About this product
Why choose 30 kWh over other sizes
The Growatt APX 30 kWh battery is the top-capacity option in the range, designed for users who want to come as close as possible to off-grid operation while keeping the grid as a safety net.
Compared to 20 or 25 kWh, 30 kWh can sustain very high consumption for several consecutive days, which is crucial for large properties with multiple EVs, intensive electric heating or cooling, pools and other big loads running in parallel.
It is ideal for homeowners who put autonomy first, such as heavily used second homes, rural properties with unreliable grid supply or residential projects that want to minimise external energy use as much as possible.
If your PV array is sized to generate substantial midday surplus, 30 kWh lets you store a very large share of that energy and shift it to the times when it has the highest value, reducing the need to further oversize your panels.

Frequently Asked Questions
What kind of projects call for 30 kWh?
Very large homes, properties in areas with unstable grids or users who want to operate as close to off-grid as possible while keeping the grid as backup.
Is 30 kWh too much for a standard home?
For most typical homes, 30 kWh would be excessive and is usually reserved for very high consumption scenarios or special autonomy requirements.
Can I start smaller and grow to 30 kWh later?
Yes. Thanks to the modular APX design, you can begin with a lower capacity and gradually expand up to 30 kWh as your needs increase.
