Thanks for all of that Guy. I own two of the Eu2000i myself and think that they are amazing little generators. Its good to read about how all of the various features on the whole line work from a gaffer.
Thanks! Dan Brockett |
Dear Guy,
Thank you for the very informative post. We have been using the EU2000i very successfully. It does work well with 1200 watt HMI's. But, just today, we were discussing getting another generator, so you post was very timely. |

http://www.screenlightandgrip.com/im...VR-Inv_Pkg.jpg The only way to avoid these problems with non-PFC electronic ballasts and conventional generators is to de-rate the generator by a factor of 3 to 1. For instance do not try to run more than a 1200W HMI on a 3500W generator of this type. While the generator does not need automatic voltage regulation and speed regulation when using electronic square wave HMI ballasts. Given the problems associated with the harmonic noise these ballasts generate, a more important feature these days is the quality of the generated power waveform and how well it interacts with your light sources. For this reason, I have compiled a comprehensive survey of the prevalent lighting and portable power generation equipment. Tested how well they work together and made the results available in our newsletter which you can access online at : http://www.screenlightandgrip.com/ht...enerators.html Quote:

For example, on a recent independent short shot on the Red, I used our modified Honda EU6500is Generator to power a lighting package that consisted of the 2.5kw, 1200, & 800 HMI Pars of our HD P&P Pkg, a couple of Kino Flo ParaBeam 400s, a couple of ParaBeam 200s, and a Flat Head 80. Given the light sensitivity of the Red Camera, this was all the light we needed to light a large night exterior. While our HD P&P Pkg. is very new (introduced Jan 09), the power generation issues it addresses have been vexing set electricians for years. In my newsletter article I attempt a detailed explanation of the electrical engineering principles behind these issues and how our HD P&P Pkg. resolves them. The article answers many of the questions being kicked around in this forum. |
