2.1 Intended Use
The Suntrio-TL series inverters are PV inverter which converter the direct current of a PV array
into alternating current and feed this into the electricity grid.
The inverters are designed according to the safety rules. However, improper use, alteration or
modication may cause lethal hazards for the operator or third parties, or may result in damage
to the units and other property. SAJ is not responsible for the loss and invalidate these warranty
claims.
Figure 2.1 Grid-tie Solar System with Suntrio inverter
2.2 Safety Precaution
DANGER
● 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.
● Do not touch the surface of the inverter while the housing is wet, it might lead to electrical shock.
● Do not stay close to the inverters 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
●
The installation, service, recycling and disposal of the inverters must be performed by qualied
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 deny these warranty claims.
● Suntrio inverters must only be operated with PV generator. Do not connect any other source of
energy to the inverters.
● Be sure that the PV generator and inverter are well grounded in order to protect properties and
persons.
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 modications.
● Never modify or manipulate the inverter or other components of the system.
NOTICE

4.2 Mounting Instructions
Figure 4.2 Mounting Instructions
Mounting on a solid surface out door or indoor.
● Site altitude is less than 2,000m above the sea level.
● The mounting location must be clear and safely accessible at all times without the use
of additional aids such as scaffolding or lifting platforms. If this is not the case, service
work may be restricted.
● Mount vertically or tilted backwards by max. 15°
● The connection area must point downwards.
● Never install the inverter forward tilt, sideways tilt, horizontally or even upside down.
● Install the inverter at eye level for convenience checking the LCD display and possible
maintenance activities.
● Given the weight of the device, this will facilitate disassembly for service work.
● The ambient temperature should be below 45°C to ensure optimum operation. Choose
locations with sufcient air exchange. Ensure additional ventilation, when necessary.
● Do not expose the inverter to direct solar irradiation as this could cause power
derating due to overheating.
● In order to avoid audible vibrations in living areas, do not mount the unit on
plasterboard walls or similar.
● Observe the recommended clearances to walls, other inverters or other objects, as
shown in the follow diagram. That ensures sufcient heat dissipation and gives you
enough space to unplug the PV Connector, communication port and operate the DC-
switch.

5.4 Miniature circuit breaker
DANGER
When more than one inverter is connected in parallel to the same miniature circuit-breaker, the
protective unction of the miniature circuit-breaker is no longer guaranteed. This could result in
a cable re or destruction of the inverter.
●
Never connect several inverters to a single miniature circuit-breaker.
In order to securely disconnect the inverter from the PV generate and the public-Grid, SAJ
recommend to install circuit breaker at DC Input and AC output as gure 2.1 shown.

5.5 Connecting the Electricity Grid (AC)
5.5.1Conditions for the AC Connection
You must comply with the connection requirements of your network operator
.
Residual Current monitoring
The inverter is equipped with an integrated all-pole-sensitive residual-current monitoring unit.
The inverter can automatically differentiate between residual currents and normal leading leakage
currents.
If an external RCD or residual-current device (RCMU breaker) is strictly required, you must use
a switch that trips at a residual current 100mA≤ Ifn ≤300mA.
The external RCMU breaker should be installed between inverter and Grid. No load should not
connected to the inverter directly.
Connection of a Second Protective Conductor
In some installation countries, a second protective conductor is required in order to prevent a
contact current in the event of failure of the original protective conductor.(See section 5.5.3)
IEC standard 62109 requirements:
• Installation of the protective earthing conductor at AC terminal with a cross-section of at least
10mm2 (copper), or 16mm2 (aluminum).
UTE C15-712-1:2010 requirements:
• The inverter body conductive accessories must be connected to the equipotential bonding
via a conductor with a minimum cross-section of 6mm² Cu or equivalent and to the protective
conductor at AC terminal.
5.5.2 AC Connection procedure
1)Strip the cable with the length 12mm, be careful NOT to nick conductors.
User Manual
19
2)Please insert the striped cable into bootlace ferrule and crimp the contact.
3)Screw off the AC cover and insert the 5 wires into AC cover assembly with the following
sequence.
4)Release the ve screws at the cable terminal. Then route the 5 wires into the cable terminal
according to the marks on the front case while L1(R), L2(S), L3(T) represent 3 Live line, N
represent Neutral line and PE is ground.
NOTE:
• The PE conductor must be 5 mm longer than the L and N conductor.
• L and N must not be swapped.
• The direction of rotation of L1, L2 and L3 is not relevant.
User Manual
20
5)Screw the cap nut of the cable tightly.
5.5.3 Connecting the Second Protective Conductor
If required by the installation, the earth terminal can be used to connect a second protective
conductor or as equipotential bonding.
Procedure
Take out parts from the packing and insert the earthing wire to “PE” terminal located at the right
of the inverter, then tighten the screw.

include the male side and female side as showed below:
Male side connector (M) Female side connector (F)
Assembly Instructions:
1)Strip the cable with the length of 0.276 inches (9/32”)-(7mm) and please be careful NOT to
nick conductors.
2)Use specied strip tool in this step. Adjust the strip stopper and put the cable in corresponding
notch to strip the length of 7mm.

7.Recycling and Disposal
To comply with European Directive 2002/96/EC on waste Electrical and Electronic Equipment
and its implementation as national law, electrical equipment that has reached the end of its life
must be collected separately and returned to an approved recycling facility. Any inverter that you
no longer required must be returned to your dealer or you must nd an approved collection and
recycling facility in your area.
Ignoring this EU Directive may have severe affects on the environment and your health.
