Soft Charge- When batteries suffer an over-discharge, the controller will softly ramp
the battery voltage up to 10V.
Bulk Charge-Maximum current charging until batteries rise to Absorption level
Absorption Charge-Constant voltage charging, and battery is over 85%.
Equalization Charge*-Only for WET battery type, when the battery is deeply drained
below 10V, it will automatically run this stage to bring the internal cells as
an equal state and fully complement the lo
ss of c
apacity. (LiFePO4, LTO,
LI-95, Gel and AGM battery do not run Equalization charge)
Float Charge-Battery is fully charged and maintained at a safe level.
A fully charged Lead acid battery (GEL, AGM, WET battery) has a
voltage of more than 13.6 Volts; A fully charged LiFePO4 or LTO battery
has a voltage level of 13.4V.
Lithium batteries wake-up-If the BMS under-voltage protection has been triggered in
the lithium battery mode (LiFePO4, LTO or LI-95 ) , Pressing both VOLT/AMP
and BATTERY TYPE button, the solar controller will wake up the "dead" Lithium
batteries, The LCD display will show the rotation of moving bar in this wake-up period.
The 6 LED’s indicate the
