Common Q&A
Q: How to install it?
A: (1)Battery --->(2)Solar panels ---> (3)DC load
Q: Why the LCD screen become blank?
A: When the battery voltage is too low, the controller will stop to output(≦ 8V, controller turns itself off, LCD is blank, ≦ 10.7V, 12V output ports are not available); after the solar panels charging, it will re-output when the battery will return to 12.6V.
Q: What battery type is this controller supported?
A: The regulator is only suitable for lead acid batteries:OPEN, AGM, GEL, not for nickel hydride, lithium, ions, or other batteries.
Q: Why does the controller display 14.4V?
A: If the solar charge controller is set to 12V, when the battery voltage reaches 14.4V or 14.5V, the solar charge controller will stop charging and play a protective role. If it does not enter the floating state, please don't worry, the solar charge controller has a voltage limit value, will be not charge if the battery voltage reaches to 14.4V or 14.5V.
Q:How is it set to charge battery during the day and turn on at dusk?
A: Press the [DOWN]button to ON/OF load manully at main display （The load can't be switched manually in the light control state.）
There are 3 options for the working mode.
Mode 1 : [24HR] >> Load output 24 hours
Mode 2 : [1-23HR] >> Load on aftersunset and dosed after setting hours
Mode 3 : [0H] >> Dusk to Dawn
3C standard
Using dedicated chips and dedicated software, can automatically manage the working of solar panel and battery in solar system.
The various parameters set by the automatic memory can be saved in case of unexpected power failure, and the battery power consumption data will not be lost.

Note:
<1> Old batteries may be degraded the capacity after hundereds of cycles, easily drop lower than 8V, which results in the controller will be shut off (LCD screen become totally “DEAD”).
<2>Connect the inverter (DC / AC) to the battery. DO NOT connect to the solar controller.
<3>This controller can only use photovoltaic panels as charging power. Do not use DC or other power as charging power.
<4>The LCD display has an error of 0.2 V- 0.3 V, but this is normal
<5>Indoor use only: the working temperature of this controller is -35°C to +60°C, during hot sunny days, the temperature outside might go up to 60-75°C. Please do keep the controller stay in cool and well-ventilated place to maintain good heat dissipation.
