ACDB is an important part of SPV system. It gives extra protection to the system in case of failures on load side. ACDB is made up of breaker, isolators, voltage and current monitoring etc. To ensure maximum protection to the sophisticated electronic equipment, it has provision for surge protection in the box along with fuses. Also ACDB have energy meter which help you to know how much energy you are using or withdrawing from the solar energy.
AC Distributed Panel for high DC/AC current Application. These panel are customized as per the design of the solar plant.
IN ACDB (LT Panels) we do have an expertise to design and provide for residential rooftop project 230V to Industrial rooftop and sheds 415V AC distribution panels. On request we can deliver high voltage 600V-800V AC Distribution panels which generally needed for Ground mounted projects.
DCDB is used where DC current rating is very high and incoming and outgoing of the DC current is need to be fused. High Quality DC fuses are used for incoming and outgoing through Buss bar. Surge Protection is provided in this panel in order to absorb excess surges in the system.
DCDB used to protect the system if there is any fault during failure on DC side. A very crucial part of SPV system as there should be adequate protection on DC side. The DCDB incorporates isolator/Breaker to switch off the system during fault, there is a meter which tells you exact PV array voltage and current you are getting. It also has surge protection to save your system from any surges occurred due to fault or other phenomenon.
Array Junction Boxes [AJB], is referred to as solar PV generator junction boxes and combiner boxes. It collects DC power from PV strings (generally 4 to 16). 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 in off grid application or supplied to the grid in On Grid solution.
Array Junction Boxes are provided with following accessories for improvement of 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.
