2Installation Explanation
Installation
Get ready the related tools& cables. We suggest you choose the appropriate cables
2
to ensure the current density 4A/mm and this is good for reducing cable voltage
22
drop. Recommendation30A using 10mm cable50A using 16 mm cable.
Check whether installation
place accordswith the relative
safety rules.Pleaseavoid installing
and using thecontroller under
the following conditions:wet,
dusty places or places with
ammable and explosive gases.
Install the controller at the
vertical plane. Please refer to
chapter 5for more detailedinfo
about thespacing between the
installing holes. In order tomake
the controller havegood thermal
dissipation, pleasespare10cm
above & below the controller.
As shown as the right gure, connect the loads, battery and solar panels with the
controller in order. Pay attention to connect the loads, batteryand solar panels right.
Plug the external thermal sensor into the interface of the thermal-sensoron the left
of the controller.
Disassemble:To avoid the accident, please dismantle the solar panels, battery, loads
from the controller in order.
Attention:Connecting the battery reversed will not damage the controller, but will
cause safety risk on yourloads.

After the controller electries right, it will enter into the displayinginterface of
battery voltage. This interface is the main interface of thecontroller. P ress
buttonto go through the interfaces of the following parameters. Ifthe interface
can be reset, press button for long( 5 seconds, and the number on the
interface starts to icker), then it enters into the settinginterface of this parameter.
After nishing setting, press buttonfor long to exit the setting interface, and the
number stops ickering.

this voltage, the controller will disconnect the load loop to
prevent the battery from over-discharging.

Breakdown & disposal
If the screen shows as the right it means thebattery
voltage is lower than the protection voltage. The controller
enters into the low voltage protection state and the load loop
disconnects. Use the solar panels or charger to charge for the
battery. When battery voltage recovers to the protection
voltage, the controller will recover to supply power for load,
and enter into the working state.
Low voltage protection & disposal:

If the screen shows as the right and thelight it
mean the current of the load loop is 1.2 times fothe rated current
within 3 seconds, and the controller is at overloading state.After
removing some loads, the controller will supply power to the
loads automatically within seconds, or you can press button to recover the
power supply compulsively.
Overloading protection & disposal:
If the screen shows as the right and thelight it
meanstherehappensshort-circuitintheloadloop,andthecontroller
is at short-circuit protection state. Please check whetherthe loads
are damaged and whether the connecting cables are short-circuit.
After eliminating the breakdown, press button to recover the power supply
for the loads.
Short-circuit protection & disposal:
Breakdown & disposal of solar panels:
Sign means the controller do notdetect the existence of solar panels.
Please check whether the connecting with the solar panels is nigood condition, and
check whether the cables connecting the solar panels and the controller are i n
open-circuit condition.
If when you turn onthe load, it means the starting impulsion current is
more than twice of the rated working current. Please restart the controllerfor times.
Other exceptional conditions: Please contact the distributor or manufacturer.
