Honda 2000 generator Fast Idle mode for Eco-ON extra Power

Ever think your generator is too small to handle the A/C load??

It is. The poor guy is screaming trying to run that. I wouldn't advise making a habit of it.

2 in parallel should do quite nicely. Be nice to your Honda!

The 2kW Honda is MAXIMUM rated or surge rated to 2kW and produces less for continuous loads. I am surprised that it can start a A/C of that size in ECO mode. The starting inrush is too great and the generator will sag and then overshoot.

You need to leave it ECO off while running the A/C. The surging is not good on the A/C or generator.

The entire purpose of spending $1000+ on this Inverter Generator is the Fuel Economy/quiet operation and I refuse to settle with Eco Off as a solution.

I will keep this thread updated on the attempts to modify eco idle speed or rejetting.

FYI I have the Whynter GREEN ARC-110WD AC with dual hoses that specs state 9.5amps maximum current

Simple. You need to add a TDR, Time Delay Relay, and a heavy electrical load (***)to your A/C.

The idea is that the relay delays providing power to the compressor for 2-3 seconds, initially providing a connection to the new "load". A/C switch "demands" cooling, the load comes on line, the genset revs up to speed, then the TDR switches the AC to the compressor.

*** 2 500W halogen bulbs.

An AC typically draws 3X the running load at compressor startup, maybe even 5X at times, high head pressure.

Spend 2000, and buy a second Eu2000i to run in Eco on position, and pair them. Your A/C will have no problems running both in eco off position.

Read the Honda information on their website. They recommend either a 3000 or a pair of 2000's for A/Cs over 9000 BTU. Start up load is too great for a single EU2000i.

You've under engineered your generator supply in amps, plain and simple.

You're running a motor at very heavy loads with just one, in very hot air that is far from being very dense. Since the air is not dense, it can not take on much fuel to burn with it in the engine, which is in essence a pump. Every heard of cold air intake? Or intercoolers?

Maximum current is once the unit is in full operation. It does not take into account start up current, which is easily double that, about 20 amps. Since your generator can make 1600 watts, 13.3 amps, max of 2000 watts, you're short on beans to start your A/C unit. You are also doing a diservice to one generator running it that hard all the time percentage of load wise, running that A/C day in and day out. Spend the money and pair a set of Eu2000i's to do it right.

You refused to do the load calculations, and you came up short. The rotor lock load at start up on your A/C exceeds the design limitations of your Eu2000i.

Thanks for the ideas

more likely the cold engine is running with a PARTIAL choke situation
making for a richer running engine with more fuel and slightly higher speed
NOT a high idle you can somehow permanently engage

My eu2000i runs at the same no-load speed, hot or cold, with eco on. The idle speed is 3,000 RPM, controlled by the computer. Eco off raises the idle speed to 4,300 vs. the maximum engine speed of 5,000 RPM.

On a 90 degree day parked in full sunlight, tha AC runs continuously with Eco Mode ON, but overnight it cycles off. Seems like a waste that I get Eco On all day, then have to run Eco Off during the night when it is barely utilized.

When i start it cold, then go to Eco Mode On, then RPM's are slightly higher than when it warms up and slows down even more. It IS Much Slower than Eco Off which wastes fuel overnight when the AC only needs to run a few minutes per hour. On this thread Please Refrain from suggesting the easy fix of Eco Off.
