Key features

• Pack of 4 batteries for a total capacity of 20.48 kWh
• Charge and discharge possible up to -20 °C
• LiFePO4 technology for sustainable storage
• Wall mounting or floor installation
• 4.3-inch screen on each battery
• Bluetooth and Wi-Fi for supervision
• Integrated smart BMS on each unit
• 125 A circuit breaker and precharge circuit
• RS485 / CAN / RS232 communication
• 2-year warranty

This pack of 4 wall-mounted 48V 100Ah batteries is intended for users who wish to go beyond simple energy supplementation and have a substantial storage capacity. With 20.48 kWh available, it allows better absorption of excess solar production, smooths consumption throughout the day, and significantly increases the autonomy level of a residential or technical installation.

It is a particularly relevant solution for homes equipped with a photovoltaic system, secondary residences, cabins, autonomous buildings, or hybrid installations combining multiple energy sources. In case of a network outage, the available reserve also allows for maintaining priority uses longer.

Each battery in the pack includes the same control and safety equipment: smart BMS, 125 A circuit breaker, precharge circuit, 4.3-inch screen, as well as interfaces Bluetooth, Wi-Fi, RS485, CAN, and RS232 for monitoring and system integration.

Another major advantage: operation at very low temperatures. This pack is suitable for installations exposed to cold thanks to a charge and discharge range from -20 °C to +55 °C, meeting the needs of demanding environments and minimally heated technical rooms.

Recommended uses

• Solar self-consumption with enhanced storage
• Autonomous or semi-autonomous house
• Domestic backup reserve
