• LCD Display - The LCD display provides details on battery
level and power drain. The drain is measured in amps A (or
milliamps mA).The system will limit the current to about 10A.
• Load Switches - The three main functions, AC, DC and the
LED light have individual On/Off switches.When this switch is
moved to the UP position, the load is enabled and will turn
on based on the position of the STBY Switch.
• Menu Push Button - Is used to navigate through the menus
on the LCD display. This switch as two modes. A TAP is a
short push, and HOLD means to hold the button in.
• STBY Switch - This is the master switch to turn on the unit.
When this switch is down, the unit is in standby and the
loads will not be on. If the load switches are on, they will be
displayed on the LCD as *AC, *DC, *LED. When this switch is
in the UP or ON position, any load that has it's switch on the
UP (ON position) will be turned on. In this case the LCD will
show +AC, +DC, +LED
• Reset - A toothpick or similar nonmetal object can be used to
reset the internal computer chip without turning the unit off.
• DC Output - This standard "cigarette lighter style" outlet
provides 12VDC output at 5A.The center conductor is
positive.
• Battery - This switch will disconnect the batteries. If the unit
is to be stored, turning this switch to the OFF position will
remove all power drain from the batteries for the longest
storage life. It is not necessary to turn the unit off under
normal circumstances between uses. This switch should be
turned off whenever the unit is opened up to change the
batteries.
• AC Output - This connector provides 120VAC at 120 watts. If
150 watts is exceed or the batteries become low, the system
will automatically switch the AC off.
• AC Input - You can use the supplied line cord to plug the unit
into a household outlet to recharge the battery. AC voltage
should be in the range of 100~240VAC. This connection is
also fused with a 2A fuse for safety.

AVIGATING
When the unit is powered on the LCD screen
shows the HOME PAGE. After a brief period it
automatically transitions to a screen with the
product model number and software version number. These
pages can be skipped by pushing the menu button on each
page.
After another delay the MAIN screen that
consists of a status area (showing "SBY"
here), three indicators and the battery Auto
charge bar. The status bar tells you whether
the unit is in "ON" ,"SBY" (standby) or AUTO
mode, and cycles through which outputs are activated. These
outputs are AC, DC and LED (for the LED light). Preceding each
is "*" for in standby, a "+" for on and a "!" for an error. This
area will flash showing the system is properly running.
• "ɸ" or "-" : The first indicator shows if an automatic mode is
on.
• or : The next shows if the unit is receiving power from
the solar panel or if it is plugged in.
• or or : The third indicator shows if the unit is
charging. An empty battery means the battery is low. A half
battery means it is charging. A full battery means the
charging is complete. A "?" means there is a charging error.
While the battery has a full charge, the status indicator may
switch between the half and full battery as the unit does a
maintenance charge.
The charge bar at the bottom of the screen gives an indication
of how much charge remains in the battery.
The system LOADs may be used while the unit is charging, but,
the output power is still limited to the available battery energy
and the charging power from either the solar panels or AC line
cord.
To navigate through the menus on the LCD display use the
MENU button which has two modes: One TAP is a short push.
HOLD means to hold the button in. If the screen is dark, the
first push of the button will wake the screen up.
From the main screen, a MENU button HOLD
will transition the display to the battery
information screen. It initially displays the
batteries' voltage.
A TAP will alternate between the voltage and
the current displays.
A HOLD press on the battery information screen will move to
the programmable options screen.
While on the GoBACK screen a HOLD will exit
the program mode back to the battery level
screen. A TAP will go to the next page. Now,
pressing hold will put the program option in brackets ([]). Once
the brackets are on, a TAP will increment the option. A button
HOLD will remove the brackets and TAP to move onto the next
option. You must navigate to the [GoBACK] page and HOLD to
return to the information pages.
The screen will automatically reset to the information page if no
presses are made for a few seconds.
There are two programmable MODES to
select from, AUTOon will turn the system
from SBY to ON when the solar panel no
longer receives sufficient sunlight (adjustable in later settings)
and go back to standby after the specified duration (adjustable
in later settings). If the system is already ON, it will go to SBY
after the specified duration.
SLEEP mode may also be selected, which will automatically turn
the loads off after the specified duration has expired.
Notes:
1. In these automatic modes, the STBY/ON switch may not
represent the current state as shown on the LED and LCD
display.
2. If a mode is set, a "ɸ" will be shown in the AUTO area of the
LCD display.
3. While active, the status area will show AUTO,
4. The hour timer used is only approximate.
To adjust the amount of time the unit is ON in
either automatic mode, navigate to the
DURATION page, press HOLD to remove the
brackets and set the ON time [1 to 12 hours]. HOLD again to
save and navigate to exit.
For the AUTO on mode, the light level can be
manually set in the same way as the
DURATION. Navigate to the SP page. The
value of the light on the panel is displayed for reference. The
value may be set from 1 to 16, the default is 4. There is a 5
minute delay once the SP threshold is meet to allow for the sun
to set.
The OTG 15W is also capable of send and SOS signal by
flashing the high brightness 3 watt LED on the side on the case.
This signal will be sent about 3 times a minute and will last
