You need around 400-550 watts of solar panels to charge most of the 12V lithium (LiFePO4) batteries from 100% depth of discharge in 6 peak sun hours with an MPPT charge controller. What Size Solar Panel To Charge 24v Battery?
You need around 350 watts of solar panels to charge a 12V 120ah lithium battery from 100% depth of discharge in 5 peak sun hours with an MPPT charge controller. Full article: Charging 120Ah Battery Guide What Size Solar Panel To Charge 100Ah Battery?
You need around 1600-2000 watts of solar panels to charge most of the 48V lithium batteries from 100% depth of discharge in 6 peak sun hours with an MPPT charge controller. What Size Solar Panel To Charge 120Ah Battery?
Using high-quality components such as cables, connectors, and charge controllers can help to increase the efficiency of solar battery charging. Low-quality components may not perform as well and may reduce the amount of energy generated by the solar panels. 5. Monitor and Maintain Batteries
Solar panels output more than their nominal voltage. For example, a 12v solar panel might put out up to 19 volts. While a 12v battery can take up to 14 or 15 volts when charging, 19 volts is simply too much and could lead to damage from overcharging. Solar charge controllers aren’t an optional component that delivers increased efficiency.
Turns out, 100 watt solar panel will take about 9 peak sun hours to fully charge a 12v 100ah lead acid battery from 50% depth of discharge. how fast should you charge your battery? Deep cycle or solar batteries are designed to charge and discharge at a specific rate, which is referred to as the c-rating.
solar power basics
Solar panels suitable for 12V battery charging generally have voltages rated at around 16-17V. The lower the voltage, the higher the Amps, and the faster current flowing out of the panel, and the faster a battery will charge.

Can I use 24 volt solar panels to charge 12 volt batteries through …
Yes it does. It can accept up to a maximum of 100V in solar to charge 12V batteries. To charge 12V batteries it needs Vbat (12V) + 5V to begin charging and the solar must be Vbat +1V to keep charging. Those solar panels Voc are probably more than 24V so you should be fine!
