Great thread this. @DustyHiker to give you a practical figure from my own experience — I've got a 200W panel flat on a Sprinter and in December/January around the Midlands I'm typically seeing...

TH_OffGrid | 847 posts @WhatsAFuse4 yes, running almost identical setup actually - DCC40S feeding a 200Ah LiFePO4 (Epoch in my case).

I've got a Cerbo GX on my system and whilst the VRM portal is decent enough, I'm not keen on relying on cloud access just to see what my own batteries are doing.

@OffGridJess had almost exactly this on my shepherd's hut build last summer with a Victron SmartSolar.

I picked up four 200W "Grade A" monocrystalline panels off eBay back in March — total outlay about £180 delivered, which felt like a gamble at the time.

Not a camper setup but running a Fogstar Drift 100Ah in my garden office and had a BMS dropout that stumped me for weeks.

Great thread, @MartinTaylor. I've had a SmartShunt talking to a Pi 4 for about eight months now using the VE.Direct to USB cable — dead straightforward once you've got the vedirect.py library...
GrumpyWanderer | 📍 Array | ⚡ Solar @BayLisa had this exact faff on my setup. Check your absorption voltage — if it's set too close to your battery's resting voltage the MPPT thinks it's done when...

@RobRobinson78 the 3000VA unit is right on the edge with a kettle — most draw 2800-3000W alone. A few things worth checking: PowerAssist threshold — in VE.Configure, look at your AC input...

Good shout @BigAl31, the EU22i is a cracking bit of kit for exactly this scenario. I run a similar hybrid setup — 600W solar with a 300Ah lithium bank, and an older Honda EU20i as the cavalry when...

AlisonHughes | 1,203 posts | ⚡ Solar Addict @ExFirefighter One thing nobody's mentioned yet - provenance matters enormously with secondhand cells.

Been scratching my head with this for a few weeks now. Running a MultiPlus 24/2000 with a 200Ah lithium bank (4x 50Ah Winston cells) and a Cerbo GX.

@NeilJackson done exactly this on my cabin setup — mixed a pair of old 150W panels with newer 200W ones on the same Victron 100/30. The main thing I learnt the hard way: mismatched Voc values...

@DougPearce done both, actually — Grade B EVE cells in my previous setup, Fogstar Drift on the current narrowboat. The thing nobody mentions enough: BMS compatibility matters enormously on a boat.

Been running a 280Ah LiFePO4 pack in my van build for about six months now — four EVE 280K cells wired in 4S with a JK BMS (the 200A active balancer version).

FormerMariner36 | 1,204 posts | Array Been through exactly this on my boat before I sorted out the garden office setup — split charge relays were designed for lead-acid and they're frankly a bit...

PW_Sparks | 1,204 posts | Lincolnshire @SamBennett Looks like a few posts got truncated so apologies if we're all saying similar things! To add a different angle — even if your split charge relay...

@StuThompson worth adding to what @BorderVanLifer said — have you checked your bus bar torque on the low-voltage cells?

JimButler | 847 posts @Dizzy83 welcome to the lithium club! One thing that catches a lot of narrowboaters out is the alternator situation — your standard engine alternator absolutely needs a DC-DC...
