Thanks to its modular design, the AC500 supports up to 6×B300S or 4×B300(B300K) (or a combination of B300(B300K) and B300S) expansion batteries with a total capacity of 18,432 Wh and 12,288(11,059) Wh respectively, covering your off-grid power needs!
The built-in inverter delivers a continuous output of 5000 W with a pure sine wave and can handle short-term spikes of up to 10 kW at peak power, ensuring that whatever you connect will operate at full functionality and potential with ease. It is suitable for any scenario, whether you’re camping or having a barbecue in the garden.
Powered by an efficient MPPT controller, the AC500 delivers up to 3000 W of solar power – 40% faster than standard charging speeds, so a full charge of the AC500+B300K combo takes approximately 1.5 hours*.
*Charging time is calculated under ideal conditions and is for reference ONLY. Actual charging time may vary depending on ambient temperature and other factors.
The AC500 system is designed to be charged in whatever way you prefer, for example, by connecting directly to solar panels, a car cigarette lighter socket, or more efficiently using a 5000W charging cable. What’s even more impressive is that the AC500 can handle up to 8000W of peak power consumption, allowing it to fully charge in just 1.5 hours.
Whenever the mains power fails, the AC500 system automatically becomes your home power source, ensuring all your essential loads continue to operate without interruption. It also utilises an advanced Battery Management System (BMS) and a LiFePO4 battery(not included) to ensure a higher level of safety during operation, a longer service life and optimal performance.
The intuitive BLUETTI app and touchscreen allow you to monitor everything, including power input/output, real-time energy consumption, charging profiles, OTA firmware updates, etc.
