so I installed PV system in our Aliner, wired battery to Renogy Rover to loads - so that the load data would be available by Bluetooth - worked great. I shut it down in order to add a fuse in the battery side (I shut off the PV panels first, then battery). This was at home, luckily. Turn it back on (battery first) and no power is going to the loads !! Eff me - what a contrary system. I wound up rewiring loads direct to battery via fuse , and abandoned the load output on the Renogy Rover. This tech needs to be 100% reliable - it is not! .
