SolaX Power’s X Hybrid series‘Smart inverters’ that are available with or without SolaX-branded charger, battery bank and battery cabinets. The company also offers an all-in-one product called the Solax Box. (You can also check out SolaX’s highly informative, interactive demo of how a hybrid inverter works.)

Sonnen is a German-based battery storage & energy management system developer who have a range of high-quality products available on the Australian market.

Panasonic has introduced a storage system of its own which will be available through certain utilities.

-Immediately after its announcement, Tesla’s PowerWall quickly became seen as a benchmark for Australia’s battery storage industry both on price and performance.

Victron Energy’s ECOmulti: The ECOmulti is a complete energy storage solution (designed for solar PV system integration but deployable without solar PV as well) whose default setting is to optimise for ‘self-consumption’–i.e. maximising energy independence for homes and businesses. Victron also offers a number of other energy storage products. (More details coming soon.)

Plug-and-play energy storage devices in Australia

All-in-one, plug-and-play battery storage solutions tend to be the easiest to understand for homeowners. Plug-and-play systems usually come in the form of a box or cabinet that contains virtually everything (beside the solar panels and their cabling) that a household needs to increase their energy independence in one fell swoop.

An all-in-one device will generally include:

  • a hybrid (solar & battery) inverter,
  • a battery bank,
  • battery management system (if required),
  • energy management system (if included),
  • communications equipment, and
  • any requisite cabling and wires.

Hi Pete,

Sorry, we’re not really experts in batteries for caravans. You could check out RV Solar Supplies, though.
