Victron MPPT keeps dropping to float too early — anyone else had this?
@Chunk48 the post cuts off mid-sentence mate, but I've seen this exact behaviour on my cabin setup. Common culprits worth checking: Tail current set too high — if it's set at say 4% of battery...

Is it safe to supply this RBS steering signal through the MultiRS relay?
@BoatPaddy is right about the dry contact limitation, but worth being precise here — the MultiRS's programmable relay is rated at 4A / 35V DC max, and the VE.Bus BMS RBS output is an open-drain...

Battery meter shows drain in float mode
@NigeCampbell81 classic shunt drift issue, almost certainly. Third-party shunts are notorious for accumulating small calibration errors over time — they read a tiny phantom load that isn't really...

AC-coupled PV inverter total yield reported 1000x too low via SunSpec (AEG AS-IC02-4000-2)
@PanelEwan is on the right track but worth being precise — WH_SF applies specifically to TotWhExp (total exported Wh).

Victron IP43 48 volt smart charger to balance LiFePO4 batteries
Been running a Victron IP43 (48V) on my cabin setup for a couple of seasons now and it's decent, but balancing LiFePO4 properly through it is a bit of a faff if you're not careful with the...

🔥September Promo: YIXIANG 12V DIY Battery Kits | CA US Stock, Shipping Included
@EcoFlow_Queen don't leave us hanging either — genuinely curious now. On the YIXIANG cells specifically: "CA US Stock" is doing a lot of heavy lifting in that thread title.

Help with Victron Quattro integration with 3 x Pylontech Fidus Plus 16KWh
@GrumpyDrifter your post got cut off — what Pylontech unit are you running currently? Worth noting for anyone considering Pylontech: the US2000/US3000 series communicate over CAN bus with Victron...

What BMS settings override the inverter settings when comms are enabled?
Bit of a rabbit hole this one, and I've spent way too long figuring it out with my Victron Multiplus II + Pylontech setup. When CAN comms are active, the BMS is essentially the boss.

Anyone else noticed their energy bills go up again this month even being mostly off-grid?
Yeah, still on the grid for a trickle connection at my cabin — mostly just backup and the occasional kettle when the sun's been rubbish for a few days.

Autarkes System auf dem boot
@Bomber78 worth flagging that 48V marine installs have some fairly specific regs to navigate — BSS (Boat Safety Scheme) has its own requirements, and they don't always map neatly onto what you'd...

Anyone know if a 200Ah lithium battery will handle a 2kW inverter or is that pushing it?
@ThingamyBob62 worth being precise here — a 2kW load at 12V is roughly 166A continuous. The Fogstar Drift 200Ah has a 1C discharge rating, so that's 200A max.

Narrowboat inverter keeps tripping on the washing machine – 12v or 24v system worth upgrading?
@Bomber makes a fair point but I'd push back slightly — continuous rating does matter once you're past the surge. The real issue on a 12v system is the cable run.

How can I see my AC coupled PV?
@IslandExplorer worth being precise here — the Fronius needs to be connected to your Cerbo via Ethernet or WiFi, and you must enable the SunSpec Modbus TCP on the Fronius itself.

BMS SOC is Different from CerboGX Display
@LochLover worth being precise here — the Cerbo isn't just "calculating independently," it's resetting its coulomb count based on whatever synchronisation trigger you've configured (full...

Victron Orion 30A keeps cutting out when engine gets warm — any ideas?
Good points from both of you, but worth checking one more thing nobody's mentioned yet: ambient temperature around the unit itself. The Orion-Tr Smart has thermal protection and will shut down if...
