I just replaced an MPPT 100/30 with a 100/50. The 100/30 worked fine. But I can't see the 100/50 in Bluetooth discovery.
I've used an iPhone, iPad, Android, all of which worked fine with the old controller. I tried uninstalling/reinstalling the apps, no luck.
I can see that it appears to be working, the Bulk light comes on when I apply power and then switches over to Absorption (batteries are fully charged).
Did I get a bad unit? Is there any other way to troubleshoot it?
