Panel Description:
Item Name Descriptions
1 POE : PoE power input indicator: the LED lights when the PoE input jack (the
lower jack) has 36V~57V input. (802.3af/at)
2 SOL : Solar power input indicator: the LED lights when SOL terminal is
connecting to a solar panel and the solar panel input voltage is over 12V.
3 CHA : Charging indicator: the LED lights when BAT terminal is connected to
battery and charging
4 LOA :
Loading indicator: the LED lights when the rear panel output terminal is
connecting to a device and offering power.
The LED always on when power ready.
5 REV : Battery polarity reverse indicator: the LED lights when the battery
polarities are reversed. (detail description see Sec. 5.1)
6 IN : PoE Input Jack: the lower RJ45 jack, used for PoE input. Allowed input
voltage 36~57V
7 OUT : PoE Output Jack: the upper RJ45 jack, used for PoE output; Output
voltage depends on what model you selected.
8 FUSE Fuse: for output over current protection, limiting the battery output current
<= 20A.
9 SOL : Solar Panel Terminal: used to connect the solar panel.
10 BAT : Battery terminal: used to connect the battery.
11 LOA : Load Terminal: for wire size 12~16AWG, the output voltage is the same
as battery voltage.

Operation Guide
1. Connect the battery to the BAT terminal. Make sure the polarities are
correctly connected. Sequentially connect the solar panel to SOL terminal
and connect POE source to PoE input (lower) jack.
2. Make sure the battery is properly connected to the unit. If no battery is
connected, then the voltage at BAT terminal will no voltage.
3. The solar panel cannot be used stand alone without battery connected.
4. When a solar panel and PoE input are connected to the charger, if the
voltage of solar panel is higher than 15V, then solar panel is always the
main power source of the charger.
5. When charge from solar panel, as the battery full and turn to floating
stage, the CHA light will start flash.
6. When charge from PoE, as the battery full, the CHA light will be turn off, if
the CHA is always flash, that means the input wattage lower than the
required minimum wattage. If only charge battery, the minimum input
wattage is 30W, if full load, the minimum input wattage is 80W.
7. When battery connect to BAT terminal and with valid voltage, then the
LOA indicator will always light on even no load connected.
8. LOA It can be two parallel outputs on the rear panel, make sure the total
draw is not over the limit.

9. The V- of PoE input, Solar input, and battery(-) are not the same
grounding, must be properly isolated.

4. Protection:
4.1 Battery Polarity Reverse Protection:
If only battery connected to terminal, when the battery polarities
were reversed, the model will stop output and REV indicator light on.
When the battery be removed and re-connected to terminal, the
function will be enable,.

4.2 Battery Over Discharge Protection:
Cuts off the load when the battery voltage is lower than 11V + 0.3V,
and auto recover when the battery voltage returns to 12 V + 0.3V
4.3 Battery Over Charge Protection:
Fuse control, over 20A, the fuse will be burnt.
4.4 Solar Panel Polarity Reverse Protection:
When solar panel polarities be reversed, the charger stop output, it
won’t damage the charger or end device
4.5 Solar Panel Over Charge Protection:
When charge current over 20A, the fuse will be burnt.
4.6 Output Short Circuit Protection:
When the rear output terminal or PoE output be short circuit,
protection be active, the product stop output and auto-recover when
the terminal back to normal connection.
4.7 Battery Output Current Limit:
The fuse will be burnt when battery output current over 20A
4.8 Load Output Voltage Limit:
The output voltage of the rear terminal is the same as battery.
4.9 Battery Charge Voltage : (POE Input)
E/Q = 14.5V ± 0.1V
F/L = 13.5V ± 0.2V

User’s Manual SOL20P12LFP-56B1N
When the charger is in charging mode and charge current is more than
1.8A. charge voltage for battery is 14.5V ± 0.1V
when charge current is lower than 1.67A . charge voltage for battery is
13.5V ± 0.2V.
4.10 Battery Charger Voltage : (Solar input)
harge Voltage = 14.7 V ± 0.2V
(when use solar as the power source, it is not a continuous source, the
charge voltage should be higher, to shorten the charge time.)
