Customer Question
We have a 2007 keystone...
We have a 2007 keystone Raptor 39 ft toy hauler, we have a 75 watt solar pannel that chargers 4 deep cycle batteries, my husband left the inverter on and the batteries overcharged, two batteries blew and we replaced. The inverter fan runs now all of the time making us think it is DOA. What are your suggestions?

Hello,

What type of invertor are you using? Was it factory installed?

It sounds like the inverter is going bad. It should not be able to overcharge the batteries as it should shut off when it senses the batteries have reached their proper levels.

The solar panel should also be regulated by the monitor preventing overcharging.

Inverter is factory installed when purchased RV new from the dealer. Is it possible that a spike in power can zap the inverter when hooked up at a park via 50 amp etc.
RV Mechanic: RV Doctor, RVIA Master Certified Technician replied 13 years ago

Yes most definitely. The inverter has very sensitive circuitry that is easily damaged.

There may some serviceable fuses inside the unit that may have blown. The unit needs to be opened up to access the fuses for testing.
