BP120B is an established 1200W portable power platform combining 1120Wh battery capacity with pure sine wave AC output, fast AC charging and multiple USB, DC and AC outputs.Designed for outdoor power, temporary backup and OEM projects, the platform also supports solar charging, UPS operation and expandable battery capacity.
1200W Power with 1120Wh Capacity
With 1200W rated output and 2400W surge power, BP120B provides portable AC power for a range of outdoor, mobile and temporary backup applications.
Its 1120Wh battery capacity provides additional runtime within the 1kWh-class portable power station category while maintaining a compact all-in-one format.
LiFePO4 Battery for Long-Term Use
BP120B uses a 1120Wh LiFePO4 battery and is rated for more than 2,500 cycles to 80% of original capacity.
The battery management system monitors key operating conditions including over-current, over-voltage, low-voltage, short-circuit and temperature protection.
Established Platform with Service-Oriented MPPT Architecture
BP120B uses a separate MPPT charging board rather than integrating the MPPT circuit into the inverter main board.
This architecture provides greater separation between major power modules and can simplify servicing of the charging section, making BP120B an alternative platform for projects where serviceability is an important consideration.
Multiple Ways to Recharge
BP120B supports charging from AC power, solar panels and vehicle power sources.
With up to 800W AC input, a full recharge takes approximately 1.5 hours. Solar charging supports up to 300W input, with an estimated charging time of approximately 4 hours under suitable conditions.
AC and solar input can also be combined for up to 1000W total input, reducing charging time to approximately 1.3 hours.
Expandable Capacity for Longer Runtime
Connect two additional 1120Wh battery to increase total capacity to 3360Wh for longer-duration outdoor and backup applications.
Extra batteries are sold separately.
Multiple Outputs for Portable Devices
Power laptops, portable electronics, lighting and other compatible devices through AC, USB-C, USB-A and DC outputs. The 100W USB-C PD port provides fast charging for compatible USB-C devices.
UPS Backup Function
BP120B supports UPS operation to provide backup power for compatible connected devices during temporary mains interruptions.
Optional Features
15W Wireless Charging
Optional App Control
