① ON/OFF：Long press to start the machine,Long press to shut down the machine;

② PV indicator: indicator will be on when PV is available, and will be off when PV is not

available. When PV voltage is low, PV indicator will be off after flashing for 1

hour.(The built-in controller has this function.)

③ Main power supply is always bright ,no main power is no bright.

④ Inverter indicator: will be on when working under inverter mode.

⑤PV module parameters: display the current PV module input voltage, current,

power parameters;(The built-in controller has this function)

⑥Displays the mode status of the current machine ;

⑦Battery parameters: display the current battery voltage, the percentage of

capacity parameters;

⑧Mains input: shows the current power state input voltage, frequency parameters;

⑩Load percentage: Displays the current inverter output voltage, frequency parameters;

6 Working Mode of 40KW Inverter

.Working mode GT series IGBT design transformer based solar power inverter has two working mode: DC Priority and AC Priority

6.1. DCPriority The inverter converts DC input current from either the PV panels or battery bank into AC current to supply the loads. When battery voltage is low, the inverter will automatically switch to the main input power (gr/generator) to supply power to the load. The system automatically switches back to AC after the battery are charged again.

(1) PV with battery bank

(2) Battery only

(3) Only AC power

6.2. AC Priority

While the AC input is stable, the inverter works in the bypass to supply power to the load and charges the battery pack at the same time. When the AC input is too high / too low / serious distortion / abnormal frequency / fault, the system will automatically switch to the battery inverter to supply power to the load. Once the AC input has been stabilized, the system will switch back to the bypass mode to supply power to the load automatically.
