FAQ
What are the main output and input ratings of the Mean Well ISI-501-112C?
This model is a 450W true sine wave DC-AC inverter with 110V AC output and 12V DC input. Its input voltage range is 10.5 to 15VDC, making it suitable for 12V battery-based systems. It also supports surge power up to 900W.
Does the ISI-501-112C include a solar charger?
Yes. The ISI-501-112C includes a built-in 500W MPPT solar charger. Mean Well rates the MPPT efficiency at 98% typical, which helps improve solar charging performance in systems using this inverter.
What kind of AC output does this inverter provide, and why does that matter?
The ISI-501-112C provides true sine wave output with total harmonic distortion below 3%. That makes it a better fit for applications that benefit from cleaner AC power than a rougher waveform. For buyers comparing inverter types, this is one of the key differentiators of this model.
What battery types is the ISI-501-112C designed to work with?
This model is specified for open and sealed lead acid batteries. It also includes battery-focused protections such as low battery alarm, low battery shutdown, and over-voltage protection. Those features help protect the connected battery system during operation.
What protection features are built into the ISI-501-112C?
The ISI-501-112C includes protection for low battery alarm, low battery shutdown, over voltage, over temperature, output short, input polarity reverse, and overload. For overload, it can handle 110% load for 60 seconds before shutting down output. Recovery is done by re-powering the unit after a protection event.
Is the ISI-501-112C suitable for demanding environments?
It is rated for operation from -20°C to +40°C at 100% load, and up to 60°C at 50% load. The unit uses a built-in cooling fan to help manage heat. For buyers evaluating environmental fit, those published operating limits are the key reference points for this model.
What physical size and warranty does the ISI-501-112C come with?
The ISI-501-112C measures 205 x 158 x 67 mm and weighs 2.35 kg. The datasheet does not state a warranty period, so confirm warranty terms at purchase. Those details are useful when comparing enclosure space across inverter options.
