Many households with solar‑PV have difficulty determining suitable kWh rating for home battery‑storage. SENJI compiles simple estimation guidance for preliminary reference.
Calculate your household total daily electricity consumption.
Clarify your primary goal: saving bills via peak‑shaving, or grid‑outage emergency backup.
For backup‑power‑oriented scenarios: sum up wattage of critical loads requiring continuous power (fridge, lighting, home‑network devices).
Keep reasonable safety margin and respect LiFePO4 battery DOD limits; avoid full 100% battery depletion.
For balcony‑PV setups and small‑size homes, SJ‑HC‑G wall‑mounted storage is usually sufficient. Villas and high‑consumption households are recommended SJ‑HC‑L / SJ‑HC‑H stacked‑storage for future‑expandable capacity. SENJI engineers deliver precise sizing suggestions based on your electricity bill and solar‑PV installed‑power.
