I might add, though I choose to use my OEM Progressive Dynamics and hold the Prosine's charger module in "Reserve"
you can also leave the factory converter in place, just disable it by either turning off the breaker or removing the lead from the breaker (Use a wire nut to cap the wire and attach an ID tag in case you need to reconnect it)
Then if the INverter has a problem and needs to go home for repair/replacement,, You still have the OEM converter in place and can "restore" it easily. Way easier than cobbling up something as a temp replacement.
