battery charging

The ELEVATION that you are running your EU2000i generator at will also affect it's load handling ability. You lose power with elevation, ask any airplane pilot.

I think now the charger doesn't know how much of the R it sees is from the wire and how much is from the battery. We do know that as battery R climbs, at some point amps taper, and when they do, input power required by the charger drops.

So IMO (for now :) ) if the wiring R is so much that amps are lower, then the power input to the charger would be less.

Testing for that, be sure that the input 120 voltage remains near 120 so the lower amps you see is not in any portion from lower voltage input. Also the batteries must be at low enough SOC and big enough in AH to accept the charger's max amps if they can get there.

If the wiring is long and thin so R is high, is the 80 amper working just as hard but not getting so many amps through, as if it were on short, fat wires and doing all 80 amps?

Good question. If I get the chance I might see just how much voltage drop the wire is actually responsible and at least figure out how much "power" I'm wasting there. I don't know either.

Not too misleading. Eu2000 is still 13A*120V output. 1600W(VA). So, unless they have 90A converter...

This says the 9280 wants 1300w input. We know it has a PF of 0.7, so the VA required = 1857 (it also wants a 20a circuit)

The Honda 2000 is rated at 1600VA continuous. Some folks say they can run their 9280s with a Honda 2000. I don't know how, but I know my Honda 3000 can do a bit better than rated.

I have a couple of the early champion inverters that barely handle 1600 VA in perfect conditions. Despite being underpowered on paper, I've always been able to run my 9280 with the gen, mostly because heartland doesn't know what they're doing. undersized wit run probably 20 feet between batts and converter and I only have approx a 210 ah battery bank. Batteries rarely accept more than mid 40's amp wise. One of many things I need to fix now that I can keep trailer at house.

When charging (2) 12volt rv batteries through the on board converter/charger, would two honda eu2000's work any better than just using one genny to charge?

Dang reset bug
NO: About the biggest converter made is 80 amps, Mine runs on a EU-2000i at full output (in fact it needs only 1,000 watts so power is left over.. Inverters I've seen 125 amp.. Still within a EU-2000i.

Very misleading. You use VA input required from the generator. BTW there are 90, 100, and 120a converters. Perhaps others.

No. Your charger is (likely) within the capacity of a single Honda, and after you've charged them to 85-90% even that one Honda becomes too much. For finishing stages you need solar or shore power.
