Jackery introduced the EnergyGuard Max home energy storage system at IFA Berlin. The unit consists of a 100 kWh Energycore battery module and a PowerVault 50 inverter. The system features a liquid-cooled LFP battery with a nominal capacity of 104 kWh, an operating voltage of 332.8 V, and a weight of 1.5 tons. Its dimensions are 971 mm by 1531 mm by 1308 mm.
The PowerVault 50 inverter supports a DC input voltage range of 150 V to 950 V and a maximum charging/discharging current of 2 x 80 A. The system is rated for 50 kW AC output at 230 V or 400 V, with a switching time of 10 ms. It includes the FortiShield Safety System, a 7-layer security framework, and various electrical protection mechanisms.
Designed for the European market, the system operates in temperatures down to -20 C. It supports up to 100 kWp of PV input power and can facilitate bi-directional charging for electric vehicles. The technology allows for peak shaving to reduce utility load and can be integrated into virtual power plants to sell energy back to the grid.
While pricing remains undisclosed, the company suggests the cost per kWh will be lower than typical home batteries. The system is intended for large homes or off-grid applications, providing enough capacity to power a household for days or weeks during outages. Production will take place at Jackery’s net zero factory.
