Ajb With String Monitoring

Hulasi offers enclosures and integrated sub systems like AJB with String Monitoring, PV string disconnector boxes, array / combiner junction boxes, main junction boxes, ACDB, DCDB for photovoltaic PV application in India.
AJB with String Monitoring basically collect DC power from [generally 4 to 16] PV strings. Collected power is then transferred either directly or through a main junction box [MJB] to power inverter. The Power inverter converts the DC power to AC which after metering is used for captive consuption [off grid application] or supplied [sold] to the grid.
AJB with String Monitoring are provided with one or more of the accessories mentioned below to improve their functionality.
--> Fuse / MCB for over load protection on each string
--> Fuse / MCB Over load protection on output side
--> Dis connector / isolator on the output side to isolate the AJB from the MJB / Inverter
--> Plug in [plug out] type PV string input connectors: these special connectors enable quick yet reliable connection and disconnection of the PV string from the array junction box. This is useful during maintance and site upgradation work.
--> Blocking DIODES for reverse current flow protection
--> Class II Surge Protection Devise for protection against electrical surges
--> Individual string performance monitoring device and device for data transfer to control room.
--> MC4 compatible string connectors
