Its been a while since I operated an oscilloscope since my college electronics class, but what is the BEST (most versatile and SAFE) pure sine wave inverter for AC only studio flash strobe packs and monolights on the market today as of 2012 that anyone has had experience with? I plan on using mostly pack heads and sometimes monolights. There are times when the battery AC/DC strobes are not available and I may need to be on a location shoot with AC only strobes. I never liked gasoline powered AC generators much so thats NOT an option because they are heavy, bulky, noisy but mostly bad for the environment. For simplicity lets say I need 1000-1200W/s peak power, standard 90-130V AC/ 60Hz/ USA only AC currents bi-voltage optional for me ( I dont plan on travelling outside of the USA but I know a lot of photographers do so they may need a bi-voltage compatible inverter) , analog or digital lights . I ran across these inverters: Innovatronix, Alien Bees Vagabond II/ Mini Lithium and Dynalite XP-1100 pure sine inverters. **Please note Alien Bees does not guarantee compatibility with other brand strobes other than Alien Bees strobes with its inverter so you have to roll the dice when using a brand other than ABs as it may or may not work. Dynalite's inverter claims to work with all strobes and here is a compatibility chart from http://www.innovatronix.com/compatib.asp Strobes could be but not limited to Profoto, Speedotron, Elinchrom, Hensel, Dynalite and Bowens...ect. Whats the best pure sine wave inverter(s) TODAY as of 2012 that you have actually used on location that you recommend for most ANY major AC only strobe power pack and/or monolights. Thanks in advance for your responses.
