Generator Output

I would say that the 10A at 12V is going to take less watts than 10A at 240V

Based on that formula 1000W would potentially give 83A @ 12Vbut they have only included charging hardware capable of 10A @12V

It would have different outputs for power at 240V and at 12V I would think.

If my understanding of these things is wrong then I am sure that SOMEONE will point this out!

Muddy is correct.

Consider the 12V and 240V outputs as completely separate items except that the _total_ power drawn from both of them should not exceed 1000W at one time (that’s usually the case with gens. anyway?).

The components which provide the 12V output have been designed for a maximum load of 120W or 10A at 12V. Whereas the main 240V generator can provide 1000W or 4.1A at 240V however if you were to plug a _REALLY_ big battery charger into the 240V output it could provide 83A at 12V.

Does that answer your question? I'm not sure I really understood what it was :) Ask again if it doesn't.

Ahhh, Pajman Pete is an old Navy man from the days of DC ships and open frame switchgear!

Muddy and Mike are spot on. I'll speak mainly from the perspective of my EU10i Honda.
On the electrical drawings they show two entirely seperate windings within the alternator one for the DC and another into the Inverter for the AC.
These two circuits are totally seperate and have no eletrical bonding at all. And are therefore very different capacities.
The Honda drawing actually shows only a bridge rectifier between the windings and the DC outlet. Definitely unfiltered DC.

Put your left hand on the negative terminal of your battery and your right hand on the positive end of the battery. Now, tell me what you feel....nothing??? Good.

Now, put your left hand hand on the active pin of your 240v and your right hand on the neutral. (DO NOT ACTUALLY DO THIS...)

After you have recovered from the electric shock, heart attack, and third degree burns, you may realise it is not a good idea to compare thing that are unrelated.

What you have in the gennie is two seperate windings, one supplying the 12 volts DC at up to 8 Amps (100W), and the other supplying 240 Volts AC at up to (what you correctly calculated) 4.1 Amps.

The TOTAL load on the generator cannot be more than listed, ie 1000W (@240V), or 900W(@240V) + 100 W(@12V)

"Green Steam" is generated by renewable energy, Steam generated by the earths magnetic field & from other Green sources is green...

Thanks for your responses, I now understand.

Cheers

Just make sure you only use the "DC output" from these generators (Honda, Yamaha, Kipor, GMC etc) only to charge batteries - and only while you are monitoring them.

These outputs are toatlly unregulated - even when the battery is full, they will keep on pumping out full power into the battery and could boil the battery dry.

The outputs are rectified AC, not smooth DC, so they will damage many 12 volt appliances if you connected them to these "12 volt" outputs.
