"DC Coupling Ka Baara Kɛ tuma bɛɛ".
DC coupling bɛ se ka dɔ bɔ fɛn caman tigɛli bɔnɛw la PV-ka-batiri sira kan, nka baarakɛcogo bɛɛ lajɛlen fana bɛ bɔ baarakɛcogo la, sumani dancɛ la, ani dɛmɛnanw tacogo la. Yɛlɛma sira surun tɛ baara kɛ tuma bɛɛ ka kɛ poroze nafa bonya ye.
"Components dɔgɔyali kɔrɔ ye tuma bɛɛ ko poroze musaka ka dɔgɔ".
Inverter tila-tila bɛ se ka dɔ bɔ minɛnw ka ɲɔgɔn falen-falen na, nka poroze musaka bɛɛ lajɛlen musakaw fana bɛ DC/DC jiginni, lakanani, kɔlɔsili, baarakɛcogo, ani fɛn caman sɛmɛntiya nataw musakaw fana sen don. Minɛnw jate fɔlɔ dɔgɔyali bɛ se ka baarakɛcogo walima u bonya dantigɛli gɛlɛnw lawuli kɔfɛ.
"AC Coupling ye Tile porozɛw dɔrɔn de kama minnu bɛ yen".
AC coupling ka ca retrofits la, nka a bɛ se ka baara kɛ fana porozɛ kuraw la minnu bɛ rezo charge flexible, dispatch yɛrɛmahɔrɔnyalen, walima modular expansion wajibiya. Porozɛ taabolo ye fɛn dɔ ye caman cɛma-a tɛ fɛn dilanni dɔrɔn dantigɛ.
O sangaɲɔgɔnma b’a jira ko fɛn dilanni fila si man kan ka sugandi ka bɔ nafa kelen na.
AC coupling bɛ caman di yɛrɛmahɔrɔnya ni modularité caman ma. DC coupling bɛ se ka PV-ka-batiri sira surunya ani ka baara kɛ ka ɲɛ ni fanga tigɛlen ye walima ni ɲɔgɔn cɛ jɛɲɔgɔnya seko ye.
