    I connected mine to a refrigerator that I have in the garage and lowered the thermostat until the compressor motor started. The voltage dipped significantly but the inverter continued to run with no problem.

    I've read this discussion with great interest. I am planning to hook a Xantrex Prowatt SW1000 True Sinewave inverter to the 12v battery. But when I looked at the 2010 Prius cables to the 12v battery, they look very thin, and don't look like they could carry much current. According to the Xantrex manual, the inverter should deliver 900w continuous, and 2000w peak. They suggest using 0 AWG cables from the battery to the inverter. And I'm thinking a 150A ANL fuse on the positive cable from the battery to the inverter should protect the Prius 12v battery OK. But I'm concerned that drawing 900w continuous may deplete the 12v battery, if the Prius dc/dc inverter that powers the 12v battery is not strong enough to keep up with the current draw. And my concern comes from seeing those tiny (?) wires of the Prius to the 12v battery (what size are they, actually?)

    So, what can I realistically draw continuously by connecting my inverter to the 12v battery in the 2010 Prius?

    There have been many threads on here that address connecting an inverter to the 12V battery. Search on here for details and I think you will find all of your answers.

    I have spent hours reading the many threads here, but am concerned that:
    - the cables to the 12v battery on my 2010 Prius seem very thin. Are the cables on the older cars heavier?
    - many of the posts say, "I suppose..." That doesn't give me confidence. (n)
    - I wonder how much I can draw continuously (not just for hours, but days)?

    The fuse in the car's DC-DC connection to the 12V battery is 100A, so your inverter fuse should be a lower value than this.

    There's a current capacity table at Genuinedealz which rates 6AWG wire at 120A. For short runs you shouldn't need anything heavier.

    Here's one of the more comprehensive threads on using an inverter with the Prius.

    Might be a good idea to measure the gage of your cables so you can be sure what you are working with. Your post will be more on topic if you post in one of the 12v inverter threads or open your own thread. I haven't even read the 12 volt threads because it is very different from connection to the traction battery.

    Thanks. It's actually 125A, and I looked at the battery, and it has a 140A fuse in the positive side terminal connector. So I will definitely not use a 150A fuse as I had planned.

    OK, thanks, there are so many threads here I figured this thread was fine, but I can start a new one.

    So does the eBay unit come with cables or is modified?

    They both list the same model number and specs unless I am missing something.

    Edit- they are different model #'s PWRI200012S vs PWRI2000S240VDC

    The one for the Prius comes with two #10 wires with ring terminals that fit the inverter DC input on one end and the HV battery output connection on the other. The inverter DC input range is 180-240 VDC to match the Prius HV battery.

    You will need to add the correct inline fuse holders and semiconductor fuses as described in AHetaFan's write up to properly protect the wiring between the HV battery and inverter unit from a short circuit fault.

    As for the model numbers I think you are missing something. The PWRI200012S indicates a 2000W, 12oVAC output and 12VDC input as noted by fuzzy1 above. The AIMS Prius unit is custom made to match the HV battery voltage.

    The fuse you linked is 25 amp. I recommend the 15 amp also sold on that site Semiconductor Fuses | Ferraz Shawmut or Mersen | A60Q15-2 | Allfuses.com
    Total cost with shipping may cost you less from Zoro Tools where I bought mine. Zoro Tools Industrial Supplies Search for G3537256

    You have linked the same fuse holder I used which should be fine. The fuse holder is also available from Zoro Tools if you would like to order everything you need from one place. Search HEB-AA

    Thanks for the heads-up!

    When one looks at the huge price differences for the same devices on AllFuses vs Zoro Tools, plus the shipping cost, if one buys three fuses (always nice to have a spare) and two holders from Zoro for $52.43 the shipping is free -- that looks like the best deal.

    I am presuming that one fuses both sides of the line, though that's debated in the world of mobile Amateur Radio, I don't see a down-side to extra protection.

    Thanks, David

    I goofed once and plugged in my inverter while the car was powered on. The little bit of arcing between terminals as I made the connection caused both fuses to pop. I have two spare fuses now.

    Good point - I'll get a pair of spares.

    New info for those reading through this thread later. I've been told of additional brands/models of UPS, that are compatible with the Prius traction battery. I added the info to the end of the thread linked in my signature. I'm still using the APC SURT line.

    ConVerdant Vehicles has the Aims Prius 2k Inverter on sale $100 off on their site through Jan 7. I mention this because they may be able to help arrange professional install for anyone who does not want to do it themselves. Plug-Out Kits

    The eBay price has dropped also.
