To charge a battery, the voltage of the solar panel needs to be higher than the voltage of the battery. This is because electricity flows from a higher voltage to a lower voltage. In the case of an 18V solar panel and a 12V battery, the 18V panel provides enough voltage to push current into the 12V battery, thereby charging it.
You may utilize an 18v or 24v solar panel to power a 12v battery with the aid of a charge controller or DC-DC converter; an MPPT charge controller will be more effective in this situation. Utilize the Luminous NXG 750, a hybrid inverter that
30Ah x 12V = Watts Watts / sunlight hours = solar panel watts needed. In this case, multiply 30 by 12 and you get 360. Divide 360 by 6 and you get 60 watts. So an 80 watt solar panel like the Sunpals Solar Panel Kit is sufficient to charge a 30Ah 12V battery in 6 hours. If you have a larger solar panel then the charge time will be faster.
