5 Best Solar Battery Storage in Australia Under $10,000

Find out which of solar battery under $10,000 is right for your home. We take an in-depth review of their features and how suitable they are for your home.

Do you wish to get a solar battery for your home on a budget? If so, the choices in the market can be confusing. With changing Lithium-ion technology, today, you have modular and smart systems for energy storage. Unfortunately, there isn’t any one-size-fits-all method when it comes to battery selection. A wrong battery system selection leads to poor solar system performance.

This is usually due to 2 reasons which include:

Undersized Battery:

Undersized batteries don’t meet the energy demands of your house.

Oversized Battery:

Oversized batteries can fail to store sufficient power for charging, generally during winters.

This issue is avoidable by selecting your battery according to:

  • Size of the solar array
  • System type (off-grid or on-grid)
  • Daily average energy consumption (kWh)

Lithium Batteries: What are the Types?

For a solar battery noob, selecting the right one can be challenging. Each type comes with its specific features. Most lithium batteries available in the market work with specific inverters. For example, high-voltage batteries can be paired with a compatible HV hybrid inverter.

Other batteries like Redback smart hybrid have AC-coupled battery that utilizes inbuilt inverters. This enables the battery to be fitted with existing solar power systems. Apart from this, there are rack-mounted and modular batteries available. These batteries can perform well with various off-grid inverters.

When purchasing a solar battery, you have to judge it on the following criteria:

  • Efficiency
  • Usable Storage Capacity
  • Cycle Life
  • Operating Temperature
  • Cost
  • Warranty
  • Size
  • Weight

Keeping this in mind, here is a list of the best solar battery storage in Australia under $10,000.
