ABOUT YOUR PV SYSTEM

MODEL TYPE

Your Solahart PV System is designed for the polycrystalline photovoltaic modules to be roof and/or stand

mounted with the inverter installed in a serviceable position and connected to the electrical distribution grid

(often referred to as ‘the grid’) as per AS 4777.1. These instructions together with the installation instructions

supplied with the inverter give limitations on positioning of the inverter.

This Owner’s Guide and Installation Instructions applies to the following PV modules:

HSL60P6-P -1-250 (250 W module) REC255PE (255 W module)

Note: Unless approved otherwise by Solahart, only modules of the same make and model may be used in

Solahart PV systems.

SYSTEM OPERATION

The Solahart PV System is comprised of two main components; a string or array of photovoltaic modules

and an inverter.

The photovoltaic (PV) modules transform solar radiation into electrical energy in the form of direct current

(DC). In order to utilise this energy and feed it back into the grid, the direct current is transformed into

alternating current (AC) by the inverter. This conversion is also known as DC to AC inversion.

The alternating current generated by the inverter is fed into the main switchboard, which in turn is connected

to the grid.

Note: For safety reasons, the inverter will only operate when the mains electrical supply is available from the

grid. Your Solahart PV System cannot provide a backup electricity supply to your home appliances if the

mains supply is interrupted.

If the energy generated by the PV System is not sufficient to meet domestic demands, the energy necessary

to ensure the standard operation of the connected devices is drawn from the grid.

If the energy generated exceeds that required by property demands, your electrical network operator may

allow the difference to be directly injected into the grid and become available to other users. Energy injected

into the grid can be measured by electricity network operators as either gross (everything generated) or net

(excess generated). Injected energy may or may not be purchased by the local electrical network operator

according to national and local standards, and regulations.

SYSTEM OVERVIEW

• A photovoltaic module is composed of many photovoltaic cells assembled on the same frame.

• A string is composed of a certain number of modules electrically connected in series.

• An array is composed of one or more strings connected in parallel.

• The inverter converts direct current produced by the array into alternating current.

• The PV Array DC Isolators provide a means for isolating the array.

• The Inverter AC Isolator provides overcurrent protection of the inverter and a method of isolating the PV

System from the electrical distribution grid.

Warning: For the inverter to be effectively electrically isolated, both the PV Array DC Isolator(s) and the

Inverter AC Isolator(s) must be in the OFF position.

OPERATING PROCEDURES

TO TURN PV SYSTEM ON

1. Turn on the PV Array DC Isolator(s) at the inverter.

2. Then turn on the Inverter AC Isolator at the inverter (if installed) and the Solar Supply Main Switch at the

AC switchboard.

TO TURN PV SYSTEM OFF

1. Turn off the Solar Supply Main Switch at the AC switchboard and the Inverter AC Isolator at the inverter

(if installed).

2. Then turn off the PV Array DC Isolator(s) at the inverter.

Warning: Depending upon the system there may be more than one PV Array DC Isolator.

Warning: To effectively isolate the wiring between the AC isolator and switchboard, the Solar Supply

Main Switch located in the switchboard must also be in the off position.

Warning: PV array DC isolators do not de-energise the PV array and array cabling.

ACTIONS TO UNDERTAKE IN THE EVENT OF AN EARTH FAULT ALARM

1. Limit access to all parts of the PV system

2. Contact Solahart Service on 1800 638 011 or your nearest Solahart dealer.

ELECTRICAL SAFETY

SAFETY REQUIREMENTS

The voltages and currents produced by a single module or modules connected in series (voltages are added

together) or in parallel (currents are added together) can be dangerous.

Note: Only qualified personnel should perform work on photovoltaic systems.

UNIQUE HAZARDS OF DC ELECTRICITY

PV modules generate DC electricity as soon as they are exposed to sunlight. Once the current is flowing,

breaking or opening a connection (e.g. disconnecting a DC cable from the inverter) can cause a DC

electrical arc. Unlike arcs occurring in conventional low voltage AC wiring, DC arcs are not self-extinguishing.

They are a potentially lethal burn and fire hazard, capable of creating high temperatures that can destroy

contacts and connectors.

EARTH FAULTS

An earth fault is a system fault where a short circuit is formed between the DC circuitry of the PV system and

earth. As the PV system owner, please be aware of the current method of communication of earth faults on

your system. Refer to Earth Fault Alarms on page 44 for details.

PERIODIC MAINTENANCE

GENERAL

Due to the safety concerns involved with working at heights and working with electricity, we recommend the

householder follow the maintenance schedule provided below. Other maintenance should be performed by a

suitably qualified person, such as a CEC accredited installer. ustralian Standard S/NZS 5033 provides a

recommended maintenance schedule for PV systems.

Modules supplied by Solahart have been designed for easy maintenance. Normal rainfall should naturally

clean the modules. The need for cleaning will vary with the location of the installation, amount of rainfall,

pollution and inclination of the modules.

RECOMMENDED MAINTENANCE SCHEDULE

Maintenance Action Frequency Remarks

Under daylight conditions check that your

inverter is operating correctly (refer to the

Inverter Manufacturer’s manual for

details).

Weekly If not operating correctly, contact your

Solahart dealer.

If you have a communications device

installed, such as the SM Webconnect or

BB Wi-Fi logger card, log in to your

inverter manufacturer’s web portal and

check that your system is operating, data

has been logged and communication has

been maintained.

Monthly If you are unable to log in or your system is

not operating correctly, contact your Solahart

dealer.

Visual inspection of PV system

components from ground level, to check

for:

Quarterly

• ccumulation of debris around

components.

Gently remove debris from components that

are safely accessible from ground level.

• Shading of the array. Trim trees, if required.

• Visible damage to any components. Contact your Solahart dealer.

• Cleanliness of PV modules. To optimize electrical output, it is

recommended that the modules are cleaned

when dirt can be seen on the glass surface.

Please contact your Solahart dealer to

arrange module cleaning.

If you have a communications device

installed, such as the SM Webconnect or

BB Wi-Fi logger card, log in to your

inverter manufacturer’s web portal and

ensure that the contact details of the PV

system owner or responsible officer are up

to date to ensure that inverter fault

notifications are delivered.

Quarterly If you are unable to log in, contact your

Solahart dealer.

Contact a suitably qualified person, such

as a CEC accredited installer, to inspect

the system.

Yearly This inspection can be arranged through your

Solahart dealer, and should ensure that:

• Inverter’s ventilation filters and fans are

cleaned.

• ll fastenings are tight, secure and free

PERIODIC MAINTENANCE

of corrosion.

• ll cable connections are tight, secure

and free of corrosion.

• Cables are not damaged in any way.

• Earthing of the modules and module rails

is satisfactory.

• Electrical characteristics are within

specification.

• The C and DC isolator/circuit breakers

function correctly.
