Oku kubaluleke kakhulu kwiinkqubo ze-off-grid, apho i-watt nganye egciniweyo yandisa ixesha lokusebenza kwebhetri.
Amaza okutshintsha aphezulu avumela iimagnethi (ii-inductors, ii-transformers) ukuba zinciphe ngobukhulu, nto leyo enciphisa iindleko. Kuyabonakala ukuba kwiminyaka emibini ezayo, ii-semiconductors ze-wide-bandgap ziya kuba luphawu oluqhelekileyo, kungekhona olokuzikhethela, lwee-inverters ezingaphandle kwegridi.
4. Ukusebenza Ngaphandle Kwegridi Kuguquka ukusuka kwi-"Backup" ukuya kwi-"Resilience Assurance": Into Efunekayo Kwiimeko Ezimbi Kakhulu
Kwiminyaka yakutshanje, iziganeko zemozulu ezimbi kakhulu (iinkanyamba, izivuthuvuthu zekhephu, amaza obushushu) ziye zanda kakhulu eMntla Melika, eYurophu, eMzantsi-mpuma Asia, nakwezinye iindawo, nto leyo ekhokelele ekwandeni okukhulu kokucima kombane okukhulu. Amandla okugcina amandla emveli - afana neejenereyitha ezincinci zepetroli - anengxaki yokugcina amafutha, ingxolo, kunye nemiba yokukhupha umbane. Ngokwahlukileyo koko, ii-inverters ezixutyiweyo ezinomthamo ongaphandle kwegridi kunye nokugcinwa kwebhetri ziyanda ukusetyenziswa ngamakhaya kunye namashishini amancinci njengesisombululo "sokuqinisekisa ukuqina".
Ukuqinisekiswa kokuqina kuthetha okungaphezulu nje kokubonelela ngenkxaso yexeshana ngexesha lokucima. Ikwalawula umgangatho wamandla xa igridi ingazinzile okanye i-voltage itshintsha rhoqo, ukuqinisekisa ukusebenza ngokukhuselekileyo kwemithwalo ebuthathaka. Kwanabasebenzisi abakwiindawo zasezidolophini ezigqunywe kakuhle ngoku bakhetha ii-inverters ezixutyiweyo ezinokukwazi ukutshintsha i-off-grid ukuzikhusela kwiingozi zokucinywa kombane ezingalindelekiyo.
