studs in the desired location and align the wall mount bracket over
the studs. Mark the mounting holes. For masonry walls, the mounting holes should be
for a suitable dynabolt type mounting system.
2. MAKE SURE BRACKET IS horizontal. Ensure that the A, B, C, and D mounting holes
(in Figure 4.3) are aligned with the wall's most secure points (e.g. wall studs in case of
clad building materials).
4.2 Mounting the Inverter
Please use suitable fixings for wall type (e.g. use dynabolts for brick, masonry, etc).

WARNING:
Bracket must be mounted vertically on a vertical wall surface.

3. Carefully hang the inverter on the upper part of the wall mount bracket by fitting the
hooks into the slot of the bracket. Use stainless steel screws at holes E and F
(in Figure 4.4) to secure the mounting hooks to the rear of the inverter.
Figure 4.4 Wall Mount Bracket
The electrical connection of the inverter must follow the steps listed below:
Switch the Grid Supply Main Switch (AC) OFF.
Switch the DC Switch OFF.
Before connection, please make sure the polarity of the output voltage of PV array
matches the“DC+”and “DC-”symbols.
Before connecting inverter, please make sure the PV array open circuit voltage is
within the limit of the inverter
Please don’t connect PV array positive or negative pole to the ground, it could
cause serious damages to the inverter

5.1 Start the Inverter
To start up the Inverter, it is important that the following steps are strictly followed:
1. Switch the Supply Main Switch (AC) ON first.
2. Switch the DC Isolator ON.
3. When both the DC and the AC grid sides supply to the inverter, it will be ready to
generate power. Initially, the inverter will check both its internal parameters and the
parameters of the AC grid, to ensure that they are within the acceptable limits. At the
same time, the green LED will flash and the LCD displays the information of
INITIALIZING.
4. After 30-180 seconds (depending on local requirement), the inverter will start to
generate power. The green LED will be on continually and the LCD displays
GENERATING.
WARNING:
Do not touch the surface when the inverter is operating. It may be
hot and cause burns.
5.2 Stop the Inverter
To stop the Inverter, the following steps must be strictly followed:
1. Switch the Grid Supply Main Switch (AC) OFF.
2. Wait 30 seconds. Switch off the DC switch or pull out the DC input cable. All the LEDs of
the inverter will be off in a minute.
5. Start & Stop
The inverter can be monitored by Wi-Fi or GPRS functions. All the communication functions are
optional (Figure 4.18), please refer to communication connection instructions.
For inverter connect with DRM, please connect communication cable or device to DRM COMM port.

6. Operation 7. Maintenance
SOLTARO three phase inverter does not require any regular maintenance. However, clean
the heat-sink will help inverter dissipating heat and increase the life time of inverter.
The dirt on the inverter can be cleaned with a soft brush.
CAUTION:
Do not touch the surface when the inverter is operating. Some parts may be hot
and cause burns. Turn OFF your inverter (refer to Section 5.2) and let it cool
down before you do any maintenance or cleaning of inverter.
The LCD and the LED status indicator lights can be cleaned with cloth if they are too
dirty to be read.
NOTE:
Never use any solvents, abrasives or corrosive materials to clean the inverter.
8. Trouble Shooting
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:
