Budgeting Temporary LED Wall Power for Installation and Commissioning

Quick answer

Budget temporary power as a separate quotation line from the permanent supply. For EA1000H9 and EA500H9, size the generator, distro and cabling on the maximum W/m² for the quoted indoor or outdoor configuration, not the average. Itemize hire duration, cabling, protection, testing and removal, and keep commissioning power visible until permanent supply is live.

Use maximum consumption for the quoted configuration

For temporary commissioning power, the sizing basis should follow the same rule as the permanent design: use the maximum W/m² figure for the exact quoted configuration, not the average. EA1000H9 outdoor models draw 170 to 240 W/m² average and 500 to 720 W/m² maximum; indoor models draw 100 to 192 W/m² average and 300 to 576 W/m² maximum. EA500H9 documents the same ranges. Cabinets run on AC 100-240 V, 50-60 Hz. For EA1000H9 and EA500H9, size the generator, distro and cabling on the maximum figures rather than the averages. Use the average and maximum comparison as a checking method, not as a substitute for the model-specific figures.

Keep indoor and outdoor lines separate. The documented maximum for outdoor configurations is 500 to 720 W/m², while indoor maximum is 300 to 576 W/m². A temporary generator selected from an indoor figure may not match an outdoor build, and vice versa. Our recommendation is to put the exact model, pitch, indoor or outdoor use, wall area and maximum W/m² on the temporary power brief before asking for a hire or distribution quote.

Separate temporary commissioning power from permanent supply

Temporary commissioning power is a distinct budget scope from the permanent supply. The permanent connection, switchgear and final cabling may not be live when the wall is first tested, so the temporary generator or distribution, its cabling, protection, earthing, testing and removal should appear as their own lines. Keep the display’s AC input scope separate from the temporary power scope so neither is hidden inside the other.

The quotation should also keep model pricing separate from electrical site work. EA1000H9 price depends on pixel pitch, screen size, cabinet quantity, control system, spare modules and freight, so every wall is quoted per project. Temporary power hire, fuel, cabling, testing and removal are separate cost drivers that should be requested line by line rather than assumed inside the cabinet price.

Temporary power quote lines and evidence to request

Temporary power lines to request

Ask for a temporary power quotation that shows both the sizing calculation and the commercial lines. The sizing calculation should name the exact model and configuration, state maximum W/m², and show how generator, distro and cabling capacity were derived. The commercial lines should show hire period, delivery, fuel or refuelling, cable route, protection, earthing, testing, removal and responsibility for each item. Our advice is to make the temporary power line independent from the permanent supply line so you can compare bids on the same basis.

A practical sequence before comparing temporary power quotes

Fix the exact display configuration first: model, pixel pitch, indoor or outdoor use, cabinet quantity and screen area. Request maximum and average W/m² for that configuration. For EA1000H9 and EA500H9, the maximum figure is the sizing input for generator, distro and cabling. Next, ask the electrical contractor to turn that input into a temporary power design with cable sizes, protection and testing. Defer quote comparison until the pre-purchase survey and temporary power brief are written.

Use a simple load check to keep the sizing basis visible. For an illustrative 20 m² outdoor wall using the upper documented maximum of 720 W/m², the display load would be 14,400 W (20 × 720). That is an arithmetic example for the display load only, using the top of the documented outdoor maximum range for EA1000H9 and EA500H9; it does not include other equipment or site allowances. Change the area or use the applicable maximum for the actual configuration.

Mistakes that make temporary power budgeting unreliable

One mistake is sizing the temporary generator, distro or cabling from average consumption. The supplied passages for EA1000H9 and EA500H9 say to size generator, distro and cabling on maximum rather than average. Another is letting the permanent supply quotation and the temporary commissioning power share one vague line, which hides what is included. Keep them separate.

A third mistake is omitting the temporary works around the power itself. Site protection, cable routes, barriers, earthing, testing and removal can change the temporary scope just as much as the generator size. Ask for those items as measured lines, and compare totals only when each bid uses the same model, configuration, hire duration and responsibility split.

Scenario checks for temporary commissioning power

Illustrative display load for a 20 m² outdoor wall at the upper documented maximum

Illustrative calculation: 20 × 720 = 14400 W. 20 m² is an illustrative wall area; 720 W/m² is the upper documented outdoor maximum for EA1000H9 and EA500H9; the result covers display load only and excludes other equipment or site allowances.

Buyer checklist

• Name the exact model, pitch, indoor or outdoor use, cabinet quantity and screen area before requesting a temporary power quote.
• Request maximum and average W/m² for the exact quoted configuration; use the maximum for generator, distro and cabling sizing.
• For EA1000H9 and EA500H9, confirm AC 100-240 V, 50-60 Hz on the quoted cabinets.
• Ask for separate temporary power lines for generator or distribution, cabling, protection, earthing, testing and removal.
• Keep permanent supply and temporary commissioning power as separate lines, and defer comparison until inclusions and exclusions are written.
• Request the site survey inputs before approving the temporary power budget.

Frequently asked questions

Which power figure should size a temporary generator for an EA1000H9 wall?

Use the maximum W/m² for the exact quoted configuration. EA1000H9 outdoor models draw 500 to 720 W/m² maximum and indoor models 300 to 576 W/m² maximum. The passage says to size the generator, distro and cabling on the maximum figures rather than the averages.

Does EA500H9 use the same temporary power sizing rule?

Yes. EA500H9 documents the same average and maximum ranges as EA1000H9: outdoor 170 to 240 W/m² average and 500 to 720 W/m² maximum; indoor 100 to 192 W/m² average and 300 to 576 W/m² maximum. Cabinets run on AC 100-240 V, 50-60 Hz, and the passage says to size generator, distro and cabling on maximum rather than average.

What temporary power lines should be itemized separately?

Our advice is to itemize the generator or temporary distribution, cabling, protection, earthing, testing and removal, plus hire duration, delivery, fuel or refuelling and responsibility for running the temporary supply. Keep those lines separate from the permanent supply scope.

Should average consumption size the temporary distribution?

No. For EA1000H9 and EA500H9, the supplied passages say to size the generator, distro and cabling on the maximum figures rather than the averages. Average figures remain separate reference data, but they are not the sizing basis for temporary power in those passages.

Why not treat temporary power as part of the permanent supply quote?

They are different scopes. Permanent supply covers the final connection, while temporary commissioning power is needed before permanent supply is live. Keeping them separate prevents a lump sum from hiding generator hire, cabling, testing or removal.

Can I get a fixed price for temporary LED wall power?

For EA1000H9, price depends on pixel pitch, screen size, cabinet quantity, control system, spare modules and freight, so every wall is quoted per project. Temporary power should likewise be requested as an itemized, project-specific quote rather than an assumed figure.
