Interesting. I have a question regarding pairing of generators that ARE NOT identical in terms of running watts rating, as you are doing here. I seem to recall reading somewhere that your combined running wattage is going to be limited by the LOWEST rated unit in the pair, or of the three as you are doing.

In other words, the paired generators will share the load equally up to the point where the lowest rated unit hits its limit, and then stop. The higher rated unit(s) will not be able to take on an unequal load.

Can you comment on this? Does that appear to be the case with your units?

:):)

Have read plenty of posts that say all will contribute max wattage just fine. A 1000 and 3000 paralleled is not limited to 2000 watts.

The generators ramp up power as the voltage drops. At idle hondas are 125/127v and as more power is demanded the voltage drops until maximum output. I don't know the voltages exactly but consider for every 1v drop they add maybe 10% power. So as voltage approaches maybe 115 they are all running 100%.

OK, Hook up your 2 batteries in parallel, add the inverter and see how that works out which will help to determine your future upgrades and as such is a resonable plan.

Read up on how to load balance wire 2 batteries in parallel. This is the best way especially for 2 new batteries. Might as well do it right the first time.

Water pumps use very little power because they don't run very long. My coffee pot uses 1025W or 8.5A AC. That's 95A DC for say 15 minutes is about 24Ah, a significant draw. And with your small batteries the voltage may drop enough that the inverter shuts down. Especially in the morning after a nights battery usage. I have no experience with anything smaller than 2 GCs but others are better informed.

I'm not sure what this has to do with my post.

I have no way of measuring whether that's the case.

I do know that parallel sources (at least in DC) will contribute what they are capable of, independent of the others, whereas series connected source ARE limited by the smallest amperage unit. The triple parallel kit link shown above seems to say what I think.

Good question, but so far I can only speculate. Zia is in heaven camping in tall grass and hunting mice.

Thank you, and time2roll.

Not having any personal experience with parallel gen’s, I wasn’t sure. It was just something I remember reading that of course I can’t find now. Anyway, that would actually be ideal for me if you could connect a smaller and larger unit together, and have the full combined running wattage of each available for use. The vast majority of the time, the 900 watts available from my Yamaha is plenty. It’s only if I want to run the air conditioner though, that I need much more than that. I’d prefer to use a smaller, lighter unit most of the time, and then connect a ~2200 watt unit to it only when needed.

Tell Zia that Kahlua, Selina and Dixxie say hello :W

Parallel DC sources of the same voltge is NOT like parallel AC souces of the same voltage. AC voltage varies from + to - and connecting parallel souces MUST be coordinated so that the 2 frequencies and phase relationship are in sync. Few gens have this capability. Check your Yamaha and any other gen first before connecting in parallel.

The Honda website specifies which models AND SERIAL NUMBER RANGE can be paralleled. And there is a required procedure for connecting them in parallel, first shut down all gens, etc.

Then I still don't know why you made that post about the batteries.

“ Check your Yamaha and any other gen first before connecting in parallel.”

Yeah, I already know my Yamaha can’t be paralleled with anything, but the Honda 1000 can, which is also rated for 900 watts continuous. If I could verify that the full combined running wattage were available if it was paralleled with a Honda 2200, that would be the best setup for me.

Really, I’m just looking ahead to the day when the built-in Generac 3600LP goes casters up. I only occasionally use it, but it’s just a matter of time before some critical component fails, and I’ll find out that it either costs more than the generator is worth, or it’s made of unobtanium. It’s been out of production for several years now, and even the used parts are drying up.

I can't state with 100% certainty, but I am comfortable in saying the chances are very good it would work.

There are some youtube's on pairings of different sizes, but I didn't find one for that specific combination. I do seem to remember a 1000 with a 2000 some time back.

Asking Honda is an option, but even then I'm not sure their tech support would approve of it, as they don't approve of making your own parallel cables.

As often happens on these threads other topics are introduced. And that includes battery posts including at least one by you.
