Solar and industrial AC distribution boards (ACDB)
Accu-Panels Energy manufactures AC distribution boards (ACDB) in Ahmedabad, India for solar PV plants — rooftop, commercial and utility-scale — and for industrial AC distribution. An ACDB collects the AC output of one or more inverters, provides isolation, overcurrent and surge protection, metering or net-metering provision, and hands the power on to the 800 V LT panel, main LT board or grid interface. Boards are built to the project’s SLD and inverter details in IP52 indoor, IP65 MS or IP65/IP67 polycarbonate enclosures, as a CPRI-approved ACDB/DCDB manufacturer working to IS 8623, IEC 60529 and IEC 60947.

What is the solar Ac distribution board?
Solar ACDB (Ac distribution board) is an important part of the SPV system for Solar power Plant. Accu-panels is CPRI approved acdb dcdb manufacturer in India.
It combines the output 3 phase as well as single-phase AC power of inverter placed in the solar plant system into a single box called ACDB (AC Distribution Board).
What kind of ACDB is made?
We are making customized boards according to client’s specifications, such as indoor type (IP52), outdoor type floor standing, wall mounting, stand mounting according to the client requirement. Also, We provide IP67 Certificate for Polycarbonate box and IP65 certificate for MS box
What ARE THE FEATURES?
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.
What ABOUT STRUCTURE?
Accu Panels is making ACDB from 1.6mm / 2mm thick CRCA sheet steel in IP52 and IP65 enclosures as well as transparent IP65 polycarbonate enclosures for small rooftop plants up to 30kW.
We are one of the leading suppliers of the ACDB panel with customized solutions. This is not only user-friendly but also demands minimum maintenance.
Accu Panels is manufacturing ACDB according to International Electrical standards like IS 8623, IEC 60529 as well as IP65 protection levels.
All switches and the circuit breakers, connectors should conform to IEC60947, part I, II and III/ IS 60947 part I, II and III.
We are also making provision of metering and net metering to monitor the consumption and generation of power.
Fine ferrule, marking, dressing, and lugs of internal wiring.

AC distribution board applications
Rooftop solar plants (single-phase and three-phase string inverters), commercial and industrial solar with multiple inverters feeding a common bus, ground-mounted and MW-scale plants where the ACDB sits between inverter groups and the 800 V LT panel, hybrid plants with DG or grid interface through a DG–solar synchronising panel, and industrial AC sub-distribution where an inverter-fed or grid-fed AC supply has to be protected and metered before it reaches the loads.
Inputs required to specify an ACDB
- Inverter make, model, count and AC output rating per inverter (kW / kVA, voltage, phases)
- Single-line diagram of the AC side — inverter to ACDB to LT panel or grid
- Number of incoming (inverter) ways and outgoing feeders, with any future spare
- Protection requirement — MCB/MCCB ratings, SPD type, earth-leakage protection where specified
- Metering requirement — energy meter, net metering, CT class, monitoring or RS-485/Modbus output
- Site environment — indoor / outdoor, wall / floor / stand mounting, ambient, dust and humidity, cable entry
- Documentation needs — GA, wiring diagram, BOM, routine-test report, IP certificate
ACDB design considerations
- Enclosure suitability — IP52 CRCA for indoor rooms, IP65 CRCA for outdoor, IP65/IP67 polycarbonate for small rooftop plants; corrosion protection for coastal or industrial atmospheres
- Protection configuration — per-inverter incomer protection, common outgoing breaker, surge protection sized to the installation category, isolation for safe maintenance
- Busbar and terminations — rated for the combined inverter output with the project’s fault level [VERIFY: standard ACDB current range and kA]
- Metering and monitoring — position of meters and CTs, net-metering provision, communication to the plant SCADA where required
- Project documentation — GA and wiring drawings, ferruled and labelled wiring, and test records that match the delivered board
ACDB, DCDB and solar LT panel — how they fit together
On the DC side, string outputs are combined and protected in a DC distribution board (DCDB) or array junction box before reaching the inverter. On the AC side, the ACDB combines and protects the inverter outputs. For larger plants the ACDBs feed an 800 V LT panel that aggregates the whole plant before the transformer. The combined solar ACDB & DCDB page covers both sides of the inverter in one place.

Frequently asked questions
What does an AC distribution board do in a solar plant?
It combines the AC output of the inverters, provides isolation, overcurrent and surge protection, houses the energy or net meter, and delivers the protected supply to the LT panel or grid connection.
What information is needed for an ACDB quotation?
Inverter make, model and count, the AC-side SLD, protection and metering requirement, mounting and site conditions, and any documentation format the project needs.
Which enclosure should I choose — CRCA or polycarbonate?
Polycarbonate IP65/IP67 boxes suit small rooftop plants; CRCA IP52 (indoor) or IP65 (outdoor) boards suit larger and multi-inverter installations. The choice follows the plant size, mounting and environment.
Can the ACDB include net metering?
Yes. Provision for energy and net metering to monitor consumption and generation is built into the board where the project specifies it.
Can one ACDB serve several inverters?
Yes. Multi-incomer ACDBs combine several inverter outputs onto a common bus with individual incomer protection and a common outgoing feeder.
How can I share a solar project requirement?
Use the contact page to send inverter details, the SLD and site conditions. The solar team returns a technical proposal for discussion.
Share inverter, SLD and site details with Accu-Panels to discuss a suitable AC distribution board configuration.
