Sine Wave Inverter Anomaly
After following this recent discussion about how to best utilize a sine wave inverter for RV use I decided to go ahead and buy the 1000 watt model mentioned in this discussion since it was on sale for...

By the way, SoundGuy,
how did you wire that wimpy little case ground post on the inverter. Separate wire to trailer chassis or just a jumper to the inverter's battery neg post (which winds up wired to chassis at the battery).
IIRC a separate wire to chassis is what's recommended?
Sorry I missed this earlier. :S
If you're referring to the inverter's owner's manual it's pretty bleak and says absolutely nothing about that "little case ground on the inverter" - no mention at all, doesn't even show it in pics, nada - so I didn't connect it at all. Further, on Page 4 it warns "Do not connect any AC device which has it's neutral connected to ground to the unit". By extension, that to me also means don't bond the inverter's output. It also "suggests" connecting the inverter to the battery using "25 mm (squared), 90 cm long cables". Checking the American Wire Gauge Chart shown here that tells me I should have used 3 gauge cables no longer than 36" each ... but because I wanted the inverter located inside the front pass through storage compartment each run had to be ~ 6 feet and because the best I could get at the time was 4 gauge that's what I used. However, according to this Blue Sea Chart 4 gauge should be entirely suitable. :h
