Don't over analyse this stuff, or get bogged down in details. My system is old with no bells or whistles, but it produces more energy than I require. There are certainly more efficient or modern ways to produce energy than my system, but if you have one bucket of power and you only use 1 x bucket of power does it really matter how fast you can fill 6 buckets of power, and screw every drop out of it you can. A full Enerdrive lithium system is around $15000 (very impressive system too) and it would also produce more energy than I require, and much more efficiently. The Enerdrive is most certainly better at it, but the practical application of it in my case is exactly equal to what I have. I never monitor my system because its designed to fill my needs, it works, I know it works and I have faith in it. The capacity to monitor or test the system would be handy when setting things up, but if I felt the need to continually monitor it after that I suspect that would be because it isn't working for me, or I have no faith in it. I use my Drifter panel to tell me the time and temperature. If I did continually watch the energy reserves on the Drifter and they were falling, Im not going to turn anything off, Im only going to think about it and worry.
My 3 way Dometic fridge works very very well, and has done so for many many years including many 40+ days. I know it works, I know its limitations and Ive know that for many years not because I monitored it but because I drink lots of coffee and my milk was always cold .... then I put a wireless thermometer in it, big mistake because I already knew it worked. Then I became obsessed with the read out on the bloody thermometer. I became less interested in my milk because like forever, it was still cold, I just became obsessing over the lcd of the display. All the time the fridge was just doing what it had been happily doing for years, but what I was now doing was stalking the electronics with no real purpose or practical gain.
I have Victron Smart Solar reg for the blanket I use on the car, but never monitor it. I did to test the panel and the setup but even then with Victron Bluetooth its not auto, you need to be within a certain range, connect the bluetooth each time, and then just looking at the screen wont change a thing. My car battery monitor will set off alarms if it gets low, so I just plug the panel in make sure the reg lights up and then just let it do its thing.
