Residential Dual Hybrid · Bau, Sarawak

Phase 1 — Core home system: dual Sunpal hybrid inverters (single-phase) with rooftop BiMAX bifacial PV, tidy 4 mm² solar/DC cabling and Hager MCB / DB protection.

Phase 2 — Storage & failover: wall-mounted Sunpal LiFePO₄ Powerwall 200Ah with ATS so essential loads stay up when the grid drops.

Phase 3 — Expansion (23 Aug 2025): +12 PV panels with mounting rails, balanced into the existing dual-hybrid MPPT strings for more daytime harvest.
