Sungrow – 9.6kWh Battery
Sungrow batteries are stackable modules that provide storage starting at 9.6kWh. These lithium iron phosphate batteries can scale up when stacked to provide varying levels of usable stored energy. Suited to residential and commercial use, Sungrow batteries provide reliable, seamless storage and full blackout protection when teamed with the Sungrow hybrid inverter.

Tesla Powerwall – 13.5kWh Battery
Tesla’s second generation Lithium-ion ‘Powerwall’ has a usable energy storage capacity of 13.5kWh. As an AC-coupled battery, Powerwall can be fitted to virtually any existing solar power system. It also works perfectly as part of a new solar and battery system and is suitable for residential and light commercial use.

Some of your FAQs...
iS A BATTERY REQUIRED IF YOU WANT TO INSTALL SOLAR PANELS?
No. Most homes with solar currently do not have battery storage. If you are fine to draw energy from the grid when the sun isn't shining, and are prepared to be off-line when there's a power outage, then solar only is just fine.
How long will a home battery last?
Like solar panels, battery performance naturally degrades over time until it reaches a point where it is no longer useful or recommended to continue operating. Factors that influence the lifespan of a lithium-ion solar battery are the battery type, usage, ambient temperature, manufacturer/model of the battery, and maintenance. Lithium-ion batteries offer 500-1000 cycles before degradation and have an operational lifespan of 10+ years. However, if a lithium-ion battery is affected by high temperatures, or deeply drained at any time, this affects that lifespan.
do i lose my feed-in-tariff payments from my solar pv if i install a home battery system?
If you currently receive feed-in-tariff (FiT) payments for the electricity you generate with your solar PV, they will not be affected if you install a home battery system. The FiT scheme was discontinued for new home PV systems installed on or after 1st April 2019, but existing qualifying households won't lose any of these payments for the contract term (usually 20 years from installation) if they do install a battery.
does a home battery work during a power outage?
Some home battery systems can power your home in the event of a power cut, but not all. Batteries need to have an 'islanding' capability to ensure there is no risk of any form of electricity generation creating a risk to people working on the lines to restore power. To get past this, backup battery systems can have a relay to physically disconnect the electricity supply in a building from the grid (called islanding). It detects a drop in voltage on the grid in the event of a power outage, and disconnects the home from the grid.
what size home battery do i need?
This depends on the size and energy requirements of your home. The average household uses between 8-10 kWh of electricity per day. Home storage batteries start at around 2.5 to 5 kWh in capacity for small systems, up to large systems at 13 to 15 kWh. You will generally need to determine how much energy you use at night, particularly if you intend to maximise your solar use during the day when the sun is shining. Take into account your fridge, TV, lights, heating and cooling etc. Bear in mind that during winter there may be times when you need to draw from the grid if there hasn't been enough sun to add to the batteries.
what are veec's and stc's?
VEECs are Victorian Energy Efficiency Certificates that represent the amount of carbon dioxide equivalent (CO2-e) in tonnes that would be displaced by the use of the installation. The rebate is taken off the price of your system by your installer.
Australian Government Small-scale Technology Certificates represent the amount of electricity in megawatt hours (MWh) that would be displaced by the use of the solar water heater over its lifetime of up to 10 years. One STC is equivalent to one MWh of electricity offset by the solar water heater. The rebate is taken off the price of your system by your installer.
