5 Best Solar Battery Storage in Australia Under $10,000
5 Best Solar Battery Storage in Australia Under $10,000
[Updated 2024]
Do you want the best solar battery storage for your home or business? If yes, the available options in the market could be confusing for new solar consumers. Fortunately, solar technology has evolved greatly, and lithium-ion power backups are one of the modular ways to store solar power. However, there is no universal mechanism to select the best solar battery, and solar users might opt for under-power backups that may result in less optimal solar system performance. To make your decision easy, we have sorted the five best solar batteries in Australia. So, let’s get started!
WHAT ARE THE 2 REASONS FOR WRONG SOLAR BATTERY SELECTION?
Solar consumers make two mistakes while selecting solar batteries:
UNDERSIZE SOLAR BATTERY
These power backups do not meet the users’ power demands and can cause:
- Low power storage.
- Decreased energy independence.
- Lower cost savings.
- Improved conventional grid dependence.
- Solar battery wear and tear.
- Limited backup energy during outages.
- So, assure apt battery size as per your needs to avoid these issues.
OVERSIZE SOLAR BATTERY
On the other hand, bigger-sized solar batteries also fail to store adequate energy for charging, more commonly during winter, and can result in:
- Raised initial cost.
- Decreased efficiency.
- More extended payback period.
- Bigger space requirements.
- Potential environmental impact.
Solar users can avoid this issue by:
- Selecting the correct solar array size.
- Select apt system connection: on-grid or off-grid.
- Evaluating daily power consumption (kWh).
TYPES OF LITHIUM-ION BATTERIES
We understand that it could be challenging for new solar users to select the apt power backup at an affordable cost. The good news is that lithium-ion solar batteries are the best options with specific features. However, most of these solar batteries are compatible with distinct inverters. For instance, high-voltage solar batteries coupled with suitable HV hybrid inverters.
So, before investing in solar batteries, consider the subsequent criteria:
- Usable Storage Capacity
- Efficiency
- Cycle Life
- Operating Temperature
- Warranty
- Cost
- Weight
- Size
With the above reference, here are our top 5 picks for the best solar battery storage in Australia under $10,000.
