Improvements over the previous model, the Pytes V5a

Compared to the Pytes V5 alpha, the V5a Plus offers even greater scalability: Instead of a maximum of 430 kWh (14 modules), it now supports up to 491 kWh (96 modules). In terms of peak charge/discharge current, the new model delivers up to 200 A for 15 seconds—the previous model offered a maximum of 150 A. The integrated Wi-Fi functionality now enables remote monitoring and software updates as standard, while the heating mat ensures operation down to –18 °C (previously –10 °C). The V5a Plus also sets new standards with its housing, featuring improved connectivity and a well-thought-out design, yet remains compact at 45.34 kg.

Innovative Heating Mat: Worry-Free Even in Freezing Conditions

The optional, integrated heating mat in the Pytes V5a Plus ensures that the battery operates reliably even at outside temperatures as low as –18 °C. As soon as the cell temperature drops below 5 °C, the heating system activates automatically and ensures that charging and operation continue efficiently and safely. The heating mat shuts off again only when the cell temperature reaches 15 °C—a bonus in terms of safety and convenience, especially for installations in unheated rooms or outdoors.

Flexible Scalability: Future-Proof and Tailored to Your Needs

With the Pytes V5a Plus, energy storage systems can be customized to any size—from a single battery in a single-family home to a large-scale system with up to 96 modules and a total capacity of 491 kWh (in parallel configuration). A tower can contain up to 16 battery units and can be further expanded to up to 6 groups within a single system (with a separate drive). The modular design makes it easy to expand storage capacity at any time without having to undergo a complex retrofit of the existing system.

Triple-layered high-performance safety architecture

The integrated BMS continuously monitors all cell parameters (voltage, current, temperature, state of charge/SOC) and responds to irregularities (e.g., overvoltage, undervoltage, overcurrent, overtemperature) with targeted protective measures. The BMS controls the system via communication protocols and notifies the inverter of any hazardous conditions. An electronic main switch and a physical fuse provide additional layers of protection (e.g., in the event of a short circuit or emergency shutdown).

Smart Remote Monitoring and Easy Integration

The V5a Plus can be seamlessly integrated into numerous energy management and inverter systems via CAN, RS485, and Wi-Fi. Through the Wi-Fi connection, the battery status can be monitored in real time at any time and from anywhere, and firmware updates can be conveniently installed. Data visualization and alarm notifications ensure transparent control and simplify day-to-day monitoring.
