Description
6,000 W solar intake with direct high-voltage storage coupling.
EcoFlow EF HD-P1-3K-S1 is a 3 kW single-phase residential hybrid inverter delivering 200% DC oversizing (6 kWp solar intake) across dual 16 A MPPT channels, engineered to stack cable-free atop EcoFlow PowerOcean high-voltage 5 kWh battery packs.
200% High-Ratio PV Oversizing (6,000 Wp)
Channels substantial solar generation from small residential arrays into daytime loads and high-voltage 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.
Integrated Automatic Backup Transfer (< 20 ms)
Keeps critical domestic refrigeration, lighting, and Wi-Fi powered during utility grid blackouts.
More product details
Compact single-phase homes often have limited roof area but high demand for winter solar capture. The HD-P1-3K-S1 accepts double its rated AC capacity in solar DC input, pushing surplus generation into storage.
- Dual 16 A MPPT channels optimize East/West roof pitches down to low startup thresholds.
- 800 V DC battery architecture eliminates step-up voltage boost losses during battery charging.
- 97.2% European efficiency minimizes internal heat dissipation under continuous full-load operation.
