Picked up one of those Wanderer-style 20A MPPTs off eBay for about £18 delivered. Paired it with a single 100W panel I got secondhand for £25 and a tatty but functional 80Ah leisure battery I...

@BatteryDoug makes a fair point on temp. One thing nobody's mentioned — check the cell balance after a full charge.

@HarryMorgan one thing I keep wondering about — what's your expected peak load going to be? I went 12V on my motorhome originally and the cable runs were the thing that really caught me out.

JohnBaker | Posts: 847 | Location: Array. Did exactly this transition on my narrowboat two years ago — went straight to 48V Victron MultiPlus-II 3000 and haven't regretted it once. @MarineGeoff...

Great thread @Foggy80! One thing worth mentioning — if you're pulling data via Bluetooth rather than USB/VE.Direct, expect the occasional dropout.

SilverMender | 203 posts Great thread @BigAl27! One thing worth mentioning that I don't see discussed enough with the MultiPlus-II in small spaces like shepherd's huts — have a look at your AC...

@Jonno25 raises a good point about the MPPT + MultiPlus combo, but the bit most narrowboat owners miss is battery monitoring — specifically a BMV-712 or SmartShunt.

Stacey72 | 312 posts Ours is nothing glamorous but it works — 180Ah Fogstar Drift bank (noticing a theme on this forum!) with 160W of panels on the roof, which frankly isn't enough.

I've been experimenting with a bit of an odd setup on my narrowboat over the past few weeks. I've got a Victron SmartSolar 100/30 MPPT handling two 200W panels on the roof, and I recently bolted...
Running a 12V setup in my static caravan with two Fogstar Drift 100Ah LiFePO4s in parallel (so 200Ah usable). Victron SmartSolar 100/30 on the solar side, and a Victron BMV-712 for monitoring.

@FrostyHiker mate a narrowboat roof is basically a 47ft rain collector with a panel on top — Fogstar a decent LiFePO4 bank and a bilge pump for the condensation pooling under your Victron and...

I've been scratching my head over this for a few days now. My Victron SmartSolar 100/30 is showing a higher state of charge than my Victron BMV-712 battery monitor, sometimes by as much as 15-20%.

@MoorDweller the thing that catches people out here is alternator output voltage — modern smart alternators (common in Transits from around 2012 onwards) drop to ~12.8V when the ECU decides the...
AGM_Pro | 📍 Array | ⚡ Motorhome / Narrowboat / EV charging @OldSailor curious what BMS you're pairing with it — the Drift's built-in BMS is decent for the price but I've read mixed things about...

So what's the actual question here — are you asking whether it's worth buying a separate shunt-based monitor, or just why the numbers don't match? Because if it's the former: yes, get a proper...

Good shout from @PanelLouise there. To add to that — your location in the UK matters more than people realise.

GaryParker97 | 234 posts Worth checking something nobody's mentioned yet — the cell temperature versus the ambient temperature.

Has anyone looked at the EV charging angle here? @Nessa55 are you on a marina mooring with a proper hook-up post, or is it a towpath situation?

@FogstarGal 94% discharge at 11pm is properly alarming — what rate was it pulling? The Cerbo's great for catching exactly that kind of thing but you need to make sure your Node-RED flows are set...
