Dual Hybrid Solar with Battery & ATS — Bau, Sarawak
A Bau home powered by single-phase dual hybrid inverters, a wall-mounted Sunpal LiFePO₄ Powerwall 200Ah and ATS failover — later expanded with +12 PV panels.
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.
