[QUOTE="bubbagumper6, post: 6947709, member: 567719"] It depends on a lot of things man. There's not just a set threshold that if you cross it your system will instantly fail. It's all about headroom. Sure you could probably burp a couple thousand watts on that system if you did it instantaneously, but any length of time and your going to get horrible voltage drops. Batteries can help with voltage drops but only to a point, you'll still drop to whatever their resting voltage is and possibly lower if they can't handle the load. The more batteries you add the larger the load you put on the alternator. You could seemingly get away with thousands of watts if you have the appropriate battery bank however the load put on your alternator will almost certainly shorten it's life, if not kill it very shortly. I'm more about headroom than saving a buck, I'd rather have the capability to run 4kw and only actually run 3kw, and not be running my electrical system at 100% of it's capability all the time. Anyway, that being said, a 105A alt is about average, if you threw a good batt in there you could probably get away with 1000w, go with two batts and you could probably approach 2kw. But like I said all of this puts a large load on your alt. I wouldn't cross 1200w without upgrading my alt but that's just me. I've seen burnt alts and blown amps (due to low voltage) so I don't take risks anymore. And dbeez I really don't give a shit if you disagree. [/QUOTE]
