High storage capacity for demanding energy systems

With a rated energy capacity of 16.07 kWh, the Pytes V16 is ideal for residential energy storage, larger PV systems, and smaller commercial applications. Its high capacity enables efficient temporary storage of excess solar energy, which can increase self-consumption and reduce grid draw. As a low-voltage battery, the storage system operates at a nominal voltage of 51.2 V and can be used in many commercially available energy storage systems. The permissible voltage range is between 46.5 and 56.8 V.

LiFePO4 Technology for Long Service Life

The V16 utilizes lithium iron phosphate (LiFePO4) cells. This cell chemistry is characterized by high thermal stability, a long service life, and high cycle stability. According to the manufacturer, the storage system achieves at least 8,000 charge and discharge cycles under defined test conditions and has a calendar lifespan of at least ten years. This makes the storage system suitable for long-term daily use in photovoltaic systems.

High Charge and Discharge Power

The battery storage system supports a recommended charging current of 125 A (6.4 kW) and a recommended discharging current of 150 A (7.68 kW). For short periods, it can deliver up to 200 A or 10.24 kW. This allows it to reliably power even larger household appliances or handle high load peaks.

Designed for year-round use

The Pytes V16 is equipped with an integrated battery heater. This supports operation at low temperatures and expands the usable operating range. The battery can be charged at temperatures ranging from 0 to 55 °C and discharged between -20 and 55 °C. Combined with its IP66 protection rating, the storage system is suitable for both utility rooms and protected outdoor areas.

Comprehensive Safety Features

• To ensure safe operation, the V16 features several built-in protection mechanisms:
• Integrated DC circuit breaker
• Pre-charge circuit
• Battery management system (BMS)
• Aerosol fire suppression module
• Protection against overcharging, deep discharge, short circuits, and overcurrent
• Temperature monitoring
• Cell balancing
• Reverse polarity protection for power cables

The integrated BMS continuously monitors the voltage, temperature, state of charge, and currents of each battery and automatically protects the entire system from critical operating conditions.

Scalable storage system

The Pytes V16 supports parallel operation of up to 16 batteries. This allows storage capacity to be flexibly adapted to growing demands without having to replace the existing system. Communication between multiple batteries occurs via RJ45 daisy-chaining, with one battery acting as the master.

Wide Inverter Compatibility

Thanks to support for CAN and RS485 communication, the storage system can be used with numerous energy storage inverters. Supported devices include those from:

• Deye / Sunsynk
• Victron
• Solis
• GoodWe
• Growatt
• SMA
• Sol-Ark
• LuxPower
• MUST

• Hoymiles / APsystems
• Livoltek
• Afore
• Phocos
• Voltronic
• Aiswei
• Senergy
• Ingeteam
• Epever
• SRNE
• Megarevo

Communication is handled via preconfigured DIP switch settings corresponding to the inverter being used.

Convenient Installation and Monitoring

The V16 can be mounted either on a wall or on a floor stand. The connections are clearly arranged, enabling easy commissioning. The LSW-5 Wi-Fi dongle is available as an option, allowing you to monitor operating data and perform firmware updates.
