Running state
01
The grid
priority
mode
(Default)
Under working mode 01, grid power bypasses the
inverter to the load while also charging the battery.
When the grid is over-voltage, low-voltage or has
serious distortion,the unit will transfer to battery
power supply. When the grid power is back to
normal, the unit will transfer back
to grid power bypassing.
03
Battery
priority
mode
Under working mode 03, grid power is not charging the
battery. The unit can be charged via Solar charger only
as Solar and battery are the main power sources. Solar
charge the batteries and supply the power to the loads
through the inverter. When the battery is discharged to
the low-voltage protection threshold, the unit will transfer
to gridpower bypassing (if grid power is available).
When the battery is fully charged, the unit will transfer
back to battery power supply.

-14-
When you want to use the unit as an uninterrupted backup power to your
loads, you are suggested to wire theAC input with terminals. Use the correct
size of AC power cable (2.5mm² or bigger), make sure the AC power voltage
is in the range of unit allowance. Turn on “⑧-AC input breaker” and battery
breaker THEN wire AC power source to the “⑫-AC input terminals” .
VERY IMPORTANT NOTE:
DO NOT connect “④-AC Input Socket” and “⑫-AC input terminals” at
same time! It may cause the short circuit and damage the unit.

4.6 Outputs
4.6.1 AC outputs
The AC loads are connected to the “②/⑬-- AC Output” outlets on the front
panel. The total AC loads power should be no more than the inverter rated
power.

4.6.2 DC outputs
The 5VDC loads are connected to the “①- 5VDC Output”(USB souckets)
on the front panel. The total 5VDC USB output current is 2A.
The 12VDC loads is connected to the “③- 12VDC Output” on the front panel.
The total 12VDC output current is 2A.
Make sure the positive (+) and negative (-) of the DC loads are wiring
correctly before plug in. DC output short circuit may cause the unit damage.

5.1 Inverter Power ON/RUN
5.1.1 Battery starting
Turn on the battery breaker, press and hold the "ON / OFF" button on the
operation panel for 2 seconds, release it after the buzzer beeps. The "INV"
indicator light lights, turn on the A/C out breaker.
5.1.2 AC Input Power-on
Connect AC input (Utility or Generator), the "LINE" indicator light turns on,
turn on the A/C input breaker.
5.2 Solar Charge Controller
Make sure the solar power voltage and wattage are in range of unit design.
Wire solar panels to the “Solar Input Terminals”, turn on the “Solar Input
Breaker”. When the solar panels are exposed to sunlight, the "PV" indicator
light on. The solar power is charging the batteries through the MPPT solar
charge controller.

5.3 Shutdown
Shutdown: Turn off the loads, disconnect themains input, and then press the
"power on / off button" for 2 seconds, release after the internal relay action,
the unit AC output is off, LCD screen turned off, turn off all the breakers;

OPERATION PRECAUTIONS: To start the unit, do it according to the
following steps: Turn on the battery circuit breaker, then turn on the
solar input breaker. To shut down the unit, turn off the solar input
breaker, then turn off the battery breaker
Caution: If the unit is idle for long time, please turn off the battery
breaker to avoid the battery deep discharging unless the solar power
or AC charger is connected to maintain the battery.

6 Maintenance
6.1 This series of product requires little maintenance, battery only needs
to maintain its charge for full life expectancy.
6.2 If you do not use the equipment for a long period of time, it is
recommended it be charged every 4-6 months. Under normal
circumstances,the battery’s life will be 3-5 years, if found in poor condition,
you must replace the battery early. Replacement of the battery must be
carried out by qualified personnel. Battery should not be individually
replaced; the overall replacement should follow the battery supplier's
instructions.
6.3 In moderate climates every 4 to 6 months the battery must be discharged
to shut down and recharged to full capacity. In high temperature regions the
battery discharge and charge should be done every 2 months.
6.4 Before replacing the battery, turn off the device and disconnect it from
the main and close the batteryswitch.Remove allmetal objects such as rings
and watches. Use insulated handles and screwdrivers, do not put tools or
other metal objects on the battery pack.
6.5 When connecting the battery cable, it is normal for small sparks to
appear which will not cause any harm to equipment or the personal safety
andthe operator. Do not cross connect the battery terminals.
