What is really cool about the AlienBees is that they consume very little energy making them great for battery work.They don't use transformers to elevate the current to store in the capacitors, but instead use multiplier circuits designed by Paul Buff.

I can shoot an 800 with 150watt inverter on a 15Amp batt for a couple hours heavy shooting. What is really cool about this outfit is that it is ultramobile. Suited for very fast work.

Yes, generators are great when you won't be jumping all around the place, typical in catalog shoots.
The big BUT about generators is when they are not yours or when they are well worked out. When they start choking and giving trouble they are a PITA.

Sorry, can't agree that they are the best solution. Good, but not the best. The inverter I plan to upgrade to is 3000W pure sinewave, 6000W for 5 seconds peaks, no mechanical parts so more reliable, silent, no pollution (making it suitable for indoor locations), and no fuelling hassle. I already have the 1800W version but I want even more.

Hi Graham,

Can you post a link to the 3000W & 6000W pure sine wave inverter with no mechanical parts, fumes or fuel needed???

Here's a link to a 3000W Max & 2800W continuous load of pure sine wave energy @ nearly 1/2 the price of the Honda version with same features [a href=\"http://www.amazon.com/Kipor-3000-Generator-Inverter-65788/dp/B000RUOY2S/ref=pd_bbs_sr_1?ie=UTF8&s=hi&qid=1213317564&sr=8-1]http://www.amazon.com/Kipor-3000-Generator...13317564&sr=8-1[/url]

Oh and link to user reviews of the Kipor 3000 Inverter http://www.amazon.com/review/product/B000R...howViewpoints=1

Thanks

I have been thinking about whether to get commercially involved with the company that makes these, specifically for the photography market, so can't say too much right now. I've been pretty impressed with the 1800W unit, and used that to power my Profoto Pro 6 1200 and 2400 generators and laptop on location for the past 2 years.

Here is the 3000W unit:



You need to add a sealed 12V battery and charger of your choice, depending on the capacity and weight you want. These are cheap and easy to find. I have a 75Ah battery which has never run down on a shoot, but YMMV. I have a 40 Ah backup.

Batteries are ok for a small shoot and I've tried most of them, but none of them lived up to my expectations or produced the amount of power we actually needed.
[a href=\"index.php?act=findpost&pid=201248\"][{POST_SNAPBACK}][/a]

I can only suggest that the units you were supplied with were not up to the job, or the power rating was overly optimistic. It's a matter of picking the right unit rather than blaming the technology.

If only I were in NY we could settle this the fun way (on a test shot)

I like that it's green friendly, no fumes etc. making it great indoors as well.

What's the weight & price of the 3000W unit by itself and where can I buy one? is there a link?

Cheers

I am just positive that the day will come where I have to bid a job based on the carbon footprint the project produces and I'll probably be required to wear hemp shoes.

Regardless of the 10 million green logos that have popped up all over the airwaves, magazines, computers and billboards, I can promise you, photography for advertising and commerce is not a save the planet business.

P.S.

You have to fill the batteries up with something.

in Australia, how much of our electricity is produced using coal, hydro, wind and tidal?

According to figures available to EnergyAustralia, about 85% of electricity is generated from coal, about 8% of electricity is generated from hydro sources and less than 3% of electricity is generated from wind and tidal sources.

You'll want to look closer to home, mate. http://www.latronics.com . Jury rig it to a Deep Cycle Sealed Lead Acid battery and an appropriate charger for the battery.

Haven't used these but they look like they would also do the job according to the specs.

Just noticed that their 3000W unit (and many others) use 24V or 48V inputs. Not so convenient.
Also, RRP for the 3000W unit is AUD 3190 (1969).

You go up to 3000VAC and over, you'll be looking at 24V batteries, at least, with any brand including that unit of yours.

No, it's a 12V unit. Why are you making things up you can't possibly know?

Quote
Yeah, try shipping 30 kilos from Europe to Australia and you will find out what it costs in a hurry. That AUD3190 RRP is not gonna look so bad after all.

Wrong again. Still around AUD 500 cheaper even with air freight and GST included. I really don't care which one he buys but please stick to the facts. (Buying locally does have the advantage of being easier to service if it fails).

Check the specs on your 3000VAC unit and see whether it runs off a 12VDC battery. Don't get all so cocksure and simple-minded about something beyond you.

I don't know why you insist on making a fool of yourself. Are you drunk? It's a 12V unit, just accept it. If this is what you do for a living then perhaps it's time to look for a new job.

I've been thinking about this for running a monitor on location. And I'm amazed at the times your quoting. I bought some bits as a test. With a 10Ah SLA batt and a 150W inverter I only got 70 minutes. Granted its just a cheap inverter that might be inefficient but a 40ah batt isn't going to run a screen all day.

This is cool.

I've seen arguments over the 1dsMarkXXIV vs. the Phase 45 double plus, arguments over used profoto packs, arguments over Hasselblad Focus software, but this is a first, a real heated argument over a 12volt inverter.

Next we're going to have comparisions over which mouse pad is better.

James I highly doubt that because everyone know that an A3 gridded cut matt is the best mouse pad    I am amazed by the times quoted for a 40ah battery. I'd so love to leave my 1k honda at home more often.

After reading this thread I understand why registration on the forums is closed.

It's to protect the public.

BTW: What's the deal with all this euro equipment in 1950's colors?

Well, I guess that orange thing will go well with that blue Sinar camera.
