2. SAFTY INSTRUCTION
2.1 Transporting
1. Disconnect all power cables if necessary.
2. Be careful not to damage the Solar Inverter while transporting.
3. Don‘t move the Solar Inverter upside down.
4. Please transport the Solar Inverter system only in the original packaging (to
protect against shock and impact).
2.2 Positioning
1. Do not put the Solar Inverter on rugged or declined surface.
2. Do not install the Solar Inverter system near water or in damp
environments.
3. Do not install the Solar Inverter system where it would be exposed to direct
sunlight or near heat.
4. Do not block off ventilation openings in the Solar Inverter system’s housing
and don’t leave objects on the top of the Solar Inverter.
5. Keep the Solar Inverter far away from heat emitting sources.
6. Do not expose it to corrosive gas.
7. Ambient temperature : 0℃- 40℃
2.3 Installation
1. Connect the Solar Inverter system only to an earthed shockproof socket
outlet.
2. Place cables in such a way that no one can step on or trip over them.

4
2.4 Operation
1. Do not disconnect the mains cable on the Solar Inverter system or the
building wiring socket outlet during operations since this would cancel the
protective earthing of the Solar Inverter system and of all connected loads.
2. The Solar Inverter has its own internal power source (batteries). The output
terminals may be live even when the Solar Inverter is not connected to the
AC supply.
3. Ensure that no fluids or other foreign objects can enter the Solar Inverter
system.
2.5 Maintenance and Service
1. Caution - risk of electric shock.
Even after the unit is disconnected from the mains power supply (building
wiring socket outlet), components inside the Solar Inverter system are still
connected to the battery and are still electrically live and dangerous. Before
carrying out any kind of servicing and/or maintenance, disconnect the
batteries and verify that no current is present.
2. Batteries may cause electric shock and have a high short-circuit current.
Please take the precautionary measures specified below and any other
measures necessary when working with batteries:
- remove wristwatches, rings and other metal objects
- use only tools with insulated grips and handles.
5
3. CABLE CONNECTION
3.1 Inspection
1. The system may be installed and wired only by qualified electricians in
accordance with applicable safety regulations.
2. When installing the electrical wiring, please note the nominal amperage of
your incoming feeder.
3. Inspect the packaging carton and its contents for damage. Please inform
the transport agency immediately should you find signs of damage.
Please keep the packaging in a safe place for future use.
4. Please ensure that the incoming feeder is isolated and secured to prevent
it from being switched back on again.
3.2 Connection
1. Solar Inverter Input Connection
If the Solar Inverter is connected via the power cord, please use a proper
socket with protection against electric current, and pay attention to the
capacity of the socket.
2. Solar Inverter Output Connection
The output of this model is with socket-types only (NEMAor IEC). Simply
plug the load power cord to the output sockets to complete connection.

5. Solar Inverter OPERATION
5.1 Check Prior to Start Up
1. Ensure the Solar Inverter is in a suitable positioning.
2. Check input cord is secured.
3. Make sure the load is disconnected or in the “OFF” position.
4. Check if input voltage meets the Solar Inverter rating required.
5.2 Storage Instruction
Disconnect input power in rear panel if you will not use it for long period. If the
Solar Inverter is stored over 3 months, please keep supplying power to the
Solar Inverter for at least 24 hours to ensure battery fully recharged.
5.3 Operation Procedure for LCD Model
Please follow the instructions below for Solar Inverter operation.
1. Once the AC source is connected, the
LCD Display shall light up immediately
to display first the main menu of
greeting context and the Normal LED is
blinking to indicate ready to switch on
the inverter.
2. By pressing the Enter-key and the Down-key simultaneously for 3 seconds,
the Solar Inverter will start up after two beeps and Normal LED lights up to
indicate the power is from its inverter to the load.
3. When the Down-key and the Up-key are pressed simultaneously for 3
seconds, the inverter will be turned off after two beeps and the Solar
Inverter is on the standby status (LCD display illuminates and Normal LED
is blinking) until AC source is disconnected.

7. OPERATION MODES OF THE SOLAR INVERTER
7.1 Solar Inverter System Block Diagram
7.2 Normal Operation
There are two main loops whenAC utility is normal: the AC loop and the
battery charging loop. The AC output power comes from AC utility input and
passes through static switch to support power to load. The battery charging
voltage comes fromAC utility input and converted byAC/DC charger to
support battery-charging power.

20
7.3 AC Utility Failure (Battery Mode)
The AC output comes from battery, passing through DC/AC inverter and
static switch within the battery backup time.
