Yup, you can charge your lithium-ion battery using solar panels. This is especially for off-grid applications and for use in remote locations where grid power is unreliable or simply not available.
To charge a lithium-ion battery using solar panels, you will need a solar charge controller, which regulates the voltage and current from the solar panels to prevent overcharging and damage to the battery. The solar charge controller typically includes a charging algorithm that adjusts the charging voltage and current to maximize the charging efficiency and protect the battery from overcharging and undercharging.
It's important to note that charging a lithium-ion battery requires a specific charging profile, which differs from other battery chemistries. Therefore, it's important to choose a solar charge controller that is specifically designed to charge lithium-ion batteries, and to follow the manufacturer's guidelines for charging the battery. Additionally, it's important to choose a solar panel that can generate enough power to charge the battery within a reasonable amount of time, and to size the solar panel and battery appropriately for your specific application.
Do I need an inverter when charging my lithium-ion battery with solar panel?
It depends on the specific application and the voltage of the battery you're charging. If you're charging a 12V or 24V lithium-ion battery, and your solar panel generates the same voltage or higher, you may not need an inverter. In this case, you can connect the solar panel directly to the battery using a solar charge controller, which will regulate the voltage and current to prevent overcharging and damage to the battery. However, if your solar panel generates a lower voltage than your battery, or if you are charging a lithium-ion battery with a different voltage than your solar panel, you may need an inverter to step up the voltage to the appropriate level.
An inverter can convert the DC voltage generated by the solar panel into AC voltage, which can then be converted back to DC voltage at the appropriate level to charge the battery. In this case, you will need a solar charge controller that is compatible with the output voltage of the inverter, and you will need to follow the manufacturer's guidelines for connecting the solar panel, inverter, and battery. It's important to choose the appropriate equipment and follow the manufacturer's guidelines when charging a lithium-ion battery with a solar panel to ensure safe and efficient charging, and to avoid overcharging or undercharging the battery.

I have the Harbor Freight 100 watt solar array. I feed that in to a MPPT (Maximum Power Point Tracker) controller that I got from Amazon to charge the (older) 12V Full River that was sold on Jag35. I didn’t drain the pack and do a full solar recharge. But looking at charge rates, I think it will charge the pack in about 2 1/2 to 3 hours with full sun.
