AMVOLT 10 kWh LV Energy Box LiFePO4

The AMVOLT 10 kWh LV Energy Box is a scalable and compact open storage system composed of individual battery cells and interchangeable standardized components. This significantly extends the lifespan of the entire storage system. The Energy Box features an integrated Battery Management System (BMS) made in the EU, which monitors the temperature, current, and voltage of each cell. It also controls the charging of the battery system and balances the cells when necessary and when the battery is fully charged (passive method). The BMS also includes a temperature sensor that will automatically disconnect the entire battery from the rest of the system in case of over-temperature of the battery box (55 °C). The BMS calculates the state of charge (SoC), state of health (SoH), and internal resistance of each cell. It transmits information about the charge status, voltage, and current to the inverter via a CAN interface.

10 kWh variant is designed for 32 pieces of ELERIX EX-L100 batteries (3.2 V; 100 Ah) and operates at a voltage of 51.2 V. The battery cells are manufactured in accordance with CSN EN 62619 and have been tested in accordance with this standard (TÜV Rheinland).

The AMVOLT LV Energy Box can be used either independently or expanded with up to two additional units (up to a total capacity of 30.6 kWh). Expansion always requires the use of the AMVOLT Master Unit, which functions as superior control over individual "slave" energy boxes. This ensures double security for the entire system.

Usage:

• Low-voltage battery storage for inverters operating at 48–60 V
• Scalable storage system with a capacity of up to 30.6 kWh (requires AMVOLT Master Unit)
• High-power applications (peak shaving) or off-grid projects at low voltage (max. 2 C).

AMVOLT's technical philosophy is to build open storage systems in the Czech Republic from individual battery cells and interchangeable standardized components. This significantly extends the life of the entire storage system compared to the now widespread closed, non-repairable battery boxes and drawers.
The AMVOLT LV Energy Boxes are intentionally designed to allow the customer to have the option of any future expansion, modification or service without depending on the AMVOLT itself.

Competitive comparison:

AMVOLT 10 kWh LV boxes are freely scalable (in increments of 10 kWh) and offer customers a complete solution in a compact, modular, industrial form for indoor placement or as part of a container variant. All components except cells (i.e. contactors, relays, BMS, protection circuits...) are made in the EU and USA.

BMS and communication:

AMVOLT LV Boxes have an integrated BMS of their own design manufactured in the Czech Republic.
It is deliberately not connected to any foreign cloud (for security reasons), but at the same time it allows remote control and monitoring by direct access through a firewall which the customer has under his complete control.
The current is measured by the shunt. The BMS provides the calculation of the SoC, SoH and internal resistance values of each cell.

Basic parameters:

Supported inverters: Victron, SMA, Solax, Solis, Pylontech, Deye, Growatt and many more in the future.

Warranty Terms:

• Warranty of 10 years on the mechanical design and 10 years & 8,000 charge cycles (whichever comes first) on the battery cells.
• 5 years warranty on the battery's protective electrical circuitry (BMS).
• Lifetime warranty for technical support, service and extension.
