  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

2x Arri M18's & 1x Honda 7000 ?

Anyone out there ever use the Honda 7000 to power TWO (2) Arri m18s? I'm assuming the generator has 2 separate 20amp sockets so it should handle the load...

- Bonus question since I'm waiting on my Cinematography-dot-com invite

Can I plug an Arri m90 directly into a Honda EB10000?
 
you my friend need to take a chill pill.

This is my first time reaching out for a tip/direction of meaning and "boom" get a bitter person to respond.

I know most folks here on the board are kind.

Hi Mat, Arris M18 are PFC and always start with 1200W not a very complicated load. You should be fine to run two on a 7000Honda. The M90 on a 10000 will probably fail. If you want to dig deep into this is an excellent read:

Edit: I don´t know why, Reduser don´t let me link to Screenlight & Grip they have a white paper for running Lights on generators.

Probably a lot you won´t find even when rtfm ;-) Have fun!

Cheers

Thank Ulf!

I'll probably end up rolling with the m18's & 7000 gen. Anything needing 220 power, I'm going to have the producer get all proper crew/gear involved and handle.

I saw the Screenlight & Grip article and that amount of technical info makes you realize when in doubt... let the expert g&e folks handle it!

Sorry Mat, I apologize, won't need a chill pill, you're comment was enough.

Ulf is right.

The M18 does 1800W/120VAC~15 amp's and the Honda 7000 delivers 2 x 20 amp's/120 VAC continuously (so no problem)
The M90 does 6000W/123VAC~49 amp's and the Honda 10000 delivers can deliver 50 amp's (6 kVA) at 120 VAC continuously with a High Capacity 120 / 240 VAC Twist Lock. (living on the edge).

Misha, Thank you sir.

Earlier I was really contemplating the m90, but with Ulf's link and your "living in the edge" advice, for sure will stick with the M18s unless I get full proper gear and crew for bigger lights.

This is when fitted with a 6K globe and I´d still give it some more headroom, even when the recent ballasts are PFC and high efficiency, just add some voltage loss in the supply cable and the amps will rise. With a 9K you´re definitely crossing the line. You might use two of those 7000 in parallel if you´re keen on the M90. Cheers!

The Honda's don't have a synchronizing circuit so I wouldn't use them in parallel.

May be not all of them. I do it all the time with the smaller ones. Love to be able to move them around without help and also adds some redundancy. Of course in this category you´re better served with a proper toe genny. YMMV.

It looks like that is more ment for redundancy then to double the output power. Since the honda 7000 can Output 120VAC 7000W max. (58.3A) and 5500W rated (45.8A) and the EU7000iS Parallel Kit, incl. 50A receptacle, only has an output of 50A.

I must admit that I understand Mat a lot better now, it's not the clearest FM i've read. It's almost like a sony camera menu interface ;)

The parallel kit actually doubles the power output also for the 7000 and is listed with 14000 Wattage. That boils down to a usable source for a M90. The fuses are 50Amps each Generator. You might also run those @240V which is easier for the M90 anyway. But as Mat already stated, better have an experienced G&E guy handle this stuff :-)

True, but they don't state that they can deliver 2*45,8A~90 Amps to 1 load. It's a bit like as with PSU's 4x30A vs. 1x120A. The 1x120A can deliver 120A to one load and you won't be sure that the 4x30A can do the same (the circuits deliver partially to eachother in parallel mode, because of "slight" fase, voltage and impandance differences).

P.s one of my back grounds is ABB inverter engineer.

So you´re way ahead of my knowledge :-) I thought it might just be the same tech as with my smaller units, they just add up and have no extra fuse for the total load. At 240V 50 Amp should be OK for the rated 11000Watts, not sure about a common load @120V, you may be right here. It is not well described, from the picture shown there are two leads going into the unit each from one genny and just one output socket (like with my smaller one). Unfortunately I´m not familiar with your USA plugs, we have other systems over here. Now I searched some places and it looks like the parallel kit is not easily available / work in progress for the 7000.Also Screenlight&Grip had made a custom one. Cheers!

According to their website, the ScreenLight and Grip paralleling box incorporates “proprietary paralleling control circuitry (that) uses the Pulse Width Modulation (PWM) of the generator's inverters to synchronize the phase angles of the two generators using an open-loop architecture. ‘ In effect it sets up a master/slave relationship, where one machine conforms to the voltage, frequency, and phase angle of the other, which means that the paralleling box puts out true single-phase power. ScreenLight & Grip also modifies the EU7000s to get sixty amps out of it’s inverters operating in series rather than the 50A accessible through the factory equipped power panel. As a result their paralleling box provides 60A per leg, single phase, which is enough to power a 12kw HMI.

In the ScreenLight & Grip system, you use a small 240-to-120V step-down transformer/distros to step down all or part of the 240V output of the paralleling box to a single 120V circuit (that is how they provide 100A for a single load.) Which size transformer/distro you use (100-,84-, or 60A) depends on how many 240V loads verses 120V loads you want to power. For a large 120V load, like a 10kw Fresnel, or a number of smaller 120V loads, you would use their 15kva transformer/distro to create a 100A/120V circuit accessed through a 100A Bates receptacle on the transformer/distro. The 100A Bates will supply a 10kw Fresnel directly or you can use standard 100A distro like lunch boxes to break that out to 20A branch circuits to power smaller lights. If you are, say powering an Arrimax M90 at 240V off the paralleling box, ScreenLight & Grip also has a Siamese that will allow you to supply the M90 while splitting the remaining 240V off to their smaller 7kva transformer/distro to create a 60A/120V circuit capable of powering smaller 120V loads like M18s at the same time as powering the M90.
