Does anyone run this charger of a HONDA 1kva successfully or does it need the 2kva ?

Image Could Not Be Found


Trying to avoid lugging a 2kva around.

According to a couple of websites, the unit delivers a peak of 40amps at around 15.5v, or 620w. They also claim around 80% efficiency, implying a 240v input at around 780w, which would be a bit much as a continuous rating for the 1 kw genny. However, one would seriously doubt the unit would be running at 40w output continuously. Does this help? (or why use experience, when you can use theory?)

why would this a bit much for a 900w continuous rated genny?

Hi Andrew. As you say, the Honda EU10i has continuous rating of 900va, not 1000, and so 800 is 89% of the max continuous. A bigger margin seems sensible to me, and I am sure others have also indicated on this site that they'd prefer to see these little units running at perhaps 75% to be safe.
The saving grace is that the charger would not sit on 40A too long.

Thanks Chris. Whilst i recognise that the 40A drops off on these units (my xantrex 10A is hardly ever on the 10A setting), i would thought having 75% as a safe margin rather low....750w would be ok i would think. (we run the kawasaki models so i'm not sure of the honda variants).

John,
My experience with my own EU10i Honda tells me this would be an excellent combination.

The 40A Xantrex will keep a good solid load on the little Honda virtually eliminating the biggest killer of small generators, underloading.

I use a 30A 3-Stage charger on my own EU10i and it does it with ease, even with the eco throttle on and a couple of lights connected to the 240V side as well.

I run the Xantrex Truecharge 40 on the Yamaha EF1000is with no issue.

The Yamaha is a superior unit to the Honda EU10i
Yamaha has steel cylinder sleeve and Honda is aluminum and dont last
No fuel tap on the Honda EU10 is the pits and they leak fuel all the time.

Compare how much better theYamaha EF1000is here

Using both at work we will no longer buy Honda
