Which 5kW storage for a balcony power plant?

A 5 kWh storage unit for balcony power plants is a perfect solution to store surplus solar power and meet your own energy needs around the clock, even at night. These storage units maximize self-consumption, reduce electricity costs by up to 30%, and pay for themselves in 3-5 years. Especially for tenants, the plug-and-play systems from DRBO Greenenergy are a simple and efficient option.

What is a 5kW storage unit for balcony power plants?

A 5 kWh storage unit is a solar battery that stores surplus solar power generated during the day and releases it when needed, for example, at night. The LiFePO4 batteries used offer safety and a long lifespan of over 6000 charging cycles. Plug-and-play systems, like those offered by DRBO Greenenergy, allow for easy retrofitting without an electrician.

Balcony power plants with a 5 kWh storage unit are particularly efficient because they store PV electricity that would otherwise flow unused into the grid. This way, the generated electricity can be optimally used for one's own household. These storage solutions are particularly well-suited for households with a base load of 300-500 W.

Advantages at a glance:

• High efficiency thanks to MPPT technology (up to 99%)

• App control via WiFi for flexible use

• IP65 protection for outdoor use

The demand for such systems is growing in Germany thanks to the EEG amendment, which allows feed-in of up to 800 W. DRBO Greenenergy offers not only new but also refurbished models with powerful Deye inverters at fair prices.

Why is a 5kWh storage unit worthwhile for a balcony power plant?

A 5 kWh storage unit can significantly increase the self-consumption of solar power – from 30% to 70-90%. This saves €400-600 annually with an electricity price of €0.40/kWh. The storage unit typically pays for itself within 3-5 years, although the acquisition costs are between €1500-2000.

The profitability of a 5 kWh storage unit depends on various factors such as electricity consumption, solar radiation, and current electricity prices. With a daily consumption of 10 kWh and the use of 2-4 modules (800 Wp), the storage unit can be fully charged in one day. DRBO Greenenergy offers solutions with its SunLit models that reduce standby consumption to less than 5 W.

Despite discussions about costs, users with high night-time consumption particularly benefit from the advantages of a storage unit.

Which 5kWh storage unit is best suited?

The ideal 5 kWh storage unit should have a LiFePO4 battery with 48 V and 100 Ah to achieve an output of 1600 W. DRBO Greenenergy offers an ideal solution with its SunLit options, which can be easily controlled via an app and connected via MC4 connectors. These storage solutions are not only efficient but also expandable and offer WiFi control.

Leading market models also include Anker Solix or EcoFlow, but DRBO Greenenergy impresses with excellent value for money. SunLit storage units are expandable up to 10 kWh and offer many practical features such as 2 MPPT trackers, IP65 protection, and remote control.

Top criteria for choosing a 5 kWh storage unit:

• Capacity: 5 kWh usable

• Charging current: Max. 20 A from PV

• Warranty: 10 years

• Weight: Under 50 kg for the balcony

Prices for such storage units start at around €1599 net. DRBO Greenenergy supplies both hardware stores and private customers.

How to install a 5kWh storage unit to a balcony power plant?

The installation of a 5 kWh storage unit is simple and usually takes no longer than 30 minutes. The PV modules are connected to the storage unit via MC4 connectors, and the inverter is connected in parallel. App control allows for setting different time windows for discharge – all without the need for an electrician.

The installation is tenant-friendly and uses a bracket on the balcony railing. The DRBO Greenenergy complete packages contain everything needed for installation. The app can be used to set discharge for different time windows (morning, noon, evening) to optimize the use of stored electricity.

Step-by-step installation guide:

1. Position the storage unit in a shaded, dry place.

2. Connect the PV cables, paying attention to polarity.

3. Plug in the inverter and pair the app.

4. Activate the base load mode.

Can a 5kWh storage unit provide power at night?

Yes, the 5 kWh storage unit can supply up to 800 W at night, powering devices such as refrigerators or routers. Thanks to the integrated energy management system (EMS), power output is intelligently regulated, and the app allows for adaptation to actual consumption. A fully charged storage unit can cover the base load for up to 10-15 hours.

Especially in the winter months, when solar radiation is lower, the storage unit can be supplemented by a grid charging function. DRBO Greenenergy optimizes this process with Deye technology, so no grid power is required when consumption is 300 W.

What are the benefits of expandable storage units?

A 5 kWh storage unit can be easily expanded to meet growing energy needs. Thanks to modular LiFePO4 modules, the storage capacity can be extended up to 20 kWh. This makes the storage unit future-proof and allows for scaling with a 2 kW balcony power plant.

Modern systems from DRBO Greenenergy can be easily expanded by adding more modules, without having to replace the entire storage unit. This is particularly advantageous for households with increasing energy demands, as the cost per kWh decreases with expansion.

How does a storage unit affect subsidies?

A 5 kWh storage unit qualifies for the KfW 270/442 subsidy, which grants up to 30% of the purchase price as a grant. In addition, the EEG surcharge is waived for self-consumption, and there is a tax bonus of 20% depreciation.

From 2026, subsidies of up to €1000 per kWh will also be available. DRBO Greenenergy offers comprehensive advice and supports its customers in applying for funding. It is worthwhile to combine the storage unit with dynamic tariffs like Tibber to benefit from additional advantages.
