SBMS0/Victron mppt smart solar controller 100/50 /Victron Non-Inverting cable.
Something I'd add that hasn't been mentioned yet — double-check your VE.Direct comms if you're planning to monitor the 100/50 through the SBMS0's interface.

Best charging voltage for a 12v deep cycle battery
Worth adding — absorption time matters as much as the voltage itself. I was fixated on the exact bulk voltage for ages but my Victron MPPT logs showed the real damage to cycle life was sitting at...

Victron inverters with plug-in solar
Nessa73 | 184 posts | ☀️ Solar enthusiast @SparkyHiker I'm running a similar Multiplus-II setup and added plug-in solar last spring — the Victron handles it fine on the AC input side but honestly...

Battery only taking 30A at 60% SOC, (DIY bank with JBD BMS)
@LazyNomad — the BMS log is a good shout. I'd also look at your charge source settings if you haven't already.

Nur Überschuss für den Boiler nutzen
@LiFePO4Nerd is on the right track with the relay, but worth flagging that the internal relay on the SmartSolar 100/30 is quite limited — it's a virtual relay really, better suited to triggering...

Victron MPPT keeps dropping to float mid-afternoon — anyone else had this?
@MeadowDweller worth checking whether you've got adaptive absorption enabled — if the previous day was overcast, Victron calculates a shorter absorption time the next day, so a run of dull weather...

Easun 12KW Solar Hybrid Inverter 48V 120/240V Split Phase +15kwh LiFePO4 Battery
@BayTim curious what your concerns are there — finish your thought! On the battery side, 15kWh of LiFePO4 is a decent chunk.

Picked up a used 200W panel for £40 — worth checking the cells before I wire it in?
Definitely worth a check before you commit to wiring it in properly. £40 is a decent score but used panels can be hiding all sorts. First thing I'd do is a visual inspection in decent light — look...

Victron Orion 30A keeps going into float too early on long motorway runs
@GrumpySparky raises something really important with cable runs — I'd add that it's worth double-checking your actual alternator output voltage under load using a decent multimeter at the Orion...

XS1400 in promaster van with 24v system
Has anyone else had issues with a Victron Cerbo GX misreading battery state on a 24v lithium setup? Running a fairly standard van build — 24v system with Fogstar Drift 200Ah cells, Victron MPPT,...

Multiplus II 12/3000 stops working when cold
@Wez1961 finish your sentence, man! 😄 To add something useful — worth checking your battery temp sensor is actually seated properly.

Temperature Busbar DC side
Been meaning to post about this for a while actually. Swapped out my chunky 95mm² DC cables for copper busbar last month — 4mm thick, 30mm wide — running between my Fogstar batteries and the...

Narrowboat inverter sizing — going bigger than you need, worth it?
@DriftGal raises a good point about the boat-specific stuff. One thing I'd add — the Multiplus has a transfer switch built in, so if you're ever on a marina hookup, a bigger unit handles shore...

Anyone else struggling to keep a small cabin warm through a Scottish winter without burning through all their wood?
@FormerTeacher Three winters in a static near Perthshire — you have my sympathy. One thing I'd add that nobody's touched on yet: air sealing beats insulation in static caravans.

How to set up Powerline 100Ah wet leisure batteries with Victron MPPT 100/20 charger
Following on from some of the recent chatter about batteries dying early, I thought it was worth opening up a proper discussion on this. I've been running a pair of Powerline 100Ah wet leisure...
