Voltsmile W1 Wall-Mounted Li-ion Battery – The Future of Space-Saving Energy Storage
Engineered for Demanding Power Needs
The Voltsmile W1 Wall-Mounted Li-ion Battery (51.2V 200Ah | 10.24kWh) redefines energy storage with its industrial-strength performance and space-optimized design. Perfect for homeowners and businesses alike, this system delivers uninterrupted power while occupying minimal space, because reliable energy shouldn’t mean sacrificing your wall.
Why the W1 Stands Out
1. Power That Fits Anywhere
- Wall-mounted design saves floor space (ideal for garages, utility rooms, or outdoor sheds)
- IP67 protection withstands dust storms, heavy rain, and even temporary submersion
- -30°C to 60°C operational range – tested in Arctic winters and desert summers
2. Unmatched Energy Resilience
- 10.24 kWh capacity powers essentials for 18+ hours (fridge, lights, WiFi)
- ≤8ms transition during grid outages – so fast your devices won’t flicker
- Parallel expansion up to 61.44 kWh (6 units) for whole-home backup
3. Smart & Safe Operation
- Self-heating/cooling system maintains optimal 25°C battery temperature
- Military-grade BMS prevents overcharge/over-discharge (±0.3V precision)
- Aerosol fire suppression deploys in 0.2 seconds (non-toxic KNANO2 formula)
4. Solar-Ready Efficiency
- 98% round-trip efficiency when paired with solar inverters
- Time-of-use optimization automatically stores energy when rates are low
- Remote monitoring via smartphone app (iOS/Android)

Installation & Maintenance: Simplicity Redefined
The Voltsmile W1 revolutionizes energy storage setup with its plug-and-play installation – no specialized tools or electricians required. Its pre-configured wiring harnesses and color-coded terminals enable homeowners to mount and activate the system in under 2 hours. For professionals, the W1 offers DIN rail-compatible communication ports for seamless integration with Victron, SMA, or SolarEdge ecosystems. Maintenance is equally effortless:
- Self-diagnostic alerts flag issues via LED indicators and mobile app notifications
- Front-access service panels allow module replacement without unmounting
- Automatic firmware updates ensure peak performance and security patches
This maintenance-free design has earned the W1 the 2025 EU Sustainable Product Award for reducing technician visits by 80% compared to conventional systems.
