Description

11,000 W solar intake with direct high-voltage storage coupling.

EcoFlow EF HD-P1-5K-S1 is a 5 kW single-phase residential hybrid inverter delivering up to 11 kWp solar intake across dual high-current MPPT channels, engineered to stack cable-free atop EcoFlow PowerOcean high-voltage 5 kWh battery packs.

EcoFlow EF HD-P1-5K-S1
  • 11,000 Wp High-Ratio Solar Intake (220% DC)

    Double solar intake ensures rapid battery charging and daytime domestic self-consumption even on overcast winter days.

  • 5,000 W Continuous AC & Backup Output (22.7 A)

    Easily runs cooking appliances, refrigerators, and domestic circuits during utility blackouts.

  • Direct 800 V High-Voltage Battery Interface

    Direct DC coupling to PowerOcean 5 kWh packs eliminates step-up conversion losses.

  • Dual High-Current MPPT Trackers (18 A / 16 A), 100% compatible with modern 500W+ residential modules without current clipping.

More product details

Modern residential homes demand high solar absorption to charge batteries and power appliances on cloudy winter days. The HD-P1-5K-S1 accepts up to 11 kWp DC input, pushing surplus solar directly into storage across an 800 V window.

  • Dual MPPT channels (18 A single / 16 A dual) optimize East/West roof pitches down to 90 V startup.
  • 800 V DC battery architecture eliminates step-up voltage boost losses during battery charging.
  • Wide MPPT window (90–520 V) optimizes harvest across extreme temperature swings.
