    NE1 seen this Pure Sine Wave inverters?

    http://www.donrowe.com/inverters/puresine_300.html

    Wonder if they are that much better and worth it?

    Nice.... but the price is so high on it, I don't know.... too bad we couldn't incorporate something like this w/ the OPUS.... that would be worth $200 - $250.00 dollars for the whole raw deal!!!
    New CarPC on the way again I think. I miss my old one!!!

    For inverters, Pure Sine Wave is the best. However, if you're powering a PC, then you still don't want to go from DC-AC-DC. The Opus is still probably the best thing to do.

    I think with pure sine wave you can power a UPS, if so its shutdown controller could do everything for you just have it connected to the ACC

    That's good idea.
    You can have the UPS software shutdown the computer when AC is removed after xx minutes but then how would you turn the UPS on and off?
    I think SDC is still needed.
    With the price of a pure sine wave inverter and UPS and installation size, OPUS is much better but it only 150W. dammm.

    My point exactly. the Opus costs nearly 200 dollars, and ONLY puts out 150W DC. That's why I opted to go with an additional 65AMP alternator for the computer (replacing the AC Compressor), a 300W (rms) Inverter (to 120vac) and then a 450W/700va (volt-amp) APC UPS (APC model SU700-NET, pure sine-wave output, over/under-voltage correction, Power Chute etc). Only problem I have right now is the UPS won't power up in car even when fully charged. I think it has something to do with the "Site Wiring Fault" protection that it has built into it. The "Site Wiring Fault" light comes on, so I think I need to make sure that:



    • All Cases Commonly Grounded (DC->AC Inverter), UPS, & carPC
    • Negative Prong on 120vac is Connected to Common Ground (Car Frame)
