4. CHARGING PRINCIPLE

Three-stage Method

Charging is performed according to the battery charging characteristics using three-stage method.

a) The first stage is named as „constant current‟: a): Trickle Charge: when the battery terminal

voltage is relatively low, then the charging current is low likewise which can prevent the battery

temperature is too high. b): Quick Charge: When the battery terminal voltage is relatively high,

the charging current will rise to rated value. Large current charging operation leads

to an increase in the electricity quantity of the battery.

b) The second stage is named as Absorption Charge: after the first stage, the battery voltage is rise

to absorption charge value rapidly, and the charger voltage will keep constant. The battery

terminal voltage will stabilize in the absorption charge value with the decreasing of charging

current.

c) The third stage is named as Float Charge: After the above two stage, the charge is basically

completed and the Float Charge is started automatically. In this stage, the charger voltage

reduces to float voltage and the charger current reduces to float value. After that charging current

will only neutralize the battery self-discharge. Even long-term charging cannot harm the battery,

as charger can keep the battery fully charged and so guarantee long lifetime of the battery.

voltage is relatively low, then the charging current is low likewise which can prevent the battery

temperature is too high. b): Quick Charge: When the battery terminal voltage is relatively high,

the charging current will rise to rated value. Large current charging operation leads

to an increase in the electricity quantity of the battery.

b) The second stage is named as Float Charge: The charging current will decrease with the rising

of battery electricity. As soon as charging current value falls below 0.3A, the battery is basically

fully charged. After that charging current will only neutralize the battery self-discharge. Even

long-term charging cannot harm the battery, as charger can keep the battery fully charged and

so guarantee long lifetime of the battery.

Output Port

Normally closed, internal normally closed port connect with B-;

It is output when charger cannot charge the battery after 60s

delay expired (charge failure output); if battery under volt warning

enabled, it is output only when detect battery under volt warning

alarms.

Solar Indicator

Indicator lights up if solar cell panel correctly connect and solar

voltage exceeds 6V. If load over current, battery indicator and

solar indicator flash per 0.5s.

Battery Indicator

Indicator lights up if battery correctly connect to the battery and

battery voltage exceeds 3V;

If fail to charge, battery indicator flashes per 0.5s;

If load over current, battery indicator and solar indicator flash per

0.5s.

NOTE 1: During gen-set is running, high charging current will cause voltage drop in charging line, so

recommend separately connecting to battery terminal to avoid disturbance on sampling precision.

NOTE 2: Power connection order: connecting battery firstly and then solar panel; Power disconnection

order: disconnecting solar panel firstly, and then battery. Please follow the correct sequence to

connect/disconnect power and inhibit to operate energized connection cable in case of damaging the battery.

8. APPLICATION

APPLICATION INSTRUCTION:

Solar Choose 18V or 36V solar panel, please reference solar type as below.

Battery Choose 12V or 24V battery (24V battery cannot be charged while using 18V

solar panel).

Load Used for controlling lighting lamps to provide lighting in the dark, and also

available for other functional load.

Display Connecting monitoring device to portA and portB of RS485 to display the

charging status data.

Mains Charger Mains charger can be backup power supply for the battery, if battery volt is too

low caused by the solar cells fault, heavy load, and long-term un-sufficient energy. It is avoiding

the battery to over discharge. Internal of output port is normally closed point of relay, and another

end of normally closed point is connecting with B-, which connect when low battery volt occurs.
