12V and 24V solar panel systems are still the most commonly used, but 48V batteries are becoming prevalent. If you want to buy a 48V battery, you have to use the right solar panel sizes and voltage to get the best charging time. Three 350 watt solar panels connected in a series can charge a 48V 100ah battery in a day.
A 48V Solar Panel Charge Controller is necessary for a 72V PV Array Input and 48 Volt Solar Battery Bank Configuration. The advantages of a 48V Solar Battery, such as faster charging and storing more power, cannot be compared to 12V or 24V batteries.
Three 350 watt solar panels connected in a series can charge a 48V 100ah battery in a day. For cold areas, the panel VOC should be between 67 to 72 volts, and for hot conditions it should be from 80 to 82 volts. An MPPT charge controller works best for 48V systems.

For cold areas, the panel VOC should be between 67 to 72 volts, and for hot conditions it should be from 80 to 82 volts.
The answer depends on how much power the solar panels have, how much sunlight is available, battery capacity and how fast you want to have the battery charged. A 100ah 48V battery holds 4800 watts, so you need solar panels that can produce at least that amount. 3 x 350W solar panels can charge the battery in 5 hours.
Midnight Solar says +30%. A 48V battery bank will want to charge at anywhere between 50-59 volts, and for lead-acid that needs equalization, up to 64V. So, you need a panel string that is ~ 58V X 1.3X = 75.5V. So, wire your panels to put out at least 75-78V, and you should be fine.
