【Scalable Capacity】
The BetterESS 51.2V 30kWh All-in-One Battery, integrated with a powerful 12KW three-phase inverter, supports seamless parallel connection with identical models to scale up capacity. It is also compatible with the 30kWh expansion battery (BE-MB51600-300A-HWB), making it an ideal solution for large-scale energy storage needs. Please note: all parallel-connected batteries must be purchased from the same supplier and be of the same brand.
【Versatile Applications】
Designed with safety, efficiency, and sustainability in mind, the BetterESS 30kWh All-in-One LiFePO4 battery delivers exceptional energy density, extended lifespan, and superior temperature performance. Enjoy versatile charging options: harness solar energy, grid power, or both simultaneously for uninterrupted supply. It is perfect for solar-powered homes, off-grid living, emergency backup power, and eco-friendly energy solutions.
【Features】
Built to last over 10 years with 6000+ cycles at 80% DOD, this system offers extra safety through an active balancer and temperature-triggered LiFePO4 fire extinguisher. Its all-in-one design combines battery and inverter, making installation quick and hassle-free with plug-and-play convenience.
【Time-Slot Charging & Discharging】
The BetterESS 12 kW three-phase integrated system features intelligent time-slot charging and discharging. Users can set charging and discharging times to match local peak and off-peak electricity tariffs. During peak hours, the inverter supplies power from the battery; off-peak, it draws cheaper grid electricity to run the load and recharge—helping you cut energy costs efficiently.
