Solar BOS

Salzer was established in 1985 with German Colloboration for

Rotary switches to bring to the Indian Industry world class

technology in Low voltage switchgear Products, coupled with

dependability and excellence in service, to the delight of all end

users.

We seek to understand the requirements of our clients and provide

them the perfect electrical solution. All our ongoing developmental

activities for innovative and value-added products are driven by this

sense of responsibility.

With this in mind Salzer now introduces SOLAR BOS (balance of

System) to the market.

Introduction

Solar Array Junction BoxAn Array Junc�on Box (AJB), is used to connect the photovoltaic strings in parallel. The combined DC power

is fed to the photovoltaic inverter. It includes photovoltaic string protec�on, over voltage protec�on and a DC

output switch isolator. The AJB can be customized for different configura�ons, based on the number of

strings of solar panel modules used in the layout.

Solar main Junction BoxA Main Junc�on Box (MJB) is used to combine the mul�ple outputs from mul�ple numbers of Array Junc�on

Boxes in the Power Plant and form a single output that can be connected directly to the DC Distribu�on Box

(DCDB) or Power Condi�oning Unit. (Solar Inverter). The main important features of the Main Junc�on Box are to provide a single output.

Product Feature (DCDB)AJB made from imported refined Poly carbonate material. The box provides IP 65 level protec�on from

dust and water.

Fuses/MCB for over load protec�on on each string.

PV MC4 connectors are plug in [plug out] type: These special connectors enable quick yet reliable

connec�on and disconnec�on of the PV string from the array junc�on box. This is useful during maintains

and site upgrada�on work.

DIODES are used to block the reverse flow of current.

Surge Protec�on Devise (type-II) for protec�on against Electrical & Lightning surges.

AC distribution boxAC junc�on box or distribu�on Box (also known as panelboard, breaker panel, or electric panel) is a

component of an electricity supply system that divides an electrical power feed into subsidiary circuits, While

providinga protec�ve fuse or circuit breaker for each circuit. In the AC distribu�on box receive the power

from the solar PCU & directs into AC applica�on through distribu�on panels.
