protection

2. Installation Explanation

Prepare the related tools and cables. Renogy suggests you choose the

appropriate cables to ensure the current density < 4 A/mm2, which is good for

reducing cable voltage drop. Recommendation: 30A using AWG 8 cable, or 50A

using AWG 6 cable.

1. Check whether the place of installation accords with the relative safety

rules. Please avoid installing and using the controller under the following

conditions: wet places, dusty places, or places with flammable and

explosive gases.

2. Install the controller at the vertical plane. Please refer to chapter 5 for

more detailed information about the required spacing between installing

holes. In order for the controller to have good thermal dissipation, please

spare 10cm above and below the controller.

3. As shown in the figure to the right, connect the loads, battery, and solar

panels with the controller in proper order. Pay close attention when

connecting the loads, battery, and solar panels, to ensure the job is done

correctly.

4. Plug the external thermal sensor into the interface of the thermal sensor

on the left side of the controller.

Disassemble: To avoid a dangerous accident, please dismantle the solar

panels, battery, and loads from the controller in the proper order.

Attention: Connecting the battery in a reversed manner will not damage the

controller, but will create a safety risk on your loads

Parameter Review and Setting

After the controller properly electrifies, it will enter the battery voltage onto the

displaying interface. This interface is the main interface of the controller. Press

button to go through the interfaces of the following parameters. If the interface

can be reset, press button for at least 5 seconds (>5 seconds, and the

number on the interface starts to flicker), then it will enter into the setting

interface of this parameter. After finishing the setting, press button for over 5

seconds to exit the setting interface, and the number will cease flickering.

3.1 Battery Voltage Review

As shown in the figure to the right, the displayed

number is the present battery voltage. This

interface is the main interface, and it shows the

charging and discharging state, battery capacity,

and battery voltage.

3.2 Load ON/OFF Controlling

At the battery voltage review interface, you can

press button to turn the load on or off;

however, this button does not have the same

function at other interfaces.

3.3 Environmental Temperature Review

This review should be used for the temperature

compensation when the battery ceases

charging. As shown in the figure to the right, the

displayed number on the interface is the

surrounding environmental temperature of the

controller.

3.4 Review Generating Current of Solar Panels

As shown in the figure to the right, the displayed

number is the input current from the solar

panels.

3.5 The Load Current Review

LOAD

OFF

As shown in the figure to the right, the displayed

number is the load current.

3.6 Reviewing and Clearing Accumulative, Generated Ah of Solar Panels

As shown in the figure to the right, the displayed

number is that of the accumulative, generating

AH of the solar panels. At this interface, press

for over 5 seconds (>5 seconds), and it will

clear the accumulative, generating AH.

3.7 Reviewing and Clearing Load Accumulative, Discharging AH

As shown in the figure to the right, the displayed

number is that of the accumulative, discharging

AH of the loads. At this interface, press for

over 5 seconds (>5 seconds), and it will clear

the accumulative, discharging AH.

3.8 Reviewing and Setting Low Voltage Protection Function

As shown in the figure to the right, the displayed

number is the protection voltage. If the battery

voltage is lower than the protection voltage, the

controller will disconnect the load loop to prevent

the battery from over-discharging. At this

interface, press for over 5 seconds (>5

seconds). The number will start to flicker, which

means the controller enters into the interface of

setting the protection voltage. Use buttons

and to adjust this parameter. After finishing

this set-up, press for over 5 seconds (>5

seconds) to exit the interface and the controller

can store this setting number.

3.9 Reviewing and Setting Recovering Voltage for Voltage Condition

As shown in the figure to the right, the displayed

number is the recovery number. After the

controller enters into a low voltage protection

state, and when the battery voltage recovers

to be higher than the recovering voltage, the

controller will reconnect the load loop

automatically. At this interface, press for over

5 seconds (>5 seconds). The number will start

to flicker, which means the controller enters into

the interface of setting the recovery voltage. Use

buttons and to adjust this parameter.

After finishing this set-up, press for over 5

seconds (>5 seconds) to exit this interface and

the controller can store this setting number.

3.10 Reviewing and Setting the Voltage Where Controller Ceases Charging

As shown in the figure to the right, the displayed number is the voltage where the

charger will cease charging. When the battery voltage reaches this voltage, the

controller will disconnect the charging loop to prevent the battery from

overcharging. After the battery voltage drops, the controller will reconnect the

charging loop. At this interface, press for greater than 5 seconds (>5

seconds). The number will start to flicker, which means the controller enters into

the interface to set the voltage where the controller ceases charging. Use buttons

and to adjust this parameter. After finishing this set-up, press for

greater than 5 seconds (>5 seconds) to exit this interface and the controller can

store this setting number.

3.10 Reviewing and Setting the Load Mode

Shown in the figure to the right is the reviewing

surface of the load mode.

•24h – Indicates normal mode. Loads are

under the condition of supplying power

without breakdown.

•1h-23h – Indicates delayed mode of light

control. Load starts to supply power after

dark and sun down after working for the

delayed setting hours.

•0h – Indicates Light Control. Load starts

to supply power after dark and stops after

dawn.

At this interface, press for greater than 5

seconds (>5 seconds). The number will start to

flicker, which means the controller enters into

the interface to set the load modes. Use buttons

and to adjust this parameter. After

finishing this set-up, press for greater than 5

seconds (>5 seconds) to exit this interface and

the controller can store this setting number.

Breakdown And Disposal

Low Voltage Protection and Disposal

If the screen displays the information as shown

in the figure to the right, it means the battery

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 alternate charger to charge

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.

Overloading Protection and Disposal

If the screen displays the image shown in the

figure to the right, and the light flickers, it mean

the current of the load loop is 1.2 times that of

the rated current within 3 seconds, and the

controller is at an overloading state. After

removing some loads, the controller will supply

power to the loads automatically within seconds,

or you can press to recover the power

supply compulsively.

Short-Circuit Protection and Disposal

If the screen displays the image shown in the

figure to the right, and the light flickers, it means

there is a short-circuit in the load loop, and the

controller is in a short-circuit protection state.

Please check whether the loads are damaged

and whether the connecting cables are short-

circuited. After eliminating the breakdown, press

to recover the power supply for the loads.

Breakdown and Disposal of Solar Panels

Sign flickering means the controller does not detect the existence of solar

panels. Please check whether the connection with the solar panels is in good

condition, and check whether the cables connecting the solar panels and the

controller are in open-circuit condition.

Load Impulsion Breakdown

If flickers when you turn on the load, it means the starting impulsion current

is more than twice that of the rated working current. Please restart the controller

four times. Other exceptional conditions: Please contact the distributor or

manufacturer.
