Mean Well ISI-501-148D True Sine Wave DC-AC Inverter 500W 110V out 12V in with MPPT Solar Charger

The ISI-501-148D is a 500W true sine wave DC-AC inverter designed for applications that need 110V AC output from a DC source. It is aimed at power conversion scenarios where clean AC output and integrated solar charging capability are important.

Yes. This model provides true sine wave output with total harmonic distortion below 3%, which makes it suitable for equipment that benefits from cleaner AC power. That is a key differentiator versus modified sine wave alternatives.

The listed DC input range for this model is 42 to 60VDC, and the AC output is 110V. Buyers should match it to systems designed around that DC input range rather than assuming a lower-voltage battery setup.

Yes. The ISI-501-148D includes a built-in 500W MPPT solar charger with typical MPPT efficiency of 98%. That makes it more than a standalone inverter and can simplify product selection for solar-related DC-AC applications.

This model includes battery low alarm, battery low shutdown, over voltage, over temperature, output short, input polarity reverse, and overload protection. The product data also states overload protection at 110% load for 60 seconds, with shutdown and recovery after re-powering on.

It is rated for operation from -20°C to +40°C at 100% load, with operation up to 60°C at 50% load. That makes it suitable for a range of industrial and commercial environments, provided the load and ambient conditions stay within the stated limits.

The listed compatible battery types are open and sealed lead acid. If your system uses a different battery chemistry, this model should be reviewed carefully against the manufacturer specifications before purchase.

The ISI-501-148D measures 205 x 158 x 67 mm and weighs 2.35 kg. It also carries a 3-year warranty, which is consistent with the product's industrial positioning.
