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

The ISI-501-124A is a 500W true sine wave DC-AC inverter for applications that need 110V AC output from a 12V battery-based power system. It also includes a built-in 500W MPPT solar charger, which makes it suited for mobile, off-grid, and backup power use cases where solar charging is part of the system.

Yes. The ISI-501-124A provides true sine wave output with total harmonic distortion below 3%. That makes it a better fit for sensitive electronics and equipment that perform best on cleaner AC power.

This model is a 12V-class inverter with an input voltage range of 21 to 30VDC and a 110V AC output. Buyers should confirm that their power system matches this voltage range before selecting this unit.

The rated output power is 500W. It also supports surge power up to 1000W, which helps with short startup demands from compatible loads, but the continuous load should remain within the 500W rating.

The ISI-501-124A is specified for open and sealed lead-acid batteries. If your system uses a different battery chemistry, you should verify compatibility before purchase because the listed battery support is limited to those lead-acid types.

This model includes battery low alarm, battery low shutdown, over voltage, over temperature, output short, input polarity reverse, and overload protection. For overload, it can handle 110% load for 60 seconds, and protection recovery requires re-powering the unit.

It is rated for operation from -20°C to +40°C at 100% load, and up to 60°C at 50% load. That gives it flexibility for many industrial, mobile, and enclosed equipment environments, provided the load level stays within the stated limits.

The ISI-501-124A combines a 500W true sine wave inverter with a built-in 500W MPPT solar charger, rather than serving as only a standalone inverter. It also includes features such as remote ON-OFF control, battery low relay contact, LED status indication, and up to 88% efficiency.
