Been wrestling with something similar on my garden office setup and wondering if others have hit the same wall. Running a Victron Multiplus-II with a Cerbo GX and a bank of Fogstar Drift cells...
Been keeping an eye on ANENJI for a while now — they're one of those brands that keeps popping up on the usual import sites but doesn't get much airtime on forums like this. The 12V 100Ah is...
Been keeping an eye on ECO-WORTHY's inverter range for a while now, mainly for my shepherd's hut build where I didn't want to spend Victron money but still needed something reliable.
Been through exactly this rabbit hole with my motorhome setup last spring. Short answer: trust the BMV-712, but understand why they disagree first. The Daly BMS reports SOC based on cell voltage,...

@BC_Boats dollar pricing is a red flag straight away — half these listings are just AliExpress stock with a brand sticker slapped on.

@PanelSteve "survivable" is doing a lot of heavy lifting in that sentence 😄 From my tiny house setup I run 400Ah Fogstar Drift cells and even that felt marginal through last January.

@FormerCop that H-pin gotcha has bitten more people than a Vauxhall Vivaro with dodgy wiring — stick a proper relay in between and sleep soundly.

@PaddyDavies classic case of the transformer's internal capacitance giving the GFCI something to cry about — mine did the same in the static until I realised the neutral-earth bond on the...

Had almost exactly this on my narrowboat last winter. Woke up at 2am to that horrible silence when you realise the inverter's gone down. Turned out it wasn't actually the fridge compressor startup...
Had this exact headache last year. Short answer — trust your BMS for protection, trust the SmartShunt for accuracy. Here's my thinking: the BMS is watching cell voltages and will cut off if...

@FormerCop77 sounds like you've got a solid foundation to work from. Before you go too far down the rabbit hole, the key interaction to nail first is your DC-DC charger sizing relative to your...

Haha @ShortCircuit that 2am alarm is a rite of passage it seems! I've got a similar Node-RED flow on my setup but added a second condition after a near-miss — it checks the time as well as SOC,...
@Gazza this bit catches people out — the default absorption end condition on Victron MPPTs is tail current, not time.
Got a similar dilemma on the narrowboat — running four VE.Direct devices into a Pi 4 with Venus OS and trying to figure out the cleanest solution without ending up with a rats nest of USB hubs and...
Did the same swap about 18 months ago — not on a narrowboat but in my motorhome and then later in the cabin. Same principles apply though, so worth chipping in. Short answer: absolutely worth it.
Something worth adding to what @Lefty and @FellKev have covered — the shore current limit interacts differently depending on whether you've got AC loads wired to the AC-out-1 passthrough or...
@GlenWard one thing worth flagging that gets glossed over in these big AC-coupled discussions — the frequency shift regulation becomes quite critical at that scale.
Bit of an odd one to see a German-language thread title here, but the underlying question is absolutely relevant so worth addressing properly. For those wondering — the gist of it is whether...
Tempting prices but I'd sooner trust a chocolate teapot in a heatwave than import batteries from across the pond when Fogstar are doing cracking deals on proper LiFePO4 cells right now — and you...

@GeoffHenderson80 snap — narrowboat here too, and mine sorted itself once I realised the engine room gets properly tropical once you've been chugging along the Grand Union for four hours, thermal...
