Kugeza ubu, sisitemu ya 800V iracyafite ibibazo byinshi mu biciro, ikoranabuhanga n’ibikorwa remezo.Izi ngorane ninzira yonyine yo guhanga udushya no guteza imbere ikoranabuhanga rishya ryimodoka ninganda.icyiciro.
Amasosiyete yimodoka yo mubushinwa, hamwe nubushobozi bwayo bwihuse kandi bunoze bwo gukoresha injeniyeri, arashobora kubona umubare munini wibikorwa byihuse bya sisitemu 800V, kandi agafata iyambere mukuyobora icyerekezo cyikoranabuhanga mubijyanye n’imodoka nshya zingufu.
Abaguzi b’abashinwa nabo bazaba abambere kwishimira ubunararibonye bwimodoka nziza yazanywe niterambere ryikoranabuhanga.Ntabwo bikiri nko mugihe cyibinyabiziga bya lisansi, mugihe abaguzi bo murugo bagura moderi zishaje mumasosiyete mpuzamahanga yimodoka, ikoranabuhanga rya kera cyangwa ikoranabuhanga ryibicuruzwa.
