Portable generation
Portable power for outdoor projection: load and continuity
For outdoor projection, review both the power supply and image visibility under the expected ambient light. Generator capacity and the projector brightness needed for the image require different data.
Plan the whole system
Request the projector’s electrical input in the planned brightness mode, its voltage and frequency requirements, and its manual’s shutdown instructions. Epson documents modes that change power consumption and brightness for specific models; use consumption data for the mode the image requires.
- Include player, computer, converters, network and sound.
- Compare confirmed venue power or a compatible battery when the program cannot tolerate interruptions.
What to send for a power review
- Model, lens and operating mode; schedule including tests and shutdown.
- Each device’s load, restart tolerance and appropriate environmental protection.
Planned location and operation
Run a fuel-powered generator outdoors, away from openings, with exhaust directed away from buildings and people. An enclosed tent, garage or equipment room is unsuitable, even with ventilation. An automatic carbon monoxide (CO) shutoff does not permit indoor use.
In the United States, CPSC recommends at least 20 ft (about 6.1 m) from buildings. Also check the manual, air intakes, audience areas and venue rules before choosing a location. In Argentina, check the local equipment version and the jurisdiction’s and venue’s requirements.
Plan for a dry surface and rain protection as specified in the manual, without enclosing the exhaust. Shut down and let the generator cool before refueling. If the site cannot support these conditions or the required breaks, compare another power source.
Never feed building wiring through a wall outlet. If the project requires a transfer system, request an authorized system and review by qualified personnel. That review must cover protection, grounding, neutral configuration and distribution; do not use improvised adapters.
Frequently asked questions
Can lumens be converted to watts?
No. Obtain electrical input for the chosen model and mode.
Can I cut power when the video ends?
Follow the projector manual’s shutdown conditions; do not assume a universal waiting period.
What should I check when adding a UPS?
Check compatibility, power, runtime and transfer behavior with the planned loads. Arrange a system test to assess whether it can sustain projection and support the shutdown required by the manual.
