Baahida loo qabo keydinta tamarta iyo ilaha la cusboonaysiin karo waxay ku boorinaysaa horumarinta alaabada sida gawaarida korontada, kuwa PV-ga beddela, iyo matoorrada korontada dabaysha. Alaabooyinkani waxay u baahan yihiin inverter-ka DC ilaa AC si loo gaaro nidaamka hawlgalka. Shaandheeyayaasha iyo capacitors-ka isku xirka DC waa qaybo muhiim u ah nidaamka korontada kuwaas oo bixiya taageerada baahida loo qabo kordhinta awoodda iyadoo la adeegsanayo danab sare iyo durdurro gariir.

Iyada oo ah shirkad tiknoolajiyad sare oo soo koraysa, CRE waxay leedahay koox cilmi-baaris iyo wax-soo-saar oo heer sare ah oo loogu talagalay qalabka korontada ku shaqeeya ee korontada ku shaqeeya, waxayna dhistay xarumo cilmi-baaris iyo injineernimo oo elektaroonig ah oo leh hay'ado cilmi-baaris oo caalami ah oo caan ah. Ilaa hadda, CRE waxay leedahay in ka badan 40 ikhtiraac iyo shatiyo qaab adeeg waxayna ka qayb qaadatay horumarinta 10 heer qaran iyo mid warshadeed, oo shahaado haysta ISO-9001, IATF16949, ISO14001/45001, iyo UL. Waxaan u heellannahay inaan horumarinno la-hawlgalayaal ganacsi oo badan si aan u horumarinno hal-abuurka korontada.

Badeecadaha caanka ah ee CRE:
① Kondensarka isku xirka DC
② Kaaliyaha shaandhada AC
③ Kaydinta tamarta / Kondenser garaaca wadnaha
④ nuugaha IGBT
⑤ Kondensarka dhawaaqa
⑥ Kaaliyaha biyaha qaboojiyey
