Electricity Power Feed to a NVR Panel (no Volt Relay) which will turn itself OFF if there is a power failure and invertor will not restart until power restore again. Also it is protect to single phase, over voltage and under voltage.
"Solar ACDB (Ac distribution board) is an important part of the SPV system for Solar power Plant.It combines the output 3 phase as well as single-phase AC power of inverter .AC-DB comes with the package of protection devices such as surge protection device (SPD), MCCB/fuse/isolator/MCB. Therefore protecting the electrical circuit from traveling surges, overload, and short circuits as well as human personnel from earth leakage fault which is fatal.
It has an Energy meter in which you can easily to read the generated power and current generation values like current, voltage, power factor.
The specifications and ratings of the ACDC Board vary according to load and inverter capacity.placed in the solar plant system into a single box called ACDB (AC Distribution Board)"
"Dc distribution board combines the dc power of solar PV modules strings into a single array. In Addition, a combination of all strings is made a pass through individual array dc fuses in shunt with DC SPD. Solar DCDB satisfies IEC-61439-1 and mandatory by MNRE and operates up to 1000Vdc.
The enclosure provides IP65 protection.
Complete electrical safety to avoid hazards.
Ferraz Mersen/Eaton DC Fuses to prevent overloads.
Reverse blocking diodes for reverse current flow protection.
User-friendly DC termination and decent cable management.
Easy cable plug-in and plug-out provision for cable connection.
Wall mounting design for easy installation and maintenance."
SOLAR ACDB DCDB is a part of a solar power plant. When sunlight is incident on the solar panel, the current and voltage are generated in the terminals of the solar cell. A grid-connected solar Photo Voltaic system consists of the following components. Solar Photo Voltaic array, Array combining box, DC Cabling, DCDB, Inverter, AC Cabling, and ACDB. In Other words, Solar ACDB is the AC Distribution board and Solar DCDB is DC Distribution Boards. Solar ACDB DCDB is LT panels that distribute power from Invertor to Load.
