FAQ
What is the Mean Well ISI-501-112A designed for?
The ISI-501-112A is a true sine wave DC-to-AC inverter for converting 12V DC input into 110V AC output. It is suited for mobile, off-grid, and backup power applications where clean AC power and an integrated MPPT solar charger are useful.
What are the input and output ratings of the ISI-501-112A?
This model accepts a 10.5 to 15VDC input range and provides 110V AC output. Its continuous power rating is 450W, and it supports surge power up to 900W.
Does this inverter produce true sine wave output?
Yes, the ISI-501-112A provides true sine wave output with total harmonic distortion below 3%. That makes it a better choice for AC loads that benefit from cleaner waveform quality.
Does the ISI-501-112A include a solar charger?
Yes, this inverter has a built-in 500W MPPT solar charger. Mean Well lists typical MPPT efficiency at 98%, which helps improve solar charging performance in compatible systems.
What battery type is supported by the ISI-501-112A?
This model is specified for open and sealed lead-acid batteries. The product data provided for this model does not list support for other battery chemistries.
What protection features are included on this inverter?
The ISI-501-112A 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 voltage and requires re-powering to recover.
What environments can the ISI-501-112A operate in?
This inverter is rated for operation from -20°C to +40°C at 100% load. Mean Well also lists operation up to 60°C at 50% load, making it suitable for a range of industrial and mobile environments.
What are the size, weight, and warranty for the ISI-501-112A?
The unit measures 205 x 158 x 67 mm and weighs 2.35 kg. The datasheet does not state a warranty period, so confirm warranty terms at purchase.
