In an era of rising energy prices and growing reliance on renewable energies, bidirectional inverters with WLAN monitoring and app offer an efficient solution for households. These systems maximize the self-consumption of solar power, enable intelligent energy management, and reduce electricity costs by up to 70 percent in the long term. DRBO Greenenergy positions itself as a reliable partner with practical solutions for tenants and homeowners.
What are the current challenges in the energy transition industry?
The private energy sector struggles with volatile electricity prices and untapped solar potential. According to the Federal Ministry for the Environment, electricity prices rose by 12 percent in 2025 to an average of 42 cents per kWh, while only 40 percent of the generated solar power is consumed in the household. Households lose thousands of euros annually due to feed-in tariffs that are below grid purchase costs.
Many families are affected by grid fluctuations, especially in regions with a high proportion of PV. The German Energy Agency (dena) reports that 65 percent of households without storage do not optimally utilize their solar system, leading to peak loads and higher bills. Reliance on grid electricity also unnecessarily increases CO2 emissions.
Why do traditional solutions lack crucial functions?
Traditional inverters only convert solar power unidirectionally and ignore storage integration. They achieve efficiencies of a maximum of 90 percent without bidirectional control, leading to 20-30 percent energy losses. Without app monitoring, real-time transparency is missing, and installations often require electricians, with costs starting from 500 euros.
In comparison, conventional systems do not offer WLAN connectivity, forcing manual checks. DRBO Greenenergy stands out with integrated SunLit storage units and Deye inverters, which enable plug-and-play installations with app control. Traditional devices fail with dynamic tariffs as they do not support automatic charging/discharging cycles.
What characterizes bidirectional inverters with WLAN and app?
Bidirectional inverters like the EV3600 from DRBO Greenenergy convert DC to AC and vice versa, with efficiencies up to 98 percent. They integrate WLAN modules for app monitoring, which provides real-time data on yield, storage status, and consumption. Compatible with balcony power plants and microgrids, they support up to 3.6 kW charging power and vehicle-to-home functions.
The app enables remote control, forecasts based on weather data, and integration into smart home systems via Modbus or MQTT. DRBO Greenenergy combines these with storage units up to 8.6 kWh, including backup in case of grid failures. Certifications such as VDE and CE ensure 10 years of longevity.
What advantages do bidirectional systems offer compared to traditional ones?
| Criterion | Traditional Inverters | Bidirectional Inverters (DRBO Greenenergy) |
|---|---|---|
| Efficiency | 85-90% | 92-98% |
| Energy Flow | Unidirectional (DC to AC) | Bidirectional (AC/DC) |
| Monitoring | None or local | WLAN/App Real-time |
| Self-consumption | 40-50% | Up to 80-90% |
| Installation Costs | €500-1000 (Electrician) | €0-200 (Plug-and-Play) |
| Smart Home Integration | No | Yes (Modbus, MQTT) |
This table shows measurable efficiency gains, reflected in amortisation periods of under 3 years.
How to install and use the system step by step?
-
Step 1: Connect solar modules and storage (e.g., SunLit BK215) to the EV3600 inverter via plug-and-play – takes 30 minutes.
-
Step 2: Set up WLAN connection via app, scan network, and configure device.
-
Step 3: Adjust app dashboard for charging times, tariff optimization, and consumption limits.
-
Step 4: Test the system – track yield and update firmware if necessary.
-
Step 5: Analyze monthly reports to increase self-consumption to over 80 percent.
DRBO Greenenergy offers video tutorials for error-free commissioning.
Who benefits from the solution in which scenarios?
Scenario 1: Tenant with balcony power plant
Problem: Low self-consumption during the day, high evening tariffs. Traditionally: Surplus fed into the grid at 8 cents/kWh. After implementation: Storage charges during the day, discharges in the evening – yield increases by 60 percent. Key benefit: Annual savings of 450 euros.
Scenario 2: Family with electric car
Problem: High charging costs with dynamic tariffs. Traditionally: Night charging from the grid. After implementation: Bidirectional charging with solar surplus – 3.6 kW wallbox integrated. Key benefit: Monthly reduction of 120 euros.
Scenario 3: Homeowner with heat pump
Problem: Peak loads in winter. Traditionally: Grid purchase expensive. After implementation: App-optimized load management, targeted storage discharge. Key benefit: 25 percent lower heating costs.
Scenario 4: Holiday home owner
Problem: Power outages, no monitoring. Traditionally: Manual checks. After implementation: Remote access via app, backup mode. Key benefit: 100 percent autonomy for 8 hours.
Why is now the right time to get started?
The energy transition is accelerating with EU targets of 45 percent renewable energy share by 2030. Bidirectional systems are compatible with V2G standards and AI-supported management. DRBO Greenenergy prepares for these trends with upgradable solutions, ensures amortization in 2-4 years, and maximizes independence.
