KC5 PV Charge Controller Instruction Manual
4.1 Electro-management
2 Control modes are optional:
●Lighting Mode (Default Mode)
Under this mode, if the voltage reaches the one that Lighting Mode requires when Light gets
lower enough, and KC5 will automatically switch on the loads after 3 minutes time delay
●Normal Mode
Under this mode, users need to turn on/off the loads manually.
The Loads will keep being charged unless Protection Status is activated.
See details in 5.
4.2 Battery Charging Management
Management proceeds Precharge, Voltage Limit, Float Charge according to different Initial
Status of Batteries
Pre-charge works after deep Discharge, in case of a shock to the batteries from initial impact
current.
Efficient PWM begins to charge after a certain charge from the battery, and turns to Voltage Limit
Charge when goes into the limited line.
Float charge begins and keeps its status at the end of the process. “Full” LED turns on.
Float charge will keep working to recover the loss from self-discharge of the batteries.
Battery Temperature Compensation is functional at this same time
Voltage Valve’s Value of each reference point to be recovered by this function.
Batteries’ Valves’ Values falls down when temperature gets up.
Too high charging voltage will lead harmful gas and water missing of the batteries when
temperature gets too high.
And it will be undercharge to the batteries when too low temperature.
Temperature Compensation will automatically adjust the Charging Voltage at that moment.
The range of Temperature Compensation is -20℃--50 ,℃it is not available when out of this
range.
It keeps Final Charging Voltage never exceeds to the one required.
Efficient PWM mode keeps batteries working at the best status, which much extends their lives.
4.3 Working Indication
6 LEDs for indications
①Charging, green LED: Charging, charging current exists
②Full, green LED: Fully Charged
③Low volt, red LED: Flashing for Alarm, keep red for protection’s activated.
