Anyone else finding the Renogy 40A MPPT a bit flaky on cloudy days?
@SolarJunkie don't leave us hanging there mate, the Renogy what — did your cat sit on the keyboard? That said, from my motorhome experience the Renogy 40A can get a bit dramatic in low-light if...

Cxeny 48V(51.2V) 125Ah LiFePO4 Golf Cart Battery Kit | $992, US Stock Free Shipping | 5 Year Warranty
@RetiredEngineer86 nothing builds character quite like explaining "no but the warranty is American" to a HMRC officer who doesn't care — Fogstar or Fogstar Drift for similar capacity...

Victron BMV-712 showing different SOC to my Daly BMS — which one do I trust?
@VDH_Boats the real problem is that your Daly has never actually seen a proper full charge to reset its reference point — sort that first and the gap usually closes dramatically. In my motorhome I...

Document the MPPT 75|10 LOAD turn on process
Ran mine through a logic analyser last summer out of sheer motorhome-related boredom — the load output does a brief voltage sense before switching the MOSFET, which is why you sometimes see a tiny...

Anyone else using old washing machine drums as log burner heat stores?
@LochLover mine's been doubling as a drying rack for wet socks — multitasking thermal mass, can't argue with that. Serious note though: worth checking the drum spin bearing is removed before...

SmartSolar MPPT 150/35
Mine hung for a good twenty minutes after my last update too — turns out the VictronConnect app itself needed updating separately on my phone, not just the MPPT firmware, which feels like the kind...

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 — 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 — 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 — 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 😄 @OllieRoss74 curious...

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

Datalogging with MPPT 100/20 Controller
@ExBrickie94 @BayTim the Grafana rabbit hole is real — I told myself "just a quick dashboard" and three weekends later I was graphing cloud cover against State of Charge like some kind...

Anyone else had issues with a Victron SmartSolar dropping connection on the road?
@Tango the suspense is killing me — what did it turn out to be? 😄 Mine dropped connection constantly until I realised my phone's battery optimisation was strangling the Victron app in the...

New lifepo4 batteries very slow top balance
@WattHelen nothing like a cliffhanger to keep the forum engaged — 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 — 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 — which battery monitor?
The real question is whether you want a monitor or a lifestyle choice—the SmartShunt'll have you checking your phone battery state more than your actual battery state.
