FAQ

• Q: Can I connect multiple batteries in parallel?​
  A: Yes. Up to 3 units can be paralleled to reach 30kWh. The built‑in BMS automatically balances them.
• Q: Does it work with my existing solar inverter?​
  A: It works with most 48V inverters supporting CAN/RS485 communication. Check compatibility before purchase.
• Q: How long does it take to fully charge?​
  A: At 100A standard charge, about 2 hours. With max 200A, about 1 hour (if supported by charger).
• Q: Is it safe to install indoors?​
  A: Absolutely. LiFePO₄ is non‑flammable and emits no gas. Install in a dry, ventilated area.
