Description

The BLUETTI AC300 + 2×B300K is a fully modular solar-powered home battery backup system designed to deliver reliable, high-capacity energy storage for both on-grid and off-grid applications. Featuring a robust 3,000W pure sine wave inverter (6,000W surge), the AC300 supports power-hungry appliances such as air conditioners, refrigerators, medical devices, and workshop tools with ease.

Paired with two B300K expansion batteries, this setup provides a total 6,144Wh of clean, long-lasting LiFePO₄ energy storage. The system supports solar input up to 2,400W, enabling ultra-fast recharge times—ideal for off-grid homes, RVs, van life, and emergency backup scenarios. You can expand the system up to 12,288Wh (4×B300K) for extended autonomy.

Integrated dual charging allows simultaneous input from solar and AC (or generator), and the smart BLUETTI App gives full remote control and monitoring over Wi-Fi or Bluetooth. With advanced UPS functionality, the AC300 switches to battery power in under 20ms to protect essential devices during blackouts.

“As a Senior Surveyor at Aurecon, I found Jamie and Alison from the Green Sky Team were extremely helpful and rapidly responded to our short notice request.
They showed a can-do attitude in mobilising a M350 drone with L2 LiDAR payload equipment to our site enabling Aurecon to meet our client's program objectives. Our RePL pilot found the equipment was well configured and faultless in performance. Highly recommend.”
