Rooftop Solar PV (DC Generation)Hybrid Storage Inverter & Home BESS (15 kWh)Home Distribution, EV Charger & Grid IntertieEnd-to-End Residential Solar & Storage Ecosystem: ① High-efficiency bifacial N-type TOPCon modules convert incident solar irradiance into direct current (DC); ② Direct current is routed via weather-resistant DC cabling to the wall-mounted hybrid inverter, where high-speed MPPT tracks the maximum power point and performs pure sine-wave DC-to-AC conversion (220V/110V, 50Hz); ③ Excess green energy is automatically stored in the PowerVault lithium iron phosphate (LFP) battery bank (15 kWh); ④ The smart distribution panel intelligently allocates power to home appliances (heat pumps, refrigeration, LED lighting, and EV chargers); ⑤ Surplus electricity is exported to the public utility grid for revenue, while sub-10ms EPS automatic transfer switches ensure uninterrupted emergency backup during outages.

STEP 01 // ROOFTOP PHOTOVOLTAIC ARRAY

Solar Irradiance ➔ Direct Current (DC)

Incident photons excite electrons in N-type TOPCon monocrystalline cells, producing high-voltage DC power routed through fire-rated conduits and surge-protected junction boxes.

P_dc = G · A · η_pv (Peak 8.0 kW)

STEP 02 // HYBRID STORAGE INVERTER

Dual MPPT Tracking & DC-AC Conversion

Wall-mounted hybrid inverter executes sub-second Maximum Power Point Tracking (MPPT), converting fluctuating DC inputs into grid-compliant pure sine wave AC (220V/50Hz).

STEP 03 // RESIDENTIAL BATTERY (BESS)

PowerVault 15 kWh LFP Storage

Midday surplus green electricity charges automotive-grade LFP cells. During evening peak tariff hours, power discharges to eliminate utility draw; upon grid failure, EPS transfers in <10ms.

STEP 04 // SMART DISTRIBUTION & GRID

Whole-Home Loads, EV Charger & Net Metering

Smart distribution panel prioritizes HVAC heat pumps, household refrigeration, and a 7kW Level-2 EV charger, feeding surplus electricity into the utility grid for feed-in tariffs.

Aerodynamic Lift (FL) Driving Rotor RotationSpeed-Increasing Gearbox (Planetary + Parallel 1:125)DFIG / PMSG Generator & Full-Scale ConverterAerodynamic and Mechanical Power Conversion: Wind flows across aerodynamic NACA airfoil blades, creating a differential pressure gradient that generates perpendicular lift (FL). This tangential force drives the low-speed main shaft (8–16 RPM). A multi-stage planetary and helical gearbox increases angular velocity by 125x (up to 1,500 RPM) to drive the generator rotor. Electromagnetic induction generates high-efficiency AC power, synchronized to 50 Hz grid frequency via back-to-back IGBT power converters.

STEP 01 // AERODYNAMIC LIFT

Betz Limit & Airfoil Lift Decomposition

Airflow across specialized NACA airfoil blades creates differential Bernoulli pressure, resulting in an upward aerodynamic lift vector (FL). Its tangential component drives the rotor hub at low angular velocity (8–16 RPM).

P_wind = 0.5 · ρ · A · v³ · Cp (Cp,max ≤ 16/27 ≈ 0.593)

STEP 02 // MECHANICAL DRIVETRAIN

Multi-Stage Planetary Gearbox (1:125 Ratio)

The forged alloy main shaft transfers high-torque rotation from the multi-ton rotor through spherical roller bearings into a compound planetary gearbox, stepping up rotor speed to the generator's rated 1,500 RPM.

n_gen = n_rotor · i_total ≈ 1,500 RPM

STEP 03 // ELECTROMAGNETIC CONVERSION

DFIG / PMSG Generator & 4-Quadrant Inverter

Rotor copper windings sweep stator magnetic fields at high velocity, inducing 3-phase AC electromotive force. Full-power back-to-back IGBT converters condition voltage and phase angle for strict 50.00 Hz grid synchronization.
