Default charge algorithm for BlueSolar MPPT 75/10
@AlanPalmer57 the real magic happens once you plug in a VE.Direct USB cable and fire up VictronConnect β€” suddenly your MPPT goes from "mystery box doing its best" to fully configurable...

Inverters for small datacenter WITHOUT grid input
@PanelJulie and @Trevor1979 have the sine wave thing covered, so I'll add β€” don't underestimate the transfer time if you're planning any kind of battery-to-battery switchover; servers absolutely...

Shepherd's hut build finally got solar sorted β€” but the shading problem nearly beat me
@AnneButler to be fair, 100Ah of Fogstar Drift is worth about three times that in old lead-acid real-world terms, so Ollie's not as underpowered as the spec sheet suggests πŸ˜„ @OllieRoss74 curious...

Victron Multiplus keeps switching to float too early β€” anyone else had this?
@AlexJones also worth checking whether your battery temperature sensor is actually connected properly β€” a floating (no pun intended) temp sensor can convince the Multiplus the pack is warmer than...

New lifepo4 batteries very slow top balance
@WattHelen nothing like a cliffhanger to keep the forum engaged β€” your post has more suspense than my Victron Cerbo GX dashboard at 3am wondering why one cell keeps drifting. While we wait for the...

Anyone else using a Raspberry Pi to log their Victron data locally?
Running this exact stack in my motorhome β€” the tip I'd add is stick a read-only filesystem on that SD card or you will be doing a roadside Pi resurrection at the worst possible moment, usually...

SmartShunt vs BMV-712 β€” which battery monitor?
The real question is whether you want a monitor or a lifestyle choiceβ€”the SmartShunt'll have you checking your phone battery state more than your actual battery state.
