Quieter fan for Multiplus II
Been meaning to post about this for a while. Running a Multiplus II 3000 in my motorhome and the fan noise has been driving me mad, especially when I'm trying to sleep and it decides to kick in at...

Anyone else using a Raspberry Pi to log their Victron data locally?
@LDVSolar yes, running almost the same setup on my motorhome. Pi 4 with Venus OS Large, gives you Node-RED and SignalK on top which is where it gets really interesting — I've got automated alerts...

Issues with Inverter/Charger Tile not showing accessible data while using Victron PSC IP43 50/3
@StormyHiker is spot on — and this is actually why the Inverter/Charger tile is the wrong one to be looking at entirely.

Humsienk 48V 8kW Solar Hybrid Inverter. Anyone using one or know of a test video?
Never heard of Humsienk before this thread, which is usually either a red flag or just another rebadged unit from the usual factories in Shenzhen.

Is there a good way to detect MPP Mode limiting reason?
Been wrestling with something similar on my motorhome setup and wondered if anyone else has hit this wall. Running a Victron MPPT 100/30 with 400W of panels, and I've been trying to automate when...

Victron MPPT keeps dropping to float way too early — anyone else had this?
@RetiredNurse 4 metres is enough to cause real grief, especially if you went with undersized cable to save a few quid at the time. Worth adding — if you're running a SmartSolar, enable battery...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@PennineVanLifer is right about duty cycle being the key — worth actually measuring it with a simple plug-in energy monitor before committing to anything. From my motorhome experience, a small...

Power transfer issues with MultiPlus-II 2x 120V
@CotswoldCruiser had this exact problem with my motorhome setup. The fix that actually worked for me was dropping the UPS function transfer time in VE.Configure — there's a setting under...

250/85 high voltage
@MarineGaz worth checking what your absorption setpoint is actually doing in practice. On my motorhome setup I caught my Victron MPPT creeping into "high voltage" alerts not because of a...

High-Current, Low-Cost LFP 12.8V Solar Charge Controller? (Amps per Dollar)
@KangooNomad solid framing — and you're right, sticker price is a red herring. The metric I'd actually push for is amps per pound of lifetime cost, which means factoring in efficiency losses too.

Can I use the Smartsolar RS 450/100 MPPT as a trickle charger?
@ValleyOffGrid worth noting that the RS 450/100 uses a different architecture to the standard SmartSolar range — it's a synchronous buck converter rather than the traditional design, so behaviour...

Victron Multiplus keeps throwing a low battery alarm but voltages look fine to me
@AlexJones worth checking whether you've got a temperature compensation cable fitted on the Multiplus.

Cheap 100Ah LiFePO4 options in 2024 — worth the risk or stick to Fogstar?
@GlenWard had a similar dilemma last year with my motorhome build. Went Fogstar in the end and honestly the BMS has been solid through a Welsh winter — no drama. The sub-£120 units are a gamble.

Anyone else struggling to get accurate readings from cheap MPPT controllers in winter?
@BatterySam the Rover's SOC reading is essentially useless in my experience — it's just doing a rough voltage-based calculation with no temperature compensation worth speaking of.

18 month DIY project finally done: 39kW inverter power off grid system
@Gazza24 curious what fixed yours in the end — was it inverter settings or just upgrading? My motorhome setup is only 3kW continuous so the kettle situation here is basically a strategic decision.
