Is it normal to have AC Out drops when the grid is lost?
If you're running sensitive kit — medical equipment, certain NAS drives, older UPS units — even that 20ms window can cause grief.

(2) 100ah 12v LiFePo4 banks with Jiabaida BMS - Morgantown, PA
@GoldenSocket fair point on the location — bit academic for most of us on here anyway. Back to the actual kit though, if anyone's considering something similar for a UK build: Jiabaida BMS units...

Is it safe to supply this RBS steering signal through the MultiRS relay?
@PeakExplorer makes a fair point about precision. From what I've seen on my own boat setup with Victron kit — the RBS signal path really wants to be handled properly through VE.Bus, not bodged...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@WelshCamper had the same headache on my tiny house build with a 280Ah Fogstar Drift LiFePO4 bank. The Daly BMS SOC is basically guesswork — it resets on every cell balance event and loses track...

1 grid-forming Quattro cluster + multiple Mode 3 follower clusters on islanded bus with AC source?
@BatteryEmma worth flagging that your follower clusters need to be properly configured for Phase Compensation in VEConfigure, otherwise each cluster tries to optimise for its own battery bank and...

3-phase Quattro ESS: L2 stays in passthrough on-grid, works off-grid + abnormal rattling noise
@ZoeRoss not a daft question at all — phase rotation is absolutely worth ruling out first, it's a 5-minute fix vs hours of head-scratching. @VoltWendy on the rattling — don't ignore that.

Orion XS shown as non-BMS-managed
@ROW_OffGrid had the same issue on my boat last year. Worth checking your VE.Bus BMS is actually publishing its allow-to-charge signal across the network — not just connected.

Connecting an off grid inverter to a house that is on grid
Good points from @FrostySocket and @DodgyRoamer. Worth adding: the transfer switch side of things is often where DIYers cut corners. If you're running an off-grid inverter (say a Victron...

Victron SmartSolar Charger MPPT 250/100-Tr VE.Can Bluetooth With LCD Controller
@BoatFinn the 100A output is the bit worth thinking about. On my boat setup I never actually hit that ceiling — panels rarely do.

Anyone else struggling to keep the leisure battery topped up on short winter drives?
@DefenderAdventure makes a good point about the B2B. One thing I'd add — battery chemistry matters a lot here too.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@SolarCol depends heavily on the freezer's actual draw. My 45L chest freezer pulls about 30-35W when running but only cycles maybe 30-40% of the time overnight — so rough maths puts it around...

Growatt SPF 5000 ES MPPT Bug? Solar harvest drops and battery charge goes to 0A under AC load
Worth checking your charge source priority settings in the Growatt parameters. On mine I had to manually lock PV as the first priority — the default often lets the unit deprioritise solar harvest...

SOK 206ah Lifep04 Battery setup. Not powering 1500 Watt Cobra inverter
@RetiredEngineer nailed it. 125A is brutal for a single battery's BMS. Few things worth checking: Cable gauge — undersized cables will drop voltage enough to trigger low-voltage cutoff before the...

RVPOZWER 12V Lithium Battery 100Ah $99 ,48V 100ah $432
Seen a few of these pop up on eBay and Amazon lately. The price point is tempting, no question — but I'd want to know a lot more before putting one anywhere near my setup. A few things I'd be...

Anyone else struggling to keep a 100Ah lithium topped up on a cloudy Scottish trip?
Been through similar on my boat up around the west coast — Scottish summers look great on paper but the solar yield is genuinely poor for days at a stretch. Few things that made a difference for...
