    I purchased an AIMS 2KW, 180-240 VDC to 120 VAC, inverter in 2013 and installed it in my car with a quick disconnect connected to my HV Battery. I also made up a SO cord to connect between the inverter and the electrical panel. I tested it with my garage refrigerator at the time and have not used it since.

    This weekend we had a visit from Hurricane Matthew. The coast of NC actually fared better than the inland counties who are still dealing with flooding.

    We lost power Saturday night about 9:00. Typically it does not take Duke Energy long to get our power back once the storm and high winds subside. So we went to bed early thinking the power would be on by morning.

    Sunday by noon it was obvious we needed to get power to our inhouse refrigerator, so I hooked up the Prius to our electrical panel and in about 30 minutes we had the refrigerator running and power to the den receptacles. Luckily it was cool and dry so we were doing fine. I tried to turn on the garage refrigerator but the inverter shut down on the inrush.

    Duke had our power restored just before dark so we were very lucky as thousands were still without power in our area.

    So the Prius inverter came through in an emergency and saved a refrigerator/freezer full of food. It was really nice to have this option available and ready to go.

    A few neighbors had to come by and check it out!!

    By Monday we had the yard cleaned up and pretty much back to normal. A lot of families are not as fortunate, especially in the flooded areas. Some rivers are not expected to crest until Friday. Please pray for the safety of these families.

    The first responders have done an incredible job along with friends and neighbors helping each other. It has been great to see how people respond to their neighbors needs!

    You didn't specify, but be sure the car is in the Ready mode to avoid depleting the HV battery.

    If connected properly to the battery, downstream of the cutout relay, this is automatic. No Ready, no juice to inverter, no battery drain.

    See fuzzy1's reply above. It never crossed my mind that I would need to specify this!

    Well, there are many word games and semantics that people want to read about in a sentence.
    You did a very good job in preparing for an occasion like the one just passed.

    You don't mind share the link where you bought the inverter?

    I just checked eBay but could not find the inverter that I purchased. It was modified for the Prius HV Battery with a 180-240 VDC input and 120 VAC output. It has been 3 years since the purchase.

    The above link is by AhetaFan that describes his installation and the one that I followed. I hope this helps.

    That seller had it available for about a year. It is now long gone.

    I'd like to find a a way of doing this without it costing more than $500. It would be nice to use the Prius as a generator when dry camping or during a power outage. Some of the higher KV generators could even run an RV AC unit. Sometimes when camping the kids need a break from this Texas heat.

    Put the car in Ready mode and turn on the A/C. Works just fine. Getting a 200vdc to 110vac inverter will be expensive. How much capacity do you need?

    I have a Prius C. Does anyone know how big of an inverter I can use? I found a good deal on 1000w sine inverted. I was going to hook it up to the 12v battery.

    that will work, make sure you use the correct cable size.

    I remember back in 2008 when I bought my first Prius people were talking about tapping the Prius for power.

    Again, just to be commercial, look at PlugOut Power.. [ConVerdant Vehicles reopened as..]. Inverters for the Prius [and other hybrids] traction battery.

    Greetings Bisco. I would like your opinion, and or suggestion about the possibility of using an eg4 solar unit on prius as home backup power. Its advertised as 120 to 500 vdc input capacity and the 3000 watt unit is only 18 lbs and only 750 dollars. Their split phase unit is half the price of the plugout power and is a 6000 watt unit.

    I'm concerned about the fluctuating voltage input when ice kicks in, but have the idea to take supply input to inverter from the opposite battery posts than what go to the cars MG unit thus using the battery as a buffer for the rapid voltage fluctuacion. What do you think?

    EG4 doesn't make any inverters that would work properly on a prius battery.

    I ended up installing two 85ah batteries each running its own 2,000w pure sine inverter. has enough power to cook on the air fryer and run all the add on electronics with the car of for a solid hour demanding on how high I set temps. having a phev, I have actually been able to charge at the charging station, car is not in ready, and use the inverters never depleting the 12v batteries.

    my setup is for overlanding and having the ability to be self sustained in the middle of no where is why these mods were done, just thinking for your usage it also might work well.
