Panel Description

input jack (thelower jack) has 36V~57V input.
2| | 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.

** 7| **| PoE Output Jack: the upper RJ45 jack, used for PoE output; Outputvoltage depends on what model you selected.
** 8| | Fuse: for output over current protection, limiting the battery output current<= 10A.
9| | Solar Panel Terminal: used to connect the solar panel.
**** 10| ****| Battery terminal: used to connect the battery. NOTE: ALWAYS CONNECT THIS TERMINAL FIRST. If solar panel or PoE source is installed before the battery, and if the polarities of battery are reversed, then the fuse will be burnt.
11| | Load Terminal: for wire size up to 12AWG, the output voltage is the sameas 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. (If solar panel or PoEsource is installed before the battery, and if the polarities of the battery be reversed, then the fuse will be burnt.)
2. Make sure the battery is properly connected to the unit. If no battery is connected, then no output at BAT terminal.
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 floatingstage, 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. It can be two separate 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.

Electrical specifications

B. POE: fixed current, 2.0A ma

4. Battery Types: 1 2V AGM Battery

5. Protection
   Battery Polarity Reverse Protection
   If only battery connected to terminal, when the battery polaritie were reversed, the model will stop output and REV indicator lighton. When the battery be removed and re-connected to terminal,the function will be disable, if there is a PoE power sources beconnected, when the battery polarities reversed, the battery will be disconnected.
   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
   Battery Over Charge Protection: Fuse control, over 15A, the fuse will be burnt.
   Solar Panel Polarity Reverse Protection: When solar panel polarities be reversed, the charger stop output, it won’t damage the charger or end device
   Solar Panel Over Charge Protection: When charge current over 15A, the fuse will be burnt.
   Output Short Circuit Protection: When the rear output terminal or PoE output be short circuit, protection be active, the product stop output and auto-recoverwhen the terminal back to normal connection.
   Battery Output Current Limit: The fuse will be burnt when battery output current over 15A
   Load Output Voltage Limit: The output voltage of the rear terminal is the same as battery.
   POE Charge Voltage :
   Float = 13.4V ± 0.2V Equalize
   = 14.2V ± 0.2V
   SOLAR Charge Voltage :
   Charge Voltage = 14.4 V ± 0.2V
