Introduction

In 2026, more and more Dutch households with solar panels are facing rising energy costs and increasing feed-in charges. For homeowners with dynamic energy contracts, exporting excess solar power to the grid is becoming less attractive than ever.

The Lunergy Hub 2400 AC offers a smart solution. With a plug-in home battery, you can store excess solar energy locally and use it later when you need it most. This reduces the amount of electricity fed back into the grid while helping you avoid buying expensive electricity during peak hours.

As a result, combining solar panels with a home battery is becoming one of the most effective ways for households to reduce long-term energy costs.

What Is a Home Battery?

A home battery is an energy storage system that allows households to store self-generated solar power for later use.

Without a battery, excess solar energy is typically exported directly to the electricity grid. However, as grid congestion increases and feed-in compensation declines, many homeowners are receiving lower returns—or even facing feed-in charges for exporting electricity.

A home battery stores surplus solar energy locally instead of sending it back to the grid. This increases self-consumption, improves the value of your solar system, and helps lower your overall electricity costs.

How Does a Plug-in Home Battery Work?

A plug-in home battery connects through a standard wall socket, making installation quick and simple. Unlike traditional home battery systems, no complex electrical work or professional installer is required.

The Lunergy Hub 2400 AC automatically monitors:

• How much solar energy your panels are generating

• How much electricity your household is consuming

• How much power would otherwise be exported to the grid

Whenever your solar panels generate more electricity than your home is using, the battery automatically stores the excess energy.

Later in the evening—or whenever electricity prices are high—your home can use the stored energy first before drawing power from the grid.

This helps you:

• Reduce feed-in charges

• Lower energy bills

• Become less dependent on the electricity grid

• Increase self-consumption of solar energy

Why Are More Households Choosing a Home Battery?

As electricity prices continue to rise and favorable feed-in schemes are gradually phased out, demand for home batteries is growing rapidly across the Netherlands.

A home battery helps homeowners:

• Gain greater control over their energy consumption

• Reduce dependence on energy suppliers

• Benefit from dynamic electricity pricing

• Avoid negative feed-in charges

• Maximize the value of their solar panels

For households with solar panels and dynamic energy contracts, a home battery can deliver substantial long-term savings.

How Does a Home Battery Reduce Feed-in Charges?

Feed-in charges occur when energy suppliers charge homeowners for exporting excess solar electricity to the grid.

This is most common:

• On sunny afternoons

• When many households are exporting electricity at the same time

• During periods of low wholesale electricity prices

A home battery helps avoid this problem by storing surplus solar energy locally instead of immediately exporting it to the grid.

The Lunergy Hub 2400 AC does this automatically. By reducing the amount of electricity sent back to the grid, homeowners can significantly reduce or even eliminate feed-in charges.

For households with larger solar installations, this can result in savings of hundreds of euros per year.

Save on Energy Costs with a Home Battery

One of the biggest advantages of a home battery is the ability to reduce electricity costs.

A home battery allows you to store low-cost or free solar energy during the day and use it later when electricity prices are higher.

This is particularly beneficial for households with dynamic energy contracts.

Example Without a Home Battery

Evening electricity consumption:

1,500 kWh × €0.40 = €600

Feed-in charges:

2,000 kWh × €0.05 = €100

Total additional annual energy costs:

€700 per year

Example With a Home Battery

With a Lunergy Hub 2400 AC, approximately 80% of evening electricity consumption can be supplied by stored solar energy.

Evening electricity costs:

Approximately €120

Feed-in charges:

€0

Estimated annual savings:

Approximately €580 per year

Actual savings depend on:

• Number of solar panels

• Electricity prices

• Energy contract type

• Household energy consumption

For many households, a home battery can reduce annual energy costs by approximately:

€500–€800 per year

---

Greater Energy Independence with a Solar Home Battery

Households with solar panels but without battery storage typically use only 30–40% of the solar energy they generate.

With a home battery, self-consumption can increase significantly.

Typical Self-Sufficiency Rate with Battery Storage

75%–90%

This means:

• Less dependence on the electricity grid

• Reduced electricity purchases from energy suppliers

• Greater use of self-generated solar energy

• Improved return on investment from solar panels

A home battery makes your solar installation substantially more efficient.

---

Why Is a Home Battery Ideal for Dynamic Energy Contracts?

With dynamic electricity contracts, electricity prices change every hour based on market conditions.

Typical pricing patterns include:

• Lower electricity prices around midday

• Higher prices during the evening peak

A home battery allows you to:

• Store low-cost electricity

• Use stored energy when prices are higher

• Avoid peak electricity rates

• Optimize energy usage automatically

As a result, the financial benefits of battery storage become even more attractive.
