DC House – The Sustainable Future of Home Electricity
Leverage direct current (DC) technology powered by solar panels to create highly efficient, off-grid-ready homes and community buildings in Indonesia.
What It Is
The DC House Project developed by EMAT UI and inspired by Prof. Taufik’s research at Cal Poly promotes DC-based electrical systems tailored for modern homes. Using solar PV and DC appliances directly, this setup eliminates AC–DC conversion losses and dramatically improves energy efficiency. It’s simpler, greener, and built for future-ready living.
How It Works
Solar Energy + Battery Storage Powers Efficient, Off-Grid Cold Storage in Coastal Communities
Solar + Battery Hybrid Design
Solar PV generates power to run the refrigeration unit directly during the day; excess energy is stored in batteries to maintain cooling overnight or during cloudy periods.
Miniaturized Cold Storage Capacity
Engineered for on‑boat or onshore use, optimized for small-volume fish preservation—typically up to 300 kg—while maintaining temperatures near 0 °C
Energy-Efficient Operation
With total power requirements under 500‑700 W and high COP design, the system reduces electricity consumption while maximizing reliability.
Target Use Cases
Solar Energy + Battery Storage Powers Efficient, Off-Grid Cold Storage in Coastal Communities
Artisanal Fishermen
Preserve catch quality and extend market range
Coastal Communities
Self-managed cold chain without electricity or ice
Emergency Response
Temporary cold storage in flood or disaster zones
Use Cases & Applications
Emergency Water Supply
Ideal during floods or disaster relief: a reliable, fuel-free water source when electricity is unavailable.
Agriculture & Irrigation
Perfect for remote farms or fields near wells or surface water, enabling irrigation without diesel or grid power
General Water Access
Suitable for livestock watering, community wells, and off-grid households.
Benefits at a Glance
Showcase core services with icons or cards in clean layout inspired by Arcurve’s simplicity
Lower Operating Costs
Eliminates daily ice purchases; up to 30% savings for fisherfolk.
