The BLUETTI AC500 + B300S is a powerhouse engineered for the most demanding electrical environments. As a completely modular system, the AC500 acts as the high-performance brain, allowing you to build a custom energy reservoir that perfectly matches your requirements. Whether you are running a remote construction site, a full-sized luxury RV, or a comprehensive home emergency system, the AC500 + B300S provides silent, gas-free, and professional-grade electricity that outperforms traditional combustion generators.
What defines this home battery backup power kit is its staggering 5,000W pure sine wave inverter. Capable of handling a 10,000W surge, this system can start and run heavy-duty appliances that smaller stations simply cannot, such as central air conditioners, high-torque power tools, and large kitchen ranges. The “clean” nature of the electricity ensures that while you’re running high-draw hardware, your sensitive workstation computers and high-end electronics remain protected from surges and noise.
The inclusion of the B300S battery module introduces a new level of environmental resilience. Unlike standard batteries that struggle in freezing temperatures, the B300S features an intelligent self-heating function, ensuring optimal performance even in extreme cold. The system’s scalability is equally impressive; while the kit starts with a substantial 3,072Wh, you can connect up to six B300S modules to reach a monumental 18,432Wh total capacity . This is enough energy to sustain a modern home’s essential loads for nearly a week during a prolonged grid failure.
The AC500 + B300S kit is designed to minimize downtime with industry-leading charging technology. By utilizing a dual-charging approach, the system can accept up to 3,000W of solar energy and 5,000W from a wall outlet simultaneously, reaching a 8,000W total input rate . This allows the massive battery array to be replenished in record time, ensuring you are always ready for the next adventure or emergency. With the BLUETTI Smart App , you have a full command center in the palm of your hand, allowing you to monitor real-time stats and manage energy distribution with precision. For the ultimate in power, performance, and peace of mind, the BLUETTI AC500 + B300S is the definitive choice.
