Switching Between Equalized and Float Charge for Lead-Acid Batteries
●
You can manually switch between equalized charge and float charge when
the system works in manual control mode.

When the float charge conditions are met (for example, time for boost charge
expires), the batteries automatically switch to the float charge state.
