Re: Charging My 2016 Leaf With Solar

Is your system grid tied or off grid. If it’s grid tied why bother? If it’s off grid you are going to need just a couple, three, forty more panels. If it’s just for fun, enjoy!

Also keep in mind an inverter putting out 1440w is lucky if it is 85% efficient, so your realistically pulling 1650w from the batteries.

I am off-grid because I wanted to experiment with solar a little before making a big investment (like what I see so far). Almost all my Leaf charging is done at home with a Level 2 cable connected to outlet that an electrician friend wired up for me.

It would be great to hear on this thread from anyone that is charging their Leaf and has a full on-grid solar system, any observations they may have. I suppose they could claim that they "run their car on sunshine." when they charge at home.

We have 3kw of solar with batteries and we use either the larger clipper creek charging at the full 6kWh rate from the grid during off peak or we have a 20a 240vac outlet with a smaller adjustable EVSE that is fed from our inverter to charge the car. I would estimate about 1/2 of our Leaf charging come straight from PV. If we need to charge on peak we will just use our PV / batteries to charge up at 14 amps at 240vac, pulling nothing from the grid. It is nice becasue the EVSE can be set anywhere from 6 amps at 240vac to 30? amps, but I usually leave it set to 14 amps on the 240 vac plug. Our inverter is a xantrex 6048, meaning it is 6000w continuous supply at 240vac and is fed from 48vdc battery bank consisting of eight L16's or approx 400 amps at 48v or just under 20 kWh of storage. I did keep our older smaller xantrex 2000w 12v sine wave inverter as well and that is running from a few older L16's as well, backup to backup...

The extras components you have to buy to be off-grid makes it a considerably more expensive choice that on-grid regardless of number of panels. Look into SolarEdge optimizers with an inverter. That way you can grow the system at your leisure.

I would agree, unless you need the backup and understand the additional cost, complexity, maintenance and reduced overall efficiency I would suggest a grid tie batteryless system.
