Invertors v Battery (1 Viewer)

[manda3000gt]

With these Invertors installed (8000w each) how long will my 110ah leisure battery last running the wife's hairdryer ??

 

[Jaws]

I know the question is tongue in cheek but actually the answer is....



It depends on what the hair dryer is rated at !

The inverters will draw very little current on their own, and being so big are probably pretty efficient too

Just showed the wife,she wants the same, I laughed out loud

It's on board the new Everton FC football coach that we valeted on Tuesday, we have the new Liverpool FC one to do before the end of the month with even more equipment on board

What can they possibly have to need 32kWh of power.....or do they run the grounds floodlighting off the coach.

Sorry to jump the thread but I have a split charge system/80a solar and 2x 110a LB.I have a 600 inverter with which I intend charging off grid a laptop and a 36v/10ah elec bike battery (preferably plugged in while driving van) Will it be possible as I go on aires etc?

Yes you can.

We had a 75w solar panel on previous PVC and 2 x 95a batteries and use to do as you are planning, I made a cradle out of a motorhome stacking cup holder which I fastened up under the dash on the passenger side into which the inverter was fitted and strapped to keep it in place, but so that it could be removed and used elsewhere if necessary then on the cab floor underneath it I fastened some straps which held the battery being charged in place so it could be done on the move safely, the 12v ciggy lead from the inverter was then simply plugged into the 180w outlet on the dash.

Oh, forgot to say, we don't do campsites, just aires or wild camp for 7 weeks twice a year!

So you think it should be successful to charge Leccy bike battery?

36v !?!?! From 12v !?!?!
Explain, some techno wizard please !!
As we are considering lucky bikes.

The bikes battery charger is plugged into a 13 Amp mains socket in the vehicle in the same way you would at home. The mains sockets within the vehicle are driven by the on board inverter/s which convert DC power to AC power.

Yes, we've done it without a problem.

36v is just the size of the battery itself, it doesn't mean it is re-charged at 36v.

That explains it then, it's the hair drying requirements for all the footballers along with the ceramic tongs...

But the size of a battery is measured in A/Hours.
36 volts means 3 times a 12 volt battery surely ( yes I know your name is Mel)

Correct, but you need to be carefull with calculations based on amps when the voltage is different, if you worked in watts/hour as in ah x volts it could be less confusing.

Yes my name is Mel ... ????

I was just trying to make it clear that it doesn't mean it is drawing 36v ...

I would have thought they would have been better if with an onboard genny that you get on small boats
