Be mindful of the voltages. 24V batteries hold twice as many watts as 12V. If you have these, you can connect two 12V solar panels in a series so they become 24V and a match for the batteries. There are a lot of factors that determine battery charge time, so you have to consider these ahead of time.
You need 4 x 300W solar panels to recharge four batteries in 5 hours. If you only need those batteries every two days, you can recharge them over two days with 2 x 300W solar panels. If the batteries are only 50% discharged. the charge time is reduced to half. Four 12V 100ah batteries at 50% DOD is 2400 watts.
