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.
To charge the battery with either PWM or MPPT, the solar panel voltage should be more than 48V, if I understand correctly. Thus I can either boost the voltage to more than 48V (inefficient), or connect multiple solar panels in series (e.g. 3x18V=54V).
use a MPPT boost solar charge controller that will handle the panel output, boost the voltage to the level needed for battery charging and prevent overcharging of the battery This is the low-cost version that will hopefully still yield good results. After construction and testing, I'll update you how well it works (or not).
Thus I can either boost the voltage to more than 48V (inefficient), or connect multiple solar panels in series (e.g. 3x18V=54V). The panels will not necessarily be oriented in the same direction, and shadows may be cast on individual panels, so I guess connecting them in series will make the whole array highly sensitive to the environment.
Compatibility: 48V lithium battery systems can typically directly replace the old lead-acid battery systems due to their similar system voltage. This facilitates upgrading the existing lead-acid battery system without having to replace other components.
In a photovoltaic system, solar energy is robust, and the battery gets charged, the inverter converts the direct current produced from the solar panels into alternating current for the usage of electrical appliances. The automatic transfer switch of the inverter gets set to solar power mode.
