Sunlit B215 Expansion Memory: What is it?

The Sunlit B215 expansion storage adds 2.15 kWh of storage capacity to balcony power plants and can be modularly expanded up to 8.6 kWh. With IP65 protection and MPPT input, it is ideal for tenants and homeowners. DRBO Greenenergy offers compatible SunLit solutions for easy plug-and-play installation.

What is the Sunlit B215 expansion storage?

The Sunlit B215 is a modular additional storage unit with 2.15 kWh capacity for balcony power plants, which can be expanded up to 8.6 kWh by adding up to three modules. The storage unit stores excess solar energy and enables self-sufficient use when needed, making it ideal for households with increasing energy demands.

The B215 from SunLit revolutionizes balcony photovoltaics with its stackability. Each storage unit contains LiFePO4 batteries, known for their high durability – up to 8,000 charging cycles. With its own MPPT controller and an 800 W PV input, the B215 can be easily combined with additional solar modules without complicated wiring. DRBO Greenenergy seamlessly integrates such SunLit energy storage solutions into its portfolio for sustainable energy supply.

• Capacity per module: 2.15 kWh usable

• Maximum expansion: 1 head storage + 3 B215 = 8.6 kWh

• PV input: Up to 800 W per module (MC4 connection)

This flexibility makes the B215 the top choice for tenants in Germany, where tax rates for plug-in solar are 0%.

How does the Sunlit B215 work?

The B215 can be stacked directly on the BK215 head storage unit and connects via plug-and-play with an MPPT input of up to 800 W. Excess energy is efficiently stored, and an app allows real-time monitoring of the storage status. Installation is quick and easy and does not require an electrician.

The functionality of the Sunlit B215 is based on smart technology: The integrated Battery Management System (BMS) protects against overcharging, deep discharge, and temperature fluctuations (from -20 °C to +40 °C). The bypass mode optimizes charging cycles and extends battery life. DRBO Greenenergy offers suitable energy management systems that combine the B215 with inverters like Deye.

Step-by-step guide:

1. Connect BK215 head unit to Schuko socket

2. Stack B215 modules and connect MC4 cables for PV modules

3. Set up app (iOS/Android) for monitoring

What are the technical specifications of the B215?

The Sunlit B215 offers 2.15 kWh capacity, an 800 W PV input, IP65 protection, and operates from -20 °C to +40 °C. The LiFePO4 battery with BMS ensures safety, and the weight per module is approx. 31 kg. The storage unit is expandable up to a PV output of 4 kWp.

Technical highlights make the B215 future-proof: It supports bidirectional inverters and bidirectional charging. DRBO Greenenergy also offers refurbished variants with Deye inverters to ensure maximum efficiency. The SunLit Solar App displays the charge status, yield, and consumption in real time.

Why choose the Sunlit B215?

Choose the B215 for modular expandability, high efficiency, and cost savings – up to 8.6 kWh can cover 70-80% of self-consumption. IP65 protection and app-controlled monitoring ensure reliability, and the 0% tax exemption makes it particularly attractive. DRBO Greenenergy offers fair prices and expert advice for both private and business customers. Compared to fixed installations, the plug-and-play approach saves about €1,000.

• Advantages: Modular, weatherproof, app-controlled

• Disadvantages: Only compatible with BK215

• ROI: Amortization in 2-3 years

How to install the Sunlit B215 expansion storage?

The B215 is simply stacked onto the BK215, MC4 cables are connected to the solar modules, and the storage unit is plugged into a Schuko socket – plug-and-play in just 10 minutes. Electricians are not required, and the app allows for fine-tuning. The IP65 protection allows for use both indoors and outdoors.

Installation is child's play: DRBO Greenenergy supplies suitable accessories such as mounting brackets. Before installation, the socket (Schuko, RCD) should be checked. For maximum PV output, 400 W modules are recommended.

Safety tips:

• Check RCD (Type A or B)

• Observe max. 4 kWp total output

• Perform app updates

Can the B215 be operated in winter?

Yes, the B215 can be operated at -20 °C, thanks to an integrated auxiliary heating system and IP65 protection. The Battery Management System protects the battery from damage due to extreme cold. Efficiency remains high even in winter, and the bypass mode helps extend its lifespan.

Winter suitability: LiFePO4 batteries are stable, and the heating function starts when needed. DRBO Greenenergy recommends placing the storage unit in a protected location. Users report winter efficiency of up to 90%.

What alternatives are there to the SunLit B215?

Alternatives such as Anker Solix or EcoFlow are more expensive and offer less flexibility. The Sunlit B215 stands out with its expandability up to 8.6 kWh. The price-performance ratio is unbeatable, especially with the 0% tax exemption. DRBO Greenenergy offers the Sunlit B215 as the best DIY solution for tenants.

Comparison shows: The B215 is cheaper per kWh. DRBO Greenenergy offers SunLit as an ideal solution for balcony power plants.
