Mean Well ISI-501-112U True Sine Wave DC-AC Inverter 450W 110V out 12V in with MPPT Solar Charger

The ISI-501-112U is a true sine wave DC-AC inverter for applications that need 110V AC output from a 12V DC source. It is also differentiated by its built-in 500W MPPT solar charger, which makes it suitable for mobile, off-grid, and backup power systems using lead acid batteries.

This model provides 450W rated AC output at 110V. Its DC input range is 10.5 to 15VDC, so it is intended for 12V battery-based systems rather than higher-voltage battery banks.

Yes. The product is specified as a true sine wave inverter with total harmonic distortion below 3%, which is important for powering sensitive AC equipment that benefits from cleaner wave output.

Yes. Although its continuous power rating is 450W, the ISI-501-112U supports surge power up to 1000W. That helps with loads that draw a higher inrush current at startup, as long as normal running demand stays within the unit's rated output.

The specification lists open and sealed lead acid batteries as the supported battery types. This answer is specific to the provided product data, so other battery chemistries should not be assumed compatible from this listing alone.

This inverter includes battery low alarm, battery low shutdown, over voltage, over temperature, output short, input polarity reverse, and overload protection. For overload, over temperature, and output short conditions, the unit shuts down output and requires re-powering to recover.

It is rated for operation from -20°C to +40°C at 100% load, and up to 60°C at 50% load. The unit also uses a thermostatically controlled cooling fan, which supports thermal management in working environments with variable load and temperature conditions.

The ISI-501-112U is listed as approved to IEC62368-1 CB and EAC TP TC 004, and it meets BS EN/EN62368-1. Mean Well also specifies a 3-year warranty for this model.
