The ACDB box is made of epoxy powder coated metal casting. Three feeders are provided in ACDB with MCB of Required capacity installed at each feeder in the ACDB. One Electronic Energy Meter, ISI make, is provided in ACDB to measure the consumption of power from SPV Power Plant. A separate dedicated feeder from conventional line to PCU as well as ACDB is also provided. A separate change over switch of required capacity is provided in the ACDB to isolate the existing connected load from the solar system & switch it over to the existing convention power (Mains), in case of emergency.Solar AC Distribution Boxes are installed immediately after the solar PV Grid-tie inverter.Protection in Load AC side in times of power failures is provided by ACDB. It can provide surge protection besides ensuring optimum protection to the sophisticated electronic equipment. In big solar PV power plants where a number of inverters are there ACDB is replaced and ACCB is used in its place. ACCB possesses one MCCB for each inverter and a master MCCB at the outgoing part. Virtually, all the features that are present on ACDB are very much there in ACCB’s as well. ACCBs generally find its use in grid connected/ grid tied / on-grid solar power plants. AJB or the Array Junction Box provides with an estimate of the amount of energy that can be used or withdrawn from that of the solar power plant. In case there is some fault on course of failure in DC side, DCDB/AJB is used for the purpose of protecting the system irrespective of it being Solar Panels or batteries. It is an integral and significant aspect of the SPV system for it is desirable that there is enough protection in DC side. In order to switch off the system while a fault occurs, there exists an Isolator/Breaker for immediately switching off the system. Also, there exists a meter that gives precise information regarding the current and voltage. Moreover, it has also got surge protection for saving the system from surges caused owing to fault and/or phenomena such as lightning and others. ACDB can be mounted on a wall as well as there is perfectly a provision for such arrangement. It’s operating temperature is between -10 to 55 degree Celsius. Its number of DC Inputs range between 2-16 while the number of DC Output is 1. The number of terminal blocks is 2 to 34. It’s Operating Condition is between -20 degree to 55 degree Celsius. It can furnish both short-circuit as well as surge protection depending on the requirement.
