This solar controller provides multiple charging stages with smart charging algorithm.
For Lead acid battery (Crystal, Gel, AGM, WET and Calcium battery):
Soft Charge – Bulk Charge - Absorption charge - Equalizing Charge* - Float charge
For Lithium battery (LCO, LI-95, LFP, LTO battery)
Soft Charge – Bulk Charge - Absorption charge – Stop and Restart charge*
Soft start -
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.
For Lead crystal
battery type
, the charge controller will deliver two step level of Bulk charge, when the first level
rises the battery voltage up to 14.4V, then switch into the second level of the 10% of the first bulk
charge rate, until the Lead crystal battery voltage up to 14.7V.
Absorption -
Constant voltage charging and battery is over 85% for lead acid battery; the Lithium
battery (LCO, LFP and LTO battery) will close fully charged after absorption stage, for LI-95 Lithium
battery will be charged 95% Capacity.
Equalization *
- Only for WET or Calcium battery type, when the battery is deeply drained below
10V or every 28 days cycle, it will automatically run this stage to bring the internal cells as an equal
state and fully complement the loss of capacity. (Lead crystal, Gel, AGM battery or Lithium
batteries do not run Equalization charge)
Float Charge or Re-Start charge* -
Battery is fully charged and maintained at a safe level.
A fully charged Lead acid battery (Crystal, GEL, AGM, WET or Calcium battery) has a voltage of
more than 13.6 Volts; if the lead acid battery voltage drops to 12.7V at float mode, it will return to
Bulk charge, Lithium battery will stop charge after Absorption stage, it will restart to bulk charge if
the voltage discharge less than 12.0V for LCO battery, 13.0V for LTO battery, 13.3V for LFP or LI-95
battery.
Remarks -
This controller provides an override function (force output delivery) for some heavily
discharged Lead acid batteries (Low to 0V), or for some LiFePO4 batteries which are protected by
BMS due to over-discharged. Press
BATT / -
button for 3 seconds to wake up the Lithium battery
(activate the BMS against protection) or override the Lead acid battery.
