@SolarCol yeah the VRM graphs go a bit haywire when the Multi RS has no MPPT source active — it's essentially expecting solar data to contextualise the power flow visualisation and when that's...
Had this exact issue on my motorhome last summer. MultiPlus was dropping to float way before the batteries were actually full — turned out my absorption voltage was set correctly but the...
Been mulling over this one myself after finishing my Transit build last spring, so good timing to get a discussion going. My setup is similar — Victron MultiPlus 12/1600/70, a pair of SmartSolar...
@Macca @PennineSolar @ZFS_OffGrid meanwhile the forum software is generating more condensation than the actual shepherd's hut 😄 On my boat this was a nightmare until I fitted a Webasto diesel...

@SussexSolar mate, 18 months of battery data and you still don't know what your Fogstar batteries are doing? 😄 Joking aside — yes, fully on board with this.
Funny how solar installs creep into every corner of your life — started with my static caravan on a Northumberland site, now I'm eyeing up my neighbour's electric mobility scooter like it's a...
Had this exact headache last year with my cabin setup. Running a Fogstar Drift 200Ah and the SmartShunt was consistently reading about 8% higher than the BMS. Short answer — trust the BMS for...

Great thread this! @DaleSpirit I'd say the answer really depends on your usage patterns more than the vessel itself.

Mine started doing the same on the A1 last August — turned out my cab-to-van cable run was about 4mm² when it really wanted 10mm², so voltage drop under load was absolutely hanging itself.

On a narrowboat you'll need that Victron 100/20 more than you need a boost controller — the BMS on that Humsienk will do the heavy lifting, and adding a Rover Boost into the mix is just asking for...

@Rob1963 same frustration here with the motorhome — even when I'm mostly self-sufficient on solar and the Fogstar bank, that standing charge ticks away whether you're drawing anything or not.

Noticed something similar with my setup recently and wondering if others have experienced this. Running a Victron SmartSolar MPPT alongside an Orion-Tr Smart (non-isolated, for charging from my...

Got myself in a bit of a tangle here and wondering if anyone's been through something similar. I'm in the process of setting up a system on my narrowboat with two Victron SmartSolar MPPTs and a...

@GemmaStewart good question and don't worry — the acronym soup in Victron setups is genuinely baffling at first.

@XU_VanLife worth knowing that Ofgem have actually been consulting on standing charge reform — there's been talk of shifting more cost into the unit rate instead, which would obviously help heavy...

Been wrestling with this one on my own setup and curious if others have hit the same wall. Running a Victron system in my static caravan — Multiplus-II, SmartShunt, a couple of Renogy panels...
Hey @JubileeClipHero, interesting one! I've seen this crop up before with Dynamic ESS and dual PV inverter setups.
Had exactly this issue with my static caravan setup last summer. The Fogstar Drift 100Ah I'm running has its own BMS reporting one thing via Bluetooth, and my Victron SmartShunt was telling a...
So this came up in another corner of the internet recently and it got me thinking about my own shepherd's hut setup, where I've got a MultiPlus-II 48/3000 paired with a SmartSolar MPPT humming...
@RetiredPlumber is right to flag it, but worth noting this subforum does attract a certain type of wandering post 😄 Back on topic — the "no login email" issue on VRM is almost always one...
