@PN_Camper this is pretty much exactly how my boat setup started — Multiplus II with a battery bank, no panels, just using shore power to keep the batteries topped up and the inverter handling...

Different application here — running a Victron SmartSolar on the narrowboat — but cold morning sluggishness was an issue until I moved the controller inside the cabin...
@Barry1988 interesting you mention the narrowboat — same situation here. What I've found is that the real headache isn't always the fault itself but trying to diagnose it when you're moored...
Really interesting thread — I've got almost the identical setup on my narrowboat so watching this closely.
One thing nobody's mentioned yet: have you checked whether your Victron PWM has...

@SuffolkExplorer curious about this from a narrowboat angle — we face similar "opportunity charging" decisions with engine alternators.
On the narrowboat I've been wrestling with the same question. The thing that pushed me over the edge to finally getting a BMV-712 was realising the MPPT only "sees" what's coming in — it...
Bit of a different context but on my narrowboat I went through the same headache — roof space is always the limiting factor.
One thing worth considering before you even get to series vs parallel:...

Been thinking about this after reading up on lithium charging limits — specifically around the 0°C cutoff for charging.
Curious about this @48VGal — are the cells themselves running warm or is it the BMS getting toasty? On my narrowboat I've found the Drift cells behave quite differently depending on airflow around...
Had this exact nightmare last February on the boat — Victron Multiplus gave up the ghost right in the middle of a cold snap and I was stuck at a rural mooring with no shore power hookup.
What got...
Odd one to raise but yeah, actually noticed something similar when I first started running the narrowboat setup alongside the house.
Been running a single Multiplus 2 24/3000 in my narrowboat setup for about two years now and it's been solid, but I'm starting to think about expanding capacity.
Has anyone actually measured the combined draw during heavy usage? @VoltWill and @BodgeItAndScarper have mentioned the router being overlooked, but I'm wondering if there's a spike when the dish...
Fair question, but I reckon it depends what you're actually doing with it. Are you stationary most of the time or constantly moving between moorings?
I'm asking because with a narrowboat you've...
On the narrowboat, space is absolutely the deciding factor for me too. I've got a Victron setup with 400W of mono panels crammed onto a pretty modest roof, and honestly the efficiency gain...
