( b ) if the power evacuation goes on till the evening the inverter should keep on getting the desired solar power which is in excess of the power needed to operate the inverter itself. as soon as it attains the power which is just sufficient to run the inverter, the power evacuation stops and only the inverter keeps running till the power drops further low due to decreasing sunlight in the evening, resulting in the inverter going to sleep mode to initialize again automatically the next morning. ( c ) a record shall be maintained with input from inverter in the event of failure of the utility grid resulting in inverter going to sleep mode and stop generating power. ( d ) the pcu / inverters should be tested from the mnre approved test centros / nabl / bis / iec accredited testing calibration laboratories.+c50:c59c50:c61c50:c62c50:c61c50:c60c55c50:c57c50:c59c50:c60c50:c61 ( e ) inverter manfacturer should supplied and installed minimum of 10 mw cumulative capacity of inverter in last 5 years in india ( f ) minimum efficiency 98.5%.
