      Welcome. There is a good thread here on someone who is using a Prius as a generator. I am using using a reconfigured Nissan Leaf pack with a 48 v Hybrid Inverter. "marriage savers" have a a good rate of return.

          It's very hard using a MPPT inverter with a battery, since the MPPT cannot effectively " search" for the MPPT point, as a battery is too "Stiff" of a power source. Sometimes inserting a series ballast resistor (calculated to provide the right power) can help with the MPPT search.

              Ampster, sounds like you rewired your Leaf pack for 48-60v? and Hybrid inverter, so then DC into the PV or the Generator input?
              We have a 2011 LEAF and a couple 2002/2003 Gen I Rav4-EV’s with NiMh packs.
              Sadly(for Nissan) the Rav’s have much more range than the Leaf.
              Anyways, I hope to install a dedicated 360VDC connector on the Rav’s to run an inverter for outages.
              And perhaps utilize the Chademo plug to do the same with the Leaf, though the battery is degraded so much it may not be worth it at this point.

              Mike, thanks for the mppt tip, I hadn’t thought of that at all.
