charging batteries with Honda2000
Is charging the batteries thru the converter faster in eco-mode or out of eco-mode with my honda genny?

If you want max speed you need to post what converter you are using.
Some are excellent, most are weak, a few are pathetic.
I have the pathetic brand. :B
So, I use a portable smart charger.sign man wrote:

Some are excellent, most are weak, a few are pathetic.- It makes no difference, the charge speed is the same in both modes.
Leave it in eco mode and save noise and fuel. pianotuna wrote:
interesting thought. gonna post a new topic.
If all you want is battery charging think about adding a solar system.
Eco mode makes no difference to the converter.
Do not attempt to charge to 100%. The generator would need to run all day long.- If all you want is battery charging think about adding a solar system.

Do not attempt to charge to 100%. The generator would need to run all day long. - We do a lot of boondocking, and after reading results on this forum, two mods are key:
1. Replace the OEM converter/charger with a better from Progressive Dynamics or similar. The charge wizard function allows you to force the charge into "boost mode" at 14.4v, and it will automatically kick back to 13.6v based on state of charge.
2. Upgrade the typical #6 wire between the converter and batteries. The location of the converter in our unit gave me about 30' of #6 wire, and I added a #2 in parallel on the hot side, and also increased the ground legs from the batteries and converter to the frame. This greatly reduces voltage drop and enables more the voltage output of the charger to make it to the batteries.
Before the mods, I would need to run the Eu2000 almost all day to get a good charge back in the batteries. Now I can kick the converter into boost mode and get the batteries back to almost 100% with 2-3 hrs of run time.
If you don't want to mod the RV, then go with the stand alone Iota charger as suggested above, and connect the charger directly to the batteries. You are accomplishing the same thing with a separate piece of equipment, ie 14.4v charging mode and good wire capacity from the charger to the batteries. - Shouldn't matter. The generator will run as fast as the load demands. In eco-mode, or running wide open, still producing 120V @ 60Hz. There's more current available at the higher speed, but if the charger doesn't require it, it's of no benefit.
If you're trying to do a fast charge to limit generator run time, you should consider getting a battery charger such as an Iota 55A model. It can do the 3 stage charging to prolong battery life, but it also comes with a plug to kick up the charging voltage to 14.2V, and will not reduce like a smart charger. Much faster, but you need to watch your batteries and make sure they are not boiling.
More detail can be found on page 3 of the Iota owner's manual:

- Hi sign man
I use my Honda Generator to charge batteries a lot as I am often boondocking out west somewhere.
I run the Gen on Eco mode exclusively to charge through the TT charging system. That is a much better charger then my backup 10 amp cheap charger. It takes 2-3 hours to top off the batteries when I use lots of electric during a day. Usually a charge will last 2-3 days of low use.
If I am using minimal electric (really nice weather in the summer) about an hour of charging is often enough every day or every other day.
I have never seen a reason NOT use the Eco Mode, plus it is quieter. Something appreciated by me and my neighbors.
