Is solar battery storage suitable for small homes?

Solar battery storage systems like the SunEnergyXT BK215 2.15 kWh are excellent for small homes. They store excess solar power for later use, increase self-consumption, and help reduce energy costs. With a simple plug-and-play setup from DRBO Greenenergy, homeowners can significantly increase their energy independence and benefit from high profitability.

What is a solar battery storage system for small homes?

A solar battery storage system is designed to store excess solar power generated during the day for later use. For small homes, storage systems with a capacity of 2-3 kWh are sufficient to power essential household appliances such as lighting and refrigerators. The SunEnergyXT BK215 with 2.15 kWh is an excellent choice. It is modularly expandable up to a capacity of 8.6 kWh and offers IP65 certification, making it suitable for indoor and outdoor use.

Thanks to the use of lithium iron phosphate batteries (LiFePO4), solar battery storage systems offer a long lifespan of over 6,000 cycles. A decisive advantage for small homes is that these storage systems maximize the self-consumption of solar power and reduce electricity drawn from the grid, leading to significant long-term savings.

What are the advantages of solar battery storage?

Solar battery storage systems offer a number of advantages, particularly for small homes with balcony power plants. By storing solar power, households can reduce their electricity costs by 20-50%, increase their independence from energy providers, and protect themselves from power outages. Another important plus is the promotion of sustainability through CO₂ savings.

The combination of efficient self-consumption and emergency power supply makes storage solutions like those from DRBO Greenenergy particularly attractive. By using excess solar power during the night, up to 80% of the electricity produced can be consumed in the household.

What are the costs of a solar battery storage system?

The costs of a solar battery storage system vary depending on capacity and provider. For a capacity of 2 kWh, prices range between €700 and €1,200, including installation. The SunEnergyXT BK215 costs approximately €900 and can be financed from €25 per month. Generally, the costs for a solar battery storage system amortize within 3 to 5 years at an electricity price of 33 cents/kWh.

For larger models with a capacity of 5 kWh or 8 kWh, prices can range between €1,500 and €4,000. The benefit of this investment is shown in the long-term savings through the self-consumption of solar power, which does not have to be drawn from the grid.

When is a solar battery storage system worthwhile?

A solar battery storage system is particularly worthwhile when the self-consumption of the generated solar power is over 30% and electricity prices are high. The storage system allows access to stored energy even during grid fluctuations or power outages. For small homes with balcony solar systems, amortization is generally possible within 3 to 7 years.

However, the profitability of a storage system depends on various factors such as consumption and annual electricity production. With a production of 300-400 kWh per year and an electricity price of 33 cents/kWh, amortization can occur within 4 years.

Calculation example:

• Purchase cost: €900

• Annual savings: €100–150

• ROI (Return on Investment): 6–9 years

How to install a solar battery storage system?

The installation of a solar battery storage system like the SunEnergyXT BK215 is simple and usually takes only 30 to 60 minutes. The installation includes connecting the storage system to the PV system and the grid, as well as configuration via the associated app. Models up to 800 W do not require an electrician; for higher outputs, inspection by a specialist is necessary.

Step-by-step guide:

1. Choose a suitable installation location (dry, shady).

2. Connect the system: PV → storage → mains plug.

3. Set up a Smart Meter (e.g., Shelly).

4. Register in the app for usage optimization.

Which solar battery storage system is the best?

The SunEnergyXT BK215 is an excellent solar battery storage system due to its capacity of 2.15 kWh and expandability up to 8.6 kWh. Other recommended models include the Anker SOLIX 3 Pro and the Solakon ONE. For use in small homes, it is advisable to rely on the safety of LiFePO4 battery technology.
