Household energy storage covers three physical forms: wall‑mounted, floor‑standing and stackable, with two architectures of split‑type and all‑in‑one. Wall‑mounted saves floor space, mostly split‑type for small homes with limited expansion. Floor‑standing all‑in‑one delivers large capacity with easy installation for villas and shops. Stackable split‑type offers best expandability for step‑by‑step upgrade for growing power demand.

All‑in‑one is plug‑and‑play for new projects; split‑type provides high compatibility for existing solar retrofit. Three key factors for selection: installation space, present power load and future expansion plan. Choose wall‑mounted for limited space, floor‑standing for easy large‑capacity use, stackable if you plan to increase energy capacity gradually.
