| 194977 | 2003-11-28 01:26:00 | One final point. A lot of people forget this, but the more amps you pull on the 230V side, the more amps you pull on the input side. :D A rough guide is: "20 amps in for 1 amp out". (It's actually a bit worse than that, but not far out). It wouldn't take many hours before the inverter started beeping at you, then shutting down (at 10.5 volts or so for the DSE ones). Your vehicle might start with the battery at that, but some wouldn't. :D It will be worthwhile doing a proper installation (with heavy cable and a fuse) back to the battery. A cigarette lighter plug is marginal; the "battery clips" sold with most inverters are worthless. |

| 194978 | 2003-11-28 06:48:00 | Thanks for the advice Graham. Battery power shouldn't be a problem with my installation I have 3 large 12v batteries and a 150 amp alternator. I need it because of the extreme current draw mainly to the hose swager hydraulic pump. Cheers Tedheath |
