Deye Balcony Battery Expansion Pack AE-F2.0 (for Balcony Micro ESS AE-FS2.0 2H2)

Running out of stored solar energy by 9 PM? Add an AE-F2.0 and double your capacity to 4kWh — enough to power your evening TV, lights, and router entirely from solar. The module stacks right next to your main unit and connects with a single cable. No tools, no electrician, no downtime.

Built with LiFePO4 chemistry — the safest, longest-lasting lithium technology available. Rated for over 6,000 charge cycles at 70% capacity retention, that’s more than 16 years of daily use. Even if you move apartments, this battery will still be going strong.

Just like the main unit, the AE-F2.0 is built for the outdoors. IP65 weatherproofing keeps it safe from rain, dust, and humidity. The built-in BMS (Battery Management System) monitors every cell for temperature, voltage, and current — protecting both the battery and your home.

Start with one expansion pack when your needs grow, add more later. Connect up to 4 AE-F2.0 modules in parallel with your AE-FS2.0-2H2 main unit for a total of 10kWh — enough to store an entire day’s solar production. Each module adds capacity without changing how the system works.
