Deye ALL-IN-ONE system 2 x AE-FS2.0-2H2/7 (4kWh)

The configuration consists of two identical devices, each of them a complete system: it collects energy from the panels, converts it into socket current and stores it in its own battery. By doubling up you get both a reserve twice as large and double the output power. Being two separate units, you can place them in different locations and connect them to different circuits, which means that a failure or a shutdown does not leave everything without supply.

Together, the two units store 4 kWh and deliver 2 x 800 W, and at peak 2 x 1000 W. As a guide, at a permanent consumption of 400 W, the 4 kWh cover approximately 10 hours, so a whole night for the baseline loads. Each unit accepts up to 2200 W of panels on two separate inputs, so you can orient the groups differently, for production spread across the whole day. Both have a UPS function, switching to battery in under 4 ms, and USB-A and USB-C ports. Each enclosure measures 450 x 210 x 321 mm, about 26 kg and has IP65 protection, so they can stay outdoors, and each can be expanded separately up to 10 kWh with AE-F2.0 modules.

Per unit: two MPPT inputs in the 20-60 V range, maximum 15 A per channel, MPPT power 1000 W, maximum panel power 2200 W; AC output 800 W continuous and 1000 W peak, at 220/230 V and 50/60 Hz, through a standard socket, UPS switching under 4 ms. LiFePO4 batteries of 2,0 kWh at 51,2 V nominal, over 6000 cycles with 70% residual capacity at end of life, expandable to 10 kWh per unit with AE-F2.0 modules. IP65 enclosure, 450 x 210 x 321 mm, approx. 26 kg per unit, operation -10...+50 °C, configuration and monitoring via WiFi and Bluetooth. Warranty: 10 years battery / 5 years inverter, per unit.

Who it suits

Suitable for an apartment or a home with two sunny areas for placing the panels, which wants a reserve sufficient for a whole night and prefers two independent devices instead of a single one.

Terms explained

• Independent units: The two devices work separately, each with its own panels and battery; if one is switched off or moved, the other keeps supplying power.
• Peak power (1000 W): The extra power the device can deliver for a short time, when starting a motor or a fridge compressor.
• 70% capacity at end of life: After more than 6000 full charges, the battery still retains about 70% of the initial energy; it does not stop, it just lasts less.

Technical specifications

Recommended applications

• Balcony systems with doubled storage, for longer autonomy
• Self-consumption in apartments and homes with two panel placement areas
• Backup for small loads, distributed over two independent circuits
• Modular solution, later expandable with AE-F2.0 battery modules

Warranty

10 years battery / 5 years inverter (per unit)

Technical details

Series-level specifications — valid for the product family

The 4 kWh configuration is made up of two Deye AE-FS2.0-2H2 units, each a complete all-in-one system integrating the photovoltaic MPPT input, the bidirectional AC/DC converter and a LiFePO4 battery of 2,0 kWh at 51,2 V nominal. By doubling the unit you obtain a total reserve of 4 kWh and double the output power compared with a single unit.

Each unit has two MPPT inputs with a 20-60 V range and a maximum current of 15 A per channel, an MPPT power of 1000 W and a maximum accepted panel power of 2200 W. The AC output is 800 W continuous, with a peak of 1000 W, at 220/230 V and 50/60 Hz, the connection being made through a standard socket. The UPS function switches in less than 4 ms when the grid fails, and the USB-A and USB-C ports allow direct powering of small devices.

Each enclosure measures 450 x 210 x 321 mm and weighs approximately 26 kg, with IP65 protection rating and an operating range of -10...+50 °C, so both units can be placed outdoors. Configuration and monitoring are done from the mobile app via WiFi and Bluetooth. The batteries have over 6000 cycles with 70% residual capacity at end of life, and each unit can be expanded individually up to 10 kWh with AE-F2.0 modules.
