Turbo43 | Posts: 412 @JennyParker nice setup! One thing I'd flag that nobody's mentioned yet — watch your charging voltage carefully.

Interesting thread — got me wondering about the maths on my own setup. @Kingy your Zoe-off-a-Multiplus situation sounds chaotic but brilliant.

Nobby30 | 867 posts Good points from @Wez1961 and @T5Wanderer already. One thing nobody's mentioned yet — if you do decide to keep the relay in place, make sure it's actually isolated rather than...

I've been scratching my head over this for a couple of weeks now. My Victron SmartSolar 100/30 is showing charge figures that are consistently about 8-10% higher than what my Victron BMV-712 is...

Reply by WhatsAFuse: @WildMechanic to expand on what @VivaroSolar is getting at — your practical options are either a battery-to-battery charger (B2B) between the two banks, or a Victron Orion-Tr...

@Spider6 honestly those numbers are pretty normal for January — don't panic! I've got a similar setup on my garden office and I just plan around it this time of year.

@HeathGazer raises a good point on discharge rates — I've been pushing mine harder than most because I'm charging an EV on the boat occasionally (small top-ups, not full charges) and the current...

Finally got round to sorting the DC-DC charging on my shepherd's hut after running off a single solar array all summer and watching the batteries sulk every overcast week in October. Running a...

Great timing on this thread — I've got almost the same setup! The Fogstar Drift doesn't have a proper CAN bus or VE.Bus BMS interface, so it won't do the full DVCC handshake with the Cerbo.

Lived this exact story on the narrowboat last winter — woke up to a dead 12v system somewhere near Fenny Compton, January, brutal night. What saved me going forward was fitting a small...

Not a van setup but I ran into exactly this sizing headache with my cabin build last year. What tipped the balance for me was thinking about it from the battery's perspective rather than the...

Really timely thread for me as I'm just heading into my second winter doing exactly this in the Lake District — so not the sunniest spot!

Been doing exactly this with my cabin setup. Got the Victron CCGX tied into VRM and it's borderline obsessive — I've got custom alerts set so my phone buzzes if SOC drops below 20%...

Really curious about the alarm thresholds you've all set up in VRM — specifically for SOC low warnings.

@PYQ_Power the VSR isn't pointless but it's doing a different job to the MPPT — your solar handles daytime charging via the SmartSolar, but the VSR handles top-up from the alternator when you're...

BatteryAlan | 1,203 posts @Macca97 lithium on a narrowboat is basically the same maths as anywhere else — you're just doing it whilst slowly annoying fishermen.

Yeah noticed this too @ZI_Sparks — picked up four of the same cells about eight months ago and the price has definitely shifted since then.

GlenSimon | 647 posts Classic voltage drop mystery — my van build taught me this the hard way when I nearly convinced myself my Fogstar cells were lying to me.

CraftyRanger | 487 posts | Cambridgeshire @ShedGenius79 Nice setup! One thing worth mentioning that nobody's touched on — with the DCC50S specifically, make sure your alternator is up to the job...
