1.3.3 GlossaryACAbbreviation for "Alternating Current”DCAbbreviation for "Direct Current”EnergyEnergy is measured in Wh (watt hours), kWh (kilowatt hours) or MWh (megawatt hours). The energy is the power calculated over time. For example, your inverter operates at a constant power of 4600 W for half an hour and then at a constant power of 2300 W for another half an hour, it has fed 3450Wh of energy into the power distribution grid within that hour.PowerPower is measured in W (watts), kW (kilowatts) or MW (megawatts). Power is an instantaneous value. It displays the power your inverter is currently feeding into the power distribution grid.Power ratePower rate is the radio of current power feeding into the power distribution grid and the maximum power of the inverter that can feed into the power distribution grid.Power factorPower factor is the ratio of active power or watts to apparent power or volt amps. They are identical only when current and voltage are in phase then the power factor is 1.0. The power in an ac circuit is very seldom equal to the direct product of the volts and amperes. In order to find the power of a single phase ac circuit the product of volts and amperes must be multiplied by the power factor.PVAbbreviation for photovoltaic.Wireless communicationThe external wireless communication technology is a radio technology that allows the inverter and other communication products to communicate with each other.The wireless communication device is not standard.

Fig 9.19.2 OLED display wake up8 Working Mode8.1 Normal modeIn this mode, the inverter works normally.ØWhen the DC voltage is greater than 250V, the energy is sufficient, and the grid voltage frequency meets the grid-connected requirements, the inverter will convert the energy of the solar panels into AC power and export to the grid, and the green LED will light up.ØWhen the DC voltage is lower than 180V, the inverter will automatically disconnect from the grid and exit the normal operation mode. When the input voltage reaches the requirement again and the grid voltage and frequency return to normal, the inverter will automatically connect to the grid.8.2 Failure modeThe inverter controls the chip monitors and adjusts the state of the system in real time. When the inverter monitors any unexpected conditions,such as system failure and inverter failure,the display will show the fault information.In the failure mode,the inverter will indicate The leaves of the window will turn red and the inverter output will be disconnected from the grid.When the sunlight is weak or there is no sunlight,the inverter will automatically stop running.When in shutdown mode,the inverter basically does not consume energy from the grid or solar panels,and at the same time,the inverter's display screen and LED lights will be turned off.8.3 Shutdown mode
