may install the inverter. For optimum
safety, please follow the steps
described in this manual. Keep in mind that the inverter has two voltage
carrying sides, the PV input and the AC grid.
Disconnecting the inverter:
Always disconnect t
he AC line first! Afterwards disconnect the PV lines.
Note that
the inverter can still be charged with very high voltages at
hazardous levels even when it is disconnected from grid/mains and solar
modules. Wait at least 5 min. before proceeding, after having disconnected
from grid and PV panels.
operating the inverter:
Before connecting the AC grid to the inverter, make sure that the installation
cover is mounted again. The inverter must not be open during operation.
Maintenance and modification:
Only authorized personnel are allowed to repair or modify the inverter. To
ensure

exhaustive.

6User Manual
The person performing work on electrical equipment is responsible for the
safety of persons and property!
Disconnecting
Disconnect all cables supplying voltage to the working place before starting
any work. Please note
that a lack of voltage is no guarantee that
disconnection has been performed.
Protecting against reconnection
Prevent the system from reconnecting by marking, closing or locking off the
work area. Unintentional reconnection may result in severe accidents.
Checking that system is voltage free
Ascertain conclusively by means of a voltage tester that the system is
voltage free. Check all terminals to ensure that the system is voltage free (on
each individual conductor).
Covering adjacent voltage-carrying components and preventing persons
from gaining access to them
Cover up all voltage-carrying system components that can harm you while
working. Make sure that danger areas are clearly marked.
1.6. System Sizing
When dimensioning a photovoltaic system, it must be ensured that the open
circuit voltage of the PV string never exceeds the maximum permissible
input voltage of 1000V DC. The PV string
open circuit voltage during
parallel string operation is 910V. Higher voltages may result in permanent
damage to the inverter.
The selection of PV string output should be based on the optimum utilization of
the invested capital compared to the expected annual energy yield from the system.
This optimization depends on local weather conditions and should be considered
in each individual case.
The inverter incorporates an input power limiting device, which automatically
keeps the power at levels that are safe for the inverter. The limitation depends
mainly on internal and ambient temperatures. The limitation is calculated
continuously and always allows the maximum possible amount of energy to be
produced.
Please use the tool supplied by Trannergy when dimensioning a photovoltaic
system.

3.1. Wait mode
When the input power by solar panel is not enough to let the power module work,
it is at waiting mode. The inverter will wait until the input voltage is above
210Vdc and below 910Vdc, it turn to check mode.
3.2. Check mode
When the inverter is power on, it will check isolation, HCT device, GFCI device,
relay, fan, and soft start automatically in order. This can guarantee the inverter
work normally and turn to normal operation mode.
3.3. Normal mode
When the conditions above are satisfied, inverter will let the BOOST and inverter
module work and turn to normal generating power mode. It will change the solar
energy into electrical energy and fed it into grid based on advanced MPPT
technology in order to absorb solar energy in maximum extent possible. It will also

calculate the generated energy per day/per month/per year automatically, save the
number in EEPROM and the number can be read from the HMI.
3.4. Fault mode
When there are fault during the inverter running, it will stop generating power and
turn to fault mode and display the fault information on LCD. Before do this, it will
store the generated power number into EEPROM automatically. Many not very
serious fault will be cleared after 5s automatically and retry to run. If the serious
fault generated, it will stay in the fault mode until the technical staff to solve the
problem.
3.5. Flash mode
Regardless the inverter running in which mode above, when there is the flash
command, it will turn into flash mode and rewrite the firmware in DSP flash.
3.6. Shut down
When the PV input voltage less than 150Vdc, the PV panel can’t provide energy
enough, so the inverter shut down automatically. When next day come, with the
irradiance increasing, it will run again smoothly if there are no fault occurrence.
