Total System Value
— (Upon Request)
🛠️Installed Components
- 56 × Sunpal BiMAX5N 440W Bifacial Solar Panels (24.64 kWp)
- 3 × Sunpal SPI-10K Three-Phase Hybrid Inverters (30 kW AC total)
- 4 × Sunpal 48V 200Ah LiFePO₄ Powerwalls (optional / staged)
- 10m Copper Red + 10m Copper Black Solar Cables
- 12 × Solar Wiring & Integration Service Sessions
- Smart EMS Controller with zero-export & priority loads
Three-Phase Design Notes
- Topology: 3 × 10 kW inverters synchronised for 3-phase (400 V, 50 Hz)
- AC Capacity: 30 kW total; DC:AC ratio 0.82 → cooler, reliable
- MPPT Distribution: 56 modules balanced, ~7–10 per string
- Protections: 3-phase AC isolator, DC/AC SPDs, breakers, labels, earthing (IEC)
- EMS: CTs on incomer for zero-export; priority = station ops → EV AC posts → battery
- Compliance: CE, RoHS, international certs; configured for self-consumption (no backfeed)
⚡Energy Benefits
- ~34–38 MWh/year (~95–105 kWh/day), bifacial +5–10%
- ~500–600 km EV driving/day equivalent
- Offsets station loads → lowers OPEX
- Storage-ready for night/cloudy resilience & future peak shaving
- Self-consumption / zero-export hybrid mode
