Product Description Using the accessories
The SPSS450 combines highly efficient Solar panels, a solar charger, a power inverter and a Lithium
Polymer battery in to a robust, waterproof case creating an easy-to-use, 'plug and play' back-up
system.
Open the 1/0 access door by setting the door locks to the "OPEN" position. It is
recommended that the unit be placed horizontally as shown in
Figure 1.
This system is specifically designed for mobile off-grid applications, where space and weight
limitations are abundant. The SPSS450 portable solar system is the perfect system for
emergencies providing up to 532 Watt-hours of energy. The built-in solar charge controller allows
the expansion of an additional 18 V solar panel (Max. 70 W).

The DC output can now be used. Please limit the current load for each DC output. Please
do not overload the output as doing so may damage the unit. Please turn OFF the DC
output when not in use. Figure 7 shows the maximum current per DC output.
The AC output can now be used. The maximum load it can handle is
350 Watts.
Please do not overload the output as doing so may damage the unit. Please turn
OFF
the AC output
when not in use. Inverters have small idle power consumption, leaving
the switch ON will drain the battery over time.

The AC and DC outputs can be ON at the same time. When the Main switch is ON, press
the AC output switch and then the DC output switch (or vice versa) to turn both outputs on.
When both outputs are turned ON, the LCD display will light blue, and "DC OUT" and "AC
OUT" along with the light bulb icon will be shown.

Charging Charging with additional solar panels
To speed up the charging time, an 18V solar panel can be used at the DC input terminal
Charging via Solar
If not planning on using the unit while charging with solar, make sure that the Main
switch is in the OFF position.
with a maximum of input of 70 Watts.
Find a sunny, dry location that is free from overhanging tree branches, obstructions or
shading. Unclip the two latches on the side of the unit and open the top cover
completely as shown in Figure 9.
Figure 9. Charging via solar panels
When charging with the built-in SOW solar modules, it will take about
17 hours
to fully
recharge the internal battery.

If planning on using the unit while charging with solar, make sure that the Main switch is
in the ON position. Then turn ON the desired output.
AC and DC outputs
can also be
used while the unit is being charged by solar. However, limit the current output to the
values mentioned earlier.
Charging via AC
When charging via AC 2-pin inlet, make sure that the Main Switch is in the
OFF
position.
It is recommended that when charging via AC input do not use the AC and DC output
terminals.
Connect the 2-pin inlet AC cable that is included with the unit. The unit can be charged
in vertical or horizontal position. Figure 11 shows the unit being charged
horizontally
with the AC cable.
Figure 11. Charging via AC power cable
It will take about
3 hours
to fully recharge the internal battery. Do not cover or block the
exhaust vents when charging with the AC cable. The unit can be
left plugged in
once
the battery is fully charged. This will maintain the battery when the unit is not in
operation.
State of Charge
When charging with the solar panel(s) or with AC power, the display will turn on, and
after a few seconds, the backlight will turn off.
Figure 12 . Digital display charging motion
The display will show a "charging motion” when charging via solar panel(s) or AC power.
The state of charge is shown by percentage, and by the battery icon. Each bar in the battery
icon represents about 20% of charge. Once the battery is fully charged, the "charging
motion" will stop, and the state of charge will remain at 100%.

Troubleshooting
AC output load exceeded the maximum rating of the inverter:
If the AC output load exceed the maximum power rating of 350 Watts, the internal
inverter will shut off to avoid damaging the unit. When this happens, the digital display will
show a flashing "ERROR" message with a sad face light bulb icon as shown in Figure 13.
The "AC OUT" text will flash as well.
DC output load exceeded the maximum current rating:
If the DC outputs exceed the maximum current rating shown in Table 4, the DC output will
shut off to avoid damaging the unit. When this happens, the digital display will show a
flashing "ERROR" message with a sad face light bulb icon as shown in Figure 14. The
"DC OUT" text will flash as well.
Figure 14. AC output error message
Figure 13. AC output error message
To clear the message, disconnect all of the load(s) and press the AC output switch to turn
the inverter on to restore power.
Once the AC output button is pressed, the message should be gone and the system
should be back to normal.
To clear the message, disconnect all of the load(s) and press the AC output switch to turn
the inverter on to restore power.
DC Output Switch
Once the DC output button is pressed, the message should be gone and the system
should be back to normal.
AC output load exceeded the maximum rating while DC output is on (or vice versa):
If one of the outputs overloads while the other is in operation, the digital display will only
flash the "ERROR" message and flash the output that has encountered the issue. Please
correct the issue as described above.
Unit will not power on:
If the unit will not power on, try to flip the Main switch
ON
and
OFF
a couple times to
check if there is a connection issue. If the unit still will not power on please call Dosun
Electronics Co., Ltd Support to find a possible resolution.

Unit not charging with the built-in solar panels:
If the unit is not detecting the solar panels, make sure that the unit is not shaded or that
the unit is not being blocked from sunlight. If the unit is exposed to full sunlight and still will
not charge via solar please call Dosun Electronics Co., Ltd Technical Support to find
a possible resolution.
Unit not charging with external solar panel:
Please make sure that the DC power plug is in the right socket, and that is making
proper connection. Make sure that the solar panel is not shaded or that is not being
blocked from sunlight. If none of the above fixes the problem, please call Dosun
Electronics Co., Ltd Technical Support to find a possible resolution.
Unit not charging via AC power cord
Please make sure that the AC power plug is making proper connection. Make sure that
both end plugs are all the way in. If none of above fixes the problem, please call Dosun
Electronics Co., Ltd Technical Support to find a possible resolution.
Do's and Don'ts
Do's:
•
Clean the built-in solar panels when dirty with window cleaner or with a wet cloth.
•
Store the unit in a dry place free from moisture, heat, and water.
•
Ensure the solar panels are exposed to sufficient light – ideally, position them
to face the sun directly.
Don'ts:
•
Store or place the unit near fire or places that can achieve higher temperatures.
Doing so may cause damage to the unit internals, and or battery explosion.
• Submerge the unit under water. Although the unit is not waterproof, it is water
resistant as long as the accessory door is closed.
•
Leave the unit outside when raining.
•
Overload the AC or DC outputs. Follow the power and current ratings mentioned
earlier in this manual.
Warnings
•
Keep the unit away from small children. Allow only adults to use the unit.
•
Do not dismantle or modify the system. Doing so, can result in damage to the unit
and or onto yourself. Any modifications that will alter the device will void the
warranty.
• In case of a hazard or emergency, turn OFF the unit immediately.
