I have installed a Conext MPPT 80 600 and the SW 4048 at an offgrid cabin and it has been working well after a couple tweaks, I recently setup monitoring as I was seeing the battery run down overnight when I wouldn't have expected it to.
From the graphs it looks like once the battery is charged (often by middle of the day), the MPPT shuts off and doesn't produce any more output, I was thinking that it would still produce enough to satisfy the current load on the SW4548.
So what appears to be happening is the system is charging the battery to 100%, HV cut off is being hit, solar is shutting down and not kicking back in until the battery is down enough to trigger it to recharge.
Any suggestions on how to optimize this? Looks like we are losing alot of daytime sun, I was hoping that the battery would just take up the slack as the sun goes down or clouds come in.
