Key features that define Voltsmile solutions

Voltsmile boasts a range of exceptional features that set its products apart on the market:

High efficiency and long lifespan:
At the heart of Voltsmile systems are the highest quality LiFePO4/LFP+NMC battery cells, which guarantee optimal performance, longevity, and safety. They achieve an efficiency of >98% and offer more than 6,000 cycles (at 80% depth of discharge), making them a long-term investment. Some models, like the Voltsmile S1, specify >7000 cycles. All products come with a 10-year warranty.
Safety and durability:
The battery and management systems (BMS) use safe lithium iron phosphate (LiFePO4) battery cells. The products have robust thermal protection and meet high IP ratings, for example, IP65 (for outdoor use/Monoliths) and even IP65 (for some W series), ensuring resistance to dust and water. The outdoor AIO systems (V-fixR, R-all) have an IP54 rating with integrated climate control.
Intelligent energy management:
The systems include AI-driven optimization, Over-the-Air (OTA) updates, and full compatibility with solar systems. Monitoring is available via an application and remote updates.
Easy installation and flexibility:
- The Rapid Connection System (RSC) is a revolutionary feature that saves up to 60% on labor costs during installation. Thanks to built-in circuit breakers and an integrated cabling system, the setup is fast and minimizes the need for intervention.
- Modular and stackable designs (e.g., Monolith) enable scalable solutions based on specific energy needs and offer more versatile energy storage options.
- Many products are designed for integration into 19-inch server racks, which facilitates standardized installations.
Cold climate resilience:
Some batteries come in versions with built-in heating elements or are compatible with heating add-ons, allowing them to operate in temperatures as low as -20 °C.

High Voltage Compatibility:

With output voltages ranging from 51.2V to 672V, Voltsmile batteries are ideal for integration with high voltage inverters in both residential and mini industrial installations. To ensure compatibility of low voltage batteries with high voltage inverters, Voltsmile offers Levitate DC/DC transformers.

What is Voltsmile bringing to the field of energy storage?

Voltsmile continuously innovates and brings new products and solutions to the market:

Expansion into the commercial sector:
In 2025, Voltsmile is expanding its portfolio with commercial energy storage systems. New products include the powerful Vault and Raid systems, designed for factories, data centers, micro-commercial units, and hotels. For example, Raid 11 is the largest and most powerful system with a capacity of 112 kWh.
New product lines:
The 2025 catalog introduces a range of new models, such as the stackable Monolith, the high-voltage system's base components C Module, and the complete C-slz and C-AIO systems with integrated inverters. A new generation of the V10HPC Mark II battery was also introduced.
Emphasis on 2025 technical trends:
Voltsmile is actively contributing to key technical trends in the industry:
- LFP battery revolution: LiFePO4 (LFP) batteries dominate the market, powering 82% of new installations thanks to their 10,000-cycle lifespan and excellent safety.
- AI-driven energy management: Advanced algorithms can increase solar energy self-consumption by up to 35%. Voltsmile implements AI-driven optimization for more efficient battery management.
- Vehicle-to-Home (V2H) integration: Voltsmile is focusing on this growing area, where 23% of new installations already offer bidirectional charging.
Global reach and partnerships:
Voltsmile has installations in more than 60 countries and collaborates with over 300 partners. Their products are compatible with a growing number of major inverter brands, including Deye, Victron, GoodWe, and Sungrow.
Installation examples in the Czech Republic:
In the Czech Republic, Voltsmile systems are already in operation, for example, a Voltsmile W1 battery in Pavel K.'s installation or a V10 Classic system with a Victron inverter, with a capacity of 80 kWh.

Applications of Voltsmile solutions:

For everyone seeking energy independence

Voltsmile solutions are designed for a wide spectrum of applications:
