ATTENTION!
Loads like motors or products employing motors, and copy machines or
products employing heater lamps, may damage your SP inverter. Always
consult with your load device manufacturer for the value of the inrush
current the device draws at startup, so as to make sure it does not exceed
the SP inverters capability to handle such inrush currents. Refer to SP
inverter's specifications for the crest factor value as a measure of its
ability to handle the inrush current of its load.

ⅢINSTALLATION
3-1 Safety
3-1-1 Positioning
1. Do not put the Solar SP on rugged or declined surface.
2. Do not install the Solar SP system near water or in damp environments.
3. Do not install the Solar SP system where it will be exposed to direct sunlight or
heat.
4. Do not block ventilation openings in the Solar SP system’s housing and don’t
leave objects on top of the Solar SP.
5. Keep the Solar SP far away from heat emitting sources.
6. Do not expose it to corrosive gas.
7. Ambient temperature: 0℃- 40℃
8. Do not position the Solar SP upside down.
9. Do not position the Solar SP where debris such as dust, easily accumulate.
10. The Solar SP should be positioned indoors where people can not touch
it accidentally because of potential skin burns caused from high operating
temperatures.
11. The Solar SP requires at least 30 cm of clearance in between the top and the
bottom for heat dissipation.
3-1-2 Transporting
1. Disconnect all power cables if necessary.
2. Be careful not to damage the Solar SP while transporting.
3. Don‘t move the Solar SP upside down.
4. Please transport the Solar SP system only in the original packaging (to protect
against shock and impact).

13
3-1-3 Installation
1. Connect the Solar SP system only to a grounded shockproof wiring
system to avoid electric shocks resulting from current leakage.
2. Place cables in such a way that no one can step on or trip over them.
3. Keep wire lengths between the array and the Solar SP as short as possible to
minimize copper losses.
4. The installation must be done by qualified personnel.
3-1-4 Operation
1. Do not disconnect the main cable on the Solar SP system or the building
wiring socket outlet during operation. This would cancel the protective grounding
of the Solar SP system and of all connected loads.
2. The Solar SP has its own internal power source (batteries). The output terminals
may be live even when the Solar SP is not connected to the AC supply.
3. Ensure that no fluids or other foreign objects enter the Solar SP system.
4. Disconnect input power in rear panel if you will not use it for long period. If the
Solar SP is stored over 3 months, please supply power to the Solar SP for at least 24
hours to ensure battery fully recharged.
3-1-5 Maintenance and Service
1. Caution - risk of electric shock.
Even after the unit is disconnected from the main power supply (building wiring
socket outlet), components inside the Solar SP 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.

14
3-2 Mounting
1. Make sure a wall surface or a solid place can support theSolar SP.
2. Mark the bracket hole positions of the Solar SP on the wall.
Hole Diameter
SP1200~SP3600
SP5000~SP8000
Upper Hole
9.5mm
15mm
Lower Hole
7mm
10mm
3. Use a screw driver to fix the Solar SP.
4. If more holes are required to be drilled on the bracket, make sure no metal shavings
are left inside the Solar SP. It could result in a short circuit when the Solar SP is
operating.

3-3 Wiring
3-3-1 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.
3-3-2 Connection
1. Grounding
-AC and DC Grounding: The Solar SP has to be connected to a grounded
permanent wiring system; and the array has to be grounded as well.AC and DC
are separately grounded.

3. DC Input Terminals
- Array (Input):
* Make sure the open circuit voltage (Voc) of the PV array is less
than the DC maximum charge voltage (See 6-1 Specification) and the short
circuit current (Isc) is less than DC maximum charge current (50A).
Recommend DC wire size:

8.0KVA
5.5mm2(10AWG)
* Make sure the electric polarity is correct when connecting DC
terminals. Incorrect electric polar connection will damage the Solar SP!
* Whenever a PV array is exposed to sunlight, it converts sunlight
into electric power and results in shock hazard at its output wires and
terminals. To avoid the risk of shock, cover the array with an opaque
material before any wiring connections.
- Solar Connector (Input Media)
* Solar connector is affixed 2 cables with Tyco terminals compatible with
output terminals of a module’s junction box.

ⅣOPERATION
4-1 Prior to Startup
1. Ensure the Solar SP is in a suitable position.
2. Check that input cord is secured.
3. Make sure the load is disconnected or in the “OFF” position.
4. Check if input voltage meets the Solar SP rating required.
5. Get batteries and AC cables connected before starting the Solar SP.
4-2 Storage Instruction
Disconnect input power in rear panel if you will not use it for long period. If the
INVERTER is stored over 3 months, please keep supplying power to the
INVERTER for at least 24 hours to ensure battery fully recharged.
4-3 Operations Procedures for LCD Model
Please follow the instructions below for INVERTER operation.
1. Once the AC source is connected, the
LCD Display shall light up immediately
(8~10 seconds in main menu of greeting
context) to standby for Solar SP startup.
2. By pressing the Enter-key and the Down-key simultaneously for 3 seconds, the
Solar SP will start up after two beeps and Normal LED lights up to indicate the power
is from its bypass AC main to the load.
3. When the Down-key and the Up-key are pressed simultaneously for 3 seconds, the
Solar SP will be turned off after two beeps. The Solar SP is on standby status (LCD
illuminates and Normal LED is blinking) untilAC source is disconnected.
