Why is the SunLit EV3600 the solution for your energy independence?

In an era of rising electricity prices and volatile energy supply, DRBO Greenenergy's SunLit EV3600 offers a bidirectional inverter solution that intelligently extends balcony power plants and storage systems. This inverter enables emergency power supply, grid charging at favorable rates, and high charging capacities of up to 11 kW, allowing households to reduce their electricity costs by up to 50%. DRBO Greenenergy makes this technology accessible and installable for tenants and homeowners alike.

What is the current state of the energy industry?

Germany's energy industry is struggling with a high dependency on fossil fuels and fluctuating electricity prices. According to the Federal Network Agency, electricity prices rose by 12% in 2025 to an average of 38 cents/kWh, while renewable energies only cover 52% of electricity consumption. Many households have self-consumption rates below 30%, leading to unnecessary grid feed-ins.

This situation is exacerbated by seasonal fluctuations: in winter, solar production drops by up to 80%, as shown by data from Fraunhofer ISE. Households with PV systems continue to pay high bills, as storage is often not optimally utilized. The result is additional annual costs of €500–800 per household.

What pain points burden households and businesses?

Tenants and homeowners lack flexible solutions for balconies or carports. Traditional systems do not offer an emergency power function, leading to outages during blackouts – in 2025 alone, there were over 200,000 power outages in Germany (source: VDE). In addition, the lack of bidirectional functions prevents the use of dynamic tariffs, where night electricity is cheaper by up to 20 cents/kWh.

Businesses such as factories or schools struggle with high energy costs, which account for 15–20% of their operating expenses (Statista 2025). Without smart storage, PV surpluses are lost, and e-mobility remains expensive. DRBO Greenenergy addresses this with practical products like the SunLit EV3600.

Why do traditional solutions fail?

Traditional microinverters, such as standard APSystems, only achieve 800 W output and lack bidirectional charging functions. They cannot charge storage from the grid, which pushes self-sufficiency below 20% in winter. Moreover, they often require electrician installations costing €300–500.

Compared to the SunLit EV3600, they offer no modular expandability: maximum power remains stuck at 3.68 kW, without Wallbox compatibility for electric cars. DRBO Greenenergy surpasses this with plug-and-play integration and OTA updates.

What makes the SunLit EV3600 the optimal solution?

The SunLit EV3600 is a bidirectional inverter (3.68 kW output, IP44), compatible with SunLit BK215/B215 storage units. Core functions include grid charging at dynamic tariffs, emergency power via two 230V sockets (up to 2.4 kW), and Wallbox charging up to 11 kW three-phase. DRBO Greenenergy supplies it as a complete package with an 8.6 kWh storage tower.

App control allows local control via DTU and soon Home Assistant integration. Modular expansion to two storage towers doubles capacity to 8.6 kWh. DRBO Greenenergy ensures quality through Deye inverters and a German support team.

What advantage results from the comparison?

When and how to use the SunLit EV3600?

1. Unpack and Check: Unpack the complete DRBO Greenenergy set, connect storage (BK215 + B215) and EV3600.

2. Connection: PV modules to microinverter, storage to EV3600 via DC cable; AC outputs to sockets/Wallbox.

3. App Setup: Download SunLit App, perform OTA update for integration.

4. Configuration: Select charging modes (manual, dynamic, AC-coupled); test emergency power.

5. Operation: Automatic optimization; track self-consumption monthly via app (goal: >70%).

Who benefits in which scenarios?

Scenario 1: Tenant with balcony power plant
Problem: Low winter self-consumption (15%), high bills (€120/month).
Traditional: Surplus to the grid, no storage.
Effect: With EV3600 grid charging at 20 cents/kWh, self-sufficiency to 45%.
Benefits: €450 annual savings, emergency power for refrigerator.

Scenario 2: Family with electric car
Problem: Expensive charging (€0.40/kWh), €300/month.
Traditional: Wallbox without PV use.
Effect: Bidirectional charging with PV/storage, 11 kW peak.
Benefits: €600 savings, V2H for household.

Scenario 3: Small business (workshop)
Problem: High peak loads, outages cost €200/h.
Traditional: Fixed tariffs, no backup.
Effect: Two storage towers, 3.35 kW emergency power.
Benefits: €1,200/year saved, 99% availability.

Scenario 4: Senior apartment
Problem: Blackouts endanger medical devices.
Traditional: No off-grid system.
Effect: EV3600 with 2.4 kW backup, app monitoring.
Benefits: Security, €300 savings, easy operation.

Why is now the crucial time to get started?

By 2030, 15 million balcony power plants are expected to be installed (BMWK forecast), and dynamic tariffs will become standard. The SunLit EV3600 positions users for V2G and smart grids. DRBO Greenenergy is driving the decentralized energy transition – act now for long-term independence.
