Key facts
- DC round-trip efficiency at rated power ≥94.5% (EN site); Chinese site lists 95% (0.5C) and 96.5% (0.25C)
- Rated power in kW not published; only maximum charge/discharge rate 0.5C or 0.25C per cell option
- Dual refrigeration mode (compressor and natural cooling); press release claims temperature spread <2.5 °C
- Noise ~85 dB(A) at 1 m, 70 dB(A) option; press release quotes under 65 dBA
- Chinese site lists a paired AC-side configuration at 690 Vac (e.g. 400 kW × 8 PCS for the 0.5C options) — not part of the DC container itself

Price signal
$65–85/kWh
Our estimate, not a vendor offer: Narada is a tier-2 brand that typically bids near the bottom of Chinese tender ranges (H1 2026 spread RMB 420–782/kWh, 4-hour average ~$75 per CNESA). Ex-works China DC block; 20-ft liquid-cooled container for 2–8-hour applications, in mass production since July 2025.
