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.
