3. INSTALLATION
3.1 Inspecting the packing carton for damage that may have occurred while in transit. Immediately
notify the carrier and place of purchase if any damage is found. Retain the package for future use.
3.2 Connect the AC power only to a grounded shockproof wiring system to avoid electric shocks
resulted from current leakage. Keep wire length as short as possible to minimize voltage loss.
The installation must be performed by qualified personnel.
Recommended AC wire size:
Capacity \ Input voltage 220/230/240Vac
SP8000 AVR AWG10
3.3 Connecting the DC input power cord with the correct battery voltage and correct polarity, the
inverter must be as close as possible to the battery to avoid the voltage drop on the power cord.
WARNING: Incorrect polarity may blow fuse and cause internal damage of inverter.
Recommended Battery wire size:
Capacity Max Current/DC Voltage Wire Size
SP8000 AVR 150A / 48Vdc AWG 6 * 2pcs
3.4 Connecting your equipment to the Inverter. To ensure your home appliances to be powered &
protected during a utility failure, it is important to make sure that the maximum power needed by the
equipment is not over the rated capacity of the Inverter. the “Over load” symbol will show up, and
alarm will beep if the load is over the rated value (the default setting is 100%), and wait for one
minute to shutdown when load remains between 100% ~150%. Meantime, if the overload is severe
(the default setting is 150%), the Inverter will shut down in two seconds for protecting itself.

3.5 Connecting Solar input: Make sure the open circuit voltage of the PV array is less than the DC
maximum input voltage of the built-in solar charger. The suggested PV voltage ranges are shown
below:
SP8000 AVR：48 ~ 90Vdc (the range is also for VOC of the solar panel)

4. OPERATION
4.1 Once it’s connected with normal city power, the inverter will charge the battery automatically,
when inverter is off, the battery symbol and battery level will blink every second during charging.
If AC auto turn-on function is enabled, the inverter will turn on automatically when city power is
normal. If auto turn-on is disabled, please push the button for about one second on the front
panel; then the inverter will give power to the outlets after a short-time of beeping.
4.2 Pushing the button 4 seconds for ‘OFF mode’, the CPU will turn off the power from the AVR
or inverter. But, the output relay will transfer to bypass mode automatically. To cut off the
auto-bypass power from utility, please turn off the auto-bypass switch. In off mode, inverter will
keep charging if city power is normal.
4.3 DC Start: During a blackout, push the button one second for entering “OFF” mode (showing
“OFF”); then push again for one second, and the inverter will be turned on and enter into backup
mode. To turn off the power from SP8000 AVR; please push the button for 4 seconds; then LCD
display will show “OFF”; then, wait for 10 seconds, and SP8000 AVR will turn off the power
automatically.
4.4 Operation block diagram is shown blow. The auto-bypass switch is available.
4.5 DC Priority Mode/Inverter Mode: There are 2 main operation modes when AC utility is normal,
the DC priority mode and theAC priority mode. To set DIPSW3 up will enable DC priority mode. In this
mode, DC power will be priority and system will draw power from battery when battery voltage is
normal. System will automatically switch toAC mode and keep the battery at basic charging level (48V)
when battery voltage is low. In the DC priority mode, solar charger or fan generator will be the main
charger power. The system will not transfer to inverter mode until battery voltage is charged to 13V for
each 12V battery.

11
4.6 DC Priority Mode/Green Mode: When load level is low (under 35W), the inverter efficiency is very
low. To save the battery energy, user can enable the green mode (set DIP SW4 up). The system will
transfer O/P relay to bypass mode at low load level. Please turn on the auto-bypass switch at rear
panel under green mode, or the output voltage will become zero when system transfers to bypass
mode.

12
4.7 Green mode level setting (by the set-up software, UPS wizard; or through LCD display):
When green mode function is enabled, the inverter will turn off the power within 60 seconds in the
battery mode with the power consumption lower than the pre-set level (adjustable by using the
UPS wizard software). The default value of green mode setting is zero (disabled).
4.8 AC Priority Mode/AC Mode: AC Priority Mode/AC Mode: To set DIP SW3 down will enable
AC priority mode. In this mode, the AC O/P power is mainly from AC utility input with AVR
(auto-voltage-regulation). The battery charging voltage comes from AC input and converted by
the bi-direction inverter to support battery charging power. If the solar charger or fan generator is
sufficient, the solar charger will also provide charging power to battery.
4.9 Battery charging mode(From AC): The inverter provides two charging modes for the battery,
quick charging and trickle charging. The quick charging provides higher charging current when
battery is empty and reduces the charging current when battery voltage increases. Trickle charging
will begin automatically after battery is 90% fully charged.
4.10 When a blackout happens, the buzzer will emit two beeps every 8 seconds for alarm during
the first minute of blackout. You can disable the alarm by a short push at the main control button,
and to push it again will enable the alarm, the setting can be shown on LCD display. When battery
voltage is too low or too high, the inverter will emit alarm, if the under voltage or over voltage is too
much, the inverter will turn off itself automatically.
Note: The main control button provides test function at normal mode, but will become with alarm-reset
function at battery mode.

13
4.11 There are two ways to change the setting of inverter. The 1
st
way is to use the UPS Wizard
software, please contact your service people for detailed information. The 2
nd
way is to make it
through the LCD display, by the following procedures:
4.11.1 To push the two selection buttons, △and ▽, at the same time for 3 seconds until the LCD
display begins to blink.
4.11.2 To change the inverter O/P frequency at DC start
When the frequency value is blinking, push any selection button, △or ▽, for 1 second to change
the frequency setting! The setting will keep changing every 2 seconds if you keep pushing the
button. Push two selection buttons at the same time for next setting, or leave the LCD blinking
without pushing any button for 30 seconds to end the setting.
4.11.3 To change the inverter rated voltage
When the voltage value is blinking, push any selection button for 1 second to change the rated
voltage. Keep pushing the button until the required voltage blinking. Then, push two selection
buttons at the same time for next setting; or leave the LCD blinking for 30 seconds to end the
setting.
4.11.4 To change the Auto-turn-on setting at the recovery of utility power
The method of changing the setting is similar to that of voltage setting. If you don’t need
Auto-turn-on function, please select “oFF”. To select “On” is for immediate auto turning on at the
recovery of utility power. While the “On.S” means auto turning on with safety mode. Sometimes,
when battery is empty after blackout, the auto turn-on function will have very short backup time if
blackout happened again following with a short time recovery. To select “On.S” will provide
Auto-turn-on only when the battery is charged for, at least, 30% of its capacity.

14
4.11.5 To change the green mode level at battery mode
When the “Gn.0” is blinking, it means the green mode level if off. The inverter will not turn off the
power automatically if there’s no any load connected to inverter. When the “Gn.1” is blinking, it
means that the green mode level is 1% of full load. The inverter will turn off power automatically
if blackout happened when load level is less than 1% of full load.
Push the selection button “△“ for 2 seconds at least, to increase the green mode level or push
“▽“ to decrease the level. Push two selection buttons at the same time to end the setting .
