Description
The 48V NEXUS battery from BigBattery provides renewable energy storage for off-grid, grid-tied, or commercial energy systems. A single battery stores up to 15kWh, and it’s possible to combine up to 15 batteries in parallel for up to 225kWh. Advanced features like fire suppression reduce electrical risks, and the internal heater makes it competent in many geographies.
Most modern batteries include a BMS (Battery Management System) to monitor the battery and turn it off in unsafe conditions. The BigBattery BMS monitors voltage, current, and temperature to make sure the battery operates within safe parameters. If any of these variables deviate from the safe limits, the BMS automatically turns off the battery to prevent electrical hazards.
The BMS also continuously monitors the cell levels to ensure uniformity across the battery. This feature adjusts the cells as needed to make sure each cell charges and discharges uniformly. This maintains battery health and increases battery life.
While LiFePO4 batteries are some of the safest on the market, fire suppression technology provides additional redundancy in the unlikely event of a fire. This battery continuously monitors the internal temperature, and should it heat to an unsafe point, the aerosol extinguisher activates.
It’s safe to discharge the NEXUS all the way to 0%, and when used repeatedly at 80% DOD (Depth of Discharge), it continuously operates for over 4,000 cycles.
BigBattery designed the NEXUS for cold weather climates. It can safely discharge when the temperature is -4-131°F, and it can safely charge when the temperature is 32-113°F. In colder climates, the internal heater activates to bring the battery temperature up to a safe charging temperature. This makes it suited for snowy climates.
It’s convenient to install this battery with the included connection cables. The shipment includes one communication and two power cables, all of which connect between the battery and the inverter.
The BigBattery monitoring software provides real-time insights into the BMS. Once installed and configured, the software displays battery information including the cell voltage and temperature, charge and discharge current, SOC (State of Charge %), and fault history.
Choose BigBattery’s NEXUS for a reliable cold-weather battery designed to deliver 15kWh to an off-grid home, grid-tied residence, or commercial energy system.
