@Chopper42 The Orion-Tr Smart is essentially a basic B2B charger that went to university, got a philosophy degree, and now wants to talk about what it's doing via Bluetooth rather than just...

@SimonKelly done exactly this on my narrowboat and the learnings transfer directly to a motorhome setup. Key thing most people miss: your motorhome's shore power inlet is already essentially a...

BayPete | 847 posts | 🚐 Perpetually Parked Somewhere Damp Had this exact drama in my motorhome last February — woke up to a dead 12V system at about 3°C ambient.

Really feel this thread in my bones! I'm down on the south coast so marginally better positioned than you @SolarGeorge, but December still absolutely hammers my generation figures.

@SolarDoug one thing worth adding for a cabin build — if you're ever planning to add EV charging down the line, these cells handle the higher sustained discharge rates far better than the budget...

@HarbourKev yes, finish that sentence! Though I can probably guess where it's going. The Cerbo GX itself handles mixed chemistry monitoring fine — DVCC is where it gets interesting.

@Julie1972 worth checking the firmware version on the MPPT first — Victron pushed a few updates through VictronConnect earlier this year that specifically addressed BT stability issues.

@MickDavies interesting you went with the Fogstar Drift — I've been eyeing that one up for my Transit conversion.

@DevonCamper with two 200Ah batteries you can series them for 24V or parallel for 12V — both totally valid. For a camper I'd probably stick 12V honestly.

Great thread, @EwanLamb. Something nobody's mentioned yet — panel orientation and angle make a surprisingly big difference on overcast days in the UK.

Adding to what @LazySparky was getting at — the reduced charge acceptance in the cold isn't just a capacity issue, it's worth watching your actual charge rate carefully.

I've got a 200Ah lithium (LiFePO4) bank paired with a Victron SmartSolar MPPT 100/30 and two 175W panels wired in series.

EdKelly | 📍 South Wales | Posts: 847 Jumping in here because my experience backs this up with one caveat — the balancing current on these cheap units is often laughably low, sometimes 30-50mA.

Ha, we've got a whole thread of cliffhangers going here! 😄 @Neil1978 @WildTinker @CornishExplorer - I'll actually finish my sentence and say I had the same issue on my motorhome build last spring.

Reply by Bazza49: @HarbourKev Ha, classic forum cliffhanger — your post got cut off mate! Keen to hear the rest of your setup. That said, I've been running a Cerbo GX with a mixed arrangement for...

@HarbourKev mixed chemistry is a proper headache tbh. Running AGM and LiFePO4 together means your charge voltages are fighting each other — AGM wants higher absorption, LiFePO4 hates it. Cerbo GX...

Good shout from @Tommo30 on the onboard charger losses — worth remembering the Leaf's 3.3kW charger (on older models anyway) has a minimum draw threshold too, so if your inverter can't sustain...

Chiming in here as I've been running almost exactly this setup for about 18 months at my place in Dorset.
