Frequently Asked Questions About Off-Grid Power
What is the difference between off-grid solar and a normal solar system?
A standard solar installation generally remains connected to the electricity grid. An off-grid system needs to provide the property's electricity independently, which normally requires solar generation, battery storage, inverter equipment, system controls and another source of backup generation where required.
How big does an off-grid solar system need to be?
There is no standard system size. It depends on daily energy consumption, peak demand, location, seasonal solar production, equipment starting loads, battery requirements and how the property will be used.
Do off-grid systems need a generator?
Generators remain an important part of many off-grid systems because they provide another source of generation during extended poor weather, abnormal consumption or other operating conditions. Whether one is required and how it is sized depends on the application.
Can an off-grid system provide three-phase power?
Yes. Off-grid systems can be designed for single-phase or three-phase applications. Three-phase systems are commonly used for larger homes, agriculture, workshops, commercial facilities, pumps and industrial equipment.
Can an off-grid system run air conditioning?
Yes, provided the solar, battery and inverter system has been designed around the additional energy and peak-power requirements.
Can I expand an off-grid system later?
Often, yes. Expansion should ideally be considered during the original system design so additional solar generation, battery storage or inverter capacity can be incorporated without unnecessarily replacing existing equipment.
Is off-grid solar suitable for a farm or commercial operation?
Yes. Off-grid systems can range from relatively small installations through to substantial commercial power systems. Farms and commercial sites require more detailed assessment because motors, pumps, refrigeration, machinery, operating hours and three-phase loads can substantially affect system design.
Can MyEnergy install off-grid systems anywhere in Australia?
MyEnergy delivers off-grid and remote power projects across Australia. The approach to installation depends on project size, location, site access and the level of work required.
What should I check when comparing off-grid solar kits?
Off-grid solar panel kits should be assessed against the whole property's needs, including daily energy use, overnight battery demand, equipment starting loads and winter solar production. A list of panels, batteries and an inverter does not establish whether those components will work together or provide enough power throughout the year.
When comparing off-grid solar kits, check what the proposal includes: system design, mounting, installation, generator integration, commissioning, monitoring and ongoing support. Tell the designer about future buildings, pumps or other planned loads. This helps you compare complete systems on the same basis and identify what may need to change as the property develops.
