5 Inverter Display and Indicators continued... 5.3 Normal operation Information of normal operation is split into groups of Operating Status; Statistical Information and Operating Mode Information. The Operating status is used to display the main operating parameters of the inverter. The Statistical Information parameter shows total operating time, daily generation and total power generation . -
Page 13: System Operating Modes
5.4 System operating modes There are 4 operating modes as follows: 1) STAND-BY MODE The system is energised but hasn’t met the requirements to generate power (too little sunlight/small DC voltage) or the equipment has not entered generation status after restart. See Figure 14. Figure 14: Stand-by mode 2) INTERRUPTED MODE The system has shut down because of... -
