FAQ
What is the Mean Well ISI-501-212D designed for?
The ISI-501-212D is a true sine wave DC-AC inverter for converting 12V DC input power into AC output for equipment that needs clean, stable power. It is aimed at applications that also benefit from its built-in MPPT solar charger and battery monitoring features.
What are the key power specifications of the ISI-501-212D?
This model is rated for 450W continuous output power and supports surge power up to 900W. It accepts a 10.5 to 15VDC input range and has a typical efficiency of 86%.
Does this inverter produce true sine wave output?
Yes. The ISI-501-212D provides true sine wave output with total harmonic distortion below 3%, which is important for sensitive electronics and loads that perform best on clean AC power.
Does the ISI-501-212D include a solar charger?
Yes. This model has a built-in 500W MPPT solar charger with typical MPPT efficiency of 98%, so it stands out from basic inverters that only provide DC-to-AC conversion.
What protection features are built into this model?
The ISI-501-212D 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 output voltage and requires re-powering to recover.
What battery types is the ISI-501-212D compatible with?
According to the provided specifications, this model is intended for open and sealed lead acid batteries. That makes it suitable for systems already built around those battery chemistries.
Can the ISI-501-212D operate in 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. A built-in cooling fan is included to help manage temperature during operation.
What else differentiates this inverter for commercial or field use?
This model includes remote ON-OFF control, a battery low relay contact, and LED indicators for operating status and battery capacity. It also carries IEC62368-1 CB and EAC TP TC 004 approvals.
