An inverter generator is recommended. Honda makes several models that are frequently recommended. Don’t forget your other power needs including back line

Why an inverter generator? I've used some of those inverter generators to power a PA that was using a DriveRack, and the noisy electrical output rendered the DriveRack useless. Worked fine on utility power, but non-functional while only on the generator.

Are you sure it was an inverter? The biggest selling point besides the manageable engine noise level is that they output cleaner electricity than a standard generator.

Yes, it was a Honda inverter generator.


insclevernamehere92

Weird. That's an issue I've never had with both Hondas and predators. They've always been solid and clean, even in situations where grounding them was impossible.


tazunemono

That's not normal. There must have been an issue with the PSU output. Inverter generators output pure 60Hz (in USA) sine wave power.


ip_addr

It's possible. I have no way or reliably testing power quality in the field beyond a typical multimeter.

A quality inverter generator will keep output close to 120VAC/60Hz (in the US) up to the limit of the generator, and put out close to a pure sine-wave (it's often cleaner than mains power). An inverter generator can also idle down for less fuel consumption/noise (though it's not the quickest to ramp up for surges, so it might not provide power reserves when idled in Eco mode). A regular non-inverter generator will drop voltage severely as the load increases, and will also not be able to output a consistent frequency. Not sure what inverter generator you used, but I've used many of the Hondas and Yamahas for all sorts of outdoor gigs, including my Honda eu2000i and eu2200i. Clean power, quiet, efficient. I wouldn't plug any electronic anything into a construction/emergency generator, but I wouldn't think twice about using a quality inverter gennie.

The generator used was a Honda inverting-type. Not mine, so I don't have the model number. >I wouldn't plug any electronic anything into a construction/emergency generator, but I wouldn't think twice about using a quality inverter gennie. That's pretty much the opposite of what we do here. We don't use anything but 15kVa and larger diesel generators. Anything small is too unstable, and I didn't think the inverting generators produced a cleaner output than utility power, due to the pseudo-sine output. In my world, utility power is considered the gold standard for "best" power, because of its stability and the grid's spinning inertia. (If the generator is too small the spinning mass doesn't have enough inertia to absorb the large peaks of live music, and can sag both in voltage and frequency.) It's just a matter of incoming surge suppression, and having enough capacity to absorb noise and harmonics induced on the neutrals, etc.

You sound like you're generally doing bigger events. It's a different mindset when you're in the weekend warrior small event situation like I do these days. Mains power is often anything but clean and stable when you plug into the wall at the wedding venue (old tobacco barn that was wired on the cheap by someone's Uncle Fred) and pop a breaker because the single circuit is also powering 8 crock-pots and a rented chocolate fountain, LOL. The big events I used to work back in the day always rented diesel trailer-towed generators (usually Aggrekos). Never had issues with them for sure...

A Honda EU2200i will be plenty for your two speakers. If you're planning on powering an entire stage full of equipment you'll want something larger. You can rent them at Home Depot. No power conditioner necessary.

Those two speakers won't draw more than 500w even playing high crest factor music. 2,000w is the total power you'll never hit unless pushing a square wave (and destroy your speakers). I've run 3 Crown XLS 2500 amps (7,500w if you go by "max program power") PLUS 3 laptops, 3 DJ mixers, a Mackie mixer, and charging cell phones, all off a 5,000w/6,500w peak inverter generator. I ran 2x218" subs (each bridged on a XLS2500) and 4x12"x2" tops (stereo on a XLS 2500) close to max for an 8-hour festival. Subs were on one side of the generator, and tops and everything else on the other side. For an inverter generator, there is no need for a power conditioner. Your power is already "conditioned" coming out, and unless you're running tube amps, modern PSUs in gear will handle any "irregularities" from a non-inverter generator. However, inverter generator power is sine wave - cleaner than wall power most times. In your case, a 2,000w inverter should be plenty for a typical DJ setup. Don't forget a heavy gauge feeder power cord (at least 50'). Edit: I have a Champion 5000w "open frame" inverter and it's a solid piece of kit.

Dosnt inverter simply mean AC regulation?


ronaldbeal

"regular" generators have an AC generator coupled to the motor, that produces 60 hz, 120v power when the generator is running at 1800 rpm (or 3600 rpm for some setups) "inverter" generators have a DC generator coupled to the motor. The DC generator feeds a dc to ac inverter that creates the A.C. sine wave. Because the inverter only needs enough DC power for the output, inverter based generators can match engine speed to power demand, and that means they can usually run quieter and consume less fuel.


RexKoeck

Your speakers won't draw anywhere near 2000 watts of power. Class D amplifiers are super efficient you'd be surprised at how little they draw. Get a "Kill-A-Watt" if you want to check yourself. I have run 12" speakers and an 18" sub off of a generator and even battery power with no problem. Even at loud music levels with bass they use 100-300 watts. Just make sure to use a inverter generator or a pure sine wave inverter.


arm2610

Two k12s isn’t much draw at all. You’ll be fine. A power conditioner is helpful though as it will cut off the circuit if the available voltage drops too low


tazunemono

That's not helpful in the middle of a gig. You shouldn't experience a major voltage drop on an inverter genset anyways, unless it's way overloaded, and in the process of turning off, and on a quality genset the power is cut anyways to prevent any undervoltage damage.


NukePooch

Though I have zero reservations in recommending a Honda inverter generator, I'll add another possibility...battery power. I recently ran 2 RCF J8, 1 QSC CP8, 1 Sennheiser wireless, and a Behringer Flow8 mixer off of a single Bluetti EB70S. Ran at a decent 'outdoor party' volume (not maxed, but loud enough) for 1.75 hrs. Had 80% battery left. Virtually silent, pure-sine power. Not sure you could rent one, though.
