• The property has a single-phase power supply.
• The system can be installed within the same calendar year as the date of sale.
• The inverter is located within 5 metres of the main switchboard.
• Clear and safe access is available to the property and roof area.
• Roof pitch is assumed to be 25 degrees.
• There is sufficient space within the existing switchboard or sub-board to accommodate all required solar and monitoring equipment.
• Existing electrical wiring and switchboards comply with current Australian Standards, including Ergon Energy (QECCM) requirements for new meter installations.
• The roof structure and condition (including roof sheeting and fixings/screws) are suitable for solar installation and do not require rectification works.
• A stable and reliable 2.4 GHz Wi-Fi connection is available at the inverter location for system monitoring.
• Ceiling spaces are accessible and suitable for the installation of DC and AC solar cabling where required.
• The building does not contain asbestos or asbestos-containing materials.

Battery Installation Assumptions

All circuits required to provide backup power during a grid outage are protected by Type A RCDs.

Battery Location & Installation Requirements

• The battery must not be exposed to direct sunlight.
• The battery must be installed a minimum of 600 mm from any building entry or exit.
• The battery must be located within 5 metres of the new or existing inverter.
• The battery must be mounted on a non-combustible surface, including both wall and floor.
• The battery must be installed at least 600 mm from any unrelated equipment (e.g. air conditioners, hot water systems).
• The battery must be a minimum of 600 mm from any window opening into a habitable room (e.g. bedrooms, kitchens, living areas).

Controlled Tariffs (T31 & T33)

Unless otherwise advised prior to installation, all appliances currently connected to Ergon Energy controlled tariffs (T31 & T33) — including hot water systems, pools, and air conditioners — will be rewired to Tariff 11. This ensures maximum benefit from your solar and battery system. Where specific timing or load control is required, installation of timers is recommended.

Ergon Energy – Solar Connection Fees & Charges

Please note that Ergon Energy connection fees are not included in this quotation or proposal. Any applicable charges are billed directly by Ergon Energy to the electricity account holder.

Standard Connection

In most cases, no Ergon Energy fees apply for a standard fixed-export or zero-export connection. If further assessment is required, an assessment fee of $120 may apply.

Dynamic Connection

Where Ergon Energy offers a Dynamic Connection (allowing higher or variable export limits), an assessment fee of $120 typically applies. For systems requesting more than 15 kVA, the assessment fee is $391. These fees are non-refundable and cover Ergon Energy’s engineering review and connection approval process.

Ergon Communication

All Ergon connection application communications are issued via email to the Ergon account holder and the G-Solar office. Where an application incurs an Ergon fee, G-Solar will issue an additional email to the customer to ensure they are aware of the payable fee and the corresponding email issued by Ergon. Any delay in customer response may result in a delay to the progression of the Ergon application.

Where an Ergon Dynamic Connection is applicable, and following payment of the required application fee to Ergon, Ergon advises that processing may take up to sixty-five (65) business days from the date of customer acceptance of the Dynamic Connection.
