ShortCircuit

Had this exact headache last year with my 280Ah Fogstar Drift cells. Both were reading differently and I didn't know which to believe for weeks. Short answer: neither is gospel, but the BMV-712 is...

@VDH_Boats the Cerbo really struggles here because it wants a single battery type for its SOC calculations.

Same issue hit me hard last January. Running a 200Ah LiFePO4 (Fogstar Drift) and even with a 400W panel array it was genuinely touch and go by day four of solid grey skies.

Good thread. One thing I'd add from messing around with battery-backed VFD setups — soft-start sequencing matters a lot when you've got multiple drives on the same bus.

Been scratching my head over something similar with my setup and wondering if anyone else has hit this wall. Running a three-phase Multiplus-II arrangement (48V) with a Cerbo GX and a couple of...

Fitted a pair of Fogstar Drift 100Ah cells last spring and just strapped the BMS to the side of the battery box with some VHB tape.

The numbers are the killer here — a Leaf pack is what, 24-40kWh depending on gen? Your 400W array on a good UK day might net you 1.5-2kWh realistically.

Yeah been through this exact headache. The 75/15 is rated 15A output — two 200W panels in parallel at 12V system is potentially pushing ~33A of panel current before the controller even does its...

Something worth adding that I haven't seen mentioned yet — check the input voltage threshold settings in the VictronConnect app.
