Important Safety Information

Warning - Risk of Electric Shock

Failure to comply with these warnings and instructions can result in

damage to property, risk of fire, serious injury or death.

Do not remove the covers. The unit contains no user serviceable parts.

Hazardous voltage is present inside the unit from both DC and AC sources.

Hazardous voltage remains inside the unit even when disconnected.

The photovoltaic (PV) array supplies hazardous voltage when exposed to

light, even at very low intensity. Even ungrounded photovoltaic arrays

present an electric shock hazard through ground capacitance.

The unit is designed to supply power to the electric grid (AC utility) only. It

must not be connected to other AC electric generators or power supplies.

This may cause permanent damage to the unit and/or AC power supply.

The earth connection of the electric grid (AC utility) to the inverter should be

firm and visible.

Connection to the electric grid (AC utility) typically requires a permit or

interconnection agreement with the electricity provider. Contact your

electricity provider for more information.

All local and national codes and regulations for installation, wiring and

inspection of electrical equipment must be complied with.

Installation and troubleshooting of this unit must only be performed by

properly trained electricians or installation technicians, qualified to install or

service PV inverters.

Incorrect installation, troubleshooting by unqualified persons or modification

of the electrical wiring poses a safety risk to the installers, home/facility

occupiers and other users/operators of the electric grid (AC utility).

Both AC and DC voltage sources are terminated inside this equipment. The

unit must not be opened until both AC and DC circuits have been individually

disconnected for at least 3 hours. (Due to risk of electric shock from energy

stored in capacitors.)

Please take out the unit from the packaging box carefully. Check if there is

any obvious damage. Do not install the unit, if it is damaged. Please contact

your local dealer for a replacement.

The SPH inverter is the latest transformer less design. Please check the

requirements for your country regarding earthing regulations.

2. PV installation system diagram

PV array: Provides DC power to the SPH inverter. A DC

Disconnect Switch or optional Solar Concentrator is usually

fitted between the PV array and the SPH inverter.

SPH inverter: Converts DC power from the PV array into AC power. The AC

(Alternating Current) power is supplied to the electric grid (AC

utility). The SPH inverter uses Maximum Peak Power Tracking

(MPPT) to optimize the PV array operation and deliver

maximum power to the electric grid.

Connection: The “interface” between the SPH inverter and the

System Grid usually consists of an electrical breaker or fuse and

terminals for connection. It may also contain a disconnect

switch. For proper safety, this part must be designed by a

qualified electrician or electrical installation technician.

Utility: The electricity supply from the main electric grid

system must be single phase 220V to 250V, 50Hz

or 60Hz.

3. Installation

Before starting installation please check the following items:

This unit is suitable for indoor and outdoor usage. For best performance and

service life, outdoor installations should be sheltered from direct exposure to

rain and water.

The unit can operate with an ambient temperature of -25C to +55C. For

best performance and service life, the unit should be operated with an

ambient temperature of 0C to +40C. Above this temperature, the power

output may be reduced. It is recommended to shade the unit from direct

exposure to sunlight to prevent increased operating temperature.

The electric grid must be 220V to 250V, 50Hz or 60Hz single-phase.

Connection to electric grid must be approved by the electricity provider.

The installation must be done by a certified electrician.

The unit must be installed vertically in the orientation shown.

Step1: Mount SPH inverter to the wall or other vertical

surface

1. Select a solid wall or vertical surface to mount the unit. The mounting

surface must have sufficient strength to carry the weight of the unit (Given

in the specification). In areas of seismic activity, additional support or

restraint may be necessary. It is recommended that the inverter is installed

at a height that provides comfortable viewing and operation of the display

and controls.

2. There must be at least 25cm clear space above and below the unit. This is

to allow for proper air circulation and convection cooling.

3. Mark the 4 mounting hole positions required using the mounting backplate

as a template.

4. Select appropriate mounting hardware for the type of mounting surface and

drill mounting holes of the appropriate size.

5. Fix the mounting backplate to the mounting surface using the selected

hardware at each of the 4 mounting holes.

6. Fix four screws with spacer on the four corners of the mounting back plate.

7. Hang the inverter unit onto the mounting back plate and press down.
