System components
Required components
EcoFlow OCEAN 2 LFP Battery 5.02 kWh (BD-5-S2)
Item number: DLK-ECOFLOW-EFBD5S2
The OCEAN 2 is a battery-based system: at least one OCEAN 2 LFP module is required for storage, backup and HEMS operation. Each 5.02 kWh module (4.85 kWh usable) delivers 3.4 kW discharge / 2.5 kW charge and stacks wire-free under the inverter.
EcoFlow OCEAN 2 LFP Battery Base
Item number: DLK-ECOFLOW-OCEAN2-BASE
Every floor-standing battery tower sits on the OCEAN 2 battery base with adjustable levelling feet, spirit level and click-on stacking terminal, the standard mounting for up to 6 modules per stack (wall mounting up to 3 modules uses wall brackets instead).
Recommended components
EcoFlow OCEAN 2 LFP Battery 8 kWh (BD-8-S2)
Item number: DLK-ECOFLOW-EFBD8S2
The larger 8 kWh module reaches higher capacity in fewer stacking steps, same tower format, up to 6 per floor stack and 12 modules per OCEAN 2 Plus inverter per EcoFlow's compatibility matrix.
EcoFlow Smart Meter (external grid-point meter)
Item number: DLK-ECOFLOW-SMART-METER
Only needed when not all household loads are wired behind the backup output: the external meter then provides the grid import/export measurement the HEMS needs for self-consumption optimisation and export limiting. In the standard whole-home-backup topology the built-in meter covers this.
Optional components
EcoFlow Battery Junction Box
Item number: DLK-ECOFLOW-EFBDJCS1
For multi-tower installations: cascaded battery stacks connect through a junction box (built-in 1500 V DC / 32 A fuse, battery switch, B-COM port); up to 3 junction boxes can run in parallel. Not needed for a single integrated stack under the inverter. Confirm the OCEAN 2-compatible junction-box variant when ordering.
EcoFlow Battery Stack Bridge
Item number: DLK-ECOFLOW-STACK-BRIDGE
Bracket for dual-tower battery systems: rigidly ties two adjacent towers together (base spacing 94.6-104.5 mm for OCEAN 2 bases). EcoFlow recommends securing both sides of each battery unit, 12 brackets for two 6-module towers, and seismic restraint in seismic zones.
EcoFlow PowerOcean LFP Battery 5.1 kWh (BD-5.1-S1, gen 1)
Item number: DLK-ECOFLOW-EFBD51S1
Cross-generation expansion path: existing PowerOcean gen-1 packs can be mixed with OCEAN 2 packs in one system (max 4 modules per stack in mixed use per the matrix), useful when extending a gen-1 install instead of replacing it.
Approved pairings
