Sustainable Power

As energy costs continue to rise and the demand for sustainable power soars, homeowners and businesses across the South Coast are increasingly turning to solar energy. But the real game-changer in 2025? Growatt battery storage systems. These powerful solutions allow you to maximise your Feed-in Tariff (FiT) returns and take full control of your solar energy use.

In this post, we’ll explore how you can benefit from integrating a Growatt battery, including the Growatt AXE 5.0L 5kWh LV battery, into your solar setup. We’ll also guide you through key battery models like the Growatt GBLI6531 and the compact Growatt NOAH 2000, ensuring you make a smart investment for the future.

Why Battery Storage Matters in 2025

The Feed-in Tariff may have closed to new applicants, but for those already signed up or using similar smart export guarantees (SEGs), battery storage is essential. Why?

Because your solar panels don’t always generate power when you need it most — and that’s where batteries shine.

By storing excess electricity for later use, solar panel batteries reduce reliance on the grid and increase the amount of energy you use from your own solar system. This, in turn, boosts your FiT benefits or SEG payments.

The Growatt battery price UK market has become more competitive, making this year the perfect time to invest in energy storage solutions.

Spotlight on the Growatt AXE 5.0L Battery

The Growatt AXE 5.0L 5kWh LV battery is ideal for UK homeowners and businesses looking for scalable and affordable storage. Here’s why it’s a top pick in 2025:

• Modular design: Expand your capacity up to 40kWh.
• Advanced BMS (Battery Management System) for longevity and safety.
• Seamless integration with Growatt inverters and solar setups.
• Compact footprint, making it ideal for properties with limited space.

Whether you’re running a busy household or managing a commercial space, this model offers enough juice to keep things running smoothly after sundown.

Meet the Growatt GBLI6531: High Voltage, High Performance

For larger setups or advanced hybrid systems, the Growatt GBLI6531 offers robust performance with a 6.5kWh storage capacity and high-voltage compatibility. It’s perfect for users aiming to store larger volumes of solar energy and maximise both FiT and SEG returns.

Key features include:

• High-voltage lithium-ion storage for efficiency.
• Long lifespan (over 6,000 cycles).
• Smart monitoring via the ShinePhone app.

This battery is designed for serious solar users who want to future-proof their system and scale as energy needs grow.

Compact Solution: The Growatt NOAH 2000

If space or budget is limited, the Growatt NOAH 2000 is an excellent entry-level option. It provides:

• 2kWh of storage, suitable for small homes or flats.
• Stylish and space-saving design.
• Integration with Growatt inverters and monitoring systems.

This model is especially popular among those in cities or coastal areas like Portsmouth or Brighton where space is at a premium.

Feed-in Tariff and SEG: What You Need to Know

Even though the Feed-in Tariff closed to new applicants in 2019, those already enrolled still receive payments for the electricity they generate and export. Meanwhile, the Smart Export Guarantee (SEG) introduced by the UK government ensures energy suppliers pay you for surplus energy sent back to the grid.

To maximise either scheme, battery storage is vital. With a Growatt battery, you can:

• Time your energy usage more efficiently.
• Export less during low-tariff periods and save energy for peak times.
• Reduce dependence on the grid entirely during certain periods.

How Much Does a Growatt Battery Cost in the UK?

The Growatt battery price in the UK can vary based on capacity, model, and installation specifics:

• Growatt AXE 5.0L: Around £2,000 – £2,800 (excluding inverter).
• Growatt GBLI6531: Approx. £3,000 – £4,000.
• Growatt NOAH 2000: Between £1,200 – £1,800.

These prices offer excellent value, especially when compared to energy savings and the potential boost in SEG payments over time.
