Pure sine wave inverters are only suitable for 12V battery systems, and failure to comply with minimum DC requirements can lead to irreversible damage to the device. Pay attention to the plus and negative poles, confusion of the poles can lead to damage to the inverter and trigger the internal fuse. Avoid turning on the inverter when the load (electronic device). there is already switched on, there is this can lead to overload, as some electronic devices first require a high current surge when switched on. Do not connect the AC output of the device directly to a switch panel / load centre operated with city power/generator. The inverter can be used in a variety of scenarios. It not only has a strong and continuous working ability indoors, but also a great adaptability outdoors, so it can be used in a variety of scenarios according to the needs of customers. Please pay attention to the ventilation conditions when using, long time without ventilation may cause the inverter to work continuously.
