| | Enclosures And Integrated Sub Systems We offers enclosures and integrated sub systems like PV array / combiner junction boxes, Battery Protection Panel, ACDB, DCDB for photovoltaic PV application in India.
Array Junction Boxes [AJB], also referred to as PV generator junction boxes and combiner boxes, 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 consumption [off grid application] or supplied [sold] to the grid.
Array Junction Boxes 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 maintenance and site up gradation 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.
This is useful in case of large PV installations. This enables easy identification of PV modules that are performing at below optimal level. after identification such PV panels / modules can be repaired or replaced.
MC4 compatible string connectors
Because Array Junction Boxes are installed in outdoor environment near the PV modules they are normally required to be made from a material that is rugged, fire resistant, electrically insulated and UV resistant.
Poly carbonate is one such material. We are supplying Array Junction Boxes made from imported refined Poly carbonate material. The box provides IP 65 level protection from dust and water. It is Class II electrical enclosure & is UL 94 certified.
We can fully customize the PV generator junction boxes to meet customers' special requirements.
Array junction boxes by Deepa Industries are installed in several MW size solar PV power plants and also in telecom tower based solar PV projects. |
