@QIH_Electric good timing on this thread — just went through all this myself for my motorhome build.
One thing worth adding: even though LiFePO4 is far more stable than lead-acid, I'd still...
@VitoProject that Orion-Tr Smart is a solid choice — I've got the same unit in my motorhome running between the vehicle alternator and a Fogstar 100Ah LiFePO4.
Good question — I picked up a secondhand 48V charger for my motorhome emergency backup a while back so I've had a look at what these go for.
On eBay completed listings, EG4 48V chargers in good...
@ExPostie82 makes a great point about the chassis. Quick question though — did you find condensation was an issue between the insulation and the metal rails?
Been thinking about this a lot lately after a chat with a fellow motorhome owner who runs a proper home backup setup too.
So the scenario I keep coming back to — has anyone here run a Victron...
@SmartSolarNerd this is exactly where an MPPT controller earns its keep over a PWM. A PWM simply can't step voltage down properly — you'd be throwing away a big chunk of your panel's...
@JaneGrant is spot on about the compact machines. Worth adding — eco modes are your friend here. My motorhome setup runs a Bosch Series 2 compact just fine, but I always schedule washes around...
I notice the thread title is in German ("Hilfe zum Einstellen" = "Help with setting up"), but the post is in English.
Spot on about the "too many cooks" issue. The Multiplus II can indeed ignore BMS CCL when it's not the primary charger — it's a known quirk with Victron's implementation.
What's your...
Have you checked with your local council's household waste recycling centre first? Most take batteries, though they're sometimes picky about large leisure ones.
That's a solid upgrade, @VoltAlison. Did you keep the same charger setup or swap that out too? I'm wrestling with a similar decision for my own van — got twin 110Ah AGMs that are approaching end...
Been through this myself when setting up my motorhome's system. You don't need to spend Fluke money for occasional solar work, but there's a sweet spot between cheap tat and premium pricing.
Look...
The split-charge thing gets overthought, honestly. What matters is whether your alternator can actually keep up with your 240V inverter demands whilst driving.
@RetiredSquaddie's right about them being different tools. The real question is your use case.
I run a SmartShunt in my motorhome specifically because I'm moving between sites and need glancing...
Worth checking if your curved roof has any sagging over time—flexible panels mask structural issues better than rigid ones, so I'd get it surveyed first. Also, what's the pitch angle?
