    DIY ELECTRONICS A Prius G2 can be a 80 K Watt generator

    for DIY electronic enthusiasts and dreamers!

    Since the Prius inverters have been reverse engineered
    and the control logic is now in the public domain
    (2019) and G2 is cheap we will start to see these projects
    and products this year.

    Prius conversions for stationary
    and or Drive able Hi KW generator
    and Cheaper Home Solar DIY projects
    that work with G2 (80 KW) and G3 (102 KW)

    or You could intercept just G1 and feed it to a new controller
    and have a roving (Drive able) 30kw power station
    fairly cheap.

    (Of course 1/2 all these kw numbers or so, very cool)

    2015 Worthy mention i found this is cool from the vault
    I think he tapped MG into a comercial inverter, i cant tell, but its cool

    2015 This guy is great

    this is not the inverter hack described above
    but most worthy all new electronics (inverter) mention

    thanks for sharing your new inverter work videos (And BOAT CONVERSION)

    Awesome post! I'd love to be able to use my Prius as a true generator for big power outs as opposed to using a 2kw tied to the 12v battery.

    I didn't see this thread at first.

    By mating the transaxle to a larger engine?

    80 kW is 107 HP ....

    Those numbers just don't sound right.
    A generator capable of producing 80,000 watts continuously might take up the whole engine bay.......or more.

    even half those numbers would be great

    on a G2

    MG1 is rated at 30 Kw
    MG2 is rated at 50 Kw

    at 13,500 rpm

    I think

    There would be losses in the Inverter

    The ICE would blow at that rpm

    so

    20kw-40kw i think is reasonable

    That’s great, but the gas engine included with them is only good for 77HP/57kW.

    So without attaching a different gas engine, you’ll hit that limit early.

    Also worth considering the thought that in order to use MG2 for anything, the front wheels have to turn. So if you’re trying to use a car for an auxiliary power capability, you’re strictly limited to what MG1 can do.

    If you do a complete powerplant removal/conversion to stationary system, I’d think you’d be able to convert some power from MG2.

    oops thanks for that , saved by my handy 50% discount

    so 40kw as a stationary is reasonable
    certainly > 20kw at a moderate rev is reasonable
    (with wheels up, thanks for that too)

    So therefore Given the 77 hp ice restrictions it may not be worth it
    using the combined versions for most.

    Ive always liked the a roving MG1 only version for myself
    that's my plan
    for a 20kw (or a little more) or so on a G1
    a switch (normal ev) or (bypass to trunk)
    simple, no inverter hack, another ac inverter in the trunk
    Will the prius ecu's will shut down or limp,
    Hopefully it will just complain wondering where MG1 went.
    (or if it has to be tricked I think I can do that )
    or parallel has options too with a
    (disconnect to the original inverter)
    or the full blown hack will certainly work
    for a power station although
    the best application is a
    as little changes retaining the Prius car

    however I am sure we will see others do much more
    then I am in 2020

    You’ve seen the inverters attached to the 12v subsystem.

    There were others which attached directly to the high voltage traction battery. None currently available, everybody out of business now, but for a while it was possible to get a fairly big 120/240v 60Hz inverter “plug-out” for the prius. You’d leave the car in ready mode, the battery would be drawn down by the inverter until the ECU naturally wanted to start the engine and recharge via MG1. Worked like a charm.

    I think there’s better legs to the idea now than when they were available- more beater priuseses available, more demand for back-up electricity, and the big inverters are now cheap enough to support a fairly big market.

    the problem with the big ones was that there weren't enough prius owners willing to invest, and/or dive into the hybrid battery connections

    I wished I could vet the link to how this guy did this stuff. Very nice. It appears he was using a Prius transmission system with an Otto engine to run the setup.
