All kinds of video on You Tube to power homes from an EV for emergencies. Here is a short one.There was a mention about Exportable Power in today's live stream. Are we going to be able to hook up MME to power our home when needed ? Unfortunately I couldn't screen grab the presentation slide.
Here's the comparison:But my question was: how long and what will 88 KW from the MachE battery power in your house?
Are we talking about 1 day, 2 days a week or just hours?
In other words in the real world is this reversibility meaningful or is only enough power to keep a few lights on for several hours until power is restored?
88 kWH battery vs 6.6 kW solar array: The Mach E ER battery holds 13 1/3 hours of power from the solar array @jineshkj has on his house. So, it is probably about 1.5 days' power. If you are running the battery as an emergency backup, that probably means a few days on pared-down power use.I have a 6.6 kW solar and it will be good if I can charge my car with the excess energy. And of course, I don't have to buy a generator if the car can power my house.
That's cool but expensive. Alibaba has the 3kW system for $2,600-2,800 and the 6kW for $5,000. It's also limited to CHAdeMO.All kinds of video on You Tube to power homes from an EV for emergencies. Here is a short one.
Agreed. The question is whether you feel the need to maintain your entire home electrical system during an outage or just keep critical systems on. You can do the latter a lot cheaper with extension cords.Thanks:
Prior to my whole house 20 KW standby generator, I had a gas powered Mistubishi 6 KW generator. It was able to power my refrigerators, freezers, a TV and about 12 lights and if I turned off the lights a range for cooking but of course no AC, dryer etc. So I would image I was using about 3/4 KW per hours.
With the MachE, 88 KW that would be a bit more than 1 day.
But to do that, would require:
If you do not get a transfer switch, they you would wind up running a whole bunch of extension cords from the inverter to your appliances. Do not think that is viable solution.
- an inverter capable of handling 6 KW
- a transfer switch if you wanted to power your whole house
So I guess the MachE could power a few appliances: beyond that you would need a transfer switch
Using a Nissan Leaf EV for emergencies.Depends on the type/size of Home and Family. My Grid Tied Solar (36 - 300 Watt Rated produces not more than 7.6 KW/hr at daytime peak). I have 11 KW of battery backup connected to this with a 7.5 KW inverter that will power half of my Home (a few lights, outlets, ventiliation Fans, Refrigerator, etc.) for 18 to 36 hours of power outage.
