I know I can install a more powerful inverter with a new lead, but has anyone replaced their stock power inverter with a higher quality pure sine wave inverter of the same or maybe a bit more power? It seems Ford cheaped out a bit with the one they used as stock, I intend to use mine somewhat regularly for low draw items, would be nice ot have a higher quality output without having to do too much wiring.

 

The wiring (both DC and AC) is barely sized for what's there... you could put another inverter in that location, but you'd need to add new wiring anyway to accommodate more input power on the DC side and more output power on the AC side.

 

Thanks, I figured that may be the case. But is there a better quality more efficient after market available that would work better with the same voltage?

 

It's not voltage... it's current. The voltage is fixed (12VDC in, 115VAC out). A typical inverter is going to be about 90% efficient. Even if Ford used a terribly ****ty inverter with 80% efficiency, you'd be looking at 400W / 13.8V / 0.8 = 36.2A on the DC input side. If you magically found a 100% efficient inverter (a physical impossibility), you would only realize a 20% increase in output power, or 499.6 watts.

If you want MOAR POWARZ, you really need to do a complete install of your own.

 

As you can tell, my expertise does not lie in electronics! Thanks.

 

The easiest thing you can do is to get an inverter you can just plug into a 12V socket. The second easiest thing you can do is to permanently wire in an aftermarket inverter separate from Ford's setup. Rewiring Ford's setup with an aftermarket inverter will be the most difficult.

 

I'm not sure what fuse size is on the power outlets, but I would expect an inverter with higher capacity than stock to need more current that it would supply. Most vehicles I've looked at in the past only have ~20 amp fuse. I can't imagine it would be more than 40. The sort of easy way for occasional use is to clamp it on the battery terminals with the hood open. The inverters I've seen are fused for protection.

 

I need something more powerful to. Won't even charge my sons laptop.

 

 

Agreed.
