Ran genset, now seeing 19+ volts from solar
My MH has been sitting in the driveway for several weeks with the solar panels keeping it charged. NO shore power. Today I went in to run the genset. The voltage meter read 13.6v before I did anyt...

The SS 20 is a PWM controller, with no battery(s) connected it will rise to Voc of the panels that is why you have a means to disconnect a CC input first. The CC output needs to be wired directly to the battery via it's own fuse or breaker as others have said.
Loose connections or corrosion between the battery and genset will cause it to draw more current when starting. This is most likely the fuse failure.
Do a step by step check. Wiring, connections etc. Replace the fuse. Check your 12 volts at the distribution panel. Everything ok. With the converter turned off and the CC disconnected from the battery(s); connect to shore power and turn the converter on. Everything ok. Turn the converter off and disconnect shore power. Start the genset; everything ok. Turn off the genset. Connect the CC; everything ok; now start the genset; everything ok. With the genset and the CC both on turn on the converter; everything ok.
