Eco-Worthy 20A/30A PWM LCD Display Solar Charge Controller Manual

Battery type

• B01=General lead-acid(default)
• B02=3S X 3.7V 11.1V lithium ion Battery
• B03=4S X 3.2V 12.8V LiFePO4 Battery
• B04=AGM / B05=GEL / B06=Flooded

Advise: choose B01 if you don't know your lead-acid battery type.
B01-B03 has 2-stage charging process.
B04-B06 has multi-stage charging process.

Setting: hold left key until number flash, click【+/-】to adjust, and hold left key again until number stop flashing, the setting is saved.

Load output timer control

【24H】-output turn on all the time.
【0H】-output turn on only during Dusk to Dawn(D2D).
【1~23H】-output turn on after sunset and turn off after

1~23H. Attn: no matter which is selected, output will turn off when battery is in a LVD condition.

Setting method: same as above one.

Charge voltage setting (only for B01,B02,B03)

Different battery types have different maximum charging voltage. Consult your battery supplier for more information. Default setting is recommended.

The setting is the same as above.

Low voltage re-connect(LVR) setting

When a low voltage disconnect happens, the controller will wait until the voltage raise more then this voltage, then it will re-connect the load again.

Default setting is recommended. The setting is the same as above.

Low voltage disconnect (LVD)setting.

When battery voltage is lower than this voltage, the controller will cut off the output automatically.

Default setting is recommended. The setting is the same as above.

D2D trigger value(solar panel voltage)

When the work mode is D2D or Timer, the controller will detect the solar panel voltage to decide whether its day or night, so to decide to enable load output or not.the higher this value is, the earlier it enables the load output.

Default setting is recommended. The setting is the same as above.

D2D trigger delay value(Second)

When the controller detect the solar panel voltage is lower than trigger value, it will delay for 10S and detect again to make sure night falls, then enable the load output.some car light or thunder lighting will confuse the controller and make it think its daytime, using this delay can prevent interference.

Default setting is recommended. The setting is the same as above.

Short-circuit protection setting (only for some model).

Some inductive or capacitive consumer will trigger the short-circuit protection during start up. Therefore, you can disable the SC-protection manually.

SC.F=OFF, SC.n=ON. The default is ON.

Default setting is recommended. The setting is the same as above.

PWM charging enable (only for B01,B02,B03)

PWM could generate noise and interference which will trigger a high voltage protection in a Li-Battery BMS system. Therefore, to avoid this happen, you can choose to disable the PWM charging. The controller will charge the battery until Setting voltage (Menu NO.3), then it will fully stop charging, when battery voltage drop, it will re-charge again.

P.oN=PWM ON. P.oF=PWM OFF.

Default setting is P.oN. The setting is the same as above.

Output mode control.

Normally a LED light connected to the output terminal will work only after sunset, therefore, LC1 can be selected. But some load equipment requires to work only after sunrise, for example, a camera or a pump.therefore, you can choose LC2. LC1 and LC2 are logically opposite on D2D control.

If you have set a timer (1-23H) control, for example 16H, but in reality the night /day is only 12Hour. LC1/2 means output work only 12H(any sunset or sunrise will stop the countdown), but LC3/LC4 will work 16H (ignore any sunset or sunrise and countdown until setting hours)

Default setting is LC1. The setting is the same as above.

Battery low voltage warning.

To prevent damage of the battery, Output automatic disconnect when battery voltage drop below LVD voltage and automatic re-connect if raise above LVR voltage.

Press button to ignore for one time and force to work again

Battery high voltage warning.

To prevent damage of the load equipment, Output automatic disconnect when battery voltage raise above HVD voltage and automatic re-connect if drop below HVR voltage.

Press button to ignore for one time and force to work again.

Output over current warning (only for some model).

Load current exceed rated current. If it does not resume within 60 seconds, it will turn into E04 warning.

Press button to ignore for one time and force to work again.

Output short-circuit warning (only for some model).

Output automatic disable when there is a short-circuit and will resume after 10 seconds.

Press button to ignore for one time and force to work again.

High temperature warning.

When the temperature of the controller exceeds 80℃, it will enter stand-by mode and stop charging or discharging until the temperature falls to 70℃.

Press button to ignore for one time and force to work again.

PV over-voltage warning.

In order to protect the internal circuit, Charging automatic stop when PV voltage exceed 50V and automatic recover when voltage drop below 45V.(for 12V/24V system)
