Bulk Charging:
This stage focuses on rapidly charging the battery to a substantial level of charge.

Absorption Charging:
The controller maintains the battery at a high voltage to further increase the battery's charge and compensate for any losses.

Float Charging:
This stage is designed to maintain the battery at a low voltage after it is fully charged, preventing overcharging and prolonging battery life.

Equalization (optional):
This stage applies a higher voltage to the battery to ensure all cells within the battery are fully charged and at the same level.
