Question about Coleman Cable Power Inverter PMP1200
What does it invert?Higher voltage to lower or what?Either way,with 1200 watts being inverted,it is not a good idea to charge a battery with that kind of power.Batteries need to be charged low and slow.We are talking milliamps for hours.Fast charging a battery results in a very good chance of explosion,which is never good.Acid from the battery will go everywhere.

please check the voltage your generator is supplying to the to the inverter because a high voltage and frequency can make the relays in the inverter to make clicking sounds,and also do not allow your inverter batteries to run completely low before you charge it

Hi, well you see this happened because the "Load" on the Inverter was more than it could handle. You see the Inverter senses the resistance of the batteries to determine how flat they are and how much current to put into the batteries, if anything else is connected to said batteries, that will simply muck up the sensing,and as has happened in your case destroyed the inverter.
I have serviced many inverters and the most likely failure that would emit sparks etc is failed output semiconductors.
One cannot really use an inverter to charge the batteries, like you did, UNLESS the batteries were completely isolated from the Generators wiring, and even then, your inverter, still may not have enough power to do this. As this is NOT what it was designed for.
Really an inverter is used to step up the Voltage from 12/24 Volts DC, batteries to 120/230 V AC.
Now again, one could use it, to then have a Battery Charger plugged into that, and use the output from the battery charger to charge some "Other" batteries, but that seems a bit roundabout.
Yes the Inverter will charge it's OWN batteries, BUT ONLY if that is the ONLY thing connected to the inverter.

The laws of physics dictate that at each energy convertion loss will occur. In fact the loss trying to get wind to generate energy to charge is highly inefficient. To do resarch on this search google for "perpetual motion machines". You will see that the laws of physics will not crate free energy this way. You might get 1 amp at most from a generator while the inverter is drawing 20 amps from the battery.
