The Pytes E-Box 48100R TE+ is a powerful yet affordable home storage solution for modern PV and energy systems. With a capacity of 5.12 kWh and a nominal voltage of 48 V, this 48 V battery storage system offers an efficient way to store solar energy and maximize self-consumption. Thanks to its compatibility with Victron Energy systems, the E-Box 48100R TE+ is the ideal solution for Victron Energy ESS and other demanding applications.
As a modern LiFePO₄ solar storage system, the Pytes E-Box 48100R TE+ combines high safety with a long service life. The LFP chemistry (lithium iron phosphate) used ensures thermal stability and a very low fire risk – a plus point when the home storage system is installed near the house or in the utility room. The integrated battery management system (BMS) monitors all cells and ensures that the battery storage system operates within safe operating limits at all times. This means users benefit from a reliable and low-maintenance storage solution for their solar energy.
With a nominal energy of 5.12 kWh and a nominal capacity of 100 Ah, the Pytes E-Box 48100R TE+ is optimally designed for typical household loads, smaller commercial applications, and off-grid systems. The recommended charging and discharging current of 50 A (2.56 kW DC) provides solid continuous power, while the peak discharging current of 102 A (5.22 kW for 15 s) offers sufficient reserves for short-term load peaks. This makes the 48V battery storage system suitable for both daily operation in the Victron Energy ESS and for applications with higher starting currents, such as starting motor loads.
The E-Box 48100R TE+ offers particularly attractive value for money. Thanks to a round-trip efficiency of ≥ 95% and a cycle life of ≥ 6000 cycles (at 90% DoD), the storage costs per kWh remain very low over the entire service life. Combined with the 10-year manufacturer's warranty, users get an economical and durable solar storage system that perfectly matches high-quality Victron Energy components that are also designed for efficiency. The result is a coherent overall system consisting of an inverter, energy management, and home storage.
The Pytes E-Box 48100R TE+ is compact and flexible in use. With its dimensions in 2.6U rack format and a weight of 51 kg, the storage unit can be integrated into cabinets, racks, or technical rooms to save space. The permissible ambient temperature range of -10 °C to +50 °C allows it to be used in a wide variety of installation environments. Communication with compatible inverters and energy management systems takes place via the CAN and RS485 interfaces – ideal for a clean, closed system design with Victron Energy ESS.
Another advantage of this LiFePO₄ home storage system is its high scalability. A single module provides 5.12 kWh, but can be expanded to an energy storage system of up to 491.52 kWh in larger projects by connecting modules in parallel. This allows the solar storage system to grow flexibly with requirements – from small private PV systems to larger commercial or off-grid systems. Users thus receive a future-proof solution that also allows for easy expansion at a later date.

The Pytes E-Box 48100R TE+ is particularly suitable for PV system owners who want to increase their self-consumption and use an affordable but high-quality home storage system. It is also ideal for people who want to set up a Victron system with Victron Energy ESS at home and value a tested, Victron Energy-compatible storage solution. However, operators of small commercial enterprises or hybrid off-grid systems also benefit from the reliable power supply, high efficiency, and flexible expandability of this 48V solar storage system.
