Is there any way to determine the DC Voltage Input Limit of my inverter ? this inverter was once used for solar charging systems. but it has no labels, nor manuals . Thanks!
What is the output voltage supposed to be? 110? 220?
Once you know that, give an input starting with 6 volts, go to 12, 24, .... till you get the output voltage. That will tell you what the nominal input voltage.
