Mean Well ISI-501-124B True Sine Wave DC-AC Inverter 500W 110V out 12V in with MPPT Solar Charger

The ISI-501-124B is a 500W true sine wave DC-AC inverter for applications that need 110V AC output from a DC battery-based power system. This model also includes a built-in 500W MPPT solar charger, which makes it suitable for mobile, off-grid, backup, and solar-supported power systems where clean AC output is important.

This model provides a true sine wave 110V AC output with total harmonic distortion below 3%. That makes it a better fit for loads that benefit from cleaner AC power than modified sine wave designs can provide.

Yes. The ISI-501-124B has a built-in 500W MPPT solar charger, and the listed typical MPPT efficiency is 98%. That combination can reduce the need for a separate charger in solar-supported DC power systems.

The specified input voltage range for the ISI-501-124B is 21 to 30VDC. Buyers should match the inverter to a DC system that operates within that range rather than relying only on shorthand naming conventions.

Yes. The continuous power rating is 500W, and the product listing states surge power up to 1000W. It also has overload protection, with 110% load support for 60 seconds before shutdown protection is triggered.

This model 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 the output and requires re-powering to recover.

The listed operating range is -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 mobile environments, provided the load level stays within the published limits.

The specification lists open and sealed lead acid batteries as supported battery types. If your system uses a different battery chemistry, this product page does not confirm compatibility, so selection should stay within the stated battery support.
