A continuous buzzing sound usually indicates a critical fault leading to shutdown, such as low battery voltage, overload, or overheating. The red Fault LED will typically light up, and the inverter will stop AC output to protect the device.
'LO' stands for Low Voltage protection, meaning the input battery voltage is too low. 'HI' indicates High Voltage protection where input voltage exceeds safe limits (e.g., above 16V for a 12V system). 'OL' signifies an Overload or short-circuit condition.
Yes, OLTEANP pure sine wave inverters produce clean, stable power with low harmonic distortion, similar to utility grid power. This makes them safe for sensitive electronics like laptops, CPAP machines, and medical equipment.
If the inverter shuts down due to an overload (OL code), you should disconnect the heavy load, turn the inverter's ON/OFF switch to the OFF position, wait a few seconds, and then turn it back ON to reset.
