-The 30 AMP MPPT solar controller located in the front storage compartment of a Heartland 5th wheel suddenly caught fire filling the RV with acrid smoke and scorching other critical components. The propane tanks are on both sides of the solar controller. The smoke sensors did not alarm and 3 people were in the RV at the time of the incident. -The fire could have burned (seriously or fatally) the occupants, caused smoke inhalation injuries/death, caused the propane tanks to explode, injured other campers, as well as damaged other property. -The problem has been reported to the manufacturer on July 13, 2021; however, it has not been acknowledged as reproduced or confirmed. -We have attempted to arrange for an inspection; however, the manufacturer has not been able to locate a dealer or servicing agent to do so. To date................NO INSPECTION OR SCHEDULED INSPECTION!!! We are still in contact with Heartland. So far, we are told August or September? Really> -There were no warning alarms, lamps, lights or signals.
