BigBattery NEXUS 2 Battery + EG4 6000XP Inverter| 16 kWh | Off-Grid ESS System

The BigBattery NEXUS 2 + EG4 6000XP ESS System delivers dependable off-grid power, high-capacity energy storage, and flexible system expansion for homes, cabins, workshops, and backup-power applications. Combining the 16kWh NEXUS 2 LiFePO? battery with the efficient EG4 6000XP off-grid inverter, this system provides a powerful foundation for energy independence in a compact, durable configuration.

The EG4 6000XP delivers 6,000W of continuous split-phase 120/240V output with up to 12,000W of surge power for approximately 3.5 seconds. Its dual MPPTs can utilize up to 8,000W of solar power, with support for up to 10,000W of recommended connected PV capacity, providing strong solar production and efficient battery charging throughout the day.

Paired with the NEXUS 2—featuring 16kWh of LiFePO? storage, 314Ah capacity, 150A continuous discharge, and up to 7.6kW of continuous battery power—the system can reliably support household essentials, appliances, tools, pumps, and other demanding off-grid loads. A peak discharge current of 270A for one second provides additional support when equipment initially starts.

The NEXUS 2 features an integrated BMS with multiple safety redundancies, RS485 and CAN communication interfaces, and a rugged IP54-rated floor-standing enclosure suitable for indoor or outdoor installation. Its advanced LiFePO? cells are rated for more than 8,000 cycles, providing over 12 years of service when cycled daily under appropriate operating conditions.

The EG4 6000XP can operate entirely off-grid or use grid or generator input for supplemental charging and load support. Built-in Wi-Fi connectivity enables remote monitoring and adjustments through EG4 software, while its LCD and LED interface provides convenient on-site system visibility.
