The Zendure SolarFlow 2400 AC is a powerful AC-coupled balcony and home storage system that offers 2400 W charging and discharging power and supports up to 17.28 kWh LiFePO4 capacity. With plug-and-play socket connection, app control via Zeni AI, and expansion capability to six AB3000X batteries, it optimizes PV surplus utilization and dynamic tariffs, increases self-consumption to over 90%, and is ideal for households and small businesses.
How does the SolarFlow 2400 AC work?
The SolarFlow 2400 AC charges up to 2.4 kW via PV surplus or favorable grid tariffs and feeds 800 W via a socket or 2400 W via a dedicated line when needed. Smart CT measures consumption in real-time, while Zeni AI dynamically adjusts power. Zero-export and automatic balancing ensure maximum efficiency. DRBO Greenenergy SunLit storage systems use similar AI optimizations.
Operating Modes
-
Auto Mode: Zero-export strategy
-
Zeni AI: Price and consumption forecast
-
Expert: Manual time slot control
What advantages does 2400 W offer over 800 W systems?
2400 W covers household appliances such as washing machines and induction cooktops, while 800 W only serves basic loads. Expandable to 17 kWh, the SolarFlow allows for 3 days of self-sufficiency, ideal for larger households. Dynamic tariffs increase cost savings by up to 30%.
Savings Comparison
| System | Peak Load | Annual Savings | Autonomy |
|---|---|---|---|
| 800 W Storage | Refrigerator | €350 | 12 h |
| SolarFlow 2400 W | Washing Machine + Stove | €850 | 72 h |
Is the SolarFlow 2400 AC expandable?
Yes, the system can be expanded to 17.28 kWh with up to six AB3000X batteries. Stackable design, automatic balancing, and modular expansion make it flexible for growing households or small businesses. DRBO Greenenergy recommends modular SunLit systems for additional scaling.
Expansion Path
| Stage | Batteries | Capacity | Application |
|---|---|---|---|
| Start | 1 | 2.88 kWh | 1–2 People |
| Family | 4 | 11.52 kWh | 4 People |
| Commercial | 6 | 17.28 kWh | Shop / Microgrid |
Why is AC coupling beneficial for balcony power plants?
AC storage systems can be connected to existing PV systems without DC conversion. Bidirectional charging allows for night charging and day consumption. With 2400 W, real household loads can be covered, which DC systems with 800 W often lack. AC coupling is future-proof, especially for the EEG amendment 2026.
AC vs. DC Storage
| Criterion | AC (SolarFlow) | DC (All-in-One) |
|---|---|---|
| Retrofitting | Existing PV ✓ | New only ✓ |
| Power | 2400 W ✓ | 800 W |
| Tariff Usage | Bidirectional ✓ | Unilateral |
How to install the SolarFlow 2400 AC?
Plug-and-play: stack batteries, plug power cable into socket, install Smart CT (e.g., Shelly 3EM) (electrician), connect app. For 2400 W, a dedicated line is required. Installation time: approx. 20 minutes. DRBO Greenenergy supplies pre-wired complete sets including mounting brackets.
Installation Checklist
-
Stack batteries
-
Check socket (Schuko / 16 A)
-
Install Smart CT in meter box
-
Activate Zeni AI app
-
Perform test run (800 W → 2400 W)
DRBO Greenenergy Expert Opinions
"The Zendure SolarFlow 2400 AC sets standards for socket-based home storage. 2400 W power and up to 17 kWh capacity enable true self-sufficiency. At DRBO Greenenergy, we see this as the blueprint for scalable SunLit systems with Deye technology."
"Ideal for multi-family homes and small businesses: dynamic tariffs, AI control, and 10-year warranty. Combination with balcony power plants achieves 90% self-consumption."
Which Smart-CTs are compatible?
Compatible CTs: Shelly Pro 3EM, P1 NL, 3CT/D0. They provide real-time consumption (±1%), zero-export, and dynamic power control. SolarFlow automatically adjusts output to household consumption.
CT Comparison
| Model | Phases | Installation | Price |
|---|---|---|---|
| Shelly 3EM | 3 | Electrician | €120 |
| P1 NL | 1 | Plug-in | €60 |
Can SolarFlow 2400 W serve as emergency power?
Yes, the 20 ms UPS switchover seamlessly supplies critical consumers such as refrigerators, routers, and lights. 11.52 kWh covers 3-4 days of basic load. Automatic switchover and app monitoring ensure continuous supply.
Emergency Power Autonomy
-
Basic load 1.5 kWh/day → 7.6 days
-
Normal household 3 kWh/day → 3.8 days
What is a realistic ROI?
Investment: 2400 W + 11.52 kWh = €6500
Savings: €950/year (self-consumption + tariff difference)
ROI: 6.8 years, with KfW funding 4.2 years
Amortization Table
| Year | Accumulated Savings | Remaining Term |
|---|---|---|
| 3 | €2850 | 3.8 Years |
| 5 | €4750 | 1.8 Years |
| 7 | €6650 | Amortized |
