The lowest voltage required to charge the battery is: 10.5 Volts if your battery is rated at 12V (nominal); 21 Volts if your battery is rated at 24V (nominal); 42 Volts if your battery is rated at 48V (nominal); Or, you can let our MPPT calculator do all the work for you.. Since it''s a 200W solar panel, and, for example, if the battery is rated at 12V:
For instance, at night, when Solar Irradiance is 0 Watts/m², the solar panel, regardless of its rated power, will produce 0 Watts. However, in some situations, when the Solar Irradiance surpasses 1000 Watts/m², an occurrence known as "Over-Irradiance," a 100-watt solar panel might generate more than 100 Watts of power.
