What is Sunlit Memory?

The Sunlit storage unit, like the BK215 from Sunlit Solar, is a modular LFP lithium battery storage system for balcony power plants with 2.15 kWh capacity, expandable to 8.6 kWh. It stores excess solar power for night use, is Plug & Play, IP65 certified, and app-controlled. DRBO Greenenergy offers these Sunlit energy storage solutions to make the energy transition simple and accessible for private individuals.

What exactly is Sunlit storage?

The Sunlit storage unit is a compact LFP (Lithium Iron Phosphate) battery with an integrated PV hub for balcony power plants. It stores excess solar power during the day and releases it when needed. Sunlit storage revolutionizes balcony photovoltaics with its high safety and longevity. LFP cells offer up to 8,000 charge cycles and minimize fire risks compared to other battery technologies. DRBO Greenenergy integrates this advanced technology into its energy storage solutions. The modular design allows for flexible expansions, suitable for growing energy needs.

How does the Sunlit storage unit work?

The Sunlit storage unit automatically charges with excess solar power and discharges when consumption increases. The app controls the feeding and monitoring in real time. The storage unit is equipped with an intelligent energy management system that allows for automatic discharge when solar production decreases. When the storage unit is full, excess power is fed into the grid, as long as it is below the feed-in limit. DRBO Greenenergy emphasizes compatibility with bidirectional inverters to also charge grid power if needed.

What are the technical specifications of the Sunlit storage unit?

The Sunlit BK215 offers a usable capacity of 2.15 kWh and an efficiency of 83% at a load of 800 W. The storage unit has IP65 protection and can be controlled via an app. Technical highlights include LFP cells that allow for full discharge (DoD), a discharge power of up to 800 W, and an auxiliary heater for winter operation. Expansion modules can be easily stacked and connected without additional wiring. This expandability makes the storage unit future-proof and flexible.

How to install the Sunlit storage unit?

Installing the Sunlit storage unit is very simple and does not require any special electrician knowledge. Simply plug the modules together, connect the MC4 cables, and plug the Schuko plug into the mains. The app is configured via Bluetooth or WiFi to control the feed-in and settings. DRBO Greenenergy provides complete packages with brackets and cables. The storage unit should be installed in a shaded location, and grounding is required to ensure safety standards. After installation, you can test the charge cycles and put the storage unit into operation.

Why is the Sunlit storage unit expandable?

The Sunlit storage unit can be modularly expanded by adding up to three additional modules, each with a capacity of 2.15 kWh, reaching a maximum total capacity of 8.6 kWh. This expandability makes it possible to adapt the storage capacity to increasing energy demand, whether for higher household consumption or for supporting electric car charging. Thanks to the plug-and-play system, no additional cables are needed, and communication between the modules is automatic.

What are the advantages of the Sunlit storage unit?

The Sunlit storage unit offers numerous advantages: It enables high self-sufficiency, especially during periods of low solar output, and reduces electricity costs through self-consumption. Its high efficiency and longevity help to amortize the investment in the long term. In addition, the storage unit saves up to 50% of electricity costs. The app functionality allows for easy monitoring and management of energy. DRBO Greenenergy emphasizes that the Sunlit storage unit is particularly suitable for tenants, as it is easy to install and requires no structural changes.

What are the disadvantages of the Sunlit storage unit?

The Sunlit storage unit also has some disadvantages: At a low load of approximately 150 W, the efficiency drops to 73%. Additionally, there is no true bypass mode, which can lead to a slight delay in morning operation. The app, while very practical, might take some getting used to for new users. The storage unit is also not optimized for use in high-power PV systems. However, DRBO Greenenergy ensures that these challenges are minimized through continuous updates and support.

Is the Sunlit storage unit cost-effective?

Yes, the Sunlit storage unit offers high cost-effectiveness. With a payback period of 2 to 3 years, thanks to savings of €0.30-0.40 per kWh and government subsidies, the storage unit is an attractive solution. The low price per kWh of approximately €250/kWh and the long lifespan contribute to reducing costs. If you store 3 kWh of excess electricity per day, you can save up to €300 in electricity costs annually.
