Industry Standard Projects

AC distributor for photovoltaic projects

Pre-configured solution for the realisation of an AC distributor as backup between the inverter and the grid connection – the ideal, individually adaptable starting point for your project engineering.

The Industry Standard Project was developed to cater specifically for photovoltaic systems > 30 kVA in mains-parallel operation. The configuration is based on the AX compact enclosure 1281.000 with an Ri4Power 185 mm busbar system for power distribution and is tested in accordance with IEC 61439-1-2. The project also includes suitable fan-and-filter units and enclosure heaters for climate control, alongside compact circuit-breakers, NH fuse-switch disconnectors and overvoltage protection. Rated voltage 400 V, rated switchgear assembly current up to 630 A. 

You receive a complete Eplan project including documentation and a digital twin of the AC distributor. This Industry Sample can then be adapted quickly and conveniently to meet your particular needs. You save valuable time already during the engineering phase and can rely on a safe and proven system. Assembly is also accelerated significantly as the AX enclosure permits interior installation without further machining – no drilling, no punching, no cutting. The control system is assembled independently of the enclosure on separately fitted punched sections. This ensures unhindered access to all the installed equipment, as well as simple removal and reassembly of the control system.

Your benefits

  • Individual solutions can be deployed in record time on the basis of a pre-planned configuration
  • Proven system with optimally matched components
  • Fast and reliable delivery

Note​

  • For outdoor installation, protection against direct sunlight, rain and snow must be ensured.
  • The product list can simply be imported into your shopping cart in the online shop.
  • The Eplan project is available in the Eplan Cloud. To sign in, you require an Eplan ID linked to your company organisation.

Explained step by step

1 Project definition

The engineering and manufacturing of AC distributors for use in PV installations must permit variable dimensioning of the individual components (MCCB, NH, busbars) in acordance with the actual power output. The installation of metering and control devices must take into account the relevant specifications of the energy supply company.

2 Engineering

The Eplan project, the so-called Industry Sample, describes a fully functional AC distributor with compact air circuit-breaker, overvoltage protection and climate control. You receive a complete Eplan project including all CAD files, parts lists with the components used and energy-relevant diagrams.

3 Engineering – Wiring

All required design information is provided in full detail, including relevant specifications for the wiring ducts and support rails.

4 Integration of bundled manufacturer data

Via the EPLAN Data Portal library, all relevant article data is available for direct import into the Eplan project, simplifying the process of documentation.

5 Engineering produces a 3D model

The integrated Eplan solutions permit simple 3D designing of the power distribution system in EPLAN Pro Panel.

6 The digital twin of the AC distributor station is ready2go

The digital twin is a virtual model of the planned installation and permits simulations of the systems, interfaces and processes already during the early engineering phase. That reduces the number of necessary development loops, reveals any errors in good time and accelerates commissioning. The optimisation of all process steps offers enormous potential for time and cost savings.

7 Parts lists for direct 1:1 ordering

A list of Rittal components can simply be exported and added to the Rittal shopping cart – and all information relevant for subsequent ordering is immediately available to the purchasing office.

8 Significantly simplified maintenance with a digital twin

The possibility to create an AR model simplifies maintenance of the installed system. Service technicians, for example, can already simulate a planned site visit before they leave the office and can provide valuable tips to their local partners via a remote link.

9 Special requirements? No problem!

Modifications to the Eplan project to accommodate individual wishes and requirements can be implemented quickly and simply at any time. Components can be removed, added or replaced as necessary – the documentation is updated immediately and the digital twin is adapted accordingly.

10 Documentation at the press of a button

The transformer station project is realised in accordance with DIN EN 61439. When designing and building low-voltage switchgear, it is important that the documentation includes routine verification reports and a declaration of CE conformity.

11 Production integration and pre-assembly

Eplan data can be imported seamlessly into Rittal solutions to enable automated production – significant efficiency gains are guaranteed.

Upon request, the Rittal Application Center in Gera offers further value-adding services: Specialists are on hand to support the planning of your power distribution system, and we can also take care of partial pre-assembly of your low-voltage switchgear. The pre-assembled system components can then be delivered quickly and reliably – including customer-provided circuit-breakers from all well-known manufacturers.

12 The real twin as a 1:1 copy

Project realisation times can be shortened significantly with the aid of a Industry Standard Project. Along the entire chain from engineering to assembly and commissioning, major time savings achieve a distinct cost reduction.
