About How many volts of solar panels are used for a 48v battery pack

If you have a 48V battery like theWeize 48V100ah, what voltage must your solar panel be? How do you match these panels, batteries and charge controllers when they have different voltages? It can be confusing, but here we will simplify everything. The VOC (voltage open circuit) of your solar panel must be 1.4 to 1.8 times.

Regardless of battery type, the solar panel voltage must always be greater than the battery. With a 48V battery, your solar panel voltage must be.

PWM and MPPT charge controllers have the same function, protect the battery from overloading, overcharging and otherwise keep it running the way it is suppose to. A 20A MPPT charge controller can handle a 48V system up to 1000.

The figures above are for fully charging a battery. If you are using a lead acid battery (FLA, gel, AGM), it is probably 50% filled. At least it should be.

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.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. An MPPT charge controller works best for 48V systems.

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.

To be safe for a 48V bank the voltage should be about 60V but you must also keep it below 100V which is the max open circuit voltage that charge controller can handle.
