Deye SUN-BK250-2.56KWH-EU-AM4-32L All-in-One Hybrid System 2.5kW 2.56kWh
The Deye SUN-BK250-2.56KWH-EU-AM4-32L is an all-in-one micro storage system that packs a 2500W single-phase hybrid inverter and a 2.56kWh LiFePO4 battery into one IP65 body. It is made for balconies, terraces, small roofs and holiday homes: it plugs into a household socket, stores the surplus from the panels and gives it back in the evening, working both on-grid and off-grid with ≤ 4 ms switchover.
It accepts up to 5760W of PV on 4 independent MPPTs, so four panels with different tilts and orientations can be used without mismatch losses. The system is scalable: up to 3 inverters in parallel (7.5kW) and 5 stacked batteries (12.8kWh) per cluster, up to 102.4kWh in a full configuration. Monitoring and control over Wi-Fi, Bluetooth and LoRa with the Deye Cloud app, ≥ 6000 cycles and a 10-year warranty.
Key features
Inverter and battery in one bodyA single 30 kg IP65 unit holds a 2500W hybrid inverter and a 2.56kWh LiFePO4 battery: no DC wiring to size.
4 MPPTs for 4 panelsFour independent trackers with a 20-55V range accept up to 5760W in total, even with panels facing different ways.
Backup in ≤ 4 msSwitchover between grid and island mode takes 4 milliseconds, so connected loads never notice the transition.
Scalable to 102.4kWhUp to 3 inverters in parallel and 5 stacked batteries per cluster, up to 8 clusters and 40 batteries at full build-out.
