What voltage should I charge my solar panels with?
If you have a 50 volt and 10 amp current coming from your solar panels but only want 15 volts, the PNW charge controller will send a 15 volt 10 amp current into your battery. This is less than ideal due to the wasted energy.
How many solar panels do you need to power a car?
Luckily, the average driver travels 37 miles per day, which translates to about 12 kWh of electricity. So, a more realistic number would be 12 solar panels. Remember, this is also a conservative estimate, so if your solar panels are high efficiency, the number of panels may drop even lower.
What voltage should I charge my car battery at?
When we talk about recharging batteries, two parts of the electric current are important: amps, and voltage. If our battery bank runs at 12 volts, we want to recharge it with a current at or a little above that 12 volt rating. Once we’ve reached our desired voltage in our charging current, additional amps result in a faster charge time.

How much power does an inverter provide to a SLI battery?
According to others, the inverter can provide up to 1.2-1.5 kW to the SLI battery, so if your panel was supplementing the power to the battery, it would reduce the load from the inverter. All this is a lot of work of course and I'm not sure if it is even wise. Still, its sounds like a possibility...
What is grid tie solar?
It acts as a supplemental power source to your home and if you are not using all of it, it feeds to the grid. Hence the name, "grid tie".
Can you use one panel on a Chevy Volt?
You can't just use one panel yourself, because the cigarette lighter plugs most likely can't charge the main battery and connecting it to the battery ports directly isn't really a good idea. We have a 6kW panel array on our house, this is plenty of power for our house and to charge our Chevy Volt.
Can you use 12V panel on 12V battery?
Nice theory, but in practice you can connect a "12V" panel across a "12V" battery. Note that maximum power is not the point if you are storing a car for a few months, it's just keeping ahead of the "ghost currents" that drain the battery over time. A daily trickle that adds up to be a bit more than the clock/alarm/etc. use is perfect. Works very nice on my truck that gets used a few times a year, I haven't even disconnected it while driving for several years.
How many volts does an electric car use?
