How big of a Inverter can I run with a single battery..?? (1 Viewer)

Without any context, here's a quick guesstimate...

I believe the battery that I am currently running is about 90ah. A 1000w inverter (1000/12=83.33) running at full capacity would be an ~83amp load. You'd have a little over an hour of runtime, (off the battery) at full capacity, before the battery was drained.
 
If your engine is running some or all of the inverter power would be supplied by the alternator. If the alternator power is exceeded then the battery will become depleted. So really a function of the load, alternator capacity, battery capacity and inverter efficiency.

If the engine is not running then it is a function of the above except alternator capacity.
 
The instantaneous amps a battery can supply are limited mostly by the size of the wire to the inverter. The amp-hour rating of the battery will tell you how long it can supply the amps. A starting battery should not be used with an inverter because it will be damaged by repeated deep discharge. Even a deep cycle battery should not be regularly discharged over about 50-75% capacity if you want it to last.

Volts X Amps = Watts
 
1000 watts..??

More..??

Thanks
Seemingly simple question but there are crucial variables that determine your true run time for a given load as determined by Puekert's Law, with true run time usually being significantly less than a basic linear Amp Hour calculation. Have a look at the run time calculator at Batterystuff.com.
 
Sorry for my lack of context

I'm exploring a Hydro pump to deploy and lift a wheel chair carrier (600pound max loaded), I can fabricate a raising rate linkage, to gain some mechanical advantage) but the type of high flow pumps are mostly make in 110Volt (very limited budget) (Looking on the OEM rear suspension pump too) obviously it will be a momentary use and i guess the vehicle will need to be running at somehow high RPM's
 
Thank you Much better Forum Thanks..

this is for a single battery LC100 (2000) and pretty basic model (No idea if the alternator and other component change with the more luxury models)
 
No your alternator is the same as other 2000 LC100's. The LC80 has an 80A or 90A Alt and I think the 100 is the same. It's a good unit. Mine puts out as much as 15V to a partially drained battery, and 14.8V routinely when first started. This voltage drops gradually over 20-30 minutes of driving to around 14.2. With the available amperage that's a nice charging system we have IMO.
