controller 100a mppt

  Our company offers a revolutionary MPPT solar controller with a three-stage charging system: constant current, constant voltage, and float charging. This state-of-the-art technology ensures that batteries are fully charged and their lifespan is maximized. 

  The constant current stage charges the battery with a steady current, allowing for faster charging and preventing overcharging. Once the battery reaches the preset voltage, the constant voltage mode maintains a steady voltage until the battery is fully charged. This stage takes longer but ensures that the battery is fully charged without causing damage. #100a mppt controller oem

The most common charge profile is the same basic sequence used on a quality mains charger, i.e. bulk mode > absorption mode > float mode.  Entry into bulk charge mode occurs at:

sunrise in the morning                                                           

if the battery voltage droops below a defined voltage for more than a set time period, e.g 5 seconds (re-entry)

This re-entry into bulk mode works well with lead-acid batteries as the voltage drop and droop is worse than it is for lithium based batteries which maintain a higher more stable voltage throughout the majority of the discharge cycle.
