About this product
Why choose 5 kWh over other sizes
The Growatt APX 5 kWh battery is the ideal entry point into premium solar storage for small homes and apartments with a modest energy demand and a 3–4 kWp PV system.
If your main goal is to cover the evening peak (lighting, fridge, TV and small appliances) without overspending on storage, 5 kWh strikes a great balance between investment and savings.
Compared to the 10 kWh and larger versions, this capacity is tailored to users who are away during the day but want to store midday solar production to reduce grid imports when tariffs are highest.
You still benefit from all APX flagship features: safe LiFePO4 chemistry, advanced BMS with cell-level protection and seamless compatibility with Growatt hybrid inverters.
Who is this battery for?
This battery suits well-insulated smaller homes without large electric heating loads or EV charging, where electricity bills are moderate and the focus is on maximising self-consumption in the evening.
If your needs grow over time, you can expand the system by adding more APX modules up to much higher capacities without replacing the existing battery.

Frequently Asked Questions
What type of home is the Growatt APX 5 kWh battery designed for?
It is designed for small houses and apartments with a 3–4 kWp solar system and moderate consumption, where the main goal is to cover the evening peak without a large upfront investment.
Can I upgrade later if 5 kWh is not enough?
Yes. The Growatt APX series is modular, so you can start with 5 kWh and add extra battery modules later, scaling the system as your energy use increases.
Is 5 kWh a good choice if I am away most of the day?
Yes. It allows you to store excess solar generated at midday and use it in the evening, improving self-consumption and reducing grid purchases in the most expensive hours.
