Topic: Dual Honda 2000s versus AC Posted: 28 Jul 2015 at 11:11pm |
If anyone uses the dual Honda 2000s to power their 13.5 AC, here's my question: Should I expect to leave the "Eco throttle" off at all times when running my AC? Outside temp yesterday was around 100°. I ran the AC for a couple of hours with the Eco throttles off (i.e., at full throttle) and all was good. I then turned the Eco throttles on. I wasn't in the trailer at the time so checked on it after 20-30 minutes and saw that the surge protector had returned a low voltage error code. According to that info, I need to leave the Eco throttles off whenever I'm using the AC.
Does that sound right? I would expect to use full throttle when I first turn on the fan then compressor, but would have thought the Eco throttles would be able to respond to changes in demand after that. Thoughts appreciated .. TIA

Yes, you should leave the Eco throttles off when powering such a high startup draw item like an AC.

Odd, because with my Honda EU3000is I can leave Eco on with no problems starting up my 13.5K btu A/C on my Salem. It may even be a 15K, but I haven't pulled the cover yet to verify that. On my pod I could even run the A/C and microwave at the same time, with Eco on.
2800 watts continuous rating. Don't you get 3200 continuous with the 2000's paralleled? Once difference I can think of - the engine on the 3000 is oversized.

Doug, yes, supposedly 3200 continuous. I guess that, when the ac pulls a surge (if I'm using the right terminology), the generators just can't respond quickly enough to ramp up the power. If full-hrottle-only is required when using the ac .. well, disappointing to say the least.

We just got back from 5 days of dry camping in northern California with temps in the 90s. We have two Honda 2000s which were on eco mode during heat of the day. While the generators took a second to catch up they never faulted when the AC launched. With our 5th wheel they would fault frequently. Unfortunately I don't recall the size of the unit in that trailer.

We had a couple contractors doing some work today and talk turned to generators.
We have a 11k btu Dometic AC unit on our Pod and the contractor offered to check the draw on our Pods AC. 6.1 amps (732 watts) when the fan first starts up. When the AC compressor spools up it draws 22.5 amps (2700 watts) When running it draws 13.5 amps (1620 watts) |

Podamus, interesting. Wonder what's different between your Pod vs your 5th wheel? AC capacity? I ran ours for about 4-5 hours today (107°-109°) and, with eco mode off, never skipped a beat. Was afraid to try eco mode. You know anything about hard start capacitors? I'm thinking I'll give one of those a try. Thanks for the reply.

This is the best way to think it through. Equivalent numbers for mine (per my PI surge protector): 3 amps when fan starts .. 360 watts 17 amps when the compressor kicks on .. 2040 watts 13 amps when running .. 1560 watts Based on this, my dual Hondas should just lope when the compressor kicks on, even if in eco mode. As I mentioned in the post above, I'm getting real tempted to try a hard start capacitor. Thanks for the feedback.

I'm certainly no expert here, but it seems plausible to me that a paired set of generators create a situation where the immediate draw on the lead unit takes the initial hit and the 2nd unit immediately supplements. The EMS may be sensing this millisecond of a drop which is probably absent from the single 3000w unit.
Like I said, just a guess, I really have no idea what I'm talking about, but again, it seems plausible to me.
