Muuqaalka

1. Nooca sanduuqa PP, faleebo resin qalalan;
2. Lawska naxaasta/boolal, meelaynta daboolka balaastikada ah ee dahaaran, rakibid fudud;
3. Awood weyn, cabbir yar;
4. Iska caabbinta danab sare, oo leh is-bogsiin;
5. Koronto badan oo gariiraysa, awood u adkaysi badan oo dv/dt ah.
Sida alaabada kale ee CRE, qalabka taxanaha ah wuxuu leeyahay shahaadada UL iyo 100% gubasho-in la tijaabiyay.

Codsiga

1. Si ballaaran ayaa loogu isticmaalaa wareegga DC-Link si loogu shaandheeyo kaydinta tamarta;
2. Waxay beddeli kartaa capacitors-ka elektrolytic-ga, waxqabad wanaagsan iyo cimri dheer.
3. Qalabka beddelida tamarta dabaysha (Pv inverter), qalabka beddelida tamarta dabaysha; Dhammaan noocyada qalabka beddelida soo noqnoqda iyo korontada beddela; Gawaarida korontada iyo kuwa isku-dhafka ah ee saafiga ah; SVG, aaladaha SVC iyo noocyada kale ee maaraynta tayada korontada.
