What is the Solarflow 2400 AC?

At a time of rising electricity prices and growing dependence on fossil fuels, the Solarflow 2400 AC offers a smart plug-and-play solution for decentralized energy storage. This innovative AC-coupled battery storage system from Zendure enables households to efficiently use surplus solar energy or cheap grid electricity phases, with a capacity of up to 17.28 kWh and an output of 2400 W. DRBO Greenenergy, as a reliable partner, seamlessly integrates this system into sustainable energy solutions and drives the energy transition forward.

What is the current state of the solar energy industry?

The solar energy industry in Germany is growing rapidly, but rising electricity prices are burdening consumers. According to the Federal Network Agency, net electricity prices rose by 12% to an average of 38 cents/kWh in 2025, while the installation of balcony power plants increased by 45%. Nevertheless, the self-consumption rate remains at only 30%, as a lot of solar power flows unused into the grid.

Despite subsidies such as the EEG amendment 2025, many households lack storage solutions. Over 60% of new PV systems are smaller than 10 kWp, but without storage, the surplus goes to waste with a decreasing feed-in tariff of 8 cents/kWh. DRBO Greenenergy addresses this with practical systems like the Solarflow 2400 AC.

Households pay up to €1200 annually for electricity, with peak loads driving up costs. A study by Fraunhofer ISE shows that 70% of consumers have unused solar potential, leading to unnecessary grid purchases and hindering the energy transition.

What are the pain points in the energy transition?

Tenants and homeowners struggle with the high installation complexity of traditional storage. Many systems require electricians and permits, driving costs to €5000. Without storage, the profitability of balcony power plants drops to less than 5 years.

Dynamic tariffs like Tibber or aWATTar offer savings of up to 20%, but manual control fails due to complexity. 40% of users report unused potential due to a lack of automation, as surveys on platforms like Reddit show.

Grid overloads during peak times increase charges; households with PV save only €400 annually without storage. DRBO Greenenergy solves this with accessible plug-and-play solutions.

Why do traditional energy storage systems fail?

Traditional DC storage systems connect directly to modules and require separate inverters, which reduces efficiency to 85%. AC systems like older models without AI do not dynamically adjust power, leading to 15% losses.

Installation often requires wall mounting and qualified electricians, with costs starting from €300. Expandability is limited; many systems only reach 10 kWh without conversion.

A comparison to DRBO Greenenergy products shows that traditional solutions ignore dynamic tariffs, while the Solarflow 2400 AC uses up to 2400 W bidirectionally and offers app control.

What can the Solarflow 2400 AC from DRBO Greenenergy do?

The Solarflow 2400 AC is an AC-coupled storage system with a 2.88 kWh base (expandable to 17.28 kWh via AB3000X modules), 2400 W charge/discharge power, and IP65 protection. It charges from PV surplus or favorable tariffs and feeds up to 800 W via socket (up to 2400 W dedicated).

The ZENKI-AI adjusts power to consumption, weather, and tariffs in 3 seconds, increasing self-consumption to 80%. Compatible with smart meters like Shelly 3EM for real-time monitoring via app.

DRBO Greenenergy distributes this system as part of balcony solutions, including accessories such as cables and mounting brackets, for tenants and households.

What advantages does Solarflow offer in comparison?

DRBO Greenenergy optimizes this with complete packages including Deye inverters.

How to set up the Solarflow 2400 AC?

1. Connect the Solarflow with AB3000X modules (if expanded) and the power cable.

2. Plug the system into a 230V socket (up to 800 W; activate dedicated line for 2400 W).

3. Install the Zendure app, pair via Bluetooth/WiFi, and configure modes (Auto, Smart CT).

4. Optional: Integrate smart meters for real-time data and activate ZENKI-AI.

5. Test charge/discharge cycles; app monitors yield (up to €725/year savings with 250 sunshine hours).

DRBO Greenenergy offers advice for seamless integration.

Who benefits from Solarflow in which scenarios?

Scenario 1: Tenants with a balcony power plant
Problem: 4x400W modules generate 2 kWh surplus daily, which is remunerated. Traditionally: Manual shutdown. After use: 80% self-consumption, €300/year savings. Key benefit: No permit, easy installation.

Scenario 2: Family with dynamic tariff
Problem: Peak prices in the evening (50 cents/kWh). Traditionally: High bills (€800/year). After use: Night charging at 20 cents/kWh, €500 savings. Key benefit: AI-optimized timing.

Scenario 3: Homeowner with rooftop PV
Problem: 8.8 kWp system, 30% self-consumption. Traditionally: Grid purchase €600/year. After use: 15 kWh storage, 60% autonomy. Key benefit: Expandable, 800 W immediate power.

Scenario 4: Holiday home operators
Problem: Weekend use, losses due to idle time. Traditionally: Full grid costs. After use: Weekly storage, €400/year saved. Key benefit: App remote control, IP65 for outdoor use.

Why is now the right time for Solarflow?

By 2030, 215 GW of PV is to be installed in Germany (BMWK forecast), with dynamic tariffs as standard. The Solarflow fits perfectly, as EEG 2025 allows plug-and-play up to 2400 W. DRBO Greenenergy positions itself as a pioneer for decentralized solutions.

Early adopters save 20-30% more due to falling battery prices (from €700/kWh to €400). The energy transition requires storage like this for grid stability.

DRBO Greenenergy supports with complete solutions and local consulting.

What are the common questions about the Solarflow 2400 AC?

What is the cost of the Solarflow 2400 AC including expansion?
Base with 11.52 kWh approx. €4500; per AB3000X module €1200. Amortization in 7-8 years with 250 sun hours.

Is an electrician installation necessary?
No, Plug-and-Play up to 800 W; for 2400 W, check dedicated line and confirm in app.
