Small Engine Problems? Ask an Engine Mechanic for Answers ASAP
Not sure what AVR is, please expand with a few more words. Also, still hands down with an $800 price difference at the 6500 watt level?
Also, it looks like Yamaha has a "boost" feature (at least on the 3000 wat model) which allows drawing from the starting battery to handle inrush current for up to 10 seconds. If Honda doesn't have this, I'll bet a paycheck they will on the next model year.
I have a Honda Eu3000isa that will trip when starting a 12000 BTUH air conditioner in the RV unless I start the fan first (vent mode) and then set the T-stat to allow the compressor to start.
Just thought the boost mode from the battery was a good idea.
Also, please confirm that Yamaha is not "labeling" Honda EU's.
I understand a 2 pole generator needs to run at 3600 rpm for 60 htz output. But the Yamaha also has throttle control for light load, variable engine speed....ie pulse width modulation (PWM) output on the inverter from a dc (current source inverter).
Don't buy the clean power arguement of Honda over Yamaha. They both have inverter pwm technology right?
You've presented the sales "puffery" ....but in all honesty, no convincing technical persuassion. I own a Honda Eu3000isa, but I'm considering upgradeing to a 5000 watt plus/240 volt generator to avoid nuisance trips when starting an RV air conditioner and also provide 240 volt for the home deep well pump. The Honda is SUPER quiet (49-55 db), but has no 240 volt output for home stand-by.
Clean power and PWM from an inverter to make the "perfect" sine wave is OLD news to me. That sales hype has been around since the '80's on VFD drives. AVR....show me any generator on the market that doesn't regulate field current with load. Your're talking to me if you mention time constants for recovery and overshoot for 100% step load changes (comparisons). THD after a transient is boring.
Tell me something specific between the Honda and Yamaha "smart throttle" technology and why Honda is worth $800 more without "boost technolgy" from the dc batteries for motor starting.
I repect your Ford/Chevy arguement and have used it myself many times.
GM went bankrupt, and Ford still has those "stupid" idiot gauge scales.....haha.
$800 more for the F-150?
I was just fishing for some serious Honda/Yamaha inverter output generator technolgy differences.
I've accepted your input....
I have an MSEE.
Hope you still resolve this in you mind and reply.
No, you did not upset me.
The written word can be ambiguous.....as anyone who's read blogs knows :) :)
You have been nothing but professional/cortious.
Yes, I was surprised also to see Yamaha coming into the market, and the "boost" technolgy I thought was inovative.
You have a good point regarding "discounted" Honda's. I need to search more.
Thank you, XXXXX XXXXX stand by my bet that Honda will be coming out with a similar "boost" feature with all their "super quiet" model for RV's. Starting an AC unit is the defining capability.
Actually, I have been a Honda small engine fan decades. Since the Honda Mini-Trail Z-50. I was just playing the Devil's advocat after seeing the Yamaha Generators with the innovative "boost" technolgy off the starting battery. I guess I'm P.O.'d that I didn't think of it and hold the patent.
OK, for Sept 2009, you've won the debate.
But, is Yamaha going to take market share with this boost technology? I think they will if it is worth a darn and they have a tightly worded list of claims in the patent.
I sent a bonus for your efforts. Confirm to me you received it and we can close this dialog. Thanks so much for the input/thoughts!
