Description
Maximizing single-phase export beneath regulatory unbalance ceilings.
EcoFlow EF HD-P1-4.6K-S1 is a 4.6 kW single-phase residential hybrid inverter delivering 200% DC oversizing (9.2 kWp solar intake) and a certified 4.6 kVA / 20.0 A AC export cap, engineered to comply precisely with German VDE-AR-N 4105 single-phase unbalance limits.
4.6 kVA / 20.0 A Single-Phase Phase-Unbalance Cap
Exactly matches the maximum allowable single-phase generation limit under German VDE-AR-N 4105 and European grid codes.
9,200 Wp High-Ratio Solar Intake (200% DC)
Channels abundant rooftop solar generation into daytime home loads and high-voltage PowerOcean storage.
Direct 800 V High-Voltage Battery Interface
Direct DC coupling to PowerOcean 5 kWh packs eliminates step-up conversion losses.
Dual 16 A High-Current MPPT Trackers, 100% compatible with modern 500W+ residential modules without current clipping.
More product details
In Germany and parts of Europe, single-phase grid feeding is legally capped at 4.6 kVA to prevent grid phase-imbalance. The HD-P1-4.6K-S1 is factory-certified at 4,600 VA, allowing maximum allowable solar generation while remaining fully compliant.
- Factory firmware limits continuous apparent power to 4,600 VA (20.0 A @ 230 V).
- Connects up to 9,200 W of rooftop solar, routing generation above 4.6 kW directly into high-voltage storage.
- Dual 16 A MPPT channels optimize East/West roof pitches down to low startup thresholds.

EcoFlow PowerOcean Single-phase datasheet (EU, EN)Product questions
Why choose the 4.6 kW model over the 5 kW model in Germany?
German grid code VDE-AR-N 4105 caps single-phase export at 4.6 kVA. Installing a 5 kW inverter on a single-phase German grid connection requires either a software power export limit certificate or utility rejection. The HD-P1-4.6K-S1 carries native 4.6 kVA factory certification, streamlining local grid interconnection approval.
