Key Features
🔋 1344Wh Energy Capacity 25% more storage energy. Perfect for households with higher power consumption or longer backup duration during grid outages.
❄️ Cold Climate Ready Discharge operating temperature down to ‑20°C. Stable performance for all climate zones across Pakistan.
🔌 73V High‑voltage Platform 64V nominal /73V full‑charge voltage. Good compatibility with large‑size solar inverters and multi‑battery parallel stacking configurations.
Safety Notes
- Use dedicated LiFePO4 charger with 73V charging voltage. Do NOT use lead‑acid charger.
- IP rating not specified; keep away from rain, water immersion.
- Do not charge below 0℃ to avoid cell degradation.
- For long‑term storage, maintain SOC at 40‑60%. Recharge periodically.
