I-SUNVIMIE4amamotho kagesi akhiqizwa ngokwezinga lamazwe ngamazweI-IEC60034-30-1:2014.Wonke amamotho e-IE4 akhiqizwa nge-silicon yebanga lokuqalainsimbi, ama-harmonics aphansi ukusonga, umsindo ophansifuthiama-bearings aphansi, ukumelana nomoya ophansi kanye nabalandeli bokupholisa umsindo ophansi.Asetshenziswa kakhulu kubalandeli, amaphampu, amathuluzi omshini, ama-compressor, nemishini yokuthutha.Amamotho nawo angasebenza ngokuphepha nangokuzinza emkhakheni wemboni kaphethiloli, amakhemikhali, insimbi, izimayini nezinye izindawo lapho kunomthwalo osindayo kanye nendawo yokusebenza enzima.Izinjini zinganikezwa ibanga lokuvikelaIP55,IP56, IP65, IP66kanye nebanga elingu-F, H, izinga lokushisa elikhuphukayo lebanga B. Amamotho e-SUNVIM IE4 abhaliswe ohlelweni lukazwelonke lwelebula yamandla, futhi athole isitifiketi se-china somkhiqizo wokonga amandla.
