Floor‑standing batteries are placed directly on flat ground, mostly all‑in‑one integrated units. Battery, inverter and BMS are housed in one vertical cabinet with typical capacity of 15‑30kWh, targeting large houses, villas and small shops. Pre‑commissioned in factory, it supports grid‑tie, off‑grid and peak‑valley arbitrage modes after simple connection with solar and grid power.

Integrated design ensures stable system matching and easy maintenance without complicated component matching. Drawbacks include required floor area and heavy weight for inconvenient relocation. It is suitable for families and small businesses pursuing plug‑and‑play reliability with large backup power demand.
