I've had a ~400AH LiFePo4 battery setup charged from the alternator (180A, 14.2V) checking battery levels (very handwavey I know) via voltage level for years and it's worked well but due to c19 I'll need to be inside running an inverter more often, so I'm setting up a solar system. I'm going with 3 100w rigid/fixed solar panels wired in series into a 100/30 smart solar charger. I was thinking of hooking up a bmv-700 (don't need a second bank to be monitored), but having the solar charger monitor my battery temp is key, so then it's the 702 and once I'm there it's a $20 cable or just get a 712 and not have to do another wiring run, so 712 it's looking to be. Having load monitoring seems useful vs just getting the $40 temp/voltage smartsensor.
1) Would I have been better off just getting a 100/20? It has low voltage shutoff and output load monitoring, and I'm really not going to be pushing 20A often with 300W, though I did like the ability to add on another panel later. Will I get any significant functionality with a bmv 712 + 100/30 over the 100/20 unit?
2) It looks like I should be able to hook up my SmartSolar 100/30 charger to VRM according to documentation, but the portal only shows the GX controller units as eligible devices, and that'd be overkill for my setup. I assumed it'd sync data from the smartsolar charger to VRM when I was online with my phone/laptop etc connected to it - is that possible? The 30 day limit on VictronConnect for historical data is kind of a shame given how much effort has gone into logging.
3) If 2 isn't possible, does anyone have a decent workflow for archiving the CSV dump info from VictronConnect? It just has relative dates back from the current (0, 1, 2) etc... it'd be nice if those could be put into standard unix datetime when exported by grabbing the date from device (which generally sync to master date/time servers whenever online).
I guess naming the dumps by date, then running a script to parse the csv file by running backwards from the current date and adding in a timestamp field would work (could do a simple personal VRM with a js charting library or something).
