The FoxESS P3-SH is a robust three-phase hybrid inverter designed to maximize self-consumption, shave peaks, and provide fast emergency power (EPS). It pairs with FoxESS high-voltage LiFePO₄ batteries and supports generous PV oversizing with multiple independent MPPTs—all inside an IP65 outdoor-rated enclosure with silent, natural convection cooling and FoxCloud remote monitoring. 

Key benefits

• High-voltage storage, high efficiency: Works with FoxESS HV LFP batteries (100–800 V) and delivers European efficiency up to ~97.9%.

• Serious PV flexibility: Up to 3 independent MPPTs (model-dependent) with wide 120–950 V MPPT range and 1000 V max PV input—ideal for complex roofs and array orientations.

• Fast backup (EPS): Automatic switchover to EPS in under 20 ms to keep essential loads powered during grid outages (three-phase 400/230 V). Battery required for EPS.

• Outdoor-ready & quiet: IP65 protection, natural cooling (no noisy internal fans on 8–10 kW models).

• Smart monitoring & comms: FoxCloud V2.0 app/portal with Ethernet, WiFi/LAN (WiLAN), RS485/EMS, CAN (BMS), optional 4G, and meter support.

• Built-in safety: Type II SPD (DC/AC), anti-islanding, insulation & leakage current monitoring; AFCI available.

• Time-of-use and peak-shaving strategies

• Whole-home or critical-load backup (EPS) with compatible HV batteries

• Small commercial and larger residential three-phase systems

Installation notes

• Three-phase 400/230 V (3L/N/PE) grid and EPS outputs.

• EPS operation requires a FoxESS-compatible HV battery and a dedicated essential-loads sub-board/ATS.

• Supports external energy meter via RS485 for export limiting and advanced control.

• Natural-convection cooling on 8–10 kW; outdoor wall-mount (IP65).

• Standard 10-year warranty.
