LCD Display - Normal function
When the solar input is active and the charging process begins, the LCD will show the
charging status. This can be displayed as battery voltage, charging amps, charged
capacity (Amp hours) and battery temperature (if external temperature sensor
connected)

CHARGING STAGE
The KAPWM30A 12V Regulator has a 6 stage charge algorithm
Diagnose
* – Only for Lithium battery type, subjected to the Lithium battery initial voltage
which will determine if Soft start or Bulk stage is appropriate; if the Lithium battery is
protected by the BMS, the regulator will automatically send a voltage signal periodically
to the battery terminal to activate the BMS, and bring it out of low voltage protection.
Soft start
- When batteries suffer an over-discharge, the regulator will softly ramp the
battery voltage up to 10V, before entering the Bulk Stage.
Bulk Stage
- Maximum charging current will be delivered to batteries until the Absorption
stage reached. For Lead crystal battery type, the regulator will deliver a two step level of
Bulk charge. The first level rises the battery voltage up to 14.4V, then will switch into the
second level of the 50% of the first bulk charge rate, until the Lead crystal battery voltage
reaches
