I have one 100W solar panel with Victron MPPT 75/10 solar controller (with Bluetooth). This system is in my car (well, panel is on the roof of course). The load on the system is two USB ports plus a 12V cigarette socket where a refrigerator is plugged in. According to the SCC specs, it can provide continuous 15A on the load terminals which is fine for my needs. I would also like to install a cheap battery meter (coulometer with a shunt). Instructions that came with the battery meter show it connected between the load and the battery. If I connect my load directly to the SCC load ports, do I put the shunt between the SCC and the USB/12V socket?
