In today's competitive PV market, every minute counts. As an installation company, you know that the time spent on a single job directly impacts your profitability and your ability to take on the next one. What if there was a battery system that allowed you to complete installations faster, with less risk of error, and with greater safety for your technicians? That's exactly what the Voltsmile V10 RPC battery, with its innovative Rapid Connection System (RPC), delivers.

This system isn't just another minor innovation—it's a fundamental change that optimizes the entire installation process. Let's take a look at why the V10 RPC battery should become the cornerstone of your residential and small commercial projects.



The End of Tedious Cabling: The Magic of the RPC System


Imagine installing a battery storage system without needing to interconnect individual modules with dozens of power cables. No complicated terminal tightening, no checking the correct polarity at every connection. The Voltsmile RPC system makes this a reality.

Its genius lies in the integrated busbars and pre-wired cabling located directly in the back of the specially designed rack cabinets. This makes the installation incredibly simple and fast:

  1. Position and anchor the RPC cabinet.

  2. Connect the main power and communication cables from the cabinet to the inverter.

  3. Simply slide the individual V10 RPC battery modules into the rack and secure them.

  4. Set the DIP switches, and you're done.

This "plug-and-play" approach dramatically shortens on-site time and minimizes the risk of human error. Voltsmile states that thanks to the RPC system, you can save up to 60% on labor costs during installation. For your company, this means the ability to complete more installations in the same amount of time, thereby directly increasing your revenue.


Performance and Reliability You Can Count On


Behind this revolutionary installation system lies a robust and powerful battery designed for the needs of modern households.

Key Parameters of the Voltsmile V10 RPC:

  • Cell Chemistry: Lithium-iron-phosphate (LiFePO4) – the safest and most durable technology on the market, free of problematic cobalt.

  • Module Capacity: 5.12 kWh.

  • Nominal Voltage: 51.2 V (low-voltage system).

  • Charge/Discharge Current: 100 A continuous.

  • Lifespan and Warranty: Designed lifespan of over 10 years, guaranteed for more than 6000 cycles, and backed by a standard ten-year warranty.


The following overview summarizes the available cabinet models designed specifically for V10 RPC batteries:

What Does This Mean in Practice for Your Customer?


A high charge and discharge current of 100 A at 100 Ah capacity means a 1C rate. This allows the battery to effortlessly cover energy peaks when multiple appliances are running simultaneously in the household—such as a heat pump, an oven, and an EV charger. At the same time, it can quickly store all excess energy from the solar panels during peak sun at noon. It's a reliable and powerful partner for any home, one that won't limit its energy potential.


Safety and Scalability First


The low-voltage architecture (under 100 V) is inherently safer for installation and handling compared to high-voltage systems. For your technicians, this means a lower risk of electric shock and simpler work procedures.

Furthermore, the system is highly modular. Individual 5.12 kWh modules can be easily added and connected in parallel, up to 63 units, achieving a total capacity of over 322 kWh. This gives you the flexibility to design custom solutions for standard family homes as well as larger residential or small commercial projects.


Compatibility and Compliance


The Voltsmile V10 RPC battery is designed for seamless integration with a wide range of inverters thanks to standard CAN and RS485 communication ports. Compatibility is confirmed with devices from leading brands such as Victron Energy, Deye, and others.

Voltsmile also provides a compatibility list to make integration as simple as possible.

The product meets all key European and international standards, evidenced by certifications such as CE, IEC62619, UN38.3, and ROHS. Your customers can be confident they are investing in a safe and proven product. Of course, the installation itself in the Czech Republic must comply with valid national standards, especially the ČSN 332000 series and other regulations for battery storage systems.
