ECO-WORTHY EW1907-30A 12V24V 30A Solar Charge Controller

SAFETY INSTRUCTIONS

Make sure your battery has enough voltage for the controller to recognize the battery type before first installation.
The battery cable should be as short as possible to minimize transmission loss.
This controller is suitable for 12 / 24 V maintenance free lead-acid battery, gel battery and lithium iron phosphate battery. Please select the corresponding battery type in the setting menu.
The charge controller is only suitable for regulating solar modules. Never connect other DC or AC charging source to the charge controller

PRODUCT FEATURES

Build-in industrial grade micro controller.
Large LCD display, all adjustable parameter.
PWM charge management.
Build-in short-circuit protection,open-circuit protection, diode reverse current protection,overload protection, low temperature production.
Lithium battery activation

SYSTEM CONNECTION

Connect the battery to the charge controller
Connect the solar module to the controller
Connect the DC loads to the charge controller (optional)

Reverse sequence order when uninstalling! An improper sequence order could damage the controller!

KEY FUNCTIONS

Function 1 : when the battery voltage is normal, double-click the button to turn on or turn off the load.
Function 2 : when the battery voltage is normal, click the button to view the current and temperature.
Function 3 : press and hold the key for 2s to enter the menu. On the menu that needs to change the setting, press and hold the key for 2s to make the number flash, then click to adjust the setting value, and then press and hold the key for 2s to stop the number from flashing.
Function 4: long press the key for more than 10s until F01 is displayed on the screen to restart the controller.
Function 5 : press and hold the key for more than 20s until F02 is displayed on the screen to restore the factory settings.

FAQ

Q:why doesn’t the controller showing charging when I connect the solar panels?
A:Check if all the connections are correct and tight, and there is no revers current occurred. If everything is correct, check if the panels are clean and not covered by anything. If everything are in fine condition, check if panels are connected to the right voltage as the pre-set voltage of the controller (MENU1). If everything is normal but still not charging, use a multimeter to test every panel to see if there’s a defective one.
Q:why is my charging current so low?
A:Incorrect PV voltage or any shading on the solar panels may cause low PV output current. Or it may caused by the PWM charging mode that would decrease the charging current when the battery type is “b01” or “b03” and the voltage has risen to the pre-set voltage.(MENU3)
Q:why is my load off unintentionally?
A:Check MENU7, MENU9 and MENU10 to see what mode have you set controller to. For example, if you set MENU7 to 【00H】, then the controller would cut-off DC output then the sun is set and there’s no more PV input. If all the settings are normal but your load is still off, you should check if you load or wire is defective.
Q:the power generation is not enough to supply my load, what should i do?
A:In this case, it’s suggested to add additional solar panels and battery to expand the generation and capacity of your system. Or you could just lessen your loads to slow down the power consumption.
Q:why does my battery runs out of power so quickly right after it’s fully charged?
A:It could be because the power of your load is way higher than the capacity of your battery. In this case, add more batteries or lessen your loads. Or test your battery to see if it’s dying due to long-time usage. You can test it this way: discharge your battery to nearly empty, then charge it with PV or AC input. If the battery voltage rises rapidly and drops rapidly when you disconnect the charge, then your battery may be dying and you should replace it.
