A Habré sukan yi rubutu game da sufurin lantarki. Kuma game da kekuna. Kuma game da AI. Cloud4Y ya yanke shawarar haɗa waɗannan batutuwa guda uku ta hanyar magana game da keken lantarki "mai wayo" wanda koyaushe yake kan layi. Za mu yi magana game da samfurin Greyp G6.
Domin ya kara muku sha'awa, mun raba labarin zuwa kashi biyu. Na farko an sadaukar da shi ga tsarin ƙirƙirar na'ura, dandamali da ka'idojin sadarwa. Na biyu shine ƙayyadaddun fasaha, bayanin kayan aiki da iyawar keke.

Lokacin ƙirƙirar dandamali don samfurin ƙirƙira, yawancin nuances suna buƙatar la'akari da su. Don haka, zabar dandalin gajimare don karbar bakuncin da gudanar da dukkan ayyukan da keken lantarki na zamani ke bukata, lamari ne mai matukar muhimmanci. Kamfanin ya zaɓi Amazon Web Services (AWS).

To wane irin keken lantarki kuka gama dashi? Keken dutsen Greyp G6 na lantarki yana sanye da baturin lithium-ion mai nauyin 36V, 700 Wh wanda ke amfani da ƙwayoyin LG.
