Re: 5000w generator & inverters
Hi gentlemen
Im looking at generators and was told to look at a rackmount 5000w invertor as then you can use any generator..
Eu7000 honda is the model to look at for clean power ive been told but still learning from you gentlemen with experience
Trying to interpret what you are saying here, but your postulation is that if you buy a 5000w inverter unit, then you can use a POS generator, rather than getting an inverter-based generator like the Honda EU series?
If so, that's BS/Bollucks/whatever regional phrase you use for an emphatic no.
Firstly, in many situations, the problem with lower-grade generators is that they sound like a freight train. No external device will fix that. For me, this is a game over, terminal problem. Secondly, though an inverter may in some cases smooth out power issues from a poorly-regulated and/or undersized generator, the inverter itself may cause more harm than good.
Most inverters that I'm familiar with require a DC supply (hence the "inverter" function), and most upconvert a lower voltage like 12 or 24v DC for use from a vehicle electrical system or battery. I'm guessing that what you're referring to is a double-conversion UPS which contains a rectifier (AC->DC), a battery, and an inverter (DC->AC). High quality units may indeed make adequate-quality power, but a 6KVA double-conversion UPS is going to weigh a heck of a lot and be another giant box you need to deal with. Worse than that are the fact that many UPS devices do not actually produce a low-harmonic sine wave (many have so-called "stepped-sine" output), meaning the power coming out of the UPS may be worse than what's coming out of your generator.
Save yourself a giant headache and get the Honda EU7000 and try to run as much of your equipment at 240v as possible, which makes the generator's life a lot easier. Your clients will actually let you run the generator without making you put it 500' away from the event due to noise, it won't blow up your gear, and due to some particular aspects about how Honda does things with their inverter technology, you will likely be able to run more gear on the EU7000 than other generators claiming a similar size.
