'COMMON' and 'NEG' are alternative references to ground in both AC and DC applications, so seeing as everything else is marked 'LINE', 'BAT', or '+' (which means 12V), I would say yes. White is an odd color choice for a 12V ground wire (usually lighter colors are 12V, darker are ground), but assuming this is a DC-to-AC inverter we are talking about, it might make sense on the output side, though white is usually neutral in AC wiring.

I would, however, suggest contacting the manufacturer to see if they can provide a proper wiring schematic. I fried a fairly new CB radio in an Intertrashable PornStar because it used a white wire for ground, and a green wire for 12V DC, with no labeling

Hope that helps!
