( 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%.

( h ) the pcu shall have a higher degree of ingress protection of ip 65 to handle robust environment conditions from dust and water ingress under complete outdoor installations. ( i ) the data logger should possess the feature of extracting the data externally with open protocols like modbus tcp / rtu. the manufacturer should provide the modbus register mapping file to utilise this feature ( j ) specifications: ( i ) nominal voltage 230v / 415v ( ii ) voltage band between 80% and 110% of v nominal, pollution degree iv ( ii ) nominal frequency 50 hz saftey class ( iv ) operating frequency range 47.5 to 50.5 hz ( v ) waveform pure sine wave ( vi ) harmonics ac side total harmonic current distortion < 3% 10 minimum requirement and specification for on grid inverter ( contd / ... ) : ( vii ) ripple dc voltage ripple content shall be not more than 1% ( viii ) casing protection levels degree of protection: min ip 65 ( ix ) operating ambient temp range: 10 to + 60 degree celsius ( x ) rh : 0 100% non condesing ( k ) protections: ( i ) reverse polority protection ( ii ) over voltage: both input and output ( iii ) over current: both input and output ( iv ) over / under grid frequency ( v ) over temperature ( vi ) short circuit ( vii ) lightning ( viii ) surge voltage induced at output due to external source ( ix ) islanding ( x ) ingress protection ip 65 ( l ) communication interface : rs485 / rs232 / wi fi ( with or without usb ) ( m ) synchronization: photovoltaic system must be equipped with a grid frequency synchronization device, if the system is using synchronizer inherently built in to the inverter then no separate synchronizer is required ( n ) dc injection: photovoltaic system shall not inject dc current greater than 0.5% of full rated output at the interconnection point or 1% rated inverter output current into distribution system under any operating conditions.
