3. Operation mode illustration of the inverter
TRM inverter has five operation modes during the whole work process; they are wait, check, normal,
fault and flash modes. Its detail illustration is shown by Figure 3-1 below.

Figure 3-1 State Machine of Inverter working mode
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 300Vdc 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
