2: Installation Instructions
Installation
1 Ready Qi installation tools and materials, and cable.
Please matching suitable cable
2 Ensure that the current density <4A/mm2 this will help to
reduce the line pressure drop.
Recommended: 30A current 10mm2 60A current
20mm2 80A current 25 mm2 cable. Check whether the
installation site
Comply with the relevant safety requirements, avoid
damp, dusty, there is easy
Inflammable, explosive and corrosive gases place to
install using the controller
3 Install 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
4 As shown on the right wiring sequence: load, battery, solarQ
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
5 Before 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
6 Warning: 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 undervoltage protection voltage, the controller has entered
undervoltage
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
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 or 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.

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
