Bluetti B300S Battery
Bluetti Battery Expansion 3072 Wh

Flexible Recharging

Thanks to the built-in MPPT, you can charge the BLUETTI B300S with a maximum solar power of 500W directly without a converter, both from the wall socket and via solar panel. The battery can also be charged in stand-alone mode without converter with maximum 1000W charging current via the Charging Enhancer accessory combined. It also supports charging AC, car and lead acid batteries. A D050S Charging Enhancer is required to charge car and lead-acid batteries.

Versatile Power Source

You can power your smartphones, laptops, fans, lights, refrigerators, microwave ovens, and so on with specific output port - the 100W USB-C, 12V/10A cigarette lighter, and 18W USB-A output ports.

Expandable Battery Pack

B300S has 3072Wh capacity and over 3,500 life cycles with the LifePO4 battery cells, offering up to 80% of original capacity. Moreover, it will double, triple, even sixfold the total capacity with BLUETTI AC500 Inverter. The difference to the B300 battery module is the higher output power, which was developed for the AC500. Each B300S battery module has a dedicated built-in MPPT controller and an integrated BMS (Battery Management System) which makes the battery a versatile and portable energy storage device even without a converter.

Home Backup and Trip Power Bank

Whether in a family gathering or camping trip, B300S will serve as your backup power supply or power bank. It powers your home and camping necessities well, and all you need to do is enjoy the good times.

In use at Home

At home as a hybrid grid solution with grid connection, combined with solar modules from Bluesun or off-grid with solar only, you can use an energy storage of 18.4 KWh in combination with 1 AC500 and 6 B300S expansion batteries. Combine two AC500 with 6 B300S expansion batteries and you get a whopping 36.8 KWh of energy storage capacity. Depending on your lifestyle and the size of your house, you can go a good 7 days without sun or grid power. If you take two AC500 systems, you serve different circuits with it.

In your Off-Grid Cabine or Camper

Note on model compatibility

The Bluetti B300S battery extensions are currently only compatible with the AC500 converter, but not with Bluetti AC200max or Bluetti AC300 power stations. On the other hand, the AC500 can use both Bluetti B300 and Bluetti B300S as storage.
