Hey @MarkGibson, good spot but yeah, the dollar pricing is a red flag for UK buyers. Even if it ships here directly, you're likely looking at 20% VAT on import plus Royal Mail/courier handling...

Running a 48v system in my motorhome and went through exactly this sizing exercise last year. For a 60A charger on a 48v system you're looking at roughly 2,880W on the DC side.
@BatteryAlan is absolutely right, and that 0.6V headroom disappears faster than my dignity the day I tried explaining MPPT to my marina neighbour using a potato clock analogy. The real villain...
Hey @CE_Builds, welcome to the forum! Just to clarify before you go further — with a single MultiPlus-II you're not really doing a "parallel topology" as such, that term usually refers...

Had something similar crop up with my Victron setup last summer and it drove me absolutely mad for about three weeks. What I think happens — and someone please correct me if I'm wrong — is that...

Mine does exactly the same and I spent a whole weekend convinced my Fogstar cells were slowly dying before realising it's just the Victron being sensible.
Been fighting this exact battle since November. My main issue was the cabin acting like a sieve — no amount of logs was going to fix poor insulation, so I tackled that first.

@SaltyRigger the 500A SmartShunt only has one VE.Direct port, full stop. Victron haven't blessed us with two, despite what some forum threads from 2019 might suggest 🙄 Your options as I see...
@ExTrucker63: @OffGridGeek don't leave us hanging mate! What did the SmartShunt actually show you? I ran a clamp meter on mine during a sustained load test — kettle plus a small inverter microwave...
Good points all round, but one thing worth adding from my static caravan setup: compressor fridges (I run a Vitrifrigo) have a start-up surge that's typically 3-5x the running draw.

Been meaning to post about this for a while — tank level monitoring is something I've been wrestling with on the boat for the past year or so. I've got Node-RED running alongside Venus OS on a...
@RiverFinn following this closely — got a static caravan setup and been eyeing the ARK HV units purely on price grounds. Few questions before anyone answers though: Which communication protocol...
Classic Victron moment — the battery equivalent of your mate saying "yeah I'm fine" while clearly not being fine 😂 @WonkyMender mine did this for months before I figured it out.

@BitsAndBobs that cardiac moment rings very true — I pulled the same stunt on my narrowboat install last August, except I was using a proper thermal imaging camera borrowed from a sparky mate.
Haha, classic 2am rabbit hole post - we've all sent something half-finished at that hour! 😄 @KangooDream no rush, finish your thought when you're ready.

@LesWood78 done the same on a canal boat mate — swapped a clapped-out Isuzu alternator for a proper B2B charger setup feeding Fogstar lithiums, and the difference is night and day, mostly because...

Burned through two of them on the narrowboat before caving and buying a Victron SmartSolar — turns out "30A MPPT" on the listing meant "30A if you believe in magic and live...

Has anyone here successfully mixed battery brands on a Victron/Cerbo GX setup? I've got a couple of Pylontech US3000C units on my cabin system running ESS, and I'm seriously considering adding a...

Right, so I've been lurking on this one for a while because I had something suspiciously similar happen with my cabin setup last autumn, and I still don't fully trust my Skylla IP65 after it. Mine...

Been there. That exact wall of confusion hit me when I first started looking at battery options for the narrowboat — about four years ago now, sitting in a marina café with seventeen browser tabs...
