Intelligent Solar Charging and discharging Controller
User s Manual
This is a compatible MPPT charge controller PWM intelligent / efficient / energy saving, he not only has
efficient MPPT controller charging function to automatically track the maximum power point, 10% -30%
higher than the ordinary controller charging efficiency, also has standby energy saving, more than 30%
energy than ordinary controller, the standby power consumption of only 10mA-15mA.
1:Product introduction
Solar LCD series a kind of intelligent, multi-purpose solar charge and discharge controller
LCD screen display Battery reverse discharge protection
Easy operation interface Battery reverse polarity protection
MPPT+ PWM charging mode Battery under voltage protection
Parameter user can reset Overload, short-circuit protection
A key to open and close the load Automatic temperature compensation function
A key to restore the factory settings USB 5V charging (for 500mA) for mobile phone
2: Installation Instructions
Installation（Installing wires, first loosen the screw counterclockwise）
1Ready Qi installation tools and materials, and cable. Please matching
suitable cable
2ensure that the current density <4A/mm2 This will help reduce the line
pressure drop.
Check the installation site meets the relevant safety requirements, avoid
damp, dusty, flammable, explosive and corrosive gases
3Install the controller fixed to the vertical plane, see Section V mounting aperture and hole spacing.
In order to ensure a good controller cooling conditions, the controller on the bottom of each
reserved 10cm space
4As shown on the right wiring sequence: load, battery, solar
Battery plate is connected to the controller to be taken to ensure that the load, battery,
The polarity of the solar cell panel and controller
5Before use: external temperature sensor probe into the left of the controller temperature probe
interface probe placed in similar battery temperature. (Line extension must be built-in devices of
the external temperature probe coextensive Otherwise, the controller will control parameters of the
temperature compensation of the error
6Warning: In order to prevent accidents from occurring, install: non-professionals can not be
engaged in loading and unloading operations

LOAD ON 1 H---23H Load control (1 hour --- 23 hours can be set)
LOAD ON 24H 24 hour -is normally open state
0h-light control mode, power supply load after dark, closed after daybreak the load
24h-represents a normal mode, in the case of no fault, the load is always in the power supply state.
1h ~ 23h-light control delay mode, after dark began to power the load, and delay to set the time to close the load.

4 Common fault with processing methods
Battery under-voltage protection Battery normal power supply
a) Under voltage protection and handling: screen display as shown on the right indicates the battery voltage is below
the under voltage protection voltage, the controller has entered under voltage
b) Retaining state, disconnect the load circuit. Using solar panels or charger to charge the battery when the
accumulator
c) After the battery voltage reaches the undervoltage recovery voltage, the controller will restore power to the load,
into normal working condition
1) Overload protection and processing methods：
The screen shown at right load circuit current is greater than the rated current or load short-circuit, overload state controller has entered. Reduce
the load troubleshooting, press the button, restore power to the load
System fault o r Fault has ruled out
2) To charging failure handling method
a) Solar energy to battery charging, if there is no correct configuration solar panels of power or exceed rated
charging current, voltage, will appear charge fault, the checking and debugging, press the button,
recoverability work.k
Charge fault Fault has ruled out
3) Solar panels fault and processing:
a) 24 hours in the case of sun light, the controller is not charging, the solar energy is not connected or not connected
correctly, check the solar panel to the connecting cable of the controller is open, troubleshooting, recoverability
work.
No solar charge Are charging
