Bioenno Power SC-122420JUD CC/CV Series User Manual
CC/CV SOLAR CHARGE CONTROLLER FOR LFP
THIS CONTROLLER IS FOR USE WITH LITHIUM IRON PHOSPHATE BATTERIES ONLY
OVERVIEW
Thank you for choosing the Bioenno Power SC-122420JUD Series CC/CV Solar Charge Controller. Your
product comes in 20A Maximum Load Current and is designed to be used with Lithium Iron Phosphate
(also commonly known as LiFePO4 or LFP) batteries only. The controller uses our proprietary CC/CV
Constant Current/ Constant Voltage circuitry to ensure maximum compatibility and performance with
the Bioenno Power battery. Your Solar Charge Controller comes equipped with an LCD display with a
visual presentation of usage status for your solar system and additionally features our smart technology
chipset which allows your Solar Charge Controller to automatically function at the correct mode of
operation as well as the ability to manually adjust between different modes of operation and load
power delivery.

DISPLAY
Your LCD display will come with the following icons:
The Main Display Menu should display a combination of one or more of the following icons upon startup
of your Solar Charge Controller Unit:
DIGITAL DISPLAY
SOLAR PANEL
CHARGE INDICATOR
BATTERY
LOAD INDICATOR
LOAD
HOUR
VOLTAGE
These are the icons you should
expect to see and engage with under
Bioenno Power recommended usage
conditions. These icons reflect the
state of function of your Solar Panel
and your Battery.
YOUR LOAD SHOULD BE CONNECTED
TO YOUR BATTERY AND NOT TO THE
SOLAR CHARGE CONTROLLER
DIRECTLY.
While you can safely attach your load
to the load port, we do not
recommend using the load port to
support your device(s). Always
connect your load directly to the
battery. You generally can ignore this
icon.

SPECIFICATIONS

Dimensions: 6.5 in. x 3.46 in. x 1.5 in. (166 mm x 88 mm x 38 mm)
Weight: 0.59 lbs. (0.27 kg)
*Note: This solar charge controller can accept any voltage under 50V but it will not boost the voltage if the panel voltage is less
than the battery voltage. Make sure your panel voltage is higher than your battery voltage for optimum performance.
OPERATION PROCEDURE ORDER
1) Make sure the total rated current of the Solar Panel Array and Load are less than the rated
current of your Solar Charge Controller –in this case your maximum current is 20A
2) Make sure the polarity of the wiring from your Solar Panel Array, Battery and Load are
correctly matched to prevent the risk of a short circuit which may damage unprotected
devices
3) Mount you Solar Charge Controller to your selected surface and fasten it securely using
screws
4) Check whether the Battery voltage and Solar Panel Array voltage is within the requested
range
5) Loosen the screw terminals on your Solar Charge Controller –there are 6 screw terminals
total from left to right in this order: Solar Panel Positive, Solar Panel Negative, Battery
Positive, Battery Negative, Load Positive and Load Negative
6) Connect the Battery’s input to your Solar Controller using the two screw terminals in the
middle marked with the Battery pictogram, you may need an adapter –attach the wiring
securely but do not over-torque your Solar Charge Controller’s terminals
7) Connect your Load to your Battery’s output using the Battery as the buffer between the
Solar Panel Array and the Load (we DO NOT recommend using the Load Terminals for most
uses) –attach the wiring securely but do not over-torque your Solar Charge Controller’s
terminals
8) Connect the Solar Panel Array to the Solar Panel Input on your Solar Charge Controller using
the two screw terminals on the left marked with the Solar Panel pictogram –attach the
wiring securely but do not over-torque your Solar Charge Controller’s terminals
9) Your Solar Charge Controller should assume standard operation herein

*Note: In the event of a short circuit, your Solar Charge Controller trip an auto-reset fuse –disconnect load immediately, let it
stand for 10-20 minutes, the internal fuse will automatically reset during this period. Before resuming operation, confirm your
load does not exceed the 20A Maximum Load Current of your Solar Charge Controller.

SC-122420JUD CONTROLLER ADDENDUM
This is an addendum to the user manual. By default the SC-122420JUD is set to charge LiFePO4
batteries. To charge other battery chemistries, do the following:
1) Press the Menu (left red) button until “b00”shows on the display
2) Hold down the Menu (left red button) for 5 seconds, until the “b00”setting starts to flash.
3) Push the Select (right red button) until “b01, b02, b03”shows up corresponding the following
b00 = LiFePO4
b01 = Flooded Lead Acid
b02 = AGM (Absorbed Glass Mat)
b03 = Gel
b04 = LiFePO4
b00 is the same as b04 settings
