2013 Plug-In to Charge Bluetti Battery Bank

I would personally use an inverter gas generator, rather than mess with something that can get you out of there.

You can install this, because the gen4 DC-DC converter is good for 1000W, don't know about your gen3.

cost is about the same and your not messing with your car.

if you search here, there's a thread on tapping into the hybrid Prius battery. might provide insights into the plug in battery.

My Bluetti AC180 easily powers the fridge overnight. It's a newer model Frigidaire side by side. The new ones consume less power and energy. The defrost cycle is still a big drain, but I've found no easy way to defeat in for the duration of the outage. Maybe open cycling power can give you a couple hour respite? I forget. Easy to do when you have power, lol.

I recharge with a Honda inverter generator 2000i.

 

Using your Prius to power stuff in your house up to ~1000 watts is as simple as wiring an inverter to the 12volt battery. I prefer a 2000w inverter because everything runs better at only half its limit. And because Bluetti is simply a battery and an inverter in a box, you should be able to wire it's 12volt inputs directly to the battery. The challenge will be how Bluetti limits the amount of amps it can draw from an external 12v. Perhaps there's a function in the settings that allows you to set it to pull max amps?

 

All you have to do is unplug the "hot wire" for the defroster cycle - but you'll run the risk of icing up and occluding air flow thru your evaporator.

 

I'll have to look again. Everything's digital. This would just be for the duration of the outage.

 

Find the controller and look for hefty relay and wire; that should be the heater circuit. As long as that wire doesn't go to the compressor. Those should be the only hefty wires in that unit. You may want to put it on an easy to reach switch - so you don't have to move it every-time power goes out.
