The BPlus series 300W inverter is a unique “Bipolar” DC to AC converter via true sine wave power inverter, strong load capacity, especially for sensitive loads, full load THD = 2%. The 300W inverter continuous power 300 watts and 900 watts surge power that provides reliable transformation to AC power from a battery, suitable for 12V vehicles, RVs, and small off-grid systems. AC output power is used to run computers, fans, televisions, stereos, satellite receivers, and sensitive loads. AC output 120V or 230V, battery type, and frequency setup by the display. BPlus series 300W inverter can be used full load for long periods and provide all protection.

Quality Control:  
1. GB/T19001-2016 IDT ISO9001:2015. 
2. Standard high-quality components. 
3. Quality inspection of the 5 processes of the assembly line. 
4. PCB ultrasonic cleaning and all PCB Three anti-paint protection.
5. 100% full power 30 minutes aging for different load types.
6. Before packing 5 function testing, including sine wave, low/over voltage, USB charger, and short circuit.

1. The 300W inverter should be installed in a dry, well-ventilated environment, keeping the inlet more than 20CM away from the wall.
2. Non-professional please don’t open the 300W inverter, because of the high voltage inside the inverter. When open by yourself without warranty.
