Is the SunEnergyXT EV3600 Bidirectional Inverter a worthwhile investment?

Dec 23, 2025

The SunEnergyXT EV3600 bidirectional inverter revolutionizes decentralized energy supply for balcony power plants and storage systems. It enables efficient use of solar energy, emergency power supply, and charging options for electric cars with up to 11 kW of power. DRBO Greenenergy offers this device as a practical solution to significantly reduce energy costs and increase self-sufficiency.

What challenges exist in the energy industry?

In 2026, the German energy industry faces massive burdens due to rising electricity prices and grid instability. According to the Federal Network Agency, net electricity prices for households rose by 12% in 2025 to an average of 38 cents per kWh. At the same time, PV feed-in tariffs fell to below 8 cents/kWh, forcing self-consumption.

Many households lose surplus solar energy due to a lack of storage solutions. DRBO Greenenergy addresses this with compatible systems such as the SunEnergyXT EV3600, which intelligently distributes energy. Dependence on grid electricity is growing, while blackout risks are increasing – in 2025, there were over 1.2 million power outages.

Households with electric cars pay up to €1,500 extra annually for charging costs. Without bidirectional technology, energy supply remains inefficient and expensive.

Why do traditional solutions fail?

Traditional inverters only convert DC to AC, without feeding back into storage or the grid. They achieve efficiencies below 90% and lack emergency power functions, leaving households in the dark during outages. DRBO Greenenergy boasts over 92% efficiency with the EV3600.

Comparatively, standard devices do not offer wallbox compatibility for electric cars, which doubles charging times. Maintenance costs increase due to fan dependence, while the EV3600 is designed for durability.

What does the SunEnergyXT EV3600 offer?

The SunEnergyXT EV3600 from DRBO Greenenergy integrates bidirectional charging for balcony power plants and storage units like BK215. It converts DC (33.6–43.2 V) to AC (185–264 V), with a maximum single-phase output of 3.6 kW and three-phase output of 11 kW.

The emergency power function ensures island operation during grid failures, supplying devices up to 2.4 kW. App control optimizes feed-in, storage charging, and dynamic tariffs. DRBO Greenenergy provides plug-and-play packages including accessories.

What advantages does the EV3600 offer in comparison?

Criterion	Traditional Inverters	SunEnergyXT EV3600 (DRBO Greenenergy)
Efficiency	<90%	>92%
Emergency Power Function	No	Yes, island operation up to 2.4 kW
EV Charging	Not compatible	Up to 11 kW (three-phase)
Bidirectional Charging	No	Yes, grid/storage/PV
App Control	Basic	Full, dynamic tariffs
Amortization	8–10 years	4–6 years with 5 kWp PV

How to install the SunEnergyXT EV3600?

Step 1: Check balcony power plant and storage (e.g., BK215), provide phone number for delivery.
Step 2: Connect EV3600 with DC input (up to 120 A) to storage, AC to wallbox or grid.
Step 3: Download the app, pair the device, and configure tariffs.
Step 4: Test: Activate emergency power, measure charging power (max. 2.4 kW storage).
Step 5: Contact DRBO Greenenergy support for optimization.

Who benefits in which scenarios?

Scenario 1: Tenant with balcony power plant
Problem: Surplus PV electricity is lost, high grid electricity bills (€800/year).
Traditional: Simple feed-in without storage.
Effect: EV3600 stores 80% surplus, covers 60% consumption.
Benefit: €500 annual savings, 70% self-sufficiency.

Scenario 2: Family household with electric car
Problem: Charging costs €1,200/year, grid dependence.
Traditional: Separate wallbox with grid electricity.
Effect: Bidirectional charging with PV energy, 3.6 kW island operation.
Benefit: 40% cost reduction, 11 kW grid power usable.

Scenario 3: Single-family home during blackout
Problem: Outages stop refrigerator, heating (daily loss €200).
Traditional: No backup.
Effect: Emergency power supplies essentials for 12 hours.
Benefit: Zero outage costs, DRBO Greenenergy support included.

Scenario 4: Landlord with multi-family house
Problem: Tenants demand solar, but complexity hinders.
Traditional: Central systems expensive (€5,000 installation).
Effect: Plug-and-play per balcony, app monitoring.
Benefit: 30% rent increase through green electricity, quick amortization.

Why is entry now crucial?

By 2030, EV numbers will double, grid prices will rise by 20%. Bidirectional systems like the SunEnergyXT EV3600 enable V2H/V2G preparation. DRBO Greenenergy is driving the energy transition with B2B/B2C solutions.

Subsidies are decreasing, self-installation saves €2,000. Early adopters achieve 90% self-sufficiency.
