October 2010: Hulasi offers enclosures and integrated sub systems like
PV string disconnector boxes,
array / combiner junction boxes, main junction boxes, 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
consuption [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
maintance and site upgradation work.
-->
Blocking DIODES for reverse current flow protection
-->
Class II Surge Protection Devise for protection against electrical
surges
--> Individual

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. Hanut India is 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.
Hanut India can fully customize the PV generator junction boxes to meet
customers' special requirements.
Array junction boxes by Hanut India
are installed in several MW size solar PV power plants and also in
telecom tower based solar PV projects.
Direct & Indirect customers
include Lanco Solar, Kirloskar Limited, Moser Baer,ACME...
