ACDB is important part of SPV system to provide extra electrical protection to the system. ACDB incorporates AC breaker, SPD to ensure maximum protection to the sophisticated electronics equipment. Also ACDB have energy meter which help you to know how much energy generated from solar.
Enclosure ABS/ PC IP65
System Voltage 250V/ 500V/ 1000V
Number of input : 1 to 4
I/P +VE : Diode/ DC fuse
I/P –VE : Terminal Block
DC Disconn : DC MCB/ SPD
Cable Termination : Glands/ MC4
Both off Grid & On Grid Applications
The DC Distribution Box is used to provide flexibility for the operator of the solar power plant to disconnect and connect both the inward solar supply and battery terminals. Here an MCCB and a fuse of proper rating depending upon the capacity of the power plant and the battery bank are used. In the DCDB we have two sections one is the solar section and the other is the battery section. Solar Section/ Battery Section In solar section the incoming terminals from the MJB are fed to the input connectors and the conduction path takes place through the MCB and a HRC Fuse of proper rating selected as per the system capacity and the panel used in the power plant. The same is done for the incoming terminals from the battery bank. Monitoring section of DCDB the DCDB is provided with a digital Ampere Hour meter to observed the charging/ discharging currents of the battery i.e. Ah of the Battery. This meter is intended to work only on the AC external supply from the ACDB feeder.

ARRAY JUNCTION BOXES/ LT PANEL/ AC COMBINER BOX
ARRAY JUNCTION BOXES (AJB)
AJB collects DC power from PV strings which is directly or indirectly (through main junction box) transerred to power inverter. Power Inverter converts DC to AC which after metering is used for captive consumption or supplied to grid.
We specialize in Designing & EPC of LT Panels and ACDB with exclusive focus on high quality, optimum performance, and high tensile strength. Our panels are easy to mount and install.
AC Combiner Boxes
We have the expertise in manufacturing the AC combiner boxes with any number of input to single (one) output. Combiner Boxes take multiple source circuits and combine them in a single output. They are usually found between the modules and the inverter. VTECH Combiner Boxes are known for its clean and well thought- out design.
Available option include:
- Arc Fault Detection and Circuit Interruption
- Disconnect switches or contractor
- Surge arrester
BALANCE OF SYSTEM (BoS) FOR SOLAR PV
The Balance of system (Bos) encompasses all components of a photovoltaic system other than the photovoltaic panels. This includes and is not limited to a mounting system, combiner boxes, cable trays, cables/ wires, switches, enclosures, fuses, ground fault detectors, earthing and lighting arrestor. Excluding the solar panels and inverter this system makes up to roughly around 10-50% of total purchasing, installation and maintenance charges of the entire project.
Key highlights of BoS:
- Control cost
- Increase efficiency and increase greater solar PV adoption
- Modernize solar PV system
BOS APPLICATION SCOPE
BOS can be applied to all types of solar applications such as commercial, residential, agricultural, public facilities and solar parks
BOS Cost Reduction
According to the Near Term Balance of System Cost reduction Report some key cost reduction aspects to consider are:
- Bundled Bos system ( 1 supplier or manufacturer) vs. Gathered (several)
- Installation- Rooftop vs. Ground Mounted
- Electrical Components
- Inter connectivity / Equipment Compatibility
