All-in-One Solar Inverter with LiFePO4 Battery - Built-in AC + PV Dual-Charging Design & Pure Sine Wave Output

CKMINE All-in-One ESS Energy Storage System is a "dual-effect tool" that helps families mitigate the risk of power outages and reduce electricity costs. The system supports a maximum power of 12KW and a capacity of 20KWH. It can continuously supply power to critical devices such as refrigerators and air conditioners during power grid failures, and can also prioritize the use of stored photovoltaic power during peak electricity prices. 
It uses LiFePO4 lithium iron phosphate batteries, which have long cycle life and excellent thermal stability. Combined with BMS battery balancing technology, each battery cell remains in a consistent state, ensuring the long-term and efficient operation of the system. The pure sine wave output technology keeps sensitive electrical appliances (such as projectors and audio systems) away from voltage fluctuation damage. 
The built-in AC + PV dual-charging design enables the battery to be charged simultaneously from both the power grid and the solar panel. On sunny days, the solar panel takes priority in charging the battery, while on rainy days, it automatically switches to the power grid for charging to ensure sufficient power. 
From handling sudden power outages to achieving daily energy conservation and reduction, the CKMINE All-in-One ESS energy storage system combines reliable performance with "safety" and "cost-effectiveness". Now, by purchasing it, you can enjoy both cost savings and peace of mind when it comes to your household electricity usage.
