Good info.
A problem is if your solar panels are at your house during the best charging hours of the day (when the sun is out) most people are at work.
True. Then it requires having enough batteries to replace the energy needed for your daily miles, plus the losses of going though the batteries instead of the inverters built in MPPT charger.
A well done video! I'm retired and don't drive every day. I have been charging my 2012 LEAF on level one every since I owned it. It works fine for me because I don't drive every day and when I do its usually only about 10 miles.
No gas stations!
My average is less than 10 per day. Remote work, so lvl 1 charging works fine for me.
Great Video Steve, as you know, my level 1 charging setup is very similar to yours. This is my motivation to upgrade to level 2 charging.
Yes, I have a Growatt 5000ES I was going to use for that, but the new EG4 6000Ex is tempting.
You're using an Anker, right? Can they be paralleled for 240 volts?
@@ReelClearMediaLLC I've got a Growatt 3000 LVM-ES and a single EG4 Lifepower4 battery that I use to level 1 charge my Leaf. It's been a great beginner system and I've captured nearly 2Mw of solar in the last year. I also use the Zencar adjustable EVSE. I have some Anker stuff too that I mostly use with our RV or other portable uses. The Anker 767 (F2000) does not allow 240v output like the Ecoflow Delta Pro
@@leafnutz2341 Thanks!
I just bought the EG4 3000 and when I get a battery I am hoping to charge my LEAF with it. I can buy another one and go to 240v. After watching this and seeing the efficiency improvement I may do that. I considered the EG4 6000Ex but my understanding was that it needed 2 batteries to function and it would be a long time before I could buy all those parts. For my modest needs I think that the 3000 will do me fine.
@@Javaman92 In another post you said you drive around 10 miles a day, so you only need 4-5 kWh. If you charge mostly on sunny days in the daytime, the solar battery will only be used to smooth out the power during clouds, or early/late day hours. A lot of days my solar batteries are hardly used at all. When I drive more miles than normal, I''ll continue the charge into the evening or start early morning before the solar is producing much. Then while I'm out with the car the solar can recharge my house batteries.
As Ray says most people work during the day when the power of the sun is best. When coming home you need a battery to start as the sun is down. Then not every day the sun shines and you forget winter and cold weather as well a lot of things should be added to have any idea in total. My parents have 11.000kw on the roof and during winter or rainy days all this "power" doesn't matter as there is NO power. In theory all of this is great and don't get me wrong i am not against solar or wind but we live in a world where we need power every minute of the day and night and this will never be the case with these two sources.
That is why you have the Grid or a backup generator as a backup, not really theory, just reality. Larger battery banks will reduce those needs, but never end them....just like the Grid.
