@LDVWanderer the narrowboat solar struggle is real — I'm not on a boat myself (tiny house on a static plot) but the winter panel angle problem is basically identical.

RussWebb replied: @ShaunKelly87 that's a fair point actually — I suppose I'm just not used to watching it drop and not knowing when the sun's coming back.

Finally took the plunge last month and put together a basic system for my old Transit camper. Ended up spending £187 all in — 100W panel off eBay (£55), a Renogy 20A PWM controller (£22), and a...

Interesting thread — my setup is static caravan rather than marine but LiFePO4 headaches are universal, aren't they? One thing nobody's mentioned yet: low-temperature charging cutoff.

@WrongFuse99 the pitch issue has been well covered already, but one thing nobody's mentioned - have you looked at your actual consumption patterns?

MoorClive | 847 posts | ⭐ Trusted Member Nice one @SteveBurns, sounds like you're going about it sensibly rather than just chucking money at it.

HeathGazer | 634 posts | ⛵ Narrowboat & Cabin Welcome to the forum @MultiPlusGeek — great first thread, and a really practical question. One thing nobody's mentioned yet: make sure your Voc...

LindaPrice87 | 847 posts @Del72 I run almost the exact same setup on my boat — Orion-Tr Smart 30A plus a SmartSolar 100/30.

@PaulaFisher91 makes a solid point about the Daly's balancing window. Worth adding: passive balancing dissipates energy as heat, so if your cells are drifting more than ~10mV at rest after a full...

Trying to get my head around whether a DC-DC charger makes sense in my setup. I've got a static caravan on a plot with no grid connection, running a Victron 12V system with 400Ah of Fogstar...

Squib82 | 203 posts @MultiPlusNerd One thing I haven't seen mentioned yet — check your absorption time settings.

HarbourSam | 📍 South Coast | ⚡ Off-grid since 2019 @Ray1981 worth checking your shunt's calibration resistor value too — a lot of these budget units ship with tolerances way outside spec, which...

Tom1997 | 47 posts @Roger1983 great project, really jealous of that price! I picked up a 30kWh Leaf pack (the 2016-ish "lizard" chemistry one) last year for £550 and it's been solid.

@JH_Power to build on what @RustyRoamer and @MarineKaren are saying — before you even think about panel wattage, sit down and list every device you plan to run along with roughly how many hours...

@MarshSoul worth adding — cold panels produce higher voltage than spec, not lower. Two 200W panels in series on a frosty morning could be pushing your Voc well above that 48V figure.

Chris1966 replied: @Lisa1978 Had almost identical grief with mine last winter. One thing nobody's mentioned yet — what cable size are you running between your batteries and the MultiPlus?

Hey @PaddyGibson, done something similar on my allotment setup — mismatched panels on a single Victron MPPT.

Not a boat setup myself — static caravan — but the wiring principles carry over. One thing worth adding: make sure your fusing is right at the battery terminals, not halfway down the run.

So I've got two 200W panels on my static that I picked up ages ago, and I managed to grab a used 175W panel cheap off eBay.

So I've been scratching my head over my setup for a few weeks now. I've got a Renogy 40A DC-DC charger fitted in my Transit-based van, pulling from the alternator into a 200Ah LiFePO4 leisure...
