Why Choose This Product?
The ENVA 16 combines high-capacity LiFePO4 storage with built-in protection, local and remote monitoring, and practical floor-standing installation features. It is suited to projects where the inverter, battery communications and electrical installation are checked against Freedom Won requirements.
Important Notes
- The manufacturer's 5 June 2026 specification identifies this unit as ENVA 16 with 16kWh total energy. The supplier listing uses 16.07kWh; confirm the commercial naming convention if required.
- Maximum charge and discharge currents are permitted for five minutes per 30-minute cycle. Current ratings apply at 10°C to 25°C; derating applies outside this range.
- IEC 62619 is marked 'in progress' by the manufacturer and must not be treated as completed certification.
- For parallel installations, a custom combiner box is required. Confirm inverter compatibility and applicable firmware before installation.
- Do not short-circuit the battery or connect it with reverse polarity. Installation must be undertaken by a suitably qualified installer.
- Dimensions exclude protuberances; consult the installation manual for required clearances.
- Warranty and service-life figures are subject to manufacturer terms and operating conditions. Register and commission in accordance with Freedom Won requirements.
