Installation position -
• Install on a wall or strong structure capable of bearing weight.
• Install vertically with a maximum incline of +/- 5°.
• Maintain minimum clearance measurements shown.
• Ensure sufcient working area in front of inverter for wiring box access.
• Choose a location that allows unobstructed airow around inverter.
• Position multiple inverters side-by-side, maintaining minimum clearances. Multiple
inverters can also be placed in staggered arrangement.
• Minimum clearances for staggered arrangements include width of inverter plus
additional allowances for inverters arranged above or below.
Environmental checks - See Technical Data,Section
17, to check environmental parameters.
• Maximum operational ambient air temperature
must be considered when choosing location.
Installing the inverter where operating temperatures
exceed specications will result in power derating.
It is recommended the inverter be installed within
specied temperature range.
• Exposure to direct sunlight will increase operational
temperature of inverter and may cause output power
limiting. It is recommended to use a sun shade to
minimize direct sunlight when ambient air temperature
around unit exceeds 104°F/40°C.
• Due to acoustical noise (about 50dBA at 1 m) from
inverter, do not install in rooms where prolonged
presence of people or animals is expected.
If installed indoors, the inverter must be
inaccessible to unqualified persons.
Direct sunlight use caution
Air ow restricted use caution
Side-by-side arrangement
Staggered arrangement
When mounting the TRIO, rst secure mounting bracket to desired location and then
install wiring box followed by inverter unit. When completely tightened wiring box will
move up to meet inverter. It is recommended to employ exible conduit methods to
allow for possibility of inverter removal.
• Using a level, position mounting bracket on wall and use as a drilling template.
• Drill required holes using a drill with 10mm bit.
• Attach bracket to wall with ten wall anchors, 10mm in diameter, found in mounting kit.
• When installed in seismic Zone 3 or higher, the ve center wall anchors must be xed
into a wood/steel wall stud or concrete/masonry wall.
• When installing exible conduit, provide enough conduit to allow for approximately 1”-
1½” of vertical movement between inverter and wiring box.
• Prior to making conductor connections in wiring box, provide enough conductor to allow
for movement of wiring box in nal stages.
• Hook wiring box on bracket by inserting heads of rear screws in bracket slots.
• Remove wiring box front cover 08.
• Loosen connector screws 07 to remove coupling cover 04 and store in pocket at left-rear
of wiring box.
• Locate four bolts protruding from rear of inverter chassis; use as mounting studs and
insert into four associated slots on mounting bracket as shown at right.
• Lift inverter using two people and orient it to bracket so four studs are just above their
associated slots.
NOTE: For easier lifting and handling, an optional lifting kit is available containing
handles and eyebolts that can be attached to holes in side of inverter unit.
• Clamp screw 05 is accessed externally at bottom of wiring box and used to physically
secure wiring box to inverter chassis.
• Push screw 05 upwards until it mates with inverter chassis and thread initially by hand.
• Using a 20mm socket, tighten clamp screw 05 to lift wiring box toward inverter until
mating connectors of wiring box and inverter chassis seat fully.
DO NOT COMPLETELY TIGHTEN AT THIS TIME.
• Once wiring box and inverter are connected via screw 05, push screws 07 upward to
mate with inverter and initially thread by hand.
• Use a 13mm socket wrench to tighten connector screws 07 to at least 13.3-14.75 ft-lbs
(18-20Nm) torque.
• Finish tightening clamp screw 05 to a torque of 13.3 ft-lbs (18Nm).
• Secure bottom of wiring box to wall bracket by tightening machine screw
through bottom locking tab 31 and into bottom hole of mounting bracket.

The inverter commissioning procedure is as follows:
1. Turn the DC disconnect switch in the ON position. If there are two separate external disconnect switches (one for DC and the other for AC), rst close the AC
disconnect switch and then the DC disconnect switch.
2. Once powered, icon b11 comes on to indicate that the voltage from the PV array has reached the Vstart threshold.
For input voltages lower than Vstart, icon b11 remains off, “Waiting Sun” is shown in display area b7 and voltage
and current are present (icons b12 and b13).
3. As soon as “Waiting Sun” conditions are met, the inverter shows the AFD board self-test running. The results are shown in display area b7.
If a problem on the AFD board is detected, the self-test will result in an error. Refer to section 16 below.
4. If there are no irregularities, the grid connection sequence starts. Once all the checks are completed, icon b19 comes on.
During these checks, icon b19 is ashing.
5. Icon b14 ashes to indicate the start-up phase; at the same time icon b15 will come on.
6. Immediately following the grid connection will start. Icon b18 will be displayed in steps until the connection
is complete. After the inverter is connected, the icon b18 will stay “plugged in”.
If there is not sufcient sunlight to connect to the grid, the unit will repeat the procedure until all the parameters controlling connection to the grid (grid
voltage and frequency, conrmation of no ground fault) are within range. During this procedure, the green LED ashes ON and OFF.
15.
Commissioning
For –A models only, the AFD performs a self-test when the system is started. The inverter display shows the results of the self-test in area b7.
• If the self-test results are OK, the inverter will continue to AC grid connection.
• If a potential problem on the AFD board is detected, the self-test will result in error E053.
Refer to the technical manual online for possible solutions to clear the error.
During normal operation the input current is continually measured and analyzed.
• If a DC arc fault is detected during operation, the inverter is disconnected from AC grid and error E050 will be shown on display.
• Press and hold the ESC key for three seconds to clear the E050 error which will start the self-test.
• If self-test results are OK, the inverter will reconnect to the AC grid; if the DC arc fault is still present, the self-test will result in error
E053. Refer to the technical manual online for solutions. The AFD self-test can be manually started anytime using the following procedure:
1. Turn off the inverter (switching off both DC and AC switches),
2. Turn on both the DC and AC switches and wait for display communication of the self-test result.

See section 11 for location of switch a01 on communication card 09 in order to change default.
Parallel Mode -S1, -S1A, -S1B versions without AFD
• Use red jumper cable to interconnect positive terminals (+IN1, +IN2).
• Use black jumper cable to interconnect negative terminals (-IN1, -IN2).
• Plug jumper wires into feeder terminals in positions shown at right.
• Tighten screw on top of each feeder terminal to 53 in-lbs (6 Nm) torque, pull on wire to conrm it
is secure.
Parallel mode -S version without AFD
• Parallel two channels by inserting solid copper
jumpers 12 into DC terminal blocks 13 between
both channels as shown at right.
• One jumper connects POSITIVE input (red) and
second jumper connects NEGATIVE input (black).
• Tighten in place with at least 53 in-lbs (6Nm)
torque.
