It depends on where you are and what the sunshine is like. I was in a place that got 9-10 hours of good sunlight and had clear days, so I was able to get 3 full charges and most of a 4th, but I can usually get 2 full charges on a clear day in most places I’ve been. My 700watts of panels were getting over 5-600w of hourly production for a good 4 hours.
If you charge your car off of it, the car can take the full battery in about 2 hours. Set the charge rate on the lowest setting and trickle charge off the solar.
You could scale up solar panels, if it’s worth the hassle to setup and break down portable panels, but there isn’t enough real estate on the vehicle to get much more wattage . I have 250w mounted on the top of the car and a fold-out 450w panel that I put across my hood and windshield.
Oh… and I have an wcoflow delta 2 battery… the inverter is built into it and I can charge and discharge at the same time.
Ah yeah, the ability to pass power in both directions at arbitrary rates seems pretty important for that use case. Otherwise you’d have to charge the battery with the sun, discharge the battery into the car (while presumably wasting good sunlight). The setup you have sounds like it avoids most of that.
So a good sunny day is good for what, 3 kwh into the car?
I’ve gotten as much as 4, but 700w of panels can vary… shade and heat play a big part in it. I also wasn’t super vigilant of putting up my portable panel, unless I knew I needed the power. When it was up, I generally got about 2.5, but it performed better when I was in places like the Mojave desert and the sun was completely unobstructed all day.
I also charged at a lot of level 2 chargers across the country, that are usually free, and could put power back on the 2kwhr pack from the cigarette lighter outlet in the car, so I generally stayed topped off before the sun even started shining. That’s why I didn’t always use the panels. Not necessarily something to plan into a daily routine if you aren’t traveling. It was a trade-off from having a level 2 chargers at my house.
