Njengoko iinkqubo zokugcina amandla ezindlini ziya zithandwa kakhulu, ziqinisekisa ukhuseleko kunye nokusebenza kweengcingo zabo, ngokukodwa kwi-DC-side, kubaluleke kakhulu. Uqhagamshelwano oluthe ngqo lwangoku (DC) phakathi kweephaneli zelanga, iibhetri, kunye nee-inverters zibalulekile ekuguquleni amandla elanga abe ngumbane osebenzisekayo kunye nokuwugcina ngokufanelekileyo. Esi sikhokelo sinika amagqabantshintshi okuqwalaselwa okuphambili, iindlela ezingcono, kunye neempazamo eziqhelekileyo ukuphepha xa ufaka kunye nokugcina i-DC-side wiring yoqhagamshelwano kwii-inverters zokugcina amandla endlu.
Ukuqonda i-DC-Icala lee-Inverters zoGcino lwaMandla eKhaya
I-DC-icala le-inverter yokugcina amandla kulapho umbane wangoku othe ngqo uhamba phakathi kweephaneli zelanga kunye nebhanki yebhetri ngaphambi kokuba uguqulwe ube ngumsinga otshintshisayo (AC) wokusetyenziswa ekhaya. Eli cala lenkqubo libalulekile kuba lilawula ngokuthe ngqo ukuveliswa nokugcinwa kwamandla.
Kulungiselelo oluqhelekileyo lwamandla elanga, iiphaneli zelanga zivelisa umbane weDC, ohamba ngeentambo kunye nezinye izinto ukutshaja iibhetri. Amandla agciniweyo kwiibhetri akwimo yeDC. I-inverter ke iguqula lo mbane we-DC ugciniweyo ube ngumbane we-AC ukubonelela ngezixhobo zasekhaya.
Amacandelo aphambili e-DC-side abandakanya:
Iintambo zeSolar PV ezithutha umbane ukusuka kwiipaneli ukuya kwi-inverter kunye nebhetri.
Izixhumi ezidibanisa iintambo kunye nezixhobo, ziqinisekisa ukuhanjiswa kwamandla okugudileyo.
Iifizi kunye nokutshintsha kokhuseleko, ukulawula kunye nokuqhawula amandla njengoko kufuneka.
Iingqwalasela ezingundoqo zoKhuseleko kwi-DC-Side Wiring
Amanyathelo okhuseleko afanelekileyo kwi-DC-side wiring yoqhagamshelo lubalulekile ukuthintela iingozi zombane kunye nokuqinisekisa ukusebenza kwexesha elide. Nazi izinto ezibalulekileyo ekufuneka uzikhumbule:
