How do I increase the size of an inverter of an existing renewable energy system?
If you already have rooftop solar installed and wish to increase the size of your inverter, or if you wish to add an inverter beside an existing inverter, you must apply to Horizon Power and receive written approval before carrying out this work. Approval is subject to the eligibility rules for new renewable energy customers and the technical requirements.
Notice for Feed-in Tariff customers
An application for a larger or additional inverter is not eligible for FiT, even if you currently receive FiT. You would lose any existing FiT payments, because the scheme was suspended by the State Government from 1 August 2011 for new applications.
For example, if you are a residential customer with a 3 kW inverter and wish to increase the size to 5 kW, you need to submit a new application for 5 kW. If you meet the eligibility rules, and capacity is available, the application will be approved. The buyback price is as per the Renewable Energy Buyback pricelist at the time of the new application. However, you will lose any FiT payment you currently receive from the Government.
