4.4 Battery Type

 Operating Steps

Under Battery Voltage interface, press SET button and hold on 5s then enter into the

interface of Battery type setting. After choosing the battery type by pressing MENU

button, waiting for 5s or pressing SET button again to modify successfully.

 Battery Type

①Sealed (Default) ②Gel ③Flooded

NOTE: Please refer to the battery voltage parameters table for the different

battery type.

5. Protections

 PV Short Circuit

When PV short circuit occurs, the controller will stop charging. Clear it to resume normal

operation.

 PV Reverse Polarity

Fully protection against PV reverse polarity, correct the wire connection to resume

normal operation.

 Battery Reverse Polarity

Fully protection against battery reverse polarity, correct the wire connection to resume

normal operation.

Warning：

Shock Hazard!

When the battery is reverse, the load will appear the equal and reverse

polarity voltage to battery.

 Battery Over Voltage

When the battery voltage reaches to the set point of Over Voltage Disconnect Voltage,

the controller will stop charging the battery to protect the battery from being over

charged to break down.

 Battery Over Discharge

When the battery voltage reaches to the set point of Low Voltage Disconnect Voltage,

the controller will stop discharging the battery to protect the battery from being over

discharged.

 Battery Overheating

The controller detect the battery temperature through the external temperature sensor. If

the battery temperature exceeds 65ºC, the controller will automatically start the

overheating protection to

stop working and recover below 50 ºC.

 Load Overload

Load will be switched off when 1.05 times rated current overload happens. Controller

will automatically attempt to reconnect load for 5 times. If overload protection still exist

after controller’s 5 times attempts, user have to reduce load appliance, then press the

SET button or repower the controller or wait for one night-day cycle (night time>3

hours).

 Load Short Circuit

Load will be switched off when load short circuit (≥4 times rated current) happens.

Controller will automatically attempt to reconnect load for 5 times. If short circuit

protection still exist after controller’s 5 times attempts, user have to clear short

circuit ,then press the SET button or disconnect and restart the controller or wait for one

night-day cycle (night time>3 hours).

 Damaged Remote Tempera

ture Sensor

If the temperature sensor is short-circuited or damaged, the controller will be charging or

discharging at the default temperature 25℃ to prevent the battery damaged from

overcharging or over discharged.

 Controller Overheating

If the temperature of the controller heat sinks exceeds 85℃, the controller will

automatically start the overheating protection and recover below 75℃.

 High Voltage Transients

PV is protected against small high voltage surge. In lightning prone areas, additional

external suppression is recommended.

6. Troubleshooting

Faults

Possible reasons

Troubleshooting

The LCD is off

during daytime when

sunshine falls on PV

modules properly

PV array

disconnection

Confirm that PV wire connections

are correct and tight

Wire connection is

correct, LCD not

display

1. Battery voltage is

lower than 9V

2. PV voltage is less

than battery voltage

1. Please check the voltage of

battery. At least 9V voltage to

activate the controller

2. Check the PV input voltage

which should be higher than

battery’s

Interface

blink

Battery over voltage

Check if the battery voltage is

higher than OVD point (over

voltage disconnect voltage), and

disconnect the PV.

Interface

Battery

over discharged

When the battery voltage is

restored to or above LVR point

(low voltage reconnect voltage),

the load will recover

Interface

Battery Overheating

The controller will automatically

turn the system off. But while the

temperature decline to be below

50 ºC, the controller will resume.
