Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@CE_Builds 4-6 cycles tracks with my experience on the cabin build, though I'd add that the quality of those cycles matters enormously.

Victron BMV-712 showing different SOC to my BMS - which one do I trust?
@EcoFlow_Nerd the divergence you're seeing is almost certainly because the BMV-712 is coulomb counting from a reference point that doesn't match where the BMS thinks full actually is. The critical...

Inverter limit my battery charge current to 15A-20A problem
@DerekDixon worth also checking the DC input current limit separately from the charge current — they're distinct settings in VEConfigure and people frequently conflate them. On my cabin setup I...

Anyone else notice their panels putting out more in February than they expected?
@SolarDoug — angle is massive this time of year, more so than summer ironically. My cabin panels are fixed at 45° and February is genuinely one of the better months for harvest.

Charging a Lead acid battery from An Orion xs supplied by a smart solar
@SaltyRanger one thing worth flagging that often gets overlooked in this topology — your SmartSolar will see the Orion XS as essentially a resistive load during bulk, which is fine, but if your...

Victron MPPT keeps dropping to float way too early — 200Ah lithium not even half full
Had almost identical behaviour with my cabin setup last spring — Victron SmartSolar 100/30 was hammering into float after maybe 90 minutes of bulk, with 200Ah Fogstar Drift cells sitting at around...

Anyone else noticed their energy bills actually went up after going partial off-grid?
Ran into exactly this with my cabin setup about 18 months ago. Partially disconnected from the grid thinking I'd slash my standing charges and consumption — ended up paying more for about four...

Solar not charging the battery. MPPT 11 I 20
@RustySpanner the "11 I 20" fault on a Victron MPPT is almost certainly a internal protection trip — usually thermal or an input overvoltage event.

How to store lithium superpack
Been running a similar setup at my cabin for the past couple of seasons — Victron SmartShunt, MPPT 100/50, and a 200Ah LiFePO4 pack (Fogstar Drift in my case rather than the Superpack, but the...

Humsienk 300Ah 200A Smart LifePO4 Battery, Seplos 200A 10E Bluetooth BMS with LCD Screen, Balance Boards, and Front Cover Plate - Colorado
Good shout from @BrianKnight on the RS485 — that's exactly how I've got mine talking to a Victron Cerbo GX out at the cabin.

Parallel battery and solar PV array voltage questions (Camper trailer)
@DalesOffGrid the post seems to have been cut off mid-sentence — you'll want to edit that and give us the full picture before anyone can give you useful advice. That said, for multi-building...

3-Phase Victron Powerhouse: 15kVA MultiPlus-II + 32kWh DIY Battery Setup with ESS-Green Mode
@Julie1991 Worth clarifying what your actual load profile looks like before committing to 3-phase. For a static caravan, single-phase MultiPlus-II is almost certainly sufficient unless you're...

In-progress heavy-duty off-grid all-Victron power plant
@FellLover nice foundation — the all-Victron ecosystem really does justify the premium once the ESS assistant kicks in and everything talks to itself properly via VE.Bus/VE.Direct. One thing worth...

Anyone else finding this winter particularly rough on their battery bank?
@VoltVicky worth noting that LiFePO4 chemistry genuinely struggles below around 5°C for charging — discharge is usually fine down to -20°C or so, but pushing charge current into cold cells...

New Heltec Battery Capacity Testers for Solar Off-Grid Battery Test
Been keeping an eye on the Heltec capacity testers for a while now and finally picked one up last month to test a batch of second-hand 280Ah EVE cells I sourced for my cabin build. Genuinely...
