I'm looking into buying a new generator. Haven't decided between Honda and Yamaha yet. I'm looking for some insight to help make my decision. One of the models I'm looking at is the Yamaha ef2400ishc. This generator doesn't have the option to turn the eco-mode off. So my question is when using your generator to charge batteries through a G series inverter are you able to charge with the eco-mode on or do you need the generator running full speed To catch the load without losing the inverters lock on the generator.inverterreview.com

I know of no drawbacks to the Honda.I only know of 2 drawbacks to the Yamaha.1. Since it doesn't have a fuel pump, it is difficult or impossible to use an extended run fuel tank.2. If you have a Progressive Industries EMS unit, they have this disclaimer on their website (since you are looking at a different model, I don't know if this applies):Progressive Industries wrote:Yamaha Generator Please be advised the Yamaha Generator Model EF2000iS does not generate enough start-up current which causes the unit to overload. The generator then puts out non-true Sine Wave power. Progressive Industries units are designed to operate only on True Sine Wave power.For this reason, The Progressive Industries Warranty is hereby void if an EMS Unit is used in conjunction with a Yamaha Generator Model EF2000iS. Any damage sustained to the EMS unit are the sole responsibility of the customer.

Thanks for providing your views on both Generators. It helps me to pick best generator for me.

You haven't indicated just which size of genset you're considering but having previously owned 2 Honda EU2000i gensets I'd give the nod to the new Honda EU2200i which is priced the same as it's predecessor but weighs much less than a Yamaha EF2400isHC. Equip your trailer A/C with a MicroAir Easy Start Soft Starter Kit and your chances of successfully starting that A/C even at 90F and higher elevation are pretty good according to those who have done this mod, obviating the need for a larger, heavier genset.

Solar is a much better way to charge batteries particularly when in the absorption phase than a generator run for hours.

Owning two Yamaha I can confirm they don't do extended run in a factory config. The mod isn't hard or expensive, but still something to be done.I originally thought extended run was a big deal but found the internal tank lasts quite a while. In eco my gen will run all night long running tank heaters and the furnace. In the summer I use 2x 2kw for the rooftop unit normally from dinner until sunset, then it's cooled enough to not need the rooftop any longer.However I avoid camping on generator when the heat and humidity is oppressive.
