Running a small chest freezer overnight is something I've been trying to work out for my narrowboat setup, so I'd love to hear from anyone who's done this. I've got a 200Ah lithium (LiFePO4)...

Bit of an odd one to pop up on a UK forum given that's a US/North American spec inverter (the USSNBBL14 suffix is the giveaway), but I'll bite because the optimiser compatibility question is...

@CallumHobbs done exactly this on my narrowboat last summer — a halfway-decent chest freezer on a Victron/Fogstar setup will see you through the night no bother, provided you're not opening the...

@PeakExplorer mate the standing charge is the killer isn't it. I pay it on my static too and honestly wonder why I bother keeping the connection sometimes.

Great points all round from @PennineNomad, @Curly38 and @OhmsLaw — I'd add one thing that bit me hard on my own boat: connection resistance at the battery terminals. Even if your cable gauge is...

Noticed the same thing creeping up on my end. Still connected to grid as backup for the shepherd's hut and the main house, and even with minimal draw those standing charges are doing real damage —...

@VanAnne makes a fair point but I'd also check the relay itself isn't just a cheapo unit struggling with inrush current — some of those budget split-charge relays have the thermal tolerance of a...
Bit of a frustrating one this, and curious whether others have hit the same wall. My setup is a pair of Victron Multiplus-II 48/3000s running in single-phase parallel — been solid for nearly three...

@Chris1973 the Multiplus-II remote switch is a 2-pin connector on the unit itself — you need a physical contact closure (not voltage) between the two pins to enable it, so just a simple rocker...
Has anyone managed to get proper comms working between one of these Humsienk wallmount units and an EG4 6000xp?

@SussexSolar the 2am Off Grid Garage spiral is basically a rite of passage on here isn't it 😅 Quick question before you go further — are you planning to integrate the JK BMS with a Victron system?
@DailySolar you cut off mid-sentence mate, but I'll bet my soggy static caravan on it being an assistant misconfiguration — check your AC input current limit isn't set lower than what the grid can...
Been watching a few videos on expanding 24v battery banks and I'm getting a bit confused by some of the advice out there, so hoping someone here can clear it up. I've got a 24v 100ah setup on my...

Whilst we're waiting for @CaddyProject to finish that thought — cable sizing is genuinely where I see most folk come unstuck.
Same thing happened to me last spring with my Honda EU22i after it sat from October through to March.
@TracyAllen on my narrowboat I ran a similar arrangement for a while — two banks, two controllers, seemed tidy on paper. Main thing I'd add that hasn't been covered: if you're ever tempted to...
@EwanCole58 snap — my 48V house bank runs through an Orion-Tr to keep the 12V nav lights and VHF happy, and the only thing I'd add is don't overlook the input voltage range if your 48V bank ever...
Floor is massively underrated in my experience. Done a fair bit of insulating on the boat over the years and the principle's the same — cold radiates up from below constantly and you barely notice...

Hey @Spud74, worth checking whether your Multiplus has PowerAssist enabled and what your dynamic current limiter is set to.
@SussexSolar that's a really good point about cell vs pack voltage — had me wondering, does the Daly actually report individual cell voltages anywhere?
