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

This model provides a 110V AC true sine wave output with total harmonic distortion below 3%. That makes it a better fit for sensitive electronics and equipment that benefit from clean AC power rather than a modified sine wave output.

The inverter is rated for 500W continuous output power and supports surge power up to 1000W. Buyers should size loads so normal operating demand stays within the 500W continuous rating.

Yes. The ISI-501-124U includes a built-in 500W MPPT solar charger, and the listed typical MPPT efficiency is 98%. This combination can be useful in off-grid and battery-backed power systems where inverter and solar charging functions are needed in one unit.

The provided specification lists compatibility with open and sealed lead-acid batteries. The same spec block lists an input voltage range of 21 to 30VDC, so buyers should verify their battery system voltage matches that range.

This model includes battery low alarm, battery low shutdown, over-voltage, over-temperature, output short, input polarity reverse, and overload protection. For overload, the provided spec states 110% load for 60 seconds, with shutdown and recovery by re-powering on.

It is rated for operation from -20°C to +40°C at 100% load, and up to 60°C at 50% load. The unit also uses a thermostatically controlled cooling fan, which supports operation under changing thermal conditions.
