Hybrid Inverter Fox ESS KH8 (8 kW, 1 Phase, High-Voltage)

A premium-class single-phase hybrid inverter (KH series) with an 8 kW capacity. It is an ideal solution for large residential properties with high electricity consumption. Its primary advantages include compatibility with high-voltage (HV) batteries for maximum efficiency and the integration of three independent MPPT trackers, allowing for the optimization of roofs with highly complex layouts.

Advantages:

• High-Voltage (HV) System: Minimizes energy losses, supports rapid charging (up to 50A current), and guarantees enhanced overall efficiency of the solar station.

• 8 kW Power Output (up to 8.8 kW Peak): Effortlessly powers heavy household loads such as heat pumps, electric boilers, air conditioning systems, or electric vehicle (EV) chargers.

• 3 MPPT Controllers (Unique Feature): Enables the connection of solar panels across three distinct roof orientations (e.g., East, South, and West) without compromising overall performance.

• Instant Backup Power (EPS): Automatic and seamless transition to battery power during grid outages or blackouts.

• Advanced FoxCloud Monitoring: User-friendly real-time tracking and control via a dedicated smartphone app (Wi-Fi module included).

• Scalability and Oversizing: Supports solar array configurations up to 12 kW (150% PV oversizing capacity).

Ideal For:

• Private residences with high energy consumption and a single-phase grid connection.

• Properties featuring complex roof architectures where panels must be split across three separate slopes.

• Homeowners seeking a highly powerful, uninterrupted backup power infrastructure.

• Systems designed to optimize grid feed-in ("Green Tariff") and maximize the sale of surplus energy.

Technical Specifications:

• Nominal Output Power: 8 kW

• Max. Solar Array Power: 12 kW (up to 150% PV oversized)

• Phase Layout: 1-Phase (Single-Phase)

• Battery Compatibility: High-Voltage (HV) Li-ion

• Battery Voltage Range: 85–480 V (Recommended: ~300 V)

• Number of MPPT Trackers: 3

• Maximum Efficiency: Up to 97.4%

• Communication Interfaces: Wi-Fi, LAN, RS485

• Ingress Protection Rating: IP65 (Fully dust and waterproof, suitable for outdoor installation)

• Warranty Policy: 10-year standard manufacturer warranty

Explanation of Terms:

• 3 MPPT Trackers – An advanced technology that independently processes energy from three distinct groups of solar panels. If one group is shaded, the remaining two continue operating at peak capacity.

• High-Voltage (HV) Battery – An accumulator system operating at higher voltages, allowing the inverter to manage lower current flows. This directly minimizes cable heat dissipation and substantially increases overall system efficiency.

• EPS (Emergency Power Supply) – A rapid-response backup mechanism that instantly routes battery power to your household loads the moment grid power fails
