Can a balcony solar power system with storage also supply electricity at night?

A balcony solar power system with storage is the perfect combination of sustainability and efficiency. It allows you to use not only the solar power you generate during the day but also when the sun has long set—at night. But how does this actually work? Can a balcony solar power system really supply electricity at night? And if so, how much?

In this article, we get to the bottom of this question and take a deep dive into the functionality of a balcony solar power system with storage. We will also look at the role of the Indevolt BK1600, an advanced system specifically developed for the German market. With a mix of practical explanations, tables, and examples, you will know exactly how a balcony solar power system with storage can supply you with energy even after sunset by the end.

How Does a Balcony Solar Power System with Storage Work?

A balcony solar power system with storage consists of two main components: the solar modules, which convert sunlight into electricity during the day, and the battery storage, which stores this electricity. During the day, the solar modules often produce more energy than you can use directly. This surplus energy is charged into the storage unit so it can be used later—for example, in the evening or at night.

Why doesn’t a balcony solar power system without storage supply electricity at night?

Balcony solar power systems without storage feed the generated electricity directly into your home grid. If the electricity is not used immediately, it is lost to the public power grid. Once the sun sets, there is no more electricity, as solar modules cannot generate energy without light. A storage unit like the Indevolt BK1600 solves this problem by storing the surplus electricity for nighttime use.

Can a balcony solar power system without storage also supply electricity at night?

Yes, a balcony solar power system with storage can supply electricity at night—and it is exactly the electricity that was stored in the unit during the day. However, how long and how much electricity is available depends on several factors:

1. Storage Capacity

The size of the storage unit determines how much energy you can use at night. The Indevolt BK1600 has a capacity of 1.6 kWh, which is sufficient for most households to supply electricity for several hours.

2. Energy Consumption

The electricity consumption of your devices directly affects how long the stored energy lasts. Energy-efficient devices significantly extend the usage time.

3. Storage Charge Level

Was the storage unit fully charged during the day? If yes, you can access the full storage capacity at night.

4. System Efficiency

Systems like the Indevolt BK1600 operate with very high efficiency, so there is barely any energy loss during charging and discharging.

How Much Energy Can Be Used at Night?

To answer how much electricity a balcony solar power system with storage can supply at night, let’s look at how the Indevolt BK1600 works in practice. With a capacity of 1.6 kWh, you can power a variety of devices. The table below shows examples of how long different devices can be used with a fully charged battery:

Device	Power Consumption (W)	Runtime with 1.6 kWh Storage
LED Lamp	10 W	160 Hours
Laptop	50 W	32 Hours
Refrigerator	100 W	16 Hours
TV	150 W	10.6 Hours
WLAN Router	15 W	106 Hours
Mobile Phone Charger	5W	320 Hours

Practical Example:

Suppose you use an LED lamp (10 W), a TV (150 W), and a router (15 W in the evening. The total power consumption is 175 W. With a fully charged Indevolt BK1600, you could run these devices for approximately 9 hours—enough to keep your space comfortably supplied with electricity throughout the entire night.

Difference: Balcony Solar Power System With and Without Storage

The following table shows the differences between a balcony solar power system with storage and one without storage, particularly regarding usage at night:

Feature	Without Storage	With Storage
Usage During the Day	Direct consumption, surplus goes to the grid	Direct consumption, surplus is stored
Usage at Night	Not possible	Stored electricity can be used
Self-Consumption Share	Approx. 20–30 %	Up to 70–80 %
Grid Independence	Low	High
Efficiency	Dependent on direct consumption	Higher, as surpluses are utilized

With a storage unit like the Indevolt BK1600, you can significantly increase your self-consumption and are no longer dependent on the public grid—even at night.

The Advantages of the Indevolt BK1600 for Nighttime Power Supply

The Indevolt BK1600 is a specially developed storage unit for balcony solar power systems, offering you numerous advantages not only during the day but also at night. Below are the key features that make it stand out:

1. High Storage Capacity

With 1.6 kWh, the Indevolt BK1600 provides enough capacity to cover your basic electricity needs at night.

2. Efficient Battery

The system’s lithium-ion battery is characterized by long service life and high efficiency. With a PV-DC conversion efficiency of 97%, almost all generated electricity is stored.

3. Plug-and-Play Installation

Unlike many other systems, the Indevolt BK1600 does not require professional installation. This saves time and costs.

4. Intelligent Control

Thanks to AI-based optimization, the available energy is used efficiently. The storage unit knows exactly when it is sensible to supply electricity, thereby optimizing your self-consumption.

5. Suitable for Emergencies

The Indevolt BK1600 can also be used as an emergency power supply in the event of a power outage. This ensures you are always protected.

How to Maximize the Use of a Balcony Solar Power System with Storage

To ensure your balcony solar power system with storage works optimally, you can adopt some simple strategies:

1. Adjust Energy Consumption

Use energy-intensive devices such as washing machines or dishwashers during the day, when the solar modules are actively generating electricity. This leaves the storage unit available for nighttime use.

2. Use Efficient Devices

Energy-saving devices like LED lamps or low-power refrigerators significantly extend the usage time of the stored electricity.

3. Optimize Charging Times

Systems like the Indevolt BK1600 support time-based charging schedules, allowing you to charge the storage unit specifically when it is most sensible.
