FAQ
What is the Mean Well ISI-501-124A designed for?
The ISI-501-124A is a 500W true sine wave DC-AC inverter for applications that need 110V AC output from a 24V 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.
Does this inverter produce true sine wave output?
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.
What input and output voltage does this model support?
This model is a 24V-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.
How much power can the ISI-501-124A deliver?
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.
What battery types is this inverter compatible with?
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.
What protections are built into this inverter?
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.
Is this model suitable for demanding temperature conditions?
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.
What makes this model different from a basic 500W inverter?
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 87% typical efficiency.
