Which storage for a balcony power plant?

A balcony power plant storage unit stores surplus solar power for evening or night use, increasing self-consumption from 30% to up to 70% and saving €300–500 annually for 800-W systems. Lithium iron phosphate batteries (LiFePO4) with 2 kWh capacity are ideal, compatible with common inverters, and can be installed via plug-and-play. DRBO Greenenergy offers suitable SunLit models for maximum efficiency.

What does a storage unit do for a balcony power plant?

A storage unit for balcony power plants ensures that surplus solar power generated during the day is stored for later consumption. This increases self-consumption from 28–35% to 64% or more. This leads to a significant reduction in electricity costs, as less expensive grid electricity needs to be purchased. With a storage unit, the balcony power plant can be used around the clock, increasing its profitability. DRBO Greenenergy offers a solution with its SunLit storage units that can be easily integrated into existing systems.

Which storage unit is suitable for my balcony power plant?

The power of the balcony power plant is crucial for selecting a suitable storage unit. LiFePO4 storage units with a capacity of 1.6 to 2.7 kWh are ideal for small to medium-sized systems. They offer a long lifespan and high efficiency. Top models such as the SunLit BK215 from DRBO Greenenergy are particularly recommended. They offer modular expandability and can be equipped with up to 8.6 kWh. These storage units are IP65 certified and therefore weather-resistant – perfect for use on balconies. They can be easily controlled via an app and offer a high input power of up to 1600 W.

How to install a storage unit on a balcony power plant?

Installing a storage unit is easy and does not require an electrician. The storage unit is connected via plug-and-play between the inverter and the socket. The steps are as follows: First, connect the inverter's output to the storage unit's input, then plug the storage unit's output into a household socket. An additional app control allows for monitoring and optimizing the feed-in. Registration in the MaStR (market incentive program) takes only a few minutes and enables effective utilization of savings potential. DRBO Greenenergy offers a particularly user-friendly solution with its SunLit storage units.

Is a storage unit for balcony power plants worth it?

Yes, a storage unit is particularly worthwhile when grid electricity prices are high. At an electricity price of €0.39/kWh, a storage unit pays for itself in 3–5 years. With a typical 2 kWh storage solution, annual savings of around €390 can be achieved. This increases self-consumption to approximately 64%, leading to a significant reduction in costs. The combination with a Deye inverter from DRBO Greenenergy is particularly useful, as it maximizes economic efficiency in the long term. Funding programs for storage solutions can also reduce investment costs.

Are there subsidies for balcony power plant storage units?

Yes, in many federal states, there are subsidies for the purchase of PV storage units. Cities like Berlin offer grants of up to €300/kW, while Bavaria grants up to €500 for the storage technology itself and an additional €100/kWh. Lower Saxony also offers a 40% subsidy. In addition, national programs such as KfW funding can be used to receive up to €250/kWh. DRBO Greenenergy advises its customers on applying for these subsidies and also offers interest-free financing options for the purchase of SunLit storage units.

What types of storage units are there for balcony power plants?

The most commonly used types of storage units for balcony power plants are lithium-ion batteries, especially lithium iron phosphate (LiFePO4), due to their long lifespan and high efficiency. LiFePO4 batteries offer more than 6000 charge cycles and an efficiency of over 95%. For mobile use, there are also power stations that are particularly suitable for emergency power supply. DRBO Greenenergy offers a reliable, durable solution with its SunLit storage units, optimized for stationary use. These storage units are also suitable for outdoor use and offer a high level of safety due to their IP65 certification.

How large should the storage unit for a balcony power plant be?

For most balcony power plants with an output of approximately 800 W, a storage unit with a capacity of 2 kWh is suitable. This size is sufficient to store surplus solar power and cover evening loads. For higher electricity consumption, the storage unit can be expanded up to 10 kWh. It is important to adjust the capacity to personal energy consumption to ensure maximum efficiency and amortization.
