Suppose you have a MPPT charging controller in the 12V 100AH lithium battery and departure cabin. Solar panels that need to be charged from 100 % DOD on the same day.
To find the required size panel, enter the following size in the computer.
Battery voltage (V): 12
Battery amplifier time (AH): 100
Battery type: Lithium (LIFEPO4)
Battery emissions depth (DOD): 100 %
Sun charging controller type: MPPT
The required charging time (peak date and time): 15
After all, using the MPPT charging controller to charge the 12V 100AH lithium (Lifepo4) battery in the 15 peaks of the sun, it requires 110 watts of solar panels.
|Charge Time||Charge Controller Type||Estimated Solar Panel Size|
|5 peak sun hours||MPPT||610 watts|
|10 peak sun hours||MPPT||300 watts|
|15 peak sun hours||MPPT||200 watts|
|20 peak sun hours||MPPT||150 watts|
|25 peak sun hours||MPPT||130 watts|
|5 peak sun hours||PWM||760 watts|
|10 peak sun hours||PWM||380 watts|
|15 peak sun hours||PWM||250 watts|
|20 peak sun hours||PWM||190 watts|
|25 peak sun hours||PWM||150 watts|
Using an MPPT charging controller, a solar panel with about 610 watts is required to charge the 24V 100Ah lithium battery from 100 % emissions with 5 peak sunbathing.
To charge a 24V 100Ah lithium battery from 100 % emission in 5 peak sun time with a PWM charging controller, a solar panel with about 760 watts is required.
