Charging

AC Charging

Simply plug the B300S into a standard wall outlet and start charging.

Diagram showing the BLUETTI B300S connected to a Wall Outlet via an AC Adapter.

PV Charging

Connect the solar panels (in series or parallel) to B300S with the DC input cable.

Note: Please make sure your solar panels comply with:

• OCV³: 12-60V
• Vmp⁴: 12-60V
• Input Power: 500W Max

With the same power connector (MC4). DO NOT mix different types of solar panels.

Example: Connect two BLUETTI PV200 solar panels in series to charge the unit.

• BLUETTI PV200: Voc=26.1V, Vmp=20.5V, Current=9.7A Max.
• Total: Voc=26.1×2=52.2V, Vmp=20.5×2=41V, Current=9.7A Max.
