1.3 TARGET GROUP
Solar energy generation systems, based on photovoltaic modules, nowadays
represent the most suitable solution to reduce the energy consumption
produced by oil and gas.
The solar inverter is a key device in a solar energy system. It performs the
conversion of the variable DC output of the PV modules into a clean sinusoidal
50Hz/60Hz AC current that is then directly applied to the commercial
electrical grid or to a local grid electrical network.
Typically, solar inverter includes communication function to monitor
operating condition, firmware to update and control the grid connection.
Depending on the grid infrastructure, cabled (RS-485, CAN, Power Line
Communication, Ethernet) or cableless (Bluetooth, ZigBee/IEEE802.15.4)
networking options can be used.

DANGER due to electrical shock and high voltage
Do not touch the operating component of the inverter, it
might result in burning or death.
To prevent risk of electric shock during installation and
maintenance, please make sure that all AC and DC
terminals are plugged out.
D touch the surface of the inverter while the
housing is wet, it might lead to electrical shock.
D stay close to the instruments while there are
severe weather conditions including storm, lighting, etc.
Before opening the housing, the SAJ inverter must be
disconnected from the grid and PV generator; you must
wait at least five minutes to let the energy storage
capacitors fully discharged after disconnecting from
power source.
WARNING
·
·

·must only be operated
·
properties
The installation，service ，recycling and disposal of
the inverters must be performed by qualified personnel
only in compliance with national and local standards and
regulations.
Any unauthorized actions including modification of
product functionality of any form may cause lethal
hazard to the operator, third parties, the units or their
property. SAJ is not responsible for the loss and
these warranty claims.
The SAJ inverter with PV
generator. Do not connect any other source of energy to
the SAJ inverter.
Be sure that the PV generator and inverter connect to
the ground in order to protect and persons.
NOTICE
·
Public utility only.
·
；
The PV inverter is designed to feed AC power directly
to the public utility power grid do not connect AC
output of the device to any private AC equipment.
CAUTION
·
·
·
·
The PV inverter will become hot during operation.
Please don’t touch the heat sink or peripheral surface
during or shortly after operation.
Risk of damage due to improper modifications.
Never modify or manipulate the inverter or other
components of the system.
For radiation prevention, do not stay closer than 20cm
to the inverter for any length of time.

·Installing the inverter under strong sunshine is not recommended; the excess
heating might lead to power reduction.
·
·Make sure enough ventilation at installation spot; insufficient ventilation
may affect the operating performance of the inside electronic components,
even shorten the life span of the device.
Installation of the inverter in the vertical direction is recommended.
Tilted backward max.15 degree is allowed.
Never install the device Forward horizontally or even upside down.
For the convenience of checking the LCD display and possible maintenance
activities, please install the inverter at eye level.
Make sure the wall you selected is strong enough to handle the screws and
the weight of the inverter.
Ensure the device is properly fixed to the rear panel.
The ambient temperature of installation site should be between - 25 °C and
+60 °C ( between -13 °F and 140 °F ) .
5.3 SAFETY CLEARANCE
To make sure the ventilation of the installation spot, if there are multiple SAJ
grid-tie solar inverters installed in the same area, the following safety
clearance shall be followed for proper ventilation conditions.
5.4 MOUNTING PROCEDURE
1. Use the rear panel in the package as a drilling template and mark the
positions of the drill holes, as illustrated below.
Sununo-TL1.5K/2K
Sununo-TL3KA/4KA
Sununo-TL4.4K/5K
2. According to the marks, drill 6 holes in the wall (in conformity with position
marked in above picture), and then place expansion tubes in the holes using a
rubber hammer.

4. Carefully attach the inverter to the rear panel according to the position of the
screws.Make sure the backside of the inverter is closely against the rear panel.
When two people transport the inverter, make sure each one use the hand grip in
right position as illustrated in the picture.
5. Pay attention to the four notches cut in both flanks of heat sink (as illustrated
in above picture), which should be placed in corresponding hooks from the rear
panel. Make sure that the heat sink and the rear panel are buckled together and
the inverter is tightly attached to the rear panel. And tighten the screws with
5.9N·m torque.
6. Please carefully check the accessories and original carton to make sure
during the installation every necessary part is used and nothing is missing.
2. There are 2 varistors for and 4 varistors for

5.7 MODULE TECHNOLOGY
SAJ grid - tie solar inverters provide the optimal solution for any module.
Transformerless-type SAJ grid-tie solar inverters are designed for ungrounded
modules, especially for the crystalline silicon photovoltaic modules, such as
monocrystalline silicon and polycrystalline silicon. While the thin-film
modules are not suitable for SAJ transformerless inverters.
5.8 POLLUTION DEGREE
SAJ grid-tie solar inverters comply with the pollution degree 3.

Integrated RCD and RCM
Current Protective Device) and RCM (Residual Current Operated Monitor).
The current sensor will detect the volume of the leakage current and compare it
with the pre-set value. If the leakage current is above the permitted range, the
RCD will disconnect the inverter from the AC load.
The SAJ grid-tie solar inverter will probably cause a DC current in the external
protective earthing conductor. Where a residual current-operated protective
(RCD) or monitoring (RCM) device is used for protection in a case of direct or
indirect contact, only an RCD or RCM of Type B is allowed on the supply side
of this product. Provided an AC current or pulse current is caused in the
external protective earthing conductor, an RCD or RCM of Type AC or Type A
as alternative can be permitted putting into use.

For Sununo – TL 1.5K/2K/3KB/4KB, there is just one MPP Tracker. These
single MPPT inverters require same type module same quantity, identical

For Sununo – TL 3KA/4KA/4.4K/5K, there are two MPP Trackers for the two
string inputs. Unlike the traditional single MPPT inverters which require same

different alignment and tilt, thus can withstand harshest environmental
