@BorderOffGrid nailed it really. From my experience with emergency backup setups, the BMV-712 is only as good as its calibration — if your shunt isn't sized right or Peukert's exponent is off,...
Got a 200Ah LiFePO4 (Fogstar Drift) sitting in the garage that I mainly keep topped up for emergency backup.
@HelenPhillips raises the Florida heat point but worth adding — high ambient temps will accelerate cell degradation even if the BMS cuts out before thermal runaway.
Been doing this for about 18 months now with a Pi 4 and it's been rock solid. Running VictronConnect data through a Venus OS image directly on the Pi — basically turns it into a GX device without...
Anyone else noticed their Quattro drifting on DC bus voltage readings over time?
Mine's a 48/8000 and I've been running it for about 18 months as part of my emergency backup setup.
One thing nobody's mentioned yet — if you're doing this for a backup/emergency setup like me, VEConfigure has a "shore power assist" mode worth looking at once you've got the config side...
@Inverter_Pro the Cerbo has a CAN-bus port but it's hardwired for VE.Can protocol — RV-C is built on CAN but Victron's implementation isn't a straight plug-and-play with third-party RV-C...
Yeah mine jumped about 40% compared to same quarter last year. Standing charges alone are a joke now.
Honestly it's what pushed me to finally sort out proper battery backup.
Been thinking about this after playing around with my Victron setup lately.
The EVCS wallbox does a decent job of throttling charge current based on available solar — that bit works well enough.
@GeoffRobinson makes the good points on capacity, but worth flagging the inverter side too — a Leaf's onboard charger wants a clean, stable 230V sine wave and will throw a wobbly with anything...
Bit late to this thread but worth adding — had the exact same nightmare with my 100/30 last winter. Turned out the Bluetooth PIN had somehow reset and my phone was silently trying the wrong one in...

Good shout from @ExFarmer79 on the BMS interaction — worth noting that if you're running a Fogstar Drift or similar lithium, the BMS can pull charge acceptance right down under heavy load and the...
Been doing something similar for my emergency backup setup — Pi 4 pulling from a Victron MPPT via VE.Direct into InfluxDB, then Grafana dashboards.
@LutonBuild phase change materials are interesting but honestly for a static the bigger win is usually just blocking solar gain in the first place.
