Introducing EG4’s game-changing 48V 14.34kWh PowerPro, the ultimate solution for residential and commercial ESS! This UL-certified, wall-mountable battery ensures reliable, efficient power delivery for any home or business, allowing you to see massive lifetime savings on your utility costs, and when paired with solar, you’re able to benefit from incentive programs and tax credits.


The PowerPro was designed with safety, longevity, and visibility in mind, with a lifespan of over 8000 cycles at 80% DoD. That’s 82.6MWh of lifetime production! This battery comes equipped with LiFePO4 cells, the safest chemistry on the market today, and an all-weather, IP65-rated design that ensures peace of mind through every season. Plus, the PowerPro’s intelligent BMS continuously monitors and records module and cell voltage, current, and temperature in real-time, in addition to a passive cell-balancing function, optimizing performance and ensuring long-lasting power, and an LCD touch screen display on the side of the unit allows you to stay up to the date on the status of your battery day in and day out.


Not only does the PowerPro feature an automatic self-heating function and dual fire extinguishers for fail-safe protection in case of thermal runaway, but EG4 continues to innovate with an all-new emergency stop function. This optional ESS disconnect is capable of shutting down your entire power system at the press of a button, so should an emergency happen, you’ll always be prepared. 


The PowerPro serves as the foundation for EG4’s PowerPro ESS Systems, but this battery can be paired with any hybrid or off-grid inverter you may already have installed. It’s time to revolutionize how you power your home or business.9
