Heard a loud pop under the coach as we sat outside enjoying our weekend getaway.. went in the coach and the inverter had faulted.. reset it and went back outside.. within 2 minutes it popped again and the magic white smoke left the unit.. burned up for sure.. what would be a good replacement that will handle lithium also?<br/><br/>Thanks all<br/><br/><em>corrected spelling in topic title -...</em>
